VERIFICATION OF WARRANTY REGISTRATION

DEALER WARRANTY INFORMATION & REGISTRATION VERIFICATION

It is imperative that the selling dealer registers this machine with McConnel Limited before delivery to the end user – failure to do so may affect the validity of the machine warranty.

To register machines go to the McConnel Limited web site at www.mcconnel.com, log onto ‘Dealer Inside’ and select the ‘Machine Registration button’ which can be found in the Service Section of the site. Confirm to the customer that the machine has been registered in the section below. Should you experience any problems registering a machine in this manner please contact the McConnel Service Department on 01584 875848.

NOTE TO CUSTOMER / OWNER

Please ensure that the above section above has been completed and signed by the selling dealer to verify that your machine has been registered with McConnel Limited.

IMPORTANT: During the initial ‘bedding in’ period of a new machine it is the customer’s responsibility to regularly inspect all nuts, bolts and hose connections for tightness and re-tighten if required. New hydraulic connections occasionally weep small amounts of oil as the seals and joints settle in – where this occurs it can be cured by re-tightening the connection – refer to torque settings chart below. The tasks stated above should be performed on an hourly basis during the first day of work and at least daily thereafter as part of the machines general maintenance procedure.

POWER ARM INSPECTION AND MAINTENANCE

A daily equipment inspection of the tractor and mower should be conducted before the equipment is used. You may use the inspection sheets to assist with these daily inspections. Any damaged or missing guards should be repaired or replaced before operating the mower. Failure to repair the damaged shield can result in objects being thrown from the mower and possibly hitting the operator or bystander.

Inspect the Mower for Safe Operating Condition

 Make sure the driveline guards and shielding are in place and in good repair.  Inspect the flexible thrown object shielding to assure that they are in place on the

front and rear of the mower head and in good repair. Repair or replace any damaged or missing thrown object shields.

 Ensure the mower cutting height is set high enough to reduce the possibility of the

mower blades contacting the ground. Actual height will be dependent on the ground conditions. Increase the height when working in rough or undulating conditions.

 Inspect for broken, chipped, bent, missing, or severely worn blades. Replace

damaged blades before operating the mower. Ensure the blade retaining bolts and fasteners are secure and tight.

 Ensure all head bolts and nuts are tight.  Lubricate the driveline universal joints and telescoping members daily.  Grease the rotor and roller bearings and inspect their condition.  Inspect for any oil leaks or damaged hoses  Inspect for worn or damaged decals and safety instructions. Replace unreadable,

damaged or missing safety decals.

 Follow the operator’s manual(s) inspection and maintenance instructions for

lubricating parts, and keeping thrown object shielding, driveline guards, rotating parts shields, mower blades and decals in good repair.

Inspect the Tractor for Safe Operating Condition:

 Inspect the controls, lights, SMVs (Slow Moving Vehicle sign), seat belts, and

ROPS to assure that they are in place and in good working order.

 Be sure the tires, wheels, lug bolts/nuts are in good condition.  Make sure the tractor brakes and steering are in proper operating condition.  Follow the operator’s manual(s) inspection and maintenance procedures for

keeping the tractor in good and safe condition before operating.

The inspection sheet on the following page should be kept in this book as a record. A second sheet is included for you to cut out and photocopy or the inspection sheets can be downloaded from our website at; http://www.mcconnel.com/support/aftersales/default.aspx?nav=After Sales

- NOISE STATEMENT -

The equivalent daily personal noise exposure from this machine measured at the operators’ ear is

within the range 78 – 85 dB, these figures apply to a normal distribution of use where the noise fluctuates between zero and maximum. The figures assume that the machine is fitted to a tractor with

a ‘quiet’ cab with the windows closed in a generally open environment. We recommend that the

windows are kept closed. With the cab rear window open the equivalent daily personal noise exposure will increase to a figure within the range 82 – 88 dB. At an equivalent daily noise exposure level of 85 – 90 dB ear protection is recommended and must always be used if any window is left open.

Operating, servicing and maintaining this equipment can expose you to chemicals including gasoline, diesel fuel, lubricants, petroleum products, engine exhaust, carbon monoxide, and phthalates, which are known to the State of

California to cause cancer and birth defects or other reproductive harm. To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area and wear gloves or wash your hands frequently when servicing your vehicle. Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer, birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov. This website, operated by California's Office of Environmental Health Hazard Assessment, provides information about these chemicals and how individuals may be exposed to them.

SAFETY SECTION

This machine has the potential to be extremely dangerous - in the wrong hands it can kill or maim; It is therefore imperative that both owner and operator of the machine reads and understands the following section to ensure they are fully aware of the dangers that do, or may exist, and their responsibilities surrounding the use and operation of the machine. The operator of this machine is responsible not only for their own safety but equally for the safety of others who may come into the close proximity of the machine, as the owner you are responsible for both. When the machine is not in use the cutting head should be lowered to rest on the ground. In the event of any fault being detected with the machine’s operation it must be stopped immediately and not used again until the fault has been corrected by a qualified technician.

POTENTIAL SIGNIFICANT DANGERS ASSOCIATED WITH THE USE OF THIS MACHINE:

▲ Being hit by debris thrown by rotating components. ▲ Being hit by machine parts ejected through damage during use. ▲ Being caught on a rotating power take-off (PTO) shaft. ▲ Being caught in other moving parts i.e.: belts, pulleys and cutting heads. ▲ Electrocution from Overhead Power Lines (by contact with or ‘flashover’ from). ▲ Being hit by cutting heads or machine arms as they move. ▲ Becoming trapped between tractor and machine when hitching or unhitching. ▲ Tractor overbalancing when machine arm is extended. ▲ Injection of high-pressure oil from hydraulic hoses or couplings. ▲ Machine overbalancing when freestanding (out of use). ▲ Road traffic accidents due to collision or debris on the road. ▲ Burn risk from hot components.

BEFORE USING THIS MACHINE YOU MUST:

▲ Ensure you read all sections of the operator handbook. ▲ Ensure the operator is, or has been, properly trained to use the machine. ▲ Ensure the operator has been issued with and reads the operator handbook. ▲ Ensure the operator understands and follows the instructions in operator handbook. ▲ Ensure the tractor front, rear and sides are fitted with metal mesh or polycarbonate

guards of suitable size and strength to protect the operator against thrown debris or parts.

▲ Ensure tractor guards are fitted correctly, are undamaged and kept properly

maintained.

▲ Ensure that all machine guards are in position, are undamaged, and are kept

maintained in accordance with the manufacturer’s recommendations.

▲ Ensure flails and their fixings are of a type recommended by the manufacturer, are

securely attached and that none are missing or damaged.

▲ Ensure hydraulic pipes are carefully and correctly routed to avoid damage by chaffing,

stretching or pinching and that they are held in place with the correct fittings.

▲ Always follow the manufacturer’s instructions for attachment and removal of the

machine from the tractor.

▲ Check that the machine fittings and couplings are in good condition. ▲ Ensure the tractor meets the minimum weight recommendations of the machine’s

manufacturer and that ballast is used as necessary.

▲ Always inspect the work area thoroughly before starting to note obstacles and remove

wire, bottles, cans and other debris.

▲ Use clear suitably sized warning signs to alert others to the nature of the machine

working within that area. Signs should be placed at both ends of the work site. (It is recommended that signs used are of a size and type specified by the Department of Transport and positioned in accordance with their, and the Local Highways Authority, guidelines).

▲ Ensure the operator is protected from noise. Ear defenders should be worn and tractor

cab doors and windows must be kept closed. Machine controls should be routed through proprietary openings in the cab to enable all windows to be shut fully.

▲ Always work at a safe speed taking account of the conditions i.e.: terrain, highway

proximity and obstacles around and above the machine. Extra special attention should be applied to Overhead Power Lines. Some of our machines are capable of reach in excess of 8 metres (26 feet) this means they have the potential to well exceed, by possibly 3 metres (9’ 9”), the lowest legal minimum height of 5.2 metres from the ground for 11,000 and 33,000 volt power lines. It cannot be stressed enough the dangers that surround this capability, it is therefore vital that the operator is fully aware of the maximum height and reach of the machine, and that they are fully conversant with all aspects regarding the safe minimum distances that apply when working with machines in close proximity to Power Lines. (Further information on this subject can be obtained from the Health & Safety Executive or your Local Power Company).

