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’ whic h 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 m achine measured at the operators’ e ar 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 t o a figure within the range 82 – 88 dB. At equivalent daily noise exposure levels of between 85 – 90 dB ear protection is recommended – it should be used if any window is left open.

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 this machine, read and understand the following section to ensure that 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 bot h. When the machine is not in use the cutting head should be lowered to rest on the ground. In the event of a fault being detected with the machine’s operation it should 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 t o collision or debris on the road.

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 side(s) 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 accorda nce wi th the m anufac t ur er’s r ecommendations.

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

securely attached and that no ne ar e m i ss i ng 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 ball as t 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 l evel .

▲ 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.

ADDITIONAL SAFETY ADVICE Training

Operators need to be competent and fully capable of operating this machine in a safe and efficient way prior to attempting to use it in any public place. We advise therefore that the prospective operator make use of relevant training courses available such as those run by the Agricultural Training Board, Agricultural Colleges, Dealers and McConnel.

Working in Public Places

When working in public places such as roadsides, consideration should be paid to others in the vicinity. Stop the machine immediately when pedestrians, cyclists and horse riders etc. pass. Restart only when they are at a distance that causes no risk to their safety.

Warning Signs

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 Requir ed

“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 sign 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 direct ion, use and colour of t he arr ow 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 given 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 repl ace ‘good com mon sense’ and ‘tot al aw areness’ at all tim es, but will go a long way towards the safe use of your McConnel machine.

FITTING – Tractor requirements

Minimum Tractor Weights - including ballast weight if necessary:

All models – 3250 kg.

Minimum HP Requirements:

All models – 60 HP

Linkage:

Category 2

PTO Shaft:

Tractor must be equipped with a live drive PTO to enable forward motion to be stopped while the flail head continues to oper a t e.

Check Chains/Stabilizers:

Check chains or stabilizers must be fitted and tightened.

TRACTOR PREPARATION

Fitting Tractor Guard: Use tractor with safety glass windows if possible and 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 tractor/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.

Wheel Width: Set wheel widths as wide as possible. Lift Links: Adjust lift links until they are equal length. Tractor Ballast: It is imperative when attaching ‘third-party’ equipment to a tractor that the

maximum possible stability of the machine and tractor combination is achieved – this can be accomplished by the utilization of ‘ballast’ in order to counter-balance the additional equipment added. Front weights may be required 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 am ou nt of r ear ax le 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 tha t 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 combination.  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/s ur face.  Rigidity of implem ent mounting.

Suggestions to increase stability:

 Increasing rear wheel track; a tractor with a wider wheel track is more stable.  Ballasting the wheel; i t is preferable to use external weights but liqui d c an 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 – c are should be taken in selecting the location of the weights t o  ensure they are added to a pos i tion that offers the greatest advantage.  Front axle locking; a ram can be used to ‘lock’ the front axle in work only – locking t he ax l e  moves the ‘balance line’ and can be used to transfer weight to the front axle from the rear

(check with tractor manuf ac turer).

The advice above is offered as a guide for stability only and is not a guide to tractor strength - it is therefore recommended that you consult your tractor manufacturer or local dealer to obtain specific advise 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.

DELIVERY & PRE-ATTACHMENT (Dealer Reference)

Delivery

The machine will be delivered in a partially dismantled condition secured with transport straps and banding. Select a firm level site on which to place the machine before removing the straps, banding and other loose items.

Handling the Machine

Handling of the machine should always be performed using suitable overhead lifting equipment with a minimum safe lifting capacity over and above the maximum weight of the machine. Always ensure the machine is balanced during the lifting procedure and that all bystanders are kept well clear of the raised machine.

Post Delivery Assembly

To allow for a compact shipping state the machine will be delivered with the tension link disconnected from the rocker and the stand legs retracted – these items will need to be correctly installed before initial attachment to a tractor. The procedure is as follows:

Stand Legs

Raise the machine using suitable overhead lifting equipment.

