○ Unnecessary wear on the engine parts.
○ Abnormal fuel consumption.
Clean the air fi lter daily or more often if working in
exceptionally dusty areas.
Cleaning the air fi lter
Remove the air fi lter cover (41) and the air fi lter (40).
Rinse them in warm soap suds. Check that the fi lter
is dry before reassembly. An air fi lter that has been
used for some time cannot be cleaned completely.
Therefore, it must regularly be replaced with a new
one. A damaged fi lter must always be replaced.

Spark plug (Fig. 37)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting.
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter.
○ Hard running conditions (such as cold weather).
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting diffi culties. If the engine is low on power,
diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rs t. If the spar k plug is dir t y, clea n
it and check the electrode gap. Readjust if necessary.
The correct gap is 0.024” (0.6 mm). The spark plug
should be replaced after about 100 operation hours or
earlier if the electrodes are badly eroded.

In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this
machine was originally equipped with resistor spark
plug, use same type of spark plug for replacement.

Side case (Fig. 40)
Always keep the side case and drive area clean of
saw dust and debris. Periodically apply oil or grease
to this area to protect from corrosion as some trees
contain high levels of acid.
NOTE
Pull up the front hand guard towards you and
release the brake to remove or install the side case.