▲ Always disengage the machine, kill the tractor engine, remove and pocket the key

before dismounting for any reason.

▲ Always clear up all debris left at the work area, it may cause hazard to others. ▲ Always ensure when you remove your machine from the tractor that it is left in a safe

and stable position using the stands and props provided and secured if necessary.

WHEN NOT TO USE THIS MACHINE:

▲ Never attempt to use this machine if you have not been trained to do so. ▲ Never use a machine until you have read and understood the operator handbook, are

familiar with it, and practiced the controls.

▲ Never use a machine that is poorly maintained. ▲ Never use a machine if guards are missing or damaged. ▲ Never use a machine on which the hydraulic system shows signs of wear or damage. ▲ Never fit, or use, a machine on a tractor that does not meet the manufacturer’s

minimum specification level.

▲ Never use a machine fitted to a tractor that does not have suitable front, rear and

side(s) cab guarding made of metal mesh or polycarbonate.

▲ Never use the machine if the tractor cab guarding is damaged, deteriorating or badly

fitted.

▲ Never turn a machine cutting head to an angle that causes debris to be ejected

towards the cab.

▲ Never start or continue to work a machine if people are nearby or approaching - Stop

and wait until they are at a safe distance before continuing. WARNING: Some cutting heads may continue to ‘freewheel’ for up to 40 seconds after being stopped.

▲ Never attempt to use a machine on materials in excess of its capability. ▲ Never use a machine to perform a task it has not been designed to do. ▲ Never operate the tractor or machine controls from any position other than from the

driving seat, especially whilst hitching or unhitching the machine.

▲ Never carry out maintenance of a machine or a tractor whilst the engine is running –

the engine should be switched off, the key removed and pocketed.

▲ Never leave a machine unattended in a raised position – it should be lowered to the

ground in a safe position on a level firm site.

▲ Never leave a tractor with the key in or the engine running. ▲ Never carry out maintenance on any part or component of a machine that is raised

unless that part or component has been properly substantially braced or supported.

▲ Never attempt to detect a hydraulic leak with your hand – use a piece of cardboard. ▲ Never allow children near to, or play on, a tractor or machine under any circumstances.

It is advisable that any working area be covered by suitable warning signs and statutory in public places. Signs should be highly visible and well placed in order to give clear advanced warning of the hazard. Contact the Department of Transport or your Local Highways Authority to obtain detailed information on this subject. The latter should be contacted prior to working on the public highway advising them of the time and location of

the intended work asking what is required by way of signs and procedure. – ‘Non-

authorised placement of road signs may create offences under the Highways Act’.

Suggested Warning Signs Required

‘Road works ahead’ warning sign with a supplementary ‘Hedge cutting’ plate. ‘For 1 mile’ or appropriate shorter distance may be added to the plate.

‘Road narrows’ warning signs with supplementary ‘Single file traffic’ plate. White on blue ‘Keep right’ (*) arrow sign on rear of machine.

* Note – this applies to UK Market machines where traffic passes to the right of a machine working in the same direction as the traffic flow. The direction, use and colour of the arrow sign will depend on the country of use and the Local Highway Authorities regulations in the locality.

Use of Warning Signs

▲ On two-way roads one set of signs is needed facing traffic in each direction. ▲ Work should be within 1 mile of the signs. ▲ Work only when visibility is good and at times of low risk e.g.: NOT during ‘rush-hour’. ▲ Vehicles should have an amber-flashing beacon. ▲ Ideally, vehicles should be conspicuously coloured. ▲ Debris should be removed from the road and path as soon as practicable, and at

regular intervals, wearing high visibility clothing and before removing the hazard warning signs.

▲ Collect all road signs promptly when the job is completed.

Although the information stated here covers a wide range of safety subjects it is impossible to predict every eventuality that can occur under differing circumstances whilst operating this machine. No advice given here can replace ‘good common sense’ and ‘total awareness’ at all times, but will go a long way towards the safe use of your McConnel machine.

HSE information sheet

Safe use of rotary flail hedge cutters

Introduction

This information sheet outlines typical hazards when using

most types of tractor-mounted rotary flail hedge cutter. It gives guidance on reducing risks to the operator and others during work with hedge cutters and will help employers, employees and the selfemployed comply with their duties under health and safety law.

All users of rotary flail hedge cutters need to be aware of the particular features of their make/model of hedge cutter when considering the hazards, risks and precautions.

Hazards

The greatest risk of injury comes from contact with the machine’s moving parts and in particular:

entanglement on inadequately guarded power ■ take-off shafts; contact with the cutter head parts, drive belts or ■ pulleys; being struck by the cutting head or machine arm ■ as it moves.

Other risks associated with tractor-mounted hedge cutters can include:

being hit by material or other debris ejected by the ■ cutters; being hit by component parts ejected from the ■ machine; coming into contact with overhead electricity ■ power lines (OHPLs); the tractor overbalancing when the machine arm is ■ extended; injection of high-pressure oil from damaged ■ hydraulic hoses or couplings; being struck by the machine overbalancing when ■ un-hitched from the tractor; road trafﬁc accidents due to collisions with other ■ vehicles either directly or from debris on the road.

Control measures

It is extremely dangerous to carry out any work on a machine while it is under power. The most important safety measure is to follow the ‘safe stop’ procedure before dismounting, or carrying out any maintenance or adjustments, including dealing with a blockage or other problem:

Handbrake on. ■ Controls neutral. ■ Stop engine. ■ Remove key. ■

Guards and machine safety

Check that all guards and other protective devices are in place before starting work. Don’t use the machine if the guards are missing or damaged. Make sure:

the power take-off (PTO) shaft is fully enclosed in a ■ guard along its entire length from the tractor power take-off to the power input connection on the hedge cutter; the tractor rear and side(s) are ﬁtted with protective ■ glazing, metal mesh or polycarbonate guards of a size/strength speciﬁed by the hedge cutter manufacturer to protect the operator against thrown debris or other projectiles; tractor mesh/polycarbonate guards are suitable for ■ the job, undamaged and maintained in accordance with the manufacturer’s instructions; all hedge cutter guards and safety devices ■ are in position, correctly ﬁtted and maintained in accordance with the manufacturer’s recommendations; ﬂails and their ﬁxing heads are the right size for ■ the task. Flails, and their ﬁxings, should be of the type recommended by the manufacturer, securely attached, and should not be missing or damaged; hydraulic pipes are carefully routed to avoid ■ damage; machine ﬁttings and couplings are in good ■ condition.

General guidance on safe working practice

Operators should receive adequate instructions ■ and training to enable them to use the machine safely. Take advantage of relevant training/courses provided by manufacturers/dealers. They will help ensure your safety and that of your staff, and help you get the best performance from your hedge cutter. Make sure the operator reads, understands and ■ follows the instruction manual. Follow the manufacturer’s instructions when ■ hitching or unhitching the machine from the tractor. Do not stand in any position where you may be at risk of being crushed, eg in the area between the back of the tractor and the cutter. Make sure the machine is left in a stable position ■ when it is removed from the tractor, using any stands or props provided, and securing it further if necessary. Do not carry out maintenance on the hedge cutter ■ with the cutting arm/dipper arm raised, unless the arm is properly supported. Check the tractor is at least the minimum weight ■ recommended by the hedge cutter manufacturer. Use ballast as necessary. Inspect the hedge before starting to cut and ■ remove wire, bottles, cans and other debris. Check for any telegraph/electricity pole stays. Damaged stays should be reported to the relevant Telecoms Company/Distribution Network Operator. Use appropriate warning signs to alert others to ■ the hedge-cutting operation where necessary. Work at a safe speed, taking account of the ■ conditions (eg terrain, proximity to the highway, or obstacles). Use safe practices when work needs to be done ■ near OHPLs. Flailhead units on some dipper arms can reach over 5.2 metres, the minimum height of OHPLs above ground level (see Further reading). Clear up debris after cutting if it could be a hazard ■ to others.

Roadside hedges

Take extra care if you are hedge/verge cutting along a road. Consider what measures you will need to control the risks to other road users (eg vehicles, cyclists, pedestrians, or horse riders). For roadside work (on the public highway) there are other legal requirements. For example, there may be obligations to:

display speciﬁc warning signs in deﬁned locations ■ where work is carried out; ﬁt ﬂashing beacons to tractors/machines; ■ clear debris from paths and roads; ■ restrict your working hours. ■

Consult your local authority highways department and the Department for Transport for advice (see Further reading).

