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 (3000 –3200 rpm).
LRS 2401 (2700 –2800 rpm).
Holding this speed is important for the best optimum performance.

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.
Maintenance
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 recommend changing all 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.
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 prevent the saw blades
from hitting the ground. (Optional equipment)

Belt diagram
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.
BEWARE!! 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.
Contact GreenTec A/S After Sales Department if you have any questions. We might help you with a
piece of good advice.

Safety
Newer operate the machine with other people present, as it is possible for debris to be thrown
from the saw blades in all directions.
Always ensure all cab safety guards are in place and all tractor windows are closed. Newer al-
low an inexperienced person to operate the machine without supervision.
Newer allow children to play o nor around the machine at any time.
Newer attempt any maintenance or adjustment without first disengaging the
pto/hydraulicpump, lowering the head to the ground, stopping the tractor engine and applying
the tractor parking brake.
Before leaving the cab remove the ignition key.
Newer stop the engine with the pto engaged.
Before leaving the tractor cab always ensure that the saw head is firmly on the ground, no
weight is on the tractors hydraulics and blades have stopped spinning.
Newer transport with the pto engaged.
Always check that all guards are properly fitted, check there are no damaged or loose parts.
Always operate the blades at a speed between 2700-3200 rpm (depending on model).
Maximum oil pressure of 250 bar in the hydraulic hoses.
Newer transport without the blade protection guards mounted.
Always inspect work area for wire, steel posts, large stones and other dangerous materials. If
such items are found remove them.
Newer attempt to use the machine for any purpose other than that it was designed for.
Ensure that all warning labels are always visible and that they are not damaged, defaced or
missing.

Noise measuring
Noise measuring has been made on the machine during normal working conditions at GreenTec A/S,
Denmark, with a Delta OHM Noise measurer, type HD 8701.
The energy A-weighted Sound pressure is lower than: 90 dB (A).
The test has been done in a distance of 1 meter from the machines critical noise maker and in a height
of 1,5 m over the ground.
