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.

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 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 both.
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 to collision or debris on the road.
4
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 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).
5
▲ 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 uses 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.

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 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 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 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 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 replace ‘good common sense’ and ‘total awareness’ at all times,
but will go a long way towards the safe use of your McConnel machine.

VEHICLE / TRACTOR PREPARATION
We recommend vehicles are 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 the 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 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/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.
8
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
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.
9
PRE-ATTACHMENT
The machine will be delivered in a partially dismantled condition secured with transport
strap and banding.
Machine Preparation
Select a firm level site on which to locate

The quadrant lever or machine controls must be
operated from the tractor seat. Ensure no one is
standing on or between the linkage arms or bars.
• Replace the stabiliser quadrant pin and
secure with the ‘R’ clip.
NOTE: The quadrant pin must be fitted in
the lowest hole on the stabiliser in order
that it acts as a ‘bottom stop’ - this will
prevent the machine from dropping when
stopped and permit the tractor’s inbuilt
transport protection system to function
correctly during operation and
transportation.
• Ensure the tractor’s linkage is in ‘position
control’ and the linkage raised sufficiently
to hold the hedgecutter at the correct
height and remove the load from the
quadrant pin.
Never
fit the quadrant pin in a location hole
that locks the stabiliser as this can cause
damage to the machine and/or tractor.
• Adjust the top link to bring the machine
frame into the vertical position.

Check the welded in pins between the stabiliser jaws are in contact with the mounting rail. If not the
machine must be lowered to the ground and the next higher hole on the stabiliser quadrant selected,
the machine raised and contact checked. Repeat again in the third hole if necessary. On subsequent
fitting to the same tractor the hole selected is always used.
• Fit machine controls into the cab
(see page 17)
• Measure PTO and cut to dimension
shown
- refer to maintenance section for
details.
For subsequent use on different tractors
measure again - there must always be a
minimum shaft overlap of 6” (150mm).

Carefully operate the machine through its full range of movements whilst checking that
hoses are not strained, pinched, chaffed or kinked and that all movements are functioning
correctly.
Fold the machine into the transport position (see pages 25 - 27).
The machine is now ready to proceed to the work site.
17
FLAILHEAD ATTACHMENT
Operate machine controls to manoeuvre the
arm into a position that will enable attachment
of the flailhead – the bottom of the hose
junction bracket must be parallel with the
ground.
Refer to ‘Pre operational checks’ for correct bolt
torque settings.
Connect up flail hoses as indicated below.
With the arms at half reach and the flailhead clear of the ground carry out final adjustment
of the lift arm levelling box to bring the main frame horizontal.
18
FITTING CONTROL UNIT IN CAB
The control unit is bolted to a mounting bracket, which may be bolted to the mud wing or
cab cladding in a convenient location - ensure that no structural member of the cab or roll
bar is drilled.
In deciding the final position of the control box remember not to exceed the minimum
acceptable bend -radii of 8"' for the cables.
The control lever for the cable operated rotor control valve is mounted in a similar fashion
adopting the same precautions pertaining to drilling and cable runs.
RUNNING UP PROCEDURE
CAUTION! 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 the tractor and engage the
P.T.O. Allow the oil to circulate through the return line filter for about 5 minutes without
operation of the Armhead Control Lever.
Do not leave the tractor cab or allow anyone to approach the flailhead whilst the machine is running.
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 the ‘START’ position after initial fluctuation the rotor should settle to a steady speed. Increase P.T.O. speed to
approximately 360 rpm and run for a further five minutes before disengaging and stopping
the tractor.
Check the hose runs to ensure that they are free from any pinching, chaffing, straining or
kinks.
Re-check the oil level in the tank - top up as necessary if required.
Do not allow a pump to continue working if the rotor does not turn –
Overheating and serious damage to the pump can occur in a very short time.

STORAGE OF THE MACHINE
If machine is to be left standing for an extended period of time, lightly coat the exposed
portions of the ram rods with grease. Subsequently this grease should be wiped off before
the rams are next moved.
If the machine has to be stored outside tie a piece of tarpaulin or canvas over the control
assembly, do not use a plastic fertilizer bag as this may lead to rapid corrosion of the
component.