TRACTOR REQUIREMENTS

Minimum Tractor Weights (including ballast weight if necessary)

PA5600 & PA6400 Models– 4000kg. PA6500, PA7700T & PA8000T Models – 4500kg.

Minimum HP Requirements:

All models – 75 HP

Linkage:

Category 2

PTO Shaft:

Tractor must be equipped with a live drive PTO to enable forward motion to be stopped while the flailhead continues to operate.

VEHICLE/ TRACTOR PREPARATION

We recommend vehicles be fitted with cabs using safety glass windows and protective guarding when used with our machines. Fit Operator Guard (part no. 73 13 324) using the hooks provided. Shape mesh to cover all vulnerable areas. Remember the driver must be looking through mesh and/or polycarbonate glazing when viewing the flail head in any working position - unless the vehicle/ cab manufacturer can demonstrate that the penetration resistance is equivalent to, or higher than, that provided by mesh/polycarbonate glazing. If the tractor has a roll bar only, a frame must be made to carry both mesh and polycarbonate glazing. The operator should also use personal protective equipment to reduce the risk of serious injury such as; eye protection (mesh visor to EN1731 or safety glasses to EN166), hearing protection to EN352, safety helmet to EN297, gloves, filter mask and high visibility clothing.

Vehicle Ballast: It is imperative when attaching ‘third-party’ equipment to a vehicle that the maximum possible stability of the machine and vehicle combination is achieved – this can be accomplished by the utilisation of ‘ballast’ in order to counter-balance the additional equipment added.

Front weights may be required for rear mounted machines to place 15% of total outfit weight on the front axle for stable transport on the road and to reduce ‘crabbing’ due to the drag of the cutting unit when working on the ground. Rear weights may be required to maintain a reasonable amount of rear axle load on the opposite wheel from the arms when in work; for normal off-ground work i.e. hedge cutting this should be 20% of rear axle weight or more for adequate control, and for ground work i.e. verge mowing with experienced operators, this can be reduced to 10%. All factors must be addressed in order to match the type and nature of the equipment added to the circumstances under which it will be used – in the instance of Power Arm Hedgecutters it must be remembered that the machines centre of gravity during work will be constantly moving and will differ from that during transport mode, therefore balance becomes critical.

Factors that effect stability:

● Centre of gravity of the tractor/machine c o m b ination.

● Geometric conditions, e.g. position of the cutting head and ballast.

● Weight, track width and wheelbase of the tractor.

● Acceleration, braking, turning and the relative position of the cutting head during these operations.

● Ground conditions, e.g. slope, grip, load capability of the soil/surface.

● Rigidity of implement mounting.

Suggestions to increase stability:

● Increasing rear wheel track; a vehicle with a wider wheel track is more stable.

● Ballasting the wheel; it is preferable to use external weights but liquid can be added to around 75% of

the tyre volume – water with anti-freeze or the heavier Calcium Chloride alternative can be used.

● Addition of weights – care should be taken in selecting the location of the weights to ensure they are

added to a position that offers the greatest advantage.

● Front axle locking, check with tractor manufacturer.

The advice above is offered as a guide for stability only and is not a guide to vehicle strength. It is

therefore recommended that you consult your vehicle manufacturer or local dealer to obtain specific

advice on this subject, additionally advice should be sought from a tyre specialist with regard to tyre pressures and ratings suitable for the type and nature of the machine you intend to fit.

AXLE BRACKET/CATCH ASSEMBLY FITTING

Bolt axle plates to the tractor axle at either 1.0m or 1.1m apart - this may necessitate the to removal of the tractor's check chains and/or assister ram brackets, if this is the case the axle plate will include replacement brackets for these functions.

The axle brackets supplied will be accompanied by a fitting sheet with instruction for their attachment to your tractor, follow the instructions exactly as they are specific to your particular make and model of tractor. Replace assister ram(s) if fitted.

Hook the catch assemblies onto the rear of the axle plates, push firmly against the plate and vigorously pivot the catch in a forward and up direction until the spring loaded hook 'snaps' into position. Pass the release cords up into the cab.

On some tractors fitted with auxiliary fuel tanks, there is insufficient space for the spring catches to be fitted, in these instances special axle brackets and catches with a 'pin on' facility are available on request.

Ensure catch-locking pin 'A' is removed.

INITIAL ATTACHMENT TO TRACTOR

The machine will be delivered in a partially dismantled condition, secured with transport strap and banding.

 Choose a firm level site.

 Remove the transport strap, banding

straps and loose items.

 Fill the hydraulic tank to the correct

level using a type and grade of oil

listed in the oil chart (or high quality

equivalent)

 Raise the machine using overhead

lifting equipment with a minimum capacity of 1500kg SWL.

Leave in position at this stage.

 Lower the legs and pin in position

selecting the holes that position the machines gearbox stub shaft approx. 75 mm below the tractors PTO shaft.

- note the leg pin position used.

Locate axle-mounting arms onto the mainframe and secure in position using the correct

nuts and bolts supplied, tighten nuts when correct hole location has been selected - see

following page for details on mounting hole selection.



The correct mounting position is determined by the formula outlined below -

Note: in some cases certain tractors have a low PTO and/or small wheels and therefore have limited ground clearance, where this is the case, the operator must decide what is sufficient ground clearance for his needs; where there is insufficient ground clearance the latch arms can be pivoted down to a lower position. When doing this be aware that it will cause the PTO shaft to become mis-aligned - Ensure you do not exceed the angular misalignment allowed by the PTO shaft manufacturer and remember that this will reduce the working life of the shaft.

With the frame in the vertical position, measure dimensions 'A' and 'B', subtract 'B' from 'A' to obtain measurement 'X'. Measure dimension 'C'. Select mounting holes which position the mounting bars in the end of the latch arms so that dimension 'D' equals dimension 'C' minus measurement 'X' and also when the draft link is horizontal and the rocking draft pin is in the upright position dimensions 'E' and 'F' are equal.

TRACTOR ATTACHMENT

Reverse tractor squarely into position adjacent to the machine and connect the

draft links to the machine - manoeuvre

tractor until both draft pin rockers are vertical.

Lifting equipment may now be removed.

Raise the machine on the tractors linkage sufficient only for the latch bar to fully engage in the axle catch.

The quadrant lever or machine controls must only be operated from the tractor seat. Ensure no one is standing close to or within the linkage arms or bars.

BE AWARE - as lift occurs the

machinery may tilt slightly.

Insert catch lock pins.

Raise the machine on the tractors linkage until the frame is vertical.

Fit top link.

Measure PTO shaft and cut to dimension

shown - see diagram opposite and refer to

PTO installation section for further details.

For subsequent use on different tractors measure again; there must be a minimum of 6" (150mm) shaft overlap.

Fit PTO shaft in position.

Attach the torque chains to a convenient location to prevent rotation of the shaft guards.

Fit machine controls into the cab.

Request Assistance

Operate 'Lift Up' on machine controls sufficient only for the dipper arm to clear the ground. Pivot out the dipper until the tension link can be reconnected.

Raise the stand legs into the work position

and secure with their pins - see diagram

opposite.

Tighten check chains and/or stabiliser bars.

The machine should now be carefully operated throughout its full range of movements to check hoses are not being strained, pinched, chafed or kinked, and that all movements are functioning correctly.

The machine can now be folded into the transport position ready to proceed to the work

site - Refer to the section on Transport Position for details on this subject.

REMOVAL FROM TRACTOR (Axle Mounted Machines)

Removal of the machine must always be performed on a firm level site. Keep all bystanders at a safe distance from the machine.

Never stand between tractor and machine with the tractor running or when operating the tractor’s draft

links. Ensure hydraulics are set to position control.

 Fit and secure the machine’s parking legs.

 Position the arms at approximately half reach

directly to the rear of the machine with the flail

head approximately 600mm (24”) off the

ground.

 Remove axle latch security pins.

 Take machine’s weight on draft links sufficient

to allow the top link to be disconnected, then remove the top link.

 From the tractor cab; release the latch catches

by pulling their cords.

 Operate the draft links to lower the machine to

the ground. Check PTO is still fully engaged.

 Level the machine by gently pushing the

flailhead downwards against the ground using the machine’s controls.

 Disconnect draft links, PTO shaft and remove

the control unit from the tractor cab. Store electric control units in a warm, dry and clean environment.

 Carefully drive tractor clear of the machine.

