Product Description
The Hedge cutter primarily consists of a non-movable lower knife and a movable upper
knife that both are made from Hardox steel and driven by an hydraulic ram. The
double-effect cylinder is controlled by a reversing valve that is operated over a
suspended bottom adjustment. The suspended bottom adjustments are directly
connected to the ramrod, thereby allowing the smooth rotation of the cutting direction.
The basic tool is mounted using a mounting arm with high pressure hydraulic hoses
The knife guard may be mounted on the Hedge cutter using the extension spring.
Specifications
Hedge cutter for mounting on hydraulically driven Armmowers.
Consists of two Hardox cuttings edges that are hydraulically driven over a flow divider,
two-way valve and hydraulic ram. The cutting edges are operated via external oil
supply from the hydraulically driven vehicle.
The Hedge cutter may be fitted with an adapter to facilitate mounting on various
vehicles.
The hydraulic system is completely covered.

Prior to start-up of work
Setting of Working Posture
Remove any transport protection and swing the arm into working posture.
Start the tool with a low oil flow (low RPMs / low oil flow).
Adjust the HX 170 - 230 to vertical hedge cutting and raise it to the working
posture.
Starting the Tool
Select low engine RPMs
Ensure that the area around the tool is secured.
Warm start –Start the tool.
Cold start –Never start with max. oil flow. Allow the tool to run without too
much load for about 15 min. to heat up the oil.
Slowly increase the amount of oil until the relevant speed has been achieved.
Never attempt to restart a loaded tool. Remove whatever is stuck before
restarting the tool.
Stopping the Tool
Reduce the engine RPM to fast idling. Stop the tool.
Never quickly increase or reduce the amount of oil as this may damage the
hydraulic system in the long term.
Place the tool on the ground when taking a break.
Driving Instructions
We recommend that you drive slowly at first and pay attention to the terrain and
whether the hedge is free from fencing wire, steel poles and other foreign objects.
Adjust the cutting angle to a position approx. 90 degrees relative to the branches. In
case of large branches, adjust the cutting height to the center of the cutting opening.
Never drive too fast to allow clean cutting.
Low speeds = Nice cuts, nothing sticks out.
High speeds = Frayed cuts, twigs sticking out.

High-Voltage Cables
Mounting / Dismounting
Turn the arm system to a position next to the HX 170 - 230
Mount the bolts or snap the Quickshift (optional) together
Mount the hydraulic hoses
Lift the tool free
Dismount the knife guard
Test the function Count the strokes (optional) 60 double strokes per minute (45 - 50
L/min.)
Always pay attention to overhead cables. You may
hit the overhead cables between the power poles.
When in doubt - contact the local power plant and
inquire about the safety distance

GreenTec

Field of Application
The tool is designed for cutting hedges and branches with a max. diameter of 100mm
without fraying the branches. Branches over 70mm in diameter should be cut
individually.
Vertical cutting is allowed up to a 45 degree angle. Horizontal cutting is possible on
hedges with a max. width of 1m and a branch thickness of max. 40mm. In case of
larger branches, the cutting edges may stop and get stuck in the machine.

Maintenance
Service Check / Re-tightening
Re-tighten everything after 2 hours of operation. Pay special attention to hydraulics
and cutting edges.
Re-tighten everything after 10 hours of operation.
Re-tighten / check all bolts every 8 hours.
Dismount the hydraulic system protective cover and remove twigs and dirt from the
housing.
Following service, remount all shields, guards and protective plates.
Check the spring stop bolt tension. Adjust to 52 mm. See Illustration 2.
Illustration 2.
Lubrication
Lubricate the machine every 8 operating hours. Use more lubrication when working in
a particularly demanding environment.
Following cleaning:
Lubricate all machine parts and auxiliary equipment each time the machine has been
cleaned.
Hydraulic Hoses
Carefully check the condition of all hoses regularly. Ensure that hoses are not rubbing
against machine edges, bolts or similar.
Check the condition of all hydraulic hoses and fittings daily. Immediately correct any
and all damaged or leaking parts. This is part of the daily maintenance routine and it is
your responsibility to ensure that the machine will have a long service life.
Replace hoses with broken metal bands.
The hydraulic system uses a very high pressure. Always use original hoses. Ruptured
hoses may be lethal.

GreenTec
Hedge Cutter HX 230
18
Avoid twisting the fittings when replacing a hose. Use two single-head wrenches to
loosen and tighten hoses etc. Hoses will be impaired if they are twisted during
installation. Pressure pulses in twisted hoses tend to stress the steel net of the hose.
See Illustration 1.
Always ensure that protective hoses are in good condition. It is cheaper to replace a
protective hose than to replace valuable hoses.
Illustration 1.
The warranty on the hoses covers only the replacement of hoses due to defective
materials or manufacturing defects. The warranty does not cover the following:
1. Hoses that are damaged due to rubbing
2. Wear and tear
3. Hoses that have been cut or crushed during operation
4. Damage to threads due to excessive tightening

Oil Supply
Check the oil level in the tank every day prior to start-up.
It is good practice to constantly check the oil level gauge as a ruptured oil hose may
empty the tank in a few minutes.
A pump or motor that runs out of oil will be damaged beyond repair.
Change the oil if it appears contaminated (discolored).
Oil replenishment precautions:
- Carefully clean the area around the filler neck before removal.
- Use a clean container when refilling the system.
- Check the filter system regularly.
- Never allow the oil level to fall below the liquid indicator.

GreenTec
Hedge Cutter HX 230

Check daily that the hydraulic connections and fittings are in good condition.
Immediately correct any and all defects or leaks. It is a part of the day-to-day
maintenance that will reduce the expenses and extend the service life of the machine.
Use two single-head wrenches for tightening fittings. Avoid excessive tightening.
Change any and all fittings that keep leaking.

Storage
Carefully clean the machine before placing it in storage. Remove all traces of wood
chips and dirt. Dirt attracts moisture and results in corrosion. Be careful. Never use
high-pressure watercleaner close to the finish. Be very careful with steam cleaning.
Rinse off all cleaning agents to prevent discoloration or damage to the finish. Grease
all greasepoint until fresh grease emerges. The machine must be stored under covers
or indoors to protect it from rain and sunlight. Place the machine on a level surface.
Remember that regular maintenance greatly extends the service
life of the machine.
Caution!
Before attempting to repair, maintain or adjust the
machine, check that the knife has stopped, the ignition key
is removed, the PTO disengaged, the parking brake
engaged and that the head rests safely on the ground.