Lower stand legs and secure in position using pins and locking pins – the hole position selected should be at a height that places the gearbox stub axle approximately 75mm (3”) below the height of the tractor’s PTO shaft when the machine is at rest on the ground. Note the hole position used and ensure the equivalent one is used on both sides of the machine

Tension Link Attachment

Request assistance for this task. Operate ‘lift up’ on machine controls sufficient only for dipper arm to clear the ground. Pivot out the dipper arm until the tension link can be connected and secure in position with pin and fixings supplied.

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 tank with oil from the chart or equivalent (see page 18).

 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 leg pin position used

 Unbolt stabiliser from machine and remove the stabiliser nose quadrant pin.

MACHINE ATTACHMENT

Attachment of the machine should always be performed on a firm level site.

CAUTION: During the attachment procedure bystanders must be kept at a safe distance from the machine at all times. Never operate the tractors linkage system or machine controls when persons are standing on, or working between, the tractor and machine.

PTO NOTE: Due to the close coupled design of the machine it is advisable to fit the PTO shaft to the machines gearbox stub axle prior to attaching the machine to the tractor. On initial installation the machine will need to be attached without the PTO fitted in order to measure for the required shaft length – In some cases the machine will then need to be removed from the tractor and subsequently refitted with the PTO pre-attached.

Attach stabiliser to machine frame at points ‘A’ -

selecting a mid-point position initially – secure with nuts and bolts provided. Fit top link at points ‘B’ and secure with pins & lock pins.

Fit lower link balls and spacers int o lower frame

connection points and secure with linkage and lock pins – place spacers to position lower link balls for best alignment with tractor lower links.

Fit PTO shaft to the stub axle of the machines

gearbox. NOTE: for initial installation of a new

machine or attachment to a different tractor refer to PTO note at top of page.

Adjust the drop arms so that lower links are level.

Reverse tractor squarely and centrally to the

machine - set tractor lower links to a height that will permit attachment to lower frame attachment points.

Reverse fully in to attachment points then raise

the tractor linkage until it locks onto the lower link balls on both sides of the machi n e.

1 2 3

Adjust top link to position the stabiliser tongue

for attachment to the tractors top link clevis.

NOTE: Alternative tongues for stabilisers are

available for differing applications.

Attach stabiliser tongue to highest suitable clevis

position that does not interfere with or fou l tractor components - secure with pin and lock pin.

IMPORTANT: Rear of stabiliser tongue should be as close as possible to the bottom of the stabiliser

slot with the machine at rest on the ground – if required change the stabiliser lower attachment points and/or clevis attachment position to achieve this setting. This is a vital requirement to ensure the tongue is located at the slots mid-point when the machine is raised to the work position thus allowing float in each direction.

Attach PTO shaft to the output shaft of the

tractor.

Attach torque chains to convenient locations to

prevent rotation of PTO shaft guarding.

Feed control lines into tractor cab – avoid sharp

bends and keep lines well clear of all moving parts on the machine or tractor.

Connect control lines to the machines control

unit in the tractor cab.

Tighten tractor stabilisers - raise tractor linkage

to lift the machine to its working height.

Remove stand legs from both sides of the

machine.

With machine in work position adjust the top link

to bring machine frame into the vertical p o sition.

Finally, slew the machine into the transport position, replace slew lock pin (transport mode) and close lift ram tap. Attachment is now complete and the machine ready for transportation to the work site.

NOTE: For initial installation refer to running up procedure.

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 measur ing and cutting the shaft is as follow s :

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.

NOTE: 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.

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 s ide - if the holes are mis-aligned carefully operate the angling ram until the holes correspond.

WARNING: Ensure all persons remain at a safe distance whilst operating the 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.

Note: 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.

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.

NOTE: 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 200 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:

NOTE: 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 exc eeded . 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 (-).

RUNNING UP PROCEDURE

Ensure that the rotor control valve is in "STOP" position, start tractor, engage PTO 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.