Hitch Types & Removal

Illustrations show the 3 different types of hitches used on axle mounted machines and the removal method for ‘non-fixed’ versions.

PTO DRIVESHAFT INSTALLATION

The PTO driveshaft attaches between the tractor and the machine gearbox to transfer the power required to the run and operate the machine – it is important to achieve the correct shaft length to avoid risk of it ‘bottoming out’ when raising or lowering the machine. The procedure for measuring and cutting the shaft is as follows:

Measuring the PTO Shaft

With the machine attached to the tractor in the working position measure the horizontal distance ‘A’ from the tractor’s PTO to the input shaft on the machines gearbox and

subtract 75mm (3”) – this figure is the required shaft length.

Place the fully closed PTO shaft on the ground and measure its overall length, if the shaft is shorter than the required length you can use it without

the need to shorten - providing it

allows for a minimum 150mm (6”) overlap when fitted.

If the shaft is longer subtract the required shaft length plus an

additional 75mm (3”) - the resulting

figure is the excess length that will need to be removed from each half of the shaft.

Cutting the PTO Shaft

Separate the two halves and using the measurement obtained above shorten both the plastic guarding and the inner steel profile tubes of each shaft by this

same amount. De-burr the cut tubes

with a file to remove rough or sharp edges and thoroughly clean to remove swarf before greasing, assembling and fitting the shaft.

For subsequent use with different tractors the shaft should be measured again to check

suitability – there must be a minimum shaft overlap of 150mm (6”).

Maintenance

To increase the working life of the PTO shaft it should be periodically checked, cleaned

and lubricated – refer to the PTO maintenance section for further details on this subject.

HYDRAULIC OIL

Hydraulic Oil Reservoir

Fill the tank with oil selected from the chart below or a good quality equivalent to a point where the level is between the minimum and maximum marks on the tank gauge. When the machine is initially run the level will drop

as the oil is drawn into the circuit - top back

up as required to the correct level on the gauge.

Always use clean receptacles when handling and transferring oil to avoid moisture or dirt contamination that can damage components and/or reduce machine performance.

Refer to the maintenance section for further information on the subject of hydraulic oil and system filtration.

Reservoir Capacity The oil tank capacity of the machine is approximately 240 Litres.

Recommended Hydraulic Oils

For initial filling of the oil reservoir, periodic oil changes and replenishment purposes the following hydraulic oils, or a good quality equivalent are recommended:

Only use oils that are ISO 18/16/13, NAS7, or cleaner.

FITTING OPERATOR CONTROL UNITS

Fitment of the operator controls in the tractor cab will vary depending on the particular model or specification of machine – the information below lists the differing methods of fitment for the various types of controls available. NOTE: Electric control units work within the range of 12v-16v DC and will require a minimum power supply of 12v DC.

Cable Controls

Cable control units are provided with, and attached to, a mounting bracket – the bracket should be securely fixed to the internal mud wing or cab cladding in a suitable convenient location that offers ease of use without interfering with normal tractor operation. In deciding the final position of the control unit bear in mind the location of the cable run –

make sure the minimum acceptable cable bend radii of 8” (200mm) is not exceeded.

Ensure during fitting that no structural member of the tractor cab or roll bar is drilled or damaged. The cable rotor control valve lever on cable controlled machines will be assembled as a component part of the main bank of controls and therefore shares the same mounting bracket. On electric machines with cable operated rotor control valve the lever will be supplied as a ‘standalone’ unit with its own individual mounting bracket – this should be fitted in the same manner as above adopting the same precautions pertaining to attachment and cable runs.

Electric Controls

Depending on the particular type of control, electric units are supplied either with a mounting bracket or a mounting pillar which should be bolted to the internal mud wing or cab cladding in a suitable convenient location that offers ease of use without interfering with normal tractor operation. Mounting pillars can be bent or twisted to achieve a comfortable working position. Ensure during fitting that no structural member of the tractor cab or roll bar is drilled or damaged. The power supply cable should be connected directly to the tractors battery - do not use cigarette lighter type connections as these prove to be sporadic and unreliable for control applications. Control units are 12 volt DC operated; the brown lead is positive (+) and the blue lead is negative (-).

V4 & Revolution Proportional Controls

V4 & Revolution proportional controls comprise of 2 units; the main control box or control screen (respectively), and the armrest control unit. The control box/screen is supplied with a mounting bracket and suction cup assembly that allows the unit to be mounted on the window of the tractor cab – ensure the surface used is clean and dry and that the unit is mounted in a position where it does not obstruct operator vision. The armrest unit is designed to slide over the armrest of the tractor seat and is held in place with the fixing straps provided. Alternately, a mounting bar is supplied with Revolution controls that can be used should a more permanent installation be required; when fitting the latter ensure that any holes drilled in the tractor cab is are clear of important component and electrical wiring and should not be located in any area where it could affect the safety structure of the cab. The power supply cable should be connected directly to the tractors battery - do not use cigarette lighter type connections as these prove to be sporadic and unreliable for control applications. Control units are 12 volt DC operated; the red lead is positive (+) and the black lead is negative (-).

FLAILHEAD ATTACHMENT

For ease of attachment and safety this procedure is best performed on a firm level site. With the tractor parked alongside the flailhead operate the controls of the machine to position the pivot bracket of the machines head angling mechanism directly behind flailhead with the base of the hose tray (or junction bracket) parallel to the ground. Manoeuvre the flailhead backwards on its roller until the heads attachment bracket is adjacent to the machines pivot bracket. Fit the 4 attachment bolts through the brackets

from the arm side - if the holes are mis-aligned carefully operate the angling ram until the holes correspond.

Ensure all persons remain at a safe distance whilst operating angling function as the geometry of the head angling mechanism produces several pinch risk areas.

With the attachment bolts correctly located through the brackets fit the self-locking nuts and tighten alternately until the brackets are drawn flush before finally tightening them to a

torque setting of 203Nm (150ft.lbs).

Flailhead Hose Attachment

With the flailhead attached to the machine the hydraulic hoses can

now be connected – refer to diagrams opposite. Upper port ‘A’

on the motor connects to junction bracket point ‘A’ on the arm and lower port ‘B’ on the motor connects to junction bracket point ‘B’ on the arm.

If a hose tray is already fitted to the arm it will need to be removed to allow the hoses to be connected to the junction bracket – ensure the hose tray is replaced once the hoses have been connected.

RUNNING UP PROCEDURE

Before initial use of a new machine, all lubrication points must be greased and the gearbox and oil tank levels checked and

where required topped up before attempting to use the machine. See maintenance section for details.

Ensure that the rotor control valve is in ‘STOP’ position, start tractor, engage PTO and allow the oil to circulate through the return line filter for about 5 minutes without operation of the armhead control lever.

Operate the armhead levers through their complete range ensuring that all movements are functioning correctly.

Place the flail head at a safe attitude and move the rotor control to ‘START’ position. After initial fluctuation the rotor should settle to a steady speed. Increase PTO speed to approximately 360 rpm and run for a further five minutes before disengaging and stopping tractor.

Check the hose runs and observe that they are free from any pinching, chaffing, straining or kinks.

Re-check the oil level in the tank-and top up as necessary.

EMERGENCY STOPPING

In all emergency situations machine operation and functions must be stopped immediately; Stop PTO operation using the tractor controls then immediately kill electrical power to the machine using the Off (Emergency Stop) switch on the machine’s control unit.

Auto-Reset Machines

When the Auto-Reset feature is active the machines arm set is capable of unintentional movement even when the PTO is switched off and stationary. Always ensure that electrical power to the machine is switched off using the Off (Emergency Stop) switch on the machine’s control unit in emergency situations and/or when the machine is not being operated.

Cable Operated Machines

In certain conditions, and/or if the Auto-Reset feature is active, the arm sets on cable operated machines possess the potential to move unintentionally, even when the PTO is switched off and stationary, if the levers were to be accidentally operated. Care must be adopted to avoid any movement of the levers when the machine is not being operated. Ensure arm sets are lowered fully to the ground when the machine is parked up or not in use.

PRE-OPERATIONAL CHECKS

Before initial use of a new machine, all lubrication points must be greased and the gearbox and oil tank levels checked and where required topped up before attempting to use the machine.

Check: Oil level in Hydraulic Tank. Check: Oil level in Gearbox.

Check: Compressed length of Top Link rubber damper.

