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 (See drawing) using
the hooks provided. Shape the mesh to cover
all vulnerable areas. The driver must be
looking through mesh and/or polycarbonate
glazing when viewing the working tool 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 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.

Side 10 af 27
Factors that affect 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 Chlo-
ride 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).
NOTE: The advice above is offered as a guide for stability only and is not a guide to vehicle strength. It is recom-
mended that you consult your vehicle manufacturer or local dealer to obtain specific advice on this subject, addi-
tionally 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.

Mounting the Quadsaw
The blades MUST be mounted in a downward cut rotation. Mount the blades so they are cutting
down (Must run same way as the tractor) (Fig. 1).
Mount the Quadsaw so the blades are running in the driving direction (Fig. 2).
Mount the hydraulic hoses so the blades are running in correct direction. Separate drainage hose
(max 1,5 bar) must be led directly to the oil reservoir.
Also separate, the Return hose must be led directly to the oil reservoir (max 15 bar)
Check for oil leak.
First time the machine is used. Measure the blade rpm. LRS 2001 and 2401 (3000 –3200 rpm).
Holding this speed is important for the best optimum performance.
Never use the machine with broken or missing sawblades.
Blades must be mounted in a downward cutting rotation only.
Fig. 1 Blade rotation Fig. 2 Driving direction

Side 12 af 27
Attachment of the machine must be performed in a safe location on a firm level site.
Care should be adopted at all times when handling or manoeuvring the machine during the
attachment procedure; ensure all persons remain clear of the cutting blades which possess the
potential to cause injury even when stationary. For reasons of safety the blade guard should be
fitted to machine at all times and only removed for machine operation.
Never use the machine on a vehicle that is unstable or unsuitable.
Attachment to Armsystem or Mounting Carrige
Can be attached to Arm-system with a clamp bracket. Nuts should be torqued 200 Nm.
Spearhead Twiga & GreenTec HXF 2802, 3300 & 3302 are all specially designed to carry the Quad-
saw.
The HXF is a mounting carriage designed for attaching Quadsaws to Tractor loaders and Tele-
handlers. features a reach of approximately 2,0-
2.5 metres, 180° manual folding system, and
hydraulic collision safety. The overall weight of
the unit, without tools, is 180-225kg. If neces-
sary, suitable ballasting should be fitted to the
vehicle to ensure the unit remains stable and
balanced in all working positions under all con-
ditions.
The Spearhead Twiga system features a reach of
approximately 4,5-9,0 metres, hydraulic folding
system, and hydraulic collision safety. The over-
all weight of the unit, without tools, is 1100-
1750 kg. If necessary, suitable ballasting should
be fitted to the vehicle to ensure the unit remains stable and balanced in all working positions under
all conditions.
1. Drive up to the machine, tilt attach
ment bracket into the horizontal
position.
2. Locate attachment bar into hooks
and secure latches.
3. Tilt bracket backwards 900.
4. Detach supporting legs (only some
models)

Operation / Introduction
The Quadsaw is used for cutting branches and trees up to a max. diameter of (LRS 2001 120 mm).
(LRS 2401 160 mm). Branches thicker than (LRS 2001 80 mm) (LRS 2401 120 mm) must be cut one
of the time.
Vertical cutting is allowed up to a 45 degree angle. Horizontal cutting is possible on hedges with a
width up to 1.2 m and a branch diameter up to 40 mm. thicker branches might stop the blades and get
stuck in the machine.
It is recommended that forward speed is kept to a minimum when starting work in order to retain the
correct working speed of the blades. Set the angle of the Quadsaw so it is positioned at right angles to
the work and adjust the machine position so the branches meet the saw blades ‘straight on’.
Wherever possible try to keep the blades running vertical in relation to the direction of travel,
this will help prevent them from ‘distorting’ during operations.
Should small branches, debris or unwanted material get stuck in the blades the machine and tractor
must be switched off and the starting key removed before attempting to clear the blockage. If neces-
sary, remove the belt cover to gain better access to the blockage; replace cover immediately before
starting or using the machine.
Never run the machine without beltcover mounted.
Fig. 1
Fig. 2

Side 14 af 27
Great care must taken when attempting to clear debris from the blade
and/or belt area of the machine; sharp components and numerous pinch
risk points exist in these locations. Safety gloves and safety eyewear
should be worn and wherever possible the use a suitable tool should be
used to remove any debris to ensure hands and fingers are kept clear of
any risk areas.
Never use the machine as a stationary saw for making firewood.
Never use the machine as a crane.
When in charge of the machine always obey the following rules;
Always inspect the work area prior to operation and remove any dangerous materials.
Never operate the machine with persons or animals in close proximity.
Ensure all cab guarding is in place and the tractor windows are kept shut.
Only operate the machine at the correct blade speed.
Never transport the machine without the blade protection guards fitted.
Never approach the machine when it is running, always switch it off and stop the tractor.
Always remove the vehicle ignition key before leaving the cab.
Never use the machine to perform tasks it was not designed for.
Always lower the machine to rest on the ground with blade protection guards fitted when
the unit is parked up or not in use.

