Maintaining the engine
Warning
If the speed of rotation is set too high, ob-
jects can be ejected. The engine can be
damaged and noise pollution increases.
► Do not change the basic setting of the
carburetor or the speed control.
To ensure a long service life of the engine, suf-
ficient engine cooling is required.
Keep the
- engine cover (ventilation grid),
- silencer (protective grid) and
- cooling fins of the engine
clean at all times.
Checking the spark plugs
Danger
The ignition system generates an electro-
magnetic field.
► Wearers of pacemakers must not work
on live parts.
Soiled spark plugs reduce the engine output.
Clean the electrode of the spark plug with a
brass wire brush. Check the electrode gap
(see “Technical data”). Make sure that the in-
sulator around the electrode is not damaged.
Never use a damaged spark plug.
Tighten the spark plug with the torque indic-
ated in the technical data.
Maintaining the air filter
Warning
Cleaning agents pose a fire and explosion
hazard.
► Never clean the air filter with flammable
solvents.
Notice
A cleaning of the air filter with compressed
air damages the filter fabric and the air filter
becomes useless.
► Change the air filter when it is dirty.
Notice
When you use air filters from accessory
suppliers, the engine can be damaged.
► Only use the original AS-Motor air filter
cartridges.
Beware!
During filter change, accumulated dirt
in the air filter can get into the carburetor and
damage it.
1. Screw off the air filter cap.
2. Carefully pull out the filter element. Make
sure that no dirt from the inside of the air fil-
ter housing enters the carburetor.
3. Close the suction opening with a clean
cloth.
4. Thoroughly clean the inside of the air filter
housing.
5. Remove rough, loose dirt from the filter ele-
ment by tapping. Replace the filter element
in case of heavy, stubborn dirt.
6. Remove the cloth of the suction opening.
7. Re-insert the filter element.
8. Close the air filter cap again.