Check: All bolts are tight and that the specific locations indicated above are tightened to the torque figure stated.

OPERATION

Operator Guard

Machine Guards

Before each period of work, check that all the relevant tractor and machine guards are in place and in good working condition. Small splits and abrasions on the lower edges of the flail head rubber flaps are permissible, but should one or more of these cuts or splits become fifty per cent or more of the flap height they should be replaced immediately as they will have become ineffective for debris containment.

Operator Safety

During operation all the tractor windows should be kept firmly closed with the exception of the rear window which may be opened only to the extent that is sufficient to allow entry of electrical or operating cables for the machine into the cab. Should the tractor not be fitted with a 'quiet' cab ear defenders must be worn at all times, failure to heed this warning may result in permanent damage to hearing. Although in normal circumstances a working machine or rotating parts should never be approached it is an additional wise precaution to avoid wearing loose or flapping clothes especially scarves and neckties whilst in close proximity to a machine. The operator should continually guard himself and others from complacency that can arise from familiarity. Never attempt to take 'short cuts', always follow the correct procedures diligently and abide by the restrictions imposed by safety considerations.

REMEMBER: there is only one right way - the safe way!

PRE-WORK PREPARATION & PRECAUTIONS

IMPORTANT: Always read the book first before attempting to operate the machine – practise operating the machine, without the rotor running, in a safe open space until you are fully familiar with all controls and functions of the machine. Only begin using the machine for work when you are confident that you have mastered the controls and operation sufficient for safe use of the machine.

Care must be taken when working with the flailhead close in to avoid contact with the tractor.

Pre-work Machine Checks

Prior to use of the machine always check all bolts are tight and that the torque figures are correct for the specific locations indicated below:

General Work Precautions

Inspect the work area prior to operation, remove any hazardous materials and note any

immovable objects - it may also be a wise precaution to mark these hazards with a visible

marker than can be easily seen from the operating position in the tractor.

If the type of work being undertaken makes this important precaution impractical, always maintain a high degree of alertness and restrict the tractors forward motion to a speed that allows sufficient time to stop the tractor or avoid the hazard before contact is made.

General Working Practice

It is the operator’s responsibility to develop safe working procedures.

Always;

 Be aware of potential hazards in the vicinity of the work area.  Ensure all guards are fitted correctly and in good condition.  Disengage PTO before stopping the engine.  Wait until the flail has stopped running before leaving the tractor seat.  Disengage the PTO, stop the engine, remove and pocket the key before making any

adjustments to the machine.

 Check frequently that all nuts and bolts are tight.  Keep bystanders at a safe distance.

‘Running In’ a New Machine

For the first day’s work with a new machine it is recommended that tractor forward speed is

restricted to 3 km/hr. (2 mph) maximum. This

will allow machine components ‘bed in’ and allow the operator to become familiar with the controls and their response under working conditions whilst operating at a relatively slow speed. If possible, select a first days work that affords mainly light to average cutting with

occasional heavy duty work – during this

period check the tightness of nuts and bolts after; one hour, four hours and again at the end of the day, retightening as and when required.

Switching the Rotor On

For safety reasons, to prevent accidental starting of the rotor, the ‘Rotor On’ switch cannot be activated in a single operation or without first selecting the direction of cut – the procedure for starting the rotor is as follows: Select the required cutting direction - the Rotor On/Off Switch (D) must then be switched upwards and held in position for a minimum of 8 seconds before switching it into the fully down ‘on’ position where it will remain until it is switched off. When the switch is moved to the down position the red LED light below the switch will be lit to signify the rotor is on – if the LED does not light the switch was not held in its up position for long enough and the rotor will not have started, repeat the process again holding the switch upwards for a longer period.

Rotor Start

Switching the Rotor Off

Stopping the rotor is performed by switching either the Rotor Power Switch (D) or the Rotor Direction Switch (E) to the central (off) position – the red LED light will go out to signify the rotor has been switched off.

When the rotor is switched off it will continue to ‘freewheel’ under

its own momentum for up to 40 seconds before finally coming to a standstill – do not leave the tractor cab or attempt to approach the flailhead until the rotor has stopped turning completely.

Select rotor start for required direction (LED will light to indicate the active direction).

Uphill Cutting

Downhill Cutting

Switching Rotor Direction

With the rotor running, changing the rotor cutting direction can only be achieved after first operating ‘rotor stop’, when stop has been selected the specific direction button can then be operated to command the rotor to switch to the desired direction. NOTE: This function has a built in time delay of approximately 8 seconds - this is a machine protection feature that allows the rotor sufficient time to de-accelerate before restarting in the opposite direction. The LED light of the active cutting direction will flash on and off during the slowing down period, when the direction has changed the LED for the new direction will be illuminated.

Switching the Rotor Off

Stopping the rotor is performed by operation of the rotor stop button as illustrated below. When rotor off has been selected the LED light above the button of the active cutting direction will flash on and off for approximately 8 seconds to signify that the rotor has been switched off, after this 8 second period the light will go off completely. NOTE: The rotor will continue to rotate under its own power until it finally comes to a standstill.

When the rotor is switched off it will continue to ‘freewheel’ under

its own momentum for up to 40 seconds before finally coming to a standstill – do not leave the tractor cab or attempt to approach the flailhead until the rotor has stopped turning completely.

Rotor Start (Selection of Rotor Cutting Direction)

Select rotor start for required direction (LED will light to indicate the active direction).

Uphill Cutting

Downhill Cutting

Switching Rotor Direction

Switching the Rotor Off

Stopping the rotor is performed by operation of the rotor stop button as illustrated below. When ‘rotor off’ has been selected the LED light above the button of the active cutting direction will flash on and off at an increasing frequency for approximately 8 seconds to signify that the rotor has been switched off, after this 8 second period the light will go off completely. NOTE: The rotor will continue to rotate under its own power until it finally comes to a standstill.

When the rotor is switched off it will continue to ‘freewheel’ under

its own momentum for up to 40 seconds before finally coming to a

standstill – do not leave the tractor cab or attempt to approach the flailhead until the rotor has stopped turning completely.

CONTROL UNIT CALIBRATION

If for any reason the controls should stop responding the unit will need to be calibrated; the procedure for this is shown below.

Press and release the rotor stop button to enter calibration mode; all led’s will simultaneously flash once to confirm.

Power led will flash on and off continuously whilst the unit is in calibration mode.

With the unit powered off; simultaneously press and hold both rotor direction buttons before then powering on the unit.

When all the led’s light up; release both buttons.

Operate the joystick through its complete range of movements 4 to 5 times then operate each toggle switch fully forwards and fully backwards 4 to 5 times.

Press the rotor stop button once to exit calibration mode; the rotor stop led will flash rapidly to confirm and the power led will stop flashing and remain lit.

BREAKAWAY

The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered.

The breakaway function does not relieve the operator of his responsibility to drive

carefully. Always stay alert and avoid obvious hazards before contact occurs.

Breakaway may occur momentarily during normal work should an extra thick or dense patch of vegetation be encountered. In these instances tractor forward motion may be maintained with care. Where breakaway has occurred as a result of contacting a post or tree etc. the tractor must be halted and the controls of the machine utilised to manoeuvre the head away from the obstacle. Never continue forward motion to drag the head around the obstacle in

the breakback position.

The force required to activate the breakaway system will vary dependent on the

working gradient. It will require less force when working uphill and vice versa.

On mid-cut machines the geometry of the breakaway will cause the head to initially move outwards in addition to rearwards. Therefore be aware that the breakaway action will be impeded if the outer end of the head is working against a steep bank. In this circumstance extra care must be taken during operation to avoid this occurrence. Breakaway occurs at the slew column pivot. When an obstacle is encountered continued forward motion causes the pressure in the slew

ram base to rise until the relief valve setting is exceeded.

With 'Auto Reset' selected When the slew relief valve setting is exceeded oil is displaced from the slew ram into the base of the lift ram which causes the head to rise as the arm pivots backwards to clear the obstruction.

Resetting of the head into the work position occurs automatically.

With 'Slew' selected

When the slew relief valve setting is exceeded oil is displaced from the slew ram allowing the arm to pivot backwards horizontally and the obstacle to be cleared.

