Necessary repairs or maintenance work is carried
out before using the hedge trimmer.
Adjusting the cutting device (Fig. 9)
Readjust the sliding clearance if material to be cut
is jammed between the cutters or the play has in-
creased due to normal wear of the cutting device af-
ter prolonged use.
In order to achieve good cutting results, the sliding
clearance between the cutting edges and the blade
must be adjusted correctly.
Proceed as follows:
1. Loosen the nuts (A) on the top of the cutting de-
vice.
2. Tighten the screws (B) on the bottom slightly
(loosen them slightly beforehand if necessary).
3. Turn the screw back by a quarter to a half turn
anti-clockwise.
4. Hold the screw with the screwdriver and tighten
the nuts tight.
The sliding clearance is adjusted correctly when
the washer beneath the screw head can be
moved back and forth a little by hand.
5. Lubricate the cutting device using environmental-
ly friendly lubricating oil.
Not enough sliding clearance results in strong
heat development and thus damage to the de-
vice.
Lubricate transmission
Lubricate the transmission every 20 operating hours.
1. Apply the grease gun to the grease nipple (10).
2. Squeeze some grease into it.
Adjusting the idle speed (Fig. 10)
If the cutting device continues to run when idle, the
idle speed must be corrected.
1. Let the motor warm up for 3-5 minutes (no high
motor speeds!).
2. Turn the set screw (C):
Clockwise
- Idle speed increases (+)
Counter clockwise
- Idle speed decreases (-)
Contact the manufacturer if the cutting device still
continues to run with the motor at idle.
Do not work with the hedge trimmer again under any
circumstances!
Cleaning or replacing the air filter (Fig. 6)
Clean the air filter of dust and dirt regularly to avoid
- starting difficulties,
- performance losses,
- too much fuel consumption.
28 | GB
Clean the air filter approx. every 8 operating hours,
more often in particularly dusty conditions.
1. Set the start lever (choke) (4) to "Cold start" so
that no particles of dirt get into the carburettor.
2. Remove the air filter cover (8).
3. Remove the air filter (D) from the foam.
4. Wash the air filter in lukewarm soapy water. Do
not blow out the particles of dirt, there is a danger
of eye injuries!
5. Clean the inside of the air filter with a brush.
6. Allow the air filter to dry and reinsert it again.
7. Attach the air filter cover again.
Replace the air filter regularly.
Damaged air filters must be replaced immediate-
ly.
Clean or replace the fuel filter
Check the fuel filter (E) if necessary. A contaminated
fuel filter hinders the fuel supply.
Open the tank cover (12) and pull the fuel filter
through the opening using a wire hook.
• Light contamination
- Remove the fuel filter from the fuel line and clean
the filter in cleaning solvent
• Heavy contamination
- Replace the fuel filter
Clean or replace the spark plug
(Fig. 2/7)
Do not touch the spark plug (F) or the spark plug con-
nector (16) while the motor is running. High voltage!
Danger of burning if motor is hot. Wear safety gloves!
Check the spark plug and the gap of the electrodes
regularly.
Proceed as follows:
1. Remove the spark plug connector from the spark
plug.
2. Unscrew the spark plug with the supplied spark
plug wrench.
The electrode gap must be 0.6 to 0.7 mm.
Clean the spark plug if it is contaminated.
Replace the spark plug:
- Once a month in the event of regularly use
- If the insulating body is damaged
- In the event of heavy electrode erosion
- In the event of heavily contaminated or oily elec-
trodes
