MAINTENANCE
Starter Unit
Use a brush to keep the cooling vents of the starter assembly free
and clean of debris (Fig. 90).
WARNING: The coil spring is under tension and
could fly apart causing serious injuries. Never try to
disassembly or modify it.
89B
Engine
Clean the cylinder & flywheel fins with compressed air or a brush
periodically (Fig. 91). Dangerous overheating of engine may occur
due to impurities on the cylinder.
WARNING: Never run the saw without all the parts,
including the drivecase cover and starting housing,
securely in place.
Because parts can fracture and pose a danger of
thrown objects, leave repairs to the flywheel and
clutch to trained Servicing Dealers.

Spark Plug
This engine uses a Champion RCJ-4 with .02" (0.5 mm) electrode
gap (Fig. 92). Use an exact replacement and replace every six
months or more frequently, if necessary.
WARNING: Never test the ignition system with
ignition wire connector removed from spark plug
or with unseated spark plug, since uncontained
sparking may cause a fire. A loose connection
between spark plug terminal and ignition wire
connector in the boot may create arcing that could

ignite combustible fumes and cause a fire.
Use only resistor type spark plugs of the approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.