Side 15 af 27
Driving recommendations
It is recommended to travel at a slow forward speed when starting work in order to obtain and keep
the recommended rpm of the blades. Adjust the angle of the saw to approx 90 degrees in relation to
the branches. If a thick branch is approaching the branch reflectors, the working height must be ad-
justed for the branch to hit the saw blades straight on.
If small branches or other unwanted material get stuck in the blades, the machine must be stopped
and cleaned.
Always ensure that the blades are running vertical related to the direction of the travel. This will pre-
vent the blades from bending too much.
It might be an advantage to mount a skid at the bottom of the Quadsaw to pre-
vent the saw blades from hitting the ground. (Optional equipment)
The cutting angle is as std. a “top-link”, and can only be adjusted when the machine is stopped.
A hydraulically ram (option), can be mounted. Operate the ram in the required
direction to set the desired cutting angle before starting work. The ram may be
operated during work to make minor angling adjustments, but it is recommended to stop work before
making major adjustments to the cutting angle.
To prevent sawblades in blocking there is mounted a Branchcarrier part no.
200112.0, a Plastic-strip part no. 200110.0 in the full length of the machine
and wearplates part no. 200153.0 under each sawblade to prevent sawblades bending. If the saw-
blades anyway blocks, then stop the saw, stop the carrier, take out the ignitionkey, pull the hand-
brake, take your safety goggles and gloves on and remove the jammed piece of wood.

Side 16 af 27
Maintenance
Beware of blades and belt areas when maintaining and servicing.
After 2 hours work all Taper-lock must be retightened to 31 Nm.
After 10 hours work all bolts, screws and Taper-lock bushes must be retightened. If the bushes
loosen at a later time they may be secured with Locktite.
All bolts must be retightened on a regular basis.
Year 2001-2011: The plastic strips are adjusted down to 1 mm clearance from the blades. The
plastic strips must be replaced if this exceeds 5 mm. The branch deflectors must be adjusted as
close as possible to the blades without touching.
Year 2011 and forward: The plastic strip on LRS 2401should be in line to the body.
Dismount the belt guard to clean the housing.
Inspect and if necessary adjust the belts. (See belt diagram here or under belt guard).
GreenTec A/S recommend changing all sawblade-axles after 1500 hours of work, because of the
possibility of metal fatigue.
After inspection or service ALL protection plates and guards must be replaced.
GreenTec A/S recommend changing all sawblade-axles after 1500 hours of
work, because of the possibility of metal fatigue.
Lubrication
Grease the lubrication points on machine on the following basis;
Daily prior to use.
Always prior to storage.
Always after it has been washed.
Never use grease that contains Molybdenum Disulfide on nylon bushes.
Hydraulic Hoses
Inspect hydraulic hoses and fittings on a daily basis prior to using the machine; ensure they
are free from damage or leaks and that the hoses are not rubbing on machine components.
Any damaged hoses or fittings should be repaired or replaced immediately.
Run new hoses alongside the old ones prior to removal to ensure the correct routing is
retained. When replacing a hose avoid twisting it, use 2 spanners to tighten it.
Ensure hoses bend with machine movements and that they do not twist or strain.
All hose connections are of a ‘soft seal’ type and should only be turned a further 1/2 turn
more than hand tight in order to be leak-proof (see table below).

Oil Supply
Check oil level in the tank each day prior to starting work - it is good practice to constantly
keep an eye on the sight glass level as a ruptured pipeline can empty a system within
minutes; a pump or motor that runs out of oil will be damaged beyond repair very quickly.
The oil must be changed if there are signs that it is contaminated (discolored).
Ensure cleanliness when replacing or topping up the oil by;
Carefully cleaning around the filler neck prior to opening.
Always using clean containers for refilling the system.
Regular inspection of the filtration system.
Never letting the oil level fall below the level in the sight glass.
Check daily for all hydraulic connections and fittings are in good condition. Any defect or leak
must be immediately repaired, it is part of the daily maintenance that will reduce costs and
prolong machine life.
If fittings require retightening always use 2 spanners and avoid over tightening. If the fitting
continues to leak, replace it.

Side 18 af 27
Regular Maintenance Tasks
After every 4 hours of use the following maintenance task should be observed;
Check bolts for tightness and –retighten if required.
Check valve block, hoses and fittings for signs of leaks –retighten or replace seals if
required.
Bolts and bushes should be greased and retightened.
Regrinding
If sawblades are send to regrinding, GreenTec offers a wooden box made for that purpose. can con-
tain four sawblades.

Side 19 af 27
Tensioning the Belts
Great care must be adopted when servicing the machine as there is
risk of trapping hands or fingers in the belts, pulleys or sawblades.
It is utmost importance that the belts are correctly mounted and tightened. When new belts are
mounted they must be tensioned to (LRS 2001 700 Nm) (LRS 2401 1100 Nm) for the short and (LRS
2001 900 Nm) (LRS 2401 1300 Nm) for the long belts.
After 3-5 working hours the belts may have slackened and must be checked.
The tension has now changed to (LRS 2001 550 Nm) (LRS 2401 900 Nm) for
the short and (LRS 2001 650 Nm) (LRS 2401 1100 Nm) for the long belts.
Take the lid off.
Check the Nm setting with tool 200155.0
Adjust powerbelts if required.
Re-check again with tool 200155.0
Remount the lid.
Contact GreenTec A/S After Sales Department if you have any questions. We might help you with a
piece of good advice.