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 sa fe use o f the mac hine.

CAUTION: Care must always 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 loc ati ons indi cated 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.

OPERATION

Operator Guard

Preparation

READ THE BOOK FIRST

Practice operating the machine in an open space without the rotor running until you are fully familiar with the controls and operation of the machine.

CABLE CONTROLS

Cable controlled machines are supplied with a control unit of the type shown below – the particular version will be dependent on the specification and features of the machine. Versions differ primarily in the number of armhead control levers assembled within the control bank – some versions will have the rotor control lever assembled alongside the armhead control levers as shown below left and others will be supplied with the rotor control lever as a ‘standalone’ unit with its own individual mounting bracket. The armhead control levers all move in a forwards and backwards direction each controlling a specific arm function with the exception of the auto reset lever which operates only in the backward direction (from central ‘off’ position to the backwards ‘on’ position). Where applicable, if a machine is fitted with the optional lift float feature, operation of the lift float will be via an additional electrical switch which will need to be installed in a convenient location in the tractor cab.

NOTE: The illustrations on the following pages show the method of operating all possible functions – depending on individual specifications some features may not be present on your particular machine and therefore will not be applica b le.

UPHILL CUTTING

DOWNHILL CUTTING

CABLE ROTOR CONTROL

On cable rotor control machines the rotor is operated by the lever shown below – from the upright ‘off’ position pushing the lever forward switches the rotor on for downhill cutting and pulling the lever backwards switches the rotor on for uphill cutting. The small pivot locking lever mounted on the side of the control assembly rotates through 180° to lock the rotor in a specific cutting direction – this is a safety feature to avoid changes of rotor direction without first stopping the rotor. To change the direction of cut the rotor lever must be placed in the upright ‘off’ position; when the rotor has stopped rotating completely the pivot locking lever can be turned to the opposing position allowing the control lever to be operated for opposite cutting direction. On some cable operated machines the rotor control lever will be assembled as part of the main bank of controls, whereas on others and all electric models it will be supplied as a ‘standalone’ unit with its own mounting bracket.

CAUTION: Ensure the rotor has stopped turning completely before attempting to change direction - When switched off a rotor can continue to ‘freewheel’ under its own momentum for up to 40 seconds before stopping.

Lock

XTC (Mk2) PROPORTIONAL SWI TCHBOX CO NTRO L S

Machines with XTC Mk2 Proportional Controls (5 service models) will be supplied with the control unit shown below. The units for both electric and cable controlled rotor machines are identical except that for cable versions the rotor control switches B, C & D (shown below) will not provide a function as rotor operation will be controlled by a separate cable lever unit (refer to specific cable rotor control page for operation details of that unit).

Note: 2 sets of control buttons are installed on each side of the unit for operation of Angle Float & Lift Float, both sets of buttons and their LED’s are linked and therefore perform exactly the same function; they are installed to allow for operator preference.

LED Lights

An LED light adjacent to each control button reports the status of that particular function – when the function is selected the LED light will illuminate to confirm the function is active; the light will switch off on de-selection of that function.

Powering the Controls

Activation of power to the control unit is by operation of the red button switch ‘A’ as shown below:

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

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.

CAUTION: 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.

BREAKAWAY

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

NOTE

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

carefully – always be 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

breakback position.

NOTE

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

gradient of work – It will require less forc e 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

POWERED SLEW

The slew feature allows a 95° arc of powered arm movement on the working side from right angles to the tractor to 50 beyond the direct line astern. The 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 t h e ram to bec om e operable again.

CAUTION

Extra care must be taken when working in 'SLEW’ mode with the reach fully in –

IT IS POSSIBLE FOR THE FLAILHEAD TO HIT THE TRACTOR OR MACHINE FRAME.

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.

This plate should not be interfered with in any way.

Any wire caught in the rotor must be immediately removed (see below).

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.

