Maintenance

In order to aviod possible injuries wear gloves.
To guarantee a long and reliable usage of the hedge trimmer
carry out the following maintainance works regularly.
Check the hedge trimmer for obvious defects such as
− loose fastening elements
− worn or damaged components
deformed, broken or damaged cutting device
−
− leaks from the fuel tank cap or fuel lines
Check the hedge trimmer after each application for
wear and tear, in particular sliding play of the cutting device
−
− correct assembly and faultless covers and protective
devices.
Necessary repair or maintainance operations have to be carried
out before the usage of the hedge trimmer.

Adjusting the cutting device

Readjust the sliding play if cut material is clamped between the
blades or the play has increased due to normal wearing of the
cutting device after a longer period of use.
To obtain good cutting results the free motion between the
blades and the sword must be correctly adjusted.
For this proceed as follows:
1. Loosen the nuts (A) on the top surface of the cutting device.
2. Slightly tighten the screws (B) on the underside (if required
loosen them previously).
3. Turn the screw back anticlockwisely by a quarter up to a half
turn.
4. Use a screwdriver to hold the screw and firmly tighten the
nuts.
The sliding play is correctly adjusted if the washer
under the screw head can just be freely moved back
and forth by hand.
5. Lubricate the cutting device using environmental-compatible
lubricating oil.
If the play is too small, this may cause a great extent of
heating and thus damage to the device.

Lubricating the gearbox

Lubricate the gearbox every 25 operating hours.
1.
Put the grease gun onto the grease filling plug (25). The
grease filling plug is located at the gearbox (on the bottom of
the hedge trimmer).
2. Force some grease into the zerk fitting.
Do not fully fill the gearbox. Grease expands due to heat
generated during operation There is the risk of damages to
seals and grease leakage when the gearbox is fully filled
with grease.
Use SHELL ALVANIA RL3, for example, or an equivalent
grease brand.

Adjusting the idle speed

The carburetor is factory-set to the correct idle speed so that the
correct fuel-air mixture is fed to the engine.
The idle speed is correcly adjusted when the engine runs
smootly in every position. It should be a clear difference to
the speed at which the cutting device begins to move. Also
the cutting device may not move when the choke is put to
.
In the cases below the carburetor (idle speed) has to be
corrected:
− The cutting device continues to move at idle speed (idle
speed too high).
− Erratic running or lack of acceleration (idle speed too low)
− Adjustment to weather conditions and temperatures
An incorrect carburetor adjustment results in severe
engine damages. Do not continue working with the
machine in such a condition.
Do not continue working with the hedge trimmer in
such a condition.
Cleaning / replacing the air filter
Clean the air filter from dust and dirt on a regular basis to
prevent
− starting problems,
carburetor faults,
−
− loss of output,
worn engine parts
−
− too high fuel consumption.
Clean the air filter every 25 operating hours, or more frequently
in dusty environments.
1. Put the choke (22) to
coming into the carburettor.
2.
Remove the air filter cover (20).
3. Remove the air filter (23).
4. Wash the air filter in a luke warm soapy solution.
Do not blow out dirt particles, otherwise there is a risk
of eye injury.
5. Clean the air filter interior using a brush.
6. Allow the air filter to dry well and reinsert it.
7. Re-mount the air filter cover.
Never operate the machine without air filter. Dust and dirt
can enter the engine and cause damages to the machine.
Replace the air filter on a regular basis.
Damaged air filters must be replaced without delay.

Cleaning/replacing the fuel filter

Check the fuel filter (9) if required. A contaminated fuel filter
restricts the fuel supply.