PREPARATION
READ THE BOOK FIRST
Ensure both the Owner and the Operator of this machine has read this book in its entirety and that
they are familiar with all aspects regarding its safe use.
Operators of this machine should practice operating it in a clear safe open area, without the rotor
running, until they are fully familiar with its controls and operation.
CAUTION
Care must be taken when operating the machine with the flailhead close in, as it will come into
contact with the tractor.

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.
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.

29
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 - be alert
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.
The force required to activate the breakaway system will vary dependent upon the gradient of work.
It will require less force when working uphill and vice versa.
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 5° 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 reposition 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 the reach fully in -
IT IS POSSIBLE FOR THE FLAIL HEAD TO HIT THE TRACTOR OR MACHINE FRAME.
NOTE
NOTE
CAUTION
30
POSITIONING MACHINE FOR TRANSPORTATION
Moving into the Transport position
● Select ‘ROTOR OFF ‘ and wait until the rotor has stopped
turning.
● Ensure that ‘LIFT’ and ‘ANGLE FLOAT’ are switched off.
● Select ‘SLEW’ mode on the controls.
● Operate ‘SLEW IN’.
● Operate ‘LIFT’ and ‘REACH’ to position the
machine – see diagram opposite.
● Operate ‘REACH IN’ until the dipper arm contacts the
transport cradle.
● Select ‘LIFT UP’ and raise the arms until the tension link
is a minimum of 300mm (12”) from the tractor cab.
● Operate ‘ANGLE’ and position the flailhead in as
compact position as possible.
● Fully screw in the lift ram and slew ram taps.
31
TRANSPORT POSITION
The machine is transported in line to the rear of the tractor with a minimum of 300mm (12”)
of clearance between the tension link and the rear cross member of the tractor cab.
Transport Position with Flailhead Attached
Transport Position with Flailhead Removed
With the flailhead removed the arms of the machine 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.
During Transport the ‘Slew’ mode must ALWAYS be selected on the Control Unit.
WARNING
32
TRANSPORTING
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 all 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 installations the transport
height will generally fall between a minimum of
3.45m and a maximum of 3.65m when the
machine is correctly folded.
Overhead Obstructions
Always be aware the machine is approximately 4 metres high when folded, take care when
manoeuvring in areas with overhead obstacles especially power cables, low bridges etc. or
when entering buildings.
Moving from Transport to Work Position
Reverting to the ‘work position' is basically a reversal of the previous ‘moving into
transport’ procedure. Note - remember to unscrew the lift ram tap.
33
ROTOR OPERATION
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.
Rotor Operating Speed
Tractor Forward Speed
The material being cut determines tractor
forward speed.
Forward speed can be as fast as that
which allows the flail head sufficient time
to cut the vegetation properly.
If speed is too high it will be indicated by
over frequent operation of the breakaway
system, a fall off in tractor engine revs,
and a poor finish to the work leaving
ragged uncut tufts and poorly mulched
cuttings.
34
HEDGE CUTTING PROCEDURE
Never cut over the far side of the hedge.
It is impossible to see any potential hazards and the position of the flail head will allow the
possibility of debris being thrown through the hedge towards the tractor and operator.
WARNING
35
SAFE WORKING PRACTICES
Working on Public Highways
When working on the public highway it is the Operator’s responsibility to familiarise
themselves 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 in all areas bystanders must be kept away from the potential
danger area.
It is the operator’s responsibility to observe all safety regulations
and keep bystanders at a safe distance from a working machine.
General Working Practices
It is the Operator’s responsibility to develop safe working procedures.
ALWAYS:
▲ Be aware of hazards in the vicinity.
WARNING
▲ Make sure all guards are in position and in good condition.
▲ Disengage P.T.O. before stopping the engine.
▲ Wait until the flail has stopped running before leaving the tractor seat.
▲ Disengage the P.T.O. 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
Always inspect the work area prior to cutting to remove
hazardous material and note any immovable objects.
Working on Adverse Slopes
When working high with the 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
connection of the lift ram prevents sudden
