Replacing the spark plug

CAUTION:

Do not touch the spark plug or plug cap if the engine is

running (high voltage).

Switch o 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

very dirty or oily.

Remove the lter cover (see “Cleaning the air lter”).

Pull the plug cap (9) o the spark plug. You can remove the

plug cap by hand.

Checking the ignition spark

Press the loosened spark plug (10) with the ignition cable

rmly connected against the cylinder using insulated pliers

(not near the spark plug opening).

Put combination switch (11) in the “ON” position.

Pull the starter cable hard.

If the function is correct, an ignition spark must be visible

near the electrodes.

Checking the muer screws

Unscrew 3 screws (12) and remove the upper half of the

muer (13).

Note: For saw models with catalytic converters (EA3200S,

EA3201S), remove the converter along with the upper muf‑

er half.

The screws on the bottom muer half (14) are now

accessible, and it is possible to check them for tightness.

If they are loose, tighten by hand (Caution: do not over‑

tighten).
