CAUTION! Do not insert the combination tool into the

spark plug hole! Make contact only with the cylinder (oth-

erwise you might damage the engine).

against the combination tool (away from the spark plug hole)

with the spark plug cap rmly on the plug.

Put combination switch (10) in the ON position.

Pull the starter cable hard.

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

the electrodes.

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 lter cover (see „Cleaning the air lter“).

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 .020" (0.5 mm).

CAUTION: Use only the following spark plugs:

NGK CMR7A-5.

Checking the mufer screws

Unscrew 3 screws (11) and remove the upper half of the muf-

er (12).

Note: For saw models with catalytic converters (EA3500F,

EA4300F), remove the converter along with the upper mufer

half.

The screws on the bottom mufer half (13) are now accessible,

and it is possible to check them for tightness. If they are loose,

tighten by hand (Caution: do not over-tighten).
