Replacing the spark plug
Electrode gap
The electrode gap must be .020"-.030" (0,5 - 0,8 mm).
Checking the ignition spark
- Press the loosened spark plug with the firmly connected
ignition cable against the cylinder by means of insulated
pliers (not near the spark plug opening).
- ON/OFF switch in START position "I".
- Start the engine by forcefully pulling out the starter cable.
If the function is correct, an ignition spark must be visible near
the electrodes.
- Demount the filter cover (A/1) (2 screws).
Caution: Pull the choke (A/2) to shut the choke shutter and
to prevent dirt particles from entering the carburetor.
- Loosen the two screws (A/4) and remove the air filter (A/3)
from the intake stack.
- Position a screw driver between the two latches and se-
parate the upper and lower part by turning it.
- Clean the air filter with a soft brush.
- If the filter is very dirty, clean it in lukewarm soapsuds with
standard detergent.
- Let the air filter dry completely.
- Assemble the upper and lower part and put them on the
intake stack. Firmly tighten the screws (A/4).
If the filter is very dirty, clean it frequently (several times a day),
because only a clean air filter guarantees full engine power.
CAUTION:
Replace damaged air filters immediately.
Torn off pieces of cloth may destruct the engine.

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 a damage of the
insulating body, consumption of the electrodes or if the elctro-
des are very dirty or oily.
- Loosen both screws of the filter cover (A/1) and remove
the filter cover (see fig. clean air filter).
- Pull off the plug cap (C/3) from the spark plug. Only use the
universal wrench delivered with the chain saw for demoun-
ting.
- Mount the new spark plug in the reverse order.
CAUTION: Use only the following spark plugs:
- NGK BPMR 7A or BOSCH WSR 6F.
0,5 - 0,8 mm
.020" - .030"
