Air filter maintenance (fig. 4 + 5)
m DANGER!
Risk of fire and explosion!
If not cleaned correctly, fuel may ignite and even
explode. This can lead to severe burns or death.
- Clean the air filter only by knocking out or blow-
ing out with compressed air.
- Never clean the air filter with petrol or flammable
solvents.
-
NOTE!
Risk of damage!
Operating the engine without the filter element in
place can cause engine damage.
- Never run the engine without the air filter element
in place.
A fouled air filter insert (7b) diminishes the engine
output due to reduced air supply to the carburettor.
Regular inspection is therefore essential.
The air filter should be checked every 10 operating
hours and cleaned as required.
1.
Unscrew the wing nut (7a) and remove the air
filter cover (7).
2.
Check the air filter cover (7) for holes or cracks.
Replace any damaged insert.
3.
Remove the air filter insert (7b).

4.
Wipe off dirt on the inside of the filter housing
with a clean moist cloth. Make sure that no di-
rect enters the opening.
5.
Set the air filter cover (7) on the filter housing for
the duration of the filter cleaning process.
6.
Blow out the air filter insert (7b) from the inside to
the outside with compressed air. Do not rub dirt off
the air filter insert (7b). This can result in damage.
7.
Reinsert the clean air filter insert (7b).
8.
Put on the air filter cover (7) and secure it with
the wing nut (7a).
m ATTENTION: Never run the engine without an air
filter insert or with a damaged air filter insert. This
would allow dirt to enter the engine, which would
damage the engine. The manufacturer warranty is
then invalidated.
13.2 Cleaning / replacing the spark plug
(Fig. 6 + 7)
m ATTENTION: Only replace the spark plug when
the engine is cold!
Check the spark plug for dirt for the first time after
20 operating hours and clean it with a copper wire
brush if necessary.
Thereafter, replace the spark plug every 100 operat-
ing hours or if necessary.
1.
Disconnect the spark plug cable and remove
any dirt in the spark plug area.
2.
Unscrew the spark plug (8a) with the supplied
spark plug wrench (A) and check this.
3.
Check the insulation. Replace the spark plug
(8a) if it is damaged, e.g. cracked or fragmented.
4.
Clean the spark plug electrodes with a wire
brush.
5.
Check the electrode gap and adjust it using a
feeler gauge. To make sure that the engine re-
mains efficient, the spark plug (8a) must have
the right electrode gap (0.7 - 0.8 mm).
6.
Screw the spark plug (8a) back in by hand and
tighten it about 1/4 turn with the spark plug
wrench (A).
7.
Fit the spark plug cable onto the spark plug (8a).
m ATTENTION!
A loose spark plug can overheat and cause damage
to the engine. If you tighten the spark plug too much,
the thread in the cylinder head may be damaged.
