checking the ignition spark
Insert the combination tool (9) between the ventilation hood and
cylinder only as shown in the illustration.
cAUTION!
Do not insert the combination tool into the spark plug hole,
but make contact only with the cylinder (otherwise you may
damage the engine).
Using insulated pliers, hold the spark plug (10) (unscrewed but
with the plug cap on) against the combination tool (away from
the spark plug hole!).
Switch the combination switch (11) to ”I”.
Pull the starter cable hard.
If the function is correct, an ignition spark must be visible near
the electrodes.
Replacing the suction head
The felt filter (13) of the suction head can become clogged.
It is recommended to replace the suction head once every
three months in order to ensure unimpeded fuel flow to the
carburetor.
Unscrew the tank cap (12), pull the retainer out of the open-
ing.
Empty fuel tank.
Use a wire hook to pull the suction out of the tank opening for
replacement.
caution: Do not allow fuel to come into contact with skin!
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 (Order No. 965 603 021) must be replaced in
case of damage to the insulator, electrode erosion (burn) or if
the electrodes are very dirty or oily.

the air filter.
Pull the plug cap (7) off the spark plug. Use only the combination
wrench supplied with the saw to remove the spark plug.

(8), when unscrewing the spark plug position the combina-
tion tool in such a way that it does not impact the valve.