Re-setting the head into the work position is carried out manually by selecting 'SLEW OUT' on the control assembly

VFR ARMS – OPERATING CAUTION

The advanced manoeuvrability that VFR armset s offer permits cutting att achments to be positioned extremely close to t he rear and working side of the tractor; this increases the opportunity of tractor and machine to suffer accidental damage from each other. Apply extr eme caution whilst operating the arms et cl ose to the tractor and keep at a safe distance.

Ensure the head attachment and armset remain at a safe distance from the tractor during operation. Damage can occur if the machine and tractor come into contact.

POWERED SLEW

The slew feature allows a 100° arc of powered arm movement on the working side of the tractor – from the position at right angles to the tractor rearwards to 10° beyond the direct line astern - this feature is required to place the machine in the transport position but can also be used to sweep the arm ‘to and fro’ whilst cutting awkward areas and corners thus avoiding the need to constantly re-position the tractor. To operate in this way 'slew' must be selected on the control assembly.

If breakaway occurs the slew motion must be reversed to allow the slew breakaway relief valve to re seat and the ram to become operable again.

Extra care must be taken when working in slew mode with reach fully in – it is possible for the flail head to come into contact with the tractor or machine frame.

Lift Float Mounting Location/Position

LIFT FLOAT KIT for Non EDS Machines (Part No. 8126338)

Without Lift Float With Lift Float

- Will require constant operator input. - Automatically follows ground contours.

LIFT FLOAT (Optional Extra for Ground Work)

Work without lift float requires far more concentration and input from the operator to quickly react and re-adjust to the ground contours often resulting in patches of higher cut material where the head is cutting too high and ‘scalping’ of the ground where it is cutting

too low – in the case of the latter this can lead to increased flail wear, damage, or even

loss of flails.

The Lift float feature is an optional extra for use during mowing work. When the function is activated the pressurised accumulator(s) work in conjunction with the valve and lift ram to take a proportion of the flailheads weight off the flail roller allowing the head to automatically follow the natural contours of the ground; this produces a cleaner more uniform cut without the need for constant operator re-adjustment. On EDS models the function has 3 user settings for differing working conditions – these are soft, medium and

hard. Refer to the relevant control section for details of selecting the required setting.

Operation of the lift float function is as follows: with lift float switched off, position the flailhead approximately 1m clear of the ground before switching the float function on to

charge the accumulator(s) – the arms may drop at this point depending on the current level of retained pressure. Lower the flailhead into the work position, release the lift control and proceed to work. NOTE: wit h the exception of EDS models, occasional operation of

the lift function will be required when working on downhill or uphill slopes and when reaching in or out in order to replenish the oil level within the accumulator(s) to retain optimum float capability.

Lift float operation when supplied as a factory fitted option is controlled from the controls

unit that accompanied the machine (refer to controls section for details), but the feature is

also available for a range of models as an after market kit, in which case operation will either be via an auxiliary switch on cable controlled machines, or by utilisation of the

auxiliary three-position type switch on the control unit of electric controlled machines - this

will allow for selection of ‘lift float alone’ or ‘lift and angle float in unison’ if both features are fitted. Operation of the lift float control for these models will then be as specified in the

main controls section.

Power Connection on Electric Machines

On electric controlled machines power to the unit is via the following connections: Machines with 14 core looms use connection 10 and common connection 11. Machines with 19 core looms use connection 15 and common connection 16. V3 and V4 Non-EDS proportional machines use connections LF and C.

EASY DRIVE SYSTEM (EDS)

The Easy Drive System (EDS) is an optional extra on larger proportional machines with V3, V4 or Revolution digital controls – where fitted it provides ‘hands free’ cruise control operation with automatic head and lift float at greater working speed that increase both safety and efficiency. The system comprises of sensors that measure rotational movement of the rocker pin and pressure variations in the lift ram circuit these are processed and forwarded to the hydraulic system which then regulates the optimum lift ram pressure to allow the arm and head to ‘float’ over changing ground contours. With readings taken and processed every 30 milliseconds the lift ram pressure is constantly and rapidly re-evaluated and adjusted. Any movement of the joystick in the lift plane will automatically de-activate EDS, on

release of the joystick the system will immediately be reverted back to EDS mode - This is

particularly useful feature for manoeuvring the machine around obstructions.

The EDS system has 3 user settings available for differing operating conditions – these are soft, medium and hard. For machines where EDS is installed refer to the specific control information for details of operation.

PARALLEL ARM GEOMETRY

Parallel Arm Geometry This feature enables the operator to adjust the 'in and out' reach of the machines arms, without the need to continuously adjust the 'lift' service in order to compensate for the change in head pivot height - as would be the case with conventional arm geometry.

The performance of this feature is at its most accurate during the mid-range of the reach travel, with some deterioration in performance

being experienced when the outer extremities of reach adjustment are approached.

Angle Float

The selection of the angle float on the controls simultaneously connects both gland and base side of the angling ram to the tank. The ram rod then can extend and retract freely allowing the flail head to automatically follow the contours of the ground. Angle float is an 'operator friendly' mowing feature and can be used singly or in conjunction with lift float.

For the angle float feature to work to its maximum capabilities the flail head must be mounted such that it is balanced about the pivot.

TELESCOPIC DIPPER – PA6500T /PA7700T / PA8000T

PA6500T / PA7700T / PA8000T models are equipped with telescopic dipper arms giving them extended reach capabilities. In normal working conditions, the 'tele' will be pre-set

and the machine operated using the controls in the normal manner - the tele function

mode can be used as an alternative to 'reach' but a slower response to the commands must be expected.

'Tele' will alter the parallel motion geometry, this works best at ground level when the 'tele'

arm is fully extended and at 4 - 5 feet high (1.2m - 1.5m) high when fully in.

FLAILHEAD WIRE TRAP

The flail head is equipped with a wire cutting edge welded into the underside. This is to ensure that the ends of any wire that may be entwined in the rotor are cut and fall within the confines of the flail head.

IMPORTANT: This plate should not be interfered with in any way.

Any wire caught in the rotor must be

immediately removed.

Removing Wire

 Select Rotor Off and wait until it has stopped rotating.

 Stop the tractor and only then remove wire.

 Do not reverse the rotor in an attempt to unwind any wire.

Work Position - Slew lock pin in stowed location

Midcut Arm Transport Position – insert pin to lock

Std/Tele Arm Transport Position – insert pin to lock

MOVING INTO TRANSPORT POSITION

Select 'Rotor Off' and wait until the rotor has stopped turning. Ensure that the lift and angle float are switched off and, on tele models operate 'Tele In' and fully retract the telescopic arms. Select ‘Slew’ mode on the controls and operate ‘Slew In’ to move the arms from the work position into the correct transport position for that particular type of arm.

Insert the transport pin to lock the position -

refer to diagrams opposite and below.

NOTE: When parking up any of the models prior to removal from the tractor with the arm extended to the rear, the selection of the ‘Midcut Lock position’ will permit the tank covers to be raised for access whereas the Standard/Tele position will not.

 Pivot down the transport prop and fix in position with its pin - see diagrams below

 Operate 'Reach In' until the dipper arm contacts the 'stay' on the main arm.

 Operate 'Lift Up' and raise the arms until the tension link is minimum of 300mm from

the tractor cab.

 Disengage the PTO before transporting the unit.

 Operate 'Angle' and position the flail head in a position that makes it as compact as

possible - see transport position.

TRANSPORT POSITION

The machine is transported in line to the rear of the tractor with a minimum of 300mm clearance between the tension link and the rear cross member of the tractor cab.

Transport Position with Flailhead Removed

With the flailhead removed the arms are fully folded but the lift ram remains fully retracted. If the lift ram is extended the weight of the arms will cause the balance of the machine to go ‘over centre’ causing the tension link to crash into the rear cross member of the tractors cab.

During transport the ‘TRANSPORT LOCK’ device must ALWAYS be used.

‘SLEW’ mode MUST be selected on the operator control unit.

4.1m to

4.4m

Approximate Transport Height

Always be aware of the transport height of your machine and proceed with care when manoeuvring near building, bridges and all other overhead obstructions.

TRANSPORTING THE MACHINE

Transport Height

There is no fixed dimension for the transport height as this will vary for differing models and applications i.e. tractor size, carrying height, and degree of arm fold the particular tractor cab will permit. For the majority of installations the transport height will fall within the region of approximately

4.1m to 4.4m. It is advisable that once your machine has been installed on the tractor that it is folded into the transport position and your own measurement taken to ensure you have an accurate figure for the transport height.

