13.3 Air filter maintenance (20) (Fig. 1)
m DANGER!
Risk of fire and explosion!

plode. This can lead to severe burns or death.

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 diminishes the engine output
due to reduced air supply to the carburettor. Regular
inspection is therefore essential.
The air filter should be checked every 50 operating
hours and cleaned as required.
1.
Open the wing nut (20a) of the air filter cover (20)
to open it.
2.
Check the air filter cover (20) for holes or cracks.
Replace any damaged insert.
3.
Wipe off dirt on the inside of the filter housing with
a clean moist cloth. Make sure that no direct enters
the opening.
4.
Remove the filter element. Check it for damage
and replace it if necessary.
5.
Blow out the filter element thoroughly with com-
pressed air.
6.
Top up the oil in the air filter housing if necessary.
(see 10.3).
7.
Reinsert the clean filter element and screw the air
filter cover (20) with the wing nut (20a).
13.4 Clean/replace the spark plug
m ATTENTION!
Only replace the spark plug when the engine is cold!
Check the spark plug for contamination for the first time
after 10 operating hours and clean it with a copper wire
brush if necessary.
Thereafter, replace the spark plug every 100 operating
hours or if necessary.
1.
Disconnect the spark plug connector and remove
any dirt in the spark plug area.
2.
Unscrew the spark plug with the supplied spark
plug wrench (C) and check it.
3.
Check the insulation. Replace the spark plug if it is
damaged, e.g. cracked or fragmented.
4.
Clean the spark plug electrodes with a wire brush.