LIFT RAM LOCK TAP Open – only for working Closed – always for transport & storage

TAP TYPE SLEW LOCK ►

Open – only for working Closed – always for transport & storage

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 i llustration 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.

CAUTION!

Where fitted 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

MOVING INTO THE TRANSPORT POSITION

• Select ‘ROTOR OFF’ and wait until the rotor has stopped turning.

• Ensure that the ‘lift’ and ‘angle float’

are switched off.

• Select ‘SLEW’ mode on the control assembly.

• Operate ‘SLEW IN’.

• Operate ‘LIFT’ and ‘REACH’ to position the

machine (see diagram).

• Operate ‘REACH IN’ until the dipper arm contacts the transport cradle.

• Select ‘LIFT UP’ and raise the arms until the tension link is 300mm from the tractor cab.

• Operate ‘ANGLE’ and position the flail head in as compact position as possi bl e. (see tr ans p or t pos it ion)

• Fully screw in the lift ram and slew ram taps.

TRANSPORT POSITION – Head Attached

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 – Head Removed

With the flail head removed the arms are fully folded but the lift ram remains 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.

WARNING!

During transport the 'SLEW’ mode must ALWAYS be selected on the control assembly.

TRANSPORT

When in transport the PTO must be disengaged and the power to the control box switched off.

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 contacting the cab rear cross member.

Transport Height

There is no fixed dimension for transport height. It will vary depending on the height that the machine is carried and the degree of arm fold that the rear of the cab will allow.

For the majority of install ati ons t he tr ans por t height will generally fall between a minimum of 3.45m and a maximum of 3.75m when the machine is correctly folded

Moving From Transport To Work Position (all models)

To revert to the work position' the previous procedures for the relevant models are largely reversed.Remember to unscrew the lift ram tap.

Engaging Drive

Ensure that the rotor control lever 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 flail head in a safe position, increase the engine speed to a high idle and move rotor control lever to 'START’. After initial surging the rotor will run at an even speed.

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

OPERATING SPEEDS

PTO Operating Speed

The correct PTO speeds for opera ti on o f machi nes are as fol lows:

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

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

Engaging Drive

 Ensure the rotor control lever/switch is in the ‘stop’ position before engaging the PTO.  Allow the oil to circulate for a minute or so before operating the armhead controls.  Move the flail head into a safe working position just clear of the material to be cut.  Increase engine speed to a high idle and start the rotor – after initial ‘surging’ the rotor

will run at an even speed.

 Carefully lower the flail head into the work area and begin work.

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.

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 and to abide by them at all times. In addition he must remember that there is a potential for debris to be thrown long distances should it escape the head shrouds. In inhabited areas work should only proceed with extreme caution and any bystanders must be kept away from the potential danger area.

WARNING!

It is the operators responsibility to observe these regulations and to keep

bystanders at a safe distance.

General Working Practices

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

Always :

 Be aware of hazards in the vicinity.  Make sure all guards are in position 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 and stop the tractor engine before making any adjustments.  Check frequently that all must and bolts are tight.  Keep bystanders at a safe distance.

CUTTING PRECAUTIONS

Inspect the work area, remove any dangerous or hazardous materials and note any

immovable obstructions so they can be avoided when working.

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.

WARNING: 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.

WARNING: 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.

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.

WARNING: 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.

Minimum Heights for Overhead Power Lines

Absolute Minimum Exclusion Zones for Specific Overhead Power Lines

Definitions of Exclusion Zones

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 overh ead 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.

HAZARDS & DANGERS

Adverse Slopes

When working with the flailhead high and reach fully in it is possible for the main arm balance to go over centre and take the weight off the lift ram. A restrictor in the gland circuit of the lift ram will prevent sudden unpredictable movements if this should occur - for reasons of safety this restrictor should not be removed.

DANGER!

NEVER REMOVE THE RESTRICTOR

FROM THE LIFT RAM GLAND CIRCUIT.

Never work the machine on adverse slopes with the arms positioned such that the tractor is unbalanced ►

DANGER!

