Maintenance specifically for
2-stroke device
Maintaining the engine
Danger!
If the speed of rotation is set too
high, objects 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
electromagnetic 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
Danger!
Cleaning agents pose a fire and
explosion hazard.
Never clean the air filter with flam-
mable solvents.
Caution!
A cleaning of the air filter with com-
pressed air damages the filter fabric
and the air filter becomes useless.
Change the air filter when it is dirty.
Caution!
When you use air filters from ac-
cessory 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.
