MAINTENANCE
Oil Filter
Remove the spark plug first, then the oil filter can be removed
together. Clean the oil filter periodically and replace it if necessary
(Fig.88).
CAUTION - Never use scavenge oil.
Starter Unit
88
Use a brush to keep the cooling vents of the starter assembly free
and clean of debris (Fig. 89).
WARNING: The coil spring is under tension and
could fly apart causing serious injuries. Never try to
disassembly or modify it.
Engine
Clean the cylinder & flywheel fins with compressed air or a brush
periodically (Fig. 90). Dangerous overheating of engine may occur
due to impurities on the cylinder.
89
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-8Y with .02" (0.5 mm) electrode
gap (Fig. 91). Use an exact replacement and replace every six
90
months or more frequently, if necessary.
WARNING: Never test the ignition system with ignition
wire connector removed from spark plug or with unsea-
ted 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;
91
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.
Spark Arresting Muffler
The chainsaw is provided with a Spark Arrester System p.n.
50030382 (Fig. 92) complying with the requirements of SAE J335
standard; you can check the p.n. of the Spark Arrester System on
the muffler itself.
WARNING: A faulty or altered spark arrester system
screen can create a fire hazard.