NEVER CUT TO THE BLIND SIDE OF A HEDGE

- it is impossible to see any potential hazards or

dangers and the position of the flail head would allow

debris to be propelled through the hedge towards the

tractor and operator.

DANGER!

NEVER OPERATE THE MACHINE WITH

THE FLAIL HEAD ROLLER REMOVED

DANGER!

WHEN GRASS MOWING THE ROTOR MUST ALWAYS

CUT IN THE UPHILL DIRECTION WITH FRONT HOOD

FITTED AND THE ROLLER POSITIONED BELOW THE

CUTTING HEIGHT OF THE FLAILS

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.

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: with 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 Cable Machines

On cable controlled machines the switch supplied will need to be mounted in a convenient location in the cab. The supply cable from the poppet valve solenoid must be connected into the tractors ignition system - the brown lead is positive and the blue lead is negative.

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.

Depending on the particular machine after market lift float kits will either be frame mounted or ram mounted – they should be fitted and positioned in a location where they do not foul or interfere with other components during normal movements of the machine.

ANGLE FLOAT KIT

Cable operated machines are fitted with Angle Float as standard but is an optional feature on electric models – when activated the feature connects the base and gland circuits of the angle ram to allow free movement of oil in both directions thus allowing the head to automatically angle itself to match the contours of the ground. Refer to specific controls section for details of operation.

Angle Float Off – Requires operator input to adjust flail head angle.

Angle Float On – Flail head automatically angles itself to match the ground contours.

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.

Gearbox Lubrication

Refill the gearbox after an initial 50 hours of use and thereafter at annual or 500 hour intervals, whichever occurs earliest.

Gearbox Capacity:

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.

Drainage of the gearbox for changes of oil is via the drain plug located on the base of the gearbox.

For refilling or for ‘topping up’ the oil remove both 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 plugs and tighten securely.

Grease Points – General Locations

IMPORTANT Grease machine fully before first use.

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 12 Hours

 Change return line filter element. Failure to do so will invalidate the warranty.

Note; factory fitted filter elements are identified differently to replacement elements.

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.  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 12 hours of work.

Annually

 Change tank breather.

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 25 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

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

The 25 micron absolute filter elements (Part No. 8401089) should be changed after the first 12 hours and thereafter at 500-hour intervals. 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

To reduce the risk of pump cavitation it is advisable to replace the 25 micron absolute tank breather (Part No. 8401050) on an annual basis under normal working conditions – for machines operating in dry dusty environments it is recommended that replacement be increased to 6 monthly.

Filtering Capability

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.

CONTROL CABLES

The control cables operate on a push/pull system with the spool centring springs always returning the spool to the neutral position when the handle is released. Care should be taken during installation and operation to ensure that the cables are not trapped or kinked. Any abrasion or damage to the outer casing should be sealed with plastic insulation tape to avoid moisture penetrating. No routine adjustments of the cables are necessary, as they do not stretch. The threaded collar is correctly adjusted when the lever is in a vertical position in its housing allowing an equal amount of travel in either direction.

CAUTION

On no account should any attempt be made to lubricate the cables – these are

assembled with a special ‘lifelong’ lubricant during manufacture and will not require

any additional lubrication.

Note: Take care to ascertain the correct cable connections on both the control unit and the

valve in the event of cable replacement.

PTO SHAFT MAINTENANCE

PTO Shaft Lubrication

The PTO shaft should be lubricated on a regular basis using lithium based grease – each end of the shaft has 2 greasing points; one for lubrication of the universal joint and one for lubricating the rotating fixing ring of the shaft shield – access to the lubrication points is gained by releasing the shaft shield from its fixing ring and sliding it back along the body of the driveshaft – the procedure and lubrication frequency is illustrated below.

Slide the shaft shield back into place after lubrication ensuring the clasps relocate correctly in the fixing ring – always fit torque chains to the shields to stop them from rotating with the shaft during operation.