Transport Speed

The acceptable speed of transport will vary greatly depending upon the ground conditions. In any conditions avoid driving at a speed which causes exaggerated bouncing as this will put unnecessary strain on the tractors top hitch position and increase the likelihood of the tension link coming into contact with the cab rear cross member.

During transportation of the machine the PTO must be disengaged and power to the control unit switched off.

MOVING FROM TRANSPORT TO WORK

Reverting to the work position is basically a reversal of the previous work to transport procedure.

Always remember to release the slew and lift locking devices before attempting to move the machine from the transport position.

Engaging Drive

Ensure the rotor control lever/switch is in the ‘stop’ position before engaging the PTO shaft. Allow the oil to circulate for a minute or so before operating the armhead levers. Position the flailhead in a safe position, increase the engine speed to a high idle and move the rotor control lever/switch to ‘start’ – after initial ‘surging’ the rotor will run at an even speed.

CAB PROTECTION SYSTEM (Option)

The cab protection system safeguards the rear crossmember of the tractor cab from possible damage caused by the arms coming into contact with it during transportation or when the arms are being manoeuvred directly behind the tractor. The system consists of a ‘shoe stop’ bracket attached to the machine’s rocker and an adjustable strut and socket that bolts to the main frame of the machine.

On initial installation the strut must be adjusted to set it at the correct stop height for the particular application – once set it will not require any further adjustment unless the machine is removed and used on another tractor.

In transport position the rocker must be clear of the cab protection stop by 5mm minimum NOT IN CONTACT.

Clearance Warning Decal ►

When operating the slew function ensure the rocker remains sufficiently clear of the strut at all times. When placing the machine into its transport position the slew function should be operated, ensuring the rocker stop is clear of the strut, until the pillar is into its transport position and the slew locking pin can be installed. The arms can then be fully ‘reached in’ until the dipper arm rests on the transport prop on the main arm and the final operation of ‘lift up’ carried out. When operating ‘lift up’, bring the shoe on the rocker to a position where it is just clear of the

strut, do not bring them into contact, - the gap should be a minimum of 5mm.

In the same manner when moving out of transport operate the ‘lift down’ function first before slewing to ensure that the rocker shoe and the strut are clear of one another.

Ensure rocker shoe is moved clear of the adjustable strut before slewing the arms.

SLEW & LIFT LOCKS

Slew Lock

All machines with slewing capability are fitted with a slew lock – depending on the particular machine this will either be in the form of a lock tap fitted to the slew ram or a slew locking pin that locates through the pillar into the top of the mainframe. The slew function must be ‘locked’ at all times during transportation and storage of the machine and only unlocked for work. The illustrations opposite and below show the different types of slew locks:

PIN TYPE SLEW LOCK (NOTE: PA600 model shown for illustration purposes only)

Lift Ram Lock

Certain machines, predominantly larger models, will be fitted with either one or two lift ram lock taps – on machines where these are fitted the tap(s) should always be closed during transportation and storage of the machine to prevent movement of the arms during transport or when the machine is parked up. The tap lock(s) will be similar to the one illustrated opposite.

Slew and Lift Locks must be in the closed / locked position at all times during machine transportation and storage – open / unlock only for work.

Slew Locked – always for transport & storage Slew Unlocked – only for working

OPERATING SPEEDS

PTO Operating Speed

The correct PTO speeds for operation of machines are as follows:

Gear Machines: 500 - 540 rpm (Max) Piston Machines: 800 - 830 rpm (Max)

Damage to the machine may occur if the maximum PTO speed is exceeded.

Engaging Drive – Gear Machines

 Ensure the Rotor Control Lever/Switch is in the ‘Stop’ position.

 Engage the PTO driveshaft.

 Allow the oil to circulate for a minute or so before operating the armhead levers.

 Position the flailhead in a safe position.

 Increase engine speed to a 'high idle' and move the Rotor Control Lever/Switch to 'On'

selecting the rotation required - after initial surging the rotor will run at an even speed.

Engaging Drive - Piston Machines

 Ensure the Rotor Control Lever/Switch is in the ‘Stop’ position.

 Switch main power 'On'.

 Prime pump and switch pump power 'On'

 Allow the oil to circulate for a minute or so before operating the armhead levers.

 Place the flail head in a safe position.

 Increase engine speed to a 'high idle' and move the Rotor Control Lever/Switch to 'On'

selecting the rotation required - after initial surging the rotor will run at an even speed.

First day use - check tightness of nuts & bolts hourly ►

Tractor Forward Speed

The material being cut will determine the tractor forward speed. Forward speed can be as fast as that which allows the flail head sufficient time to cut the vegetation both efficiently and neatly.

If forward speed is too fast this be indicated by over frequent operation of the breakaway system, a fall off in tractor revs and a poor untidy finish to the work leaving ragged uncut tufts and poorly mulched cuttings.

‘Running In’ a New Machine

For the first days work with a new machine it is recommended that tractor forward speed is

restricted to 3 km/hr (2 mph) maximum. This will

allow machine components ‘bed in’ and allow the operator to become familiar with the controls and their response under working conditions whilst operating at a relatively slow speed. If possible, select a first days work that affords mainly light to average cutting with occasional heavy duty work –

during this period check the tightness of nuts and bolts every hour, retightening as and when required.

OVERHEAD OBSTRUCTIONS

Always be aware the height of the machine is in excess of 4 metres when folded, take care especially when manoeuvring near or under bridges, buildings, power cables or any other obstacles you may encounter when moving your machine.

WORKING ON PUBLIC HIGHWAYS

When working on the public highway it is the operator’s responsibility to familiarise himself with any national and local regulations concerning this type of activity, ensure they are abided with at all times. In addition, it must be remembered that with this type of machine there is a potential for debris to be thrown long distances should it escape the head shrouds. In inhibited areas, work should only proceed with extreme caution and care, all

bystanders must be kept away from the potential danger area - it is your responsibility to

protect the safety of others in the vicinity.

OVERHEAD POWER LINES (OHPLs)

It cannot be stressed enough the dangers involved when working in the vicinity of Overhead Power Lines (OHPLs). Some of our machines are capable of reach in excess of

8 metres (26’); they have the potential to well exceed, by possibly 3 metres (9’ 9”), the

lowest legal minimum height of 5.2 metres from the ground for 11,000 and 33,000 volt power lines. Remember electrocution can occur without actually coming into contact with a power line as electricity can ‘flashover’ when machinery gets close to it.

All operators must read the following information and be aware of the risks and dangers involved when working in the vicinity of Overhead Power Lines (OHPLs).

Wherever possible the safest option is always to avoid working in areas close to OHPLs. Where unavoidable, all operators must perform a risk assessment and implement a safe

procedure and system of work – see following page for details.

All operators should perform a risk assessment before operating the machine within 10m horizontal distance of any OHPLs.

Risk Assessment

Before starting to work near OHPLs you should always assess the risks. The following points should be observed;

Know the risks of contacting OHPLs and the risk of flashover.

Find out the maximum height and maximum vertical reach of your machine.

Find out the location and route of all Power Lines within the work area.

Find out the operating voltage of all Power Lines within the work area.

Contact the local Distribution Network Operator (DNO) who will be able to advise you on

the operating voltage, safe minimum clearance distance for working, and additional precautions required.

Never attempt to operate the machine in exclusion zones.

Always work with extreme caution and plan your work ahead to avoid high risk areas.

If doubt exists do not work in the area – never risk the safety of yourself or others.

Emergency Action for Accidents Involving Electricity

 Never touch an overhead line - even if it has been brought down by machinery, or has

fallen. Never assume lines are dead.

 When a machine is in contact with an overhead line, electrocution is possible if anyone

touches both the machine and the ground. Stay in the machine and lower any raised parts in contact or drive the machine out of the lines if you can.

 If you need to get out to summon help or because of fire, jump out as far as you can

without touching any wires or the machine - keep upright and away.

 Get the electricity company to disconnect the supply. Even if the line appears dead, do

not touch it - automatic switching may reconnect the power.

HEDGECUTTING PROCEDURE

Cut the side and bottom of the field side first. This leaves the maximum thickness of hedge on the road side to prevent the possibility of any debris being thrown through the hedge into the path of oncoming vehicles.

Cut the side and bottom of the road side.

Top cut the hedge to the height required.

FLAIL TYPES

Grass Flails

Designed specifically for general mowing activities – low power usage, ideal for cutting materials of low density.

