Replacing The Spark Plug; Replacing The Suction Head - Makita EK8100 Operator's And Safety Manual

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.
Remove the filter cover and hood. See Cleaning / changing
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.
CAUTION: To prevent damage to the decompression valve
(8), when unscrewing the spark plug position the combi-
nation tool in such a way that it does not impact the valve.
Electrode gap
The electrode gap must be .020" (0.5 mm).
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 opening.
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!
