GreenTec Quadsaw: LRS series
Quick start guide
Original version
This quick start guide shows and describes how to assemble a GreenTec LRS Quadsaw on a
GreenTec HXF Multi Carrier. Mounting on other multi carriers often takes place in the same way -
always use an instruction book from the multi carrier used!
Remember that the quick start guide does not replace the instruction
manual for the attachment tool or the multi carrier!
(Always read the instruction manual carefully)
The following guide shows step-by-step instructions for installing an LRS-series quadsaw, with
accompanying pictures and explanations in the following sections:

Assembly of both the HXF Multi Carrier and the LRS Quadsaw must be carried out safely and
carefully:
Make sure that the tractor and front loader can carry the multi carrier and
the attachment tool in a safe and stable way, even if it is hanging out on
the side!
The multi carrier must only be assembled on a flat and firm surface, with
good space conditions, so that the tractor and attachment tool can
maneuver freely without the risk of getting caught!

1. Unpacking of LRS Quadsaw:
•Carefully cut off the plastic. Be careful not to cut hoses, wires and not to scratch the paint.
•All loose parts for the attachment tool are packed down together with or bolted / tied to the
transport pallet.

2. Mounting of LRS Quadsaw on the Multi Carrier:
•Carefully move the lever to the mounting plate of the quadsaw.
oOptionally: use a pallet lifter to fine-tune the position of the saw.
•Fit the 4 bolts and 2 nuts and tighten them loosely on the saw.
•Before tightening, turn the entire quadsaw counter clockwise so that the top saw blades cuts
the hedge first. (See instruction manual)
•The bolts are tightened to 140 Nm.

3. Assembly of hydraulic hoses:
Pay attention to the maximum permissible
pressure, especially on the drain hose and the
return hose.
Return and drains must not be connected in the
same tank connection.

DRAIN:
•The smallest hose is for DRAIN: marked in BLUE.
•The hose is connected to a pressureless (0 bar) tank connection.
The drain hose must NOT be connected to RETURN.
Drain pressure must never exceed 2.0 bar outside the engine.
Failure to do so will damage the hydraulic motor and void the warranty.
PRESSURE:
•The middle hose is for PRINT: marked in RED.
•The hose is connected to the double-acting outlet with max. 200 bar pressure.
(There is overpressure protection in the valve block on the multi carrier)
RETURN:
•The largest hose is for RETURN: marked in GREEN.
•The hose is connected to the double-acting socket.
•Minimum pressure 5 bar (If this pressure is not achieved, a non-return valve must be fitted
o(Item no .: CA19 / 4)
•Max. back pressure 15 bar outside the engine.

4. Mounting of saw blades:
Watch out for the sharp saw blades! Avoid cuts, always wear sturdy leather
gloves!
The tractor or skid steer loader must be switched off, the parking brake
applied, and the key must not be in the ignition switch!
•Make sure that the saw shank does not touch the housing on the quadsaw. Place the blade's
dust disc on the saw shank bracket.
•Place the saw blade on the bracket so that the teeth point downwards at the front of the
quadsaw.
•Place the saw blade mounting washer on the bracket and mount 6 pcs. bolts.
•Tighten the bolts:

•Rotate the saw blade by hand, the blade should run smooth and effortlessly.
•This procedure is performed for all saw blades.

5. Installation and adjustment of branch guide and plastic
rejector:
•Dismount the 2 bolts and place the branch guide under each saw blade and finger tighten the
bolts.
•Adjust branch guides and black plastic deflector so that they come as close to the blade as
possible, without touching.
•It is important that the branch guide is as close as possible to the cutting side of the saw
blade. (See photo above)
•Tighten all bolts:

•Control: Turn the saw blades by hand, they must be able to rotate 360 degrees freely, without
touching anything.

6. Careful testing: 15 min. test drive without sawing:
Before start-up, make sure that everything is tightened, that the safeguards of the saw blades are
dismantled and that the saw blades can rotate freely 360 degrees, without touching anything.
There must be no people or animals near the saw blades, especially not in
the longitudinal direction of the blade rotation, in front of or behind the
saw!
•Start the tractor. Let it run at low RPM.
•Check the angle cylinder: Move the quadsaw from full horizontal to the full vertical position at
least 3 times to bleed the tilting cylinder.
•Start the hydraulics for the quadsaw and let the saw run at a relatively low pace.
•Allow the quadsaw to run for a while to heat up the oil.
oDepending on ambient temperature: 5-10 minutes
•When the oil is warm enough for operation, increase the RPM to ensure that the tractor
supplies at least the amount of oil (l / min) required by the LRS quadsaw.
o25-50 l / min. is required (Depending on which LRS jigsaw is used) for the saw blades
to run at max. 3200-4000 RPM.
oSee the instruction manual for the LRS Quadsaw.
If the speed is increased further, more oil is sent to the multi carrier, but
the flow regulator sends everything over the required amount back to the
tractor.
Nothing happens to the attachment tool, but the tractor's oil is supplied
with extra energy, which uses more fuel and provides extra heat in the
hydraulic oil.
•Let the saw test run for a minimum of 5 minutes. Then lower the RPM of the tractor and turn
off the oil supply so that the saw comes to a quiet stop.
•After the test run, check everything on the quadsaw. REMEMBER to carry out the same
inspection after the first day's work:
oAre there oil leaks? →Tighten hoses and fittings.
oAre all bolts tightened? →Tighten bolts.
oIs the belt for the saw blades still properly alligned? →Adjust the belt.
•The multi carrier and the LRS Quadsaw are now ready for use.
•(Always remember to use safeguards on the blades when transporting and storing!)

7. Installation of safety protection:
For safety reasons, the safety guards of the saw blades MUST always be
fitted during transport and storage, and must ONLY be removed before
starting work!
•First, the rear safety guard must be fitted and secured with 2 ring pins.
(See markings above)
•Then the front protection can be mounted and secured with another 2 ring pins
(See marking above)
oDisassembly takes place in reverse order.
8. Concluding remarks:
ALWAYS use the instruction book of the used attachment tool and multi carrier to create an overview
of installation, safety, use, adjustment, maintenance etc.
It is important that the operator is given both an instruction book for the
multi carrier, and an instruction book for the used attachment tool before
the machine is used for the first time!
It is also important that the operator fully understands the contents before
using the machine!
As our products are constantly evolving and improving, there may be changes in specifications.
If there is information that differs on the current machine, updated instructions can be found on our
homepage or by contacting GreenTec - Aftersales department.
