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 .023” (0.6 mm).
CAUTION: Use only the following spark plugs: NGK CMR6A.
Checking the ignition spark
Press the loosened spark plug (9) with the ignition cable
rmly connected against the cylinder using insulated pliers
(not near the spark plug opening).
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.
Checking the mufer screws
Unscrew 3 screws (11) and remove the upper half of the
mufer (12).
Note: For saw models with catalytic converters (EA3500S,
EA3501S), remove the converter along with the upper mufer
half.
The screws on the bottom mufer 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).
