Replacing the spark plug
CAUTION:
Do not touch the spark plug or plug cap if the engine is
running (high voltage).
Switch off the engine before starting any maintenance
work.
A hot engine can cause burns. Wear protective gloves!
The spark plug must be replaced in case of damage to the
insulator, electrode erosion (burn) or if the electrodes are very
dirty or oily.
Turn the cover lock (6) to the ”Unlocked ” position and
carefully remove the filter cover (7).
Pull the plug cap (8) off the spark plug. Use only the combination
wrench supplied with the saw to remove the spark plug.
Electrode gap
The electrode gap must be 0.5 mm (.020").

Foam prefilter and inner filter
IMPORTANT:
Do not use fuel to clean the foam prefilter and inner filter!
If the foam prefilter (1) and inner filter (2) are dirty, wash them
with dishwashing liquid in lukewarm water.
Dry thoroughly!
NOTE:
Under very dusty conditions it will be necessary to clean the
foam prefilter daily. If this is not possible on-site, have a
sufficient supply of reserve foam prefilters on hand.
When placing the foam prefilter in the filter cover position it with
the angled corner (3) against the angled corner in the inside of
the cover (4) and press into the filter cover.
Paper cartridge
The paper cartridge (5) filters the intake air through a very fine
paper filter laminate system. For this reason it must never be
washed.
Clean paper cartridge every week.
Spread the paper filter a little and tap it out on a clean surface.
Replace the cartridge periodically, and especially in case of
poor performance, reduced engine speed, or smoky exhaust.
Before reassembling the filter system, check the intake open-
ing for dirt particles, and remove any found.
CAUTION:
If the air filter becomes damaged, replace immediately!
Pieces of cloth or large dirt particles can destroy the
engine!
