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.
Pull the plug cap (1) off the spark plug. Use only the combina-
tion wrench supplied with the saw to remove the spark plug.
CAUTION: Use only the following spark plugs:
NGK BMR 6A or CHAMPION RCJ 8.

Electrode gap
The electrode gap must be .020" (0.5 mm).
Checking the ignition spark
Press the loosened spark plug with the ignition cable firmly
connected against the cylinder using insulated pliers (not near
the spark plug opening).
Press the short-circuit switch forward.
Pull the starter cable hard.
If the function is correct, an ignition spark must be visible near
the electrodes.

Remove the filter cover (see ”Cleaning the air filter”).
Unscrew four screws (2). Remove fan housing (3).
Remove all pieces of cable.
Unscrew the screw (4) and remove the washer.
Carefully pull off the cord drum.
Thread in a new cable (1/8" dia. x 35" long) as shown in
Figure B and tie the ends as shown.
Pull knot (5) into the cable pulley (6).
Pull knot (7) into the cable grip (8).
Put the cord drum back on and turn gently until the return spring
catches.
Wind the cord clockwise around the drum. Then use the
starting handle to pull the cord from the drum, hold the drum
still and wind the cord around it again.
CAUTION: Danger of injury! Secure the cable grip when
pulled out! It will whip back if the cable pulley is released
by accident.
NOTE: With the cable pulled all the way out, it must still be
possible to turn the pulley another 1/4 turn against the return
spring.
When replaceing fan housing, it may be necessary to pull the
starter cable lightly so that the cable pulley catches.