Universal Boot Flails

Designed for general purpose work - suitable for mowing duties and the cutting of hedges with up to 2 years growth.

Hedge Flails

Double edged flail designed specifically for heavy duty hedge cutting - capable of cutting materials up to 75/80mm diameter. Can be used for mowing work where they produce a good finish but will require considerably more power and reduced forward speed when used for this purpose.

NOTE: Cast flails are more suitable where the work is predominantly hedge cutting as they maintain a sharper cutting edge – forged versions possess a higher degree of durability and are therefore more suitable where the primary function is mowing work and there is increased risk of hitting foreign objects.

Hedge Flails

Double edged flail designed specifically for heavy duty hedge cutting, capable of cutting materials up to 75/80mm diameter. Can be used for mowing work where they produce a good finish but will require considerably more power when used for this purpose. The flails are fitted with rubber stops for both shaft protection and noise reduction purposes.

Competition Flails

Single edged flail designed specifically for heavy duty hedge and grass cutting, capable of dealing with materials up to 75/80mm diameter. When used for mowing work they produce a better finish and performance than double edged flails requiring less power and increased forward speed.

Omega Flails

Double edged flail for use on ‘Omega’ rotors only - designed specifically for heavy duty hedge cutting where they are capable of cutting materials up to 75/80mm diameter. Unique rotor design allows the flail to rotate 360° on its pivot protecting the flail on impact with immovable objects. Not suitable for mowing work.

GENERAL MAINTENANCE

General Lubrication

The example illustration below indicates the general locations of lubrication points - all points should be greased on a daily basis and prior storage of the machine. New machines must be greased prior to first use.

PTO Shaft Lubrication

PTO Gearbox

Check gearbox oil level on new machines prior to first use, top up if required before using the machine. Replace gearbox oil after an initial 50 hours of use and thereafter at annual or 500 hour intervals; whichever occurs earliest.

Gearbox Capacity (Machines ►11/13)

0.7 Litre SAE75W90 Fully Synthetic which

meets the following minimum requirements;

Viscosity at 40°C, cSt, 100.0 min. Viscosity at 100°C, cSt, 17.2 min.

Gearbox Capacity (Machines 11/13 ►)

0.6 Litre SAE75W90 Fully Synthetic which meets the following minimum requirements;

Viscosity at 40°C, cSt, 100.0 min. Viscosity at 100°C, cSt, 17.2 min.

Planetary Gearbox Capacity

0.5 Litre SAE75W90 Fully Synthetic which meets the following minimum requirements;

Viscosity at 40°C, cSt, 100.0 min. Viscosity at 100°C, cSt, 17.2 min.

Drainage of the gearbox for an oil change is via the drain plug located on the base of the gearbox. To refill or for ‘topping up’ remove filler and level plugs indicated opposite and fill gearbox via the filler plug to a point where the oil starts to run from the level plug orifice. Replace both plugs and tighten.

SERVICE SCHEDULE

Every Day

 Grease machine fully prior to work (and prior to storage).

NOTE: New machines must be greased before initial use.

 Check for broken or damaged flails.  Check tightness of flail nuts and bolts.  Visually check for oil leaks and damaged hoses.  Check all guards and safety shields are correctly fitted and undamaged.  Ensure all lights are working and clean.  Check oil level.  Clean the cooler matrix, in dusty conditions more frequent cleaning is required.

After initial 50 Hours

 Change gearbox oil.

Every 25 Hours

 Grease PTO Shaft universal joints and tubes.

Every Week

 Check tightness of all nuts and bolts.  Check gearbox oil level.

 Check for wear on telescopic arm pads – where applicable.

Every 100 Hours

 Grease PTO shaft shield lubrication points.

Every 500 Hours

 Change return line filter element (Every 500 hours or yearly whichever occurs first).

 Change tank breather.  Change gearbox oil.

 Check condition of hydraulic oil and change if required; when changing oil new

return line filter and suction strainer elements should be fitted and return line filter changed again after 100 hours of work.

Cooler Matrix

To ensure maximum efficiency of the cooling system the cooler matrix must be kept as clean as possible to allow air to flow freely through the unit; this is especially important in dry hot arduous conditions where the matrix can rapidly become blocked by dust causing the machine to overheat. The unit is best cleaned using a high pressure air line that will clear blocked areas without risk of damage to the matrix.

HYDRAULIC SYSTEM

Oil Supply Check the oil level in the reservoir daily.

Oil Condition & Replacement

No fixed time period can be quoted for oil changes as operating conditions can vary widely but a visually inspection of the oil will often indicate its current overall state. Signs of a reduction in its condition will be apparent by changes in colour and appearance when compared to new oil. Oil in poor condition can be dark, smell rancid or burnt, or in some cases be yellow, unclear or milky in appearance indicating the presence of air or emulsified water. Moisture resulting from condensation can become entrapped in the oil causing emulsification that can block the return line filter, consequentially the filter system will be by-passed and the oil and any possible contaminants present will continue to circulate without filtration risking damage to hydraulic components. All are indications or conditions that will require replacement of the oil.

Hydraulic oil is a vital component of the machine; contaminated oil is the root cause of 70% of all hydraulic system failures. Contamination can be reduced by the following:

 Cleaning around the reservoir cap before removal, and keeping the tank area clean.

 Use of clean containers when replenishing the system.

 Regular servicing of the filtration system.

Filtration System

Machines are protected by both replaceable 125 micron suction strainers and low pressure 10 micron full flow return line filters – the diagram below is a ‘scaled up’ view illustrating the filtering capability built into the hydraulic system of the machine:

Suction strainers – Stops large contamination in the oil entering the pump

The replaceable 125 micron suction strainers (Part No. 8401097) are fitted within the

hydraulic tank and are ‘screw’ fitted with easy access for removal and replacement.

Return Line Filter– Stops small contamination in the oil entering the hydraulic tank

The 10 micron absolute filter elements (Part No. 8401106) should be changed at 500-hour intervals or annually, whichever occurs first. It is important to note hours worked as if the

filter becomes blocked an internal by-pass within the canister will operate and no symptoms of filter malfunction will occur to jog your memory.

Tank Breather – Stops contamination from the air mixing with the oil

To reduce the risk of pump cavitation the 10 micron absolute tank breather (Part No.

8401137) should be changed at 500-hour intervals or annually, whichever occurs first.

For machines operating in dry dusty environments it is recommended that replacement be

increased to 250-hour intervals or every 6 months, whichever occurs first.

The breather pressurises the fluid trapped in the tank up to 0.3Bar; this is to reduce pump cavitation and reduces the air flow through the breather - extending the filter life. To avoid danger; unscrew the breather two revolutions and then wait until pressure in tank is equal to the atmosphere - the breather can then be removed safely. It is advisable to remove any pressure in the tank before working on the hydraulics as this will reduce the amount of oil split.

Hot Oil & Hot Components

Never attempt to perform service or maintenance work on the machine’s hydraulic system whilst the components and/or their contained oils are hot; machines must be allowed to cool down to a safe temperature state before performing any repairs, service or maintenance tasks.

HYDRAULIC HOSES

The condition of all hoses should be carefully checked during routine service of the machine. Hoses that have been chaffed or damaged on their outer casing should be securely wrapped with waterproof adhesive tape to stop the metal braid from rusting. Hoses that have suffered damage to the metal braid should be changed at the earliest opportunity.

Hose Replacement

Before changing any hoses take the time to study the existing installation as the routing has been carefully calculated to prevent hose damage during operation - always replace hoses in exactly the same location and manner. This is especially important for the flail

hoses where they must be crossed, upper to lower, at the dipper and head pivots.

 Always replace one hose at a time to avoid the risk of wrong connections.

 When the hose is screwed to an additional fitting or union, use a second spanner on

the union to avoid breaking both seals.

 Do not use jointing compound on the threads.

 Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or

trapping before tightening hose end connections.

All Hydraulic Hoses (BSP) now fitted to McConnel Power Arm Hedge/Grass Cutters have ‘soft seal’ connections on both flail and ram circuit hoses.

Recommended torque settings for nut security are as follows:

For hose unions (BSP) fitted in conjunction with bonded seals the recommended torque settings are as follows:

Safety Note:

Soft seal hose connections are capable of holding pressure when the nut is only ‘finger tight’. It is therefore recommended during dismantling that the hose be manually flexed to relieve any residual pressure with the retaining nut slackened prior to complete disassembly.