unpredictable movements should this occur.
36
HIGH VOLTAGE CABLES
WARNING!
Depending on the voltage of the cables and the
weather conditions there is a danger of ‘electric
flashover’ if the head or arms of the machine
approach the cables too closely.
Always maintain a minimum clearance distance
of 1.5m when operating near high voltage
cables - If in any doubt consult your local
electric company regarding a safe procedure
for work in these situations.
Always be aware the machine is approximately 4 metres
high when folded, take care when manoeuvring in areas
with overhead obstacles especially power cables, low
bridges etc. or when entering buildings.
37
LIFT FLOAT KIT – Optional Extra for Ground Cutting
Fitting Location
The hydraulic float kit should be mounted to the
special bracket in such a position that it does
not foul any other component during the
slewing movement of the machine.
Power Supply
The switch can be mounted in a convenient
location within the tractor cab and the supply
cable from the poppet valve solenoid connected
into the tractor’s ignition system - the brown
lead is positive and the blue lead is negative.
38
MAINTENANCE
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
Regularly check the PTO guards for damage and ensure that the ‘anti-rotation’ chains are
in place and their anchor points are in good condition.
Do not operate the machine with damaged guards - replace suspect items immediately.
PTO Lubrication
Lubricate the PTO Shaft at the points indicated below, at the intervals stated using
general-purpose lithium based grease.
IMPORTANT: Grease new
machines before first use.
39
HYDRAULIC SYSTEM
Oil Supply
Check the oil level in the reservoir daily.
No fixed time period can be quoted for oil changes as operating conditions and
maintenance standards vary so widely. Burnt and scorched oil odours and the oil
darkening and thickening are all signs of oxidation and indicate the oil should be changed.
Moisture that results from condensation can become entrapped in the oil and cannot be
removed by filtration so water contamination is progressive.
Contamination of the oil can be reduced by:
3 Cleaning around the reservoir cap before removal, and keeping that area clean.
3 Using clean containers when replenishing the system.
3 Regular servicing of the filtration system.
Filtration Maintenance
The machine is protected by a 125-micron suction strainer and a low-pressure 10-micron
full flow return line filter.
Suction Strainer
The strainer is permanently fixed within the reservoir.
Should symptoms of pump cavitation or spongy intermittent operation occur the tank must
be drained and flushed out with a suitable cleaning agent such as clean diesel oil.
Return Line Filter
The elements should be changed after the first 50 hours of work and thereafter at 500hour intervals. It is important to note hours worked
internal by-pass within the canister will operate and no symptoms of filter malfunction will
occur to jog your memory.
PTO Gearbox
Refill with 0.5L of SAE 80 or ISO 100 at the following intervals:
● After an initial 50 hours.
● Thereafter annually or at 500-hour intervals - whichever occurs earliest.
as if the filter becomes blocked an
40
HYDRAULIC HOSES
The condition of all hoses should be carefully checked during routine service of the
machine. Hoses that have become 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
possible opportunity.
Hose Replacement
• 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.
Before changing hoses study the installation - these are carefully calculated so as to
prevent hose damage during operation. Always replace hoses in exactly the same manner
- this is especially important for the flail hoses where they must be crossed, upper to lower,
at the dipper and head pivots.
All Hydraulic Hoses (B.S.P.) 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: REF.'O' ring
1/4" BSP = 24 N.m or l8 lbf ft 10 000 01
3/8" BSP = 33 N.m or 24 lbf ft 10 000 02
1/2" BSP = 44 N.m or 35 lbf ft 10 000 03
5/8" BSP = 58 N.m or 43 lbf ft 10 000 04
3/4" BSP = 84 N.m or 62 lbf ft 10 000 05
1" BSP = 115 N.m or 85 lbf ft 10 000 06
For hose unions (B.S.P.) fitted in conjunction with bonded seals the recommended torque
settings are as follows: -
1/4" BSP = 34 N.m or 25 lbf ft
3/8" BSP = 75 N.m or 55 lbf ft
1/2" BSP = 102 N.m or 75 lbf ft
5/8" BSP = 122 N.m or 90 lbf ft
3/4" BSP = 183 N.m or 135 lbf ft
1" BSP = 203 N.m or 150 lbf ft
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.
41
CONTROL CABLES
The 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 both directions.
CAUTION
On no account should any attempt be made to lubricate the cables, which are assembled
with a special lubricant during manufacture.
NOTE
Take care to ascertain the correct cable connections on both the control unit and the valve
in the event of cable replacement.
