Spark plug (Fig. 36)
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 rst. If the spark plug is dirty, clean 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.

NOTE
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.

Guide bar (Fig. 38)
Before using the machine, clean the groove and oiler
port (42) in the bar with the special gauge off ered as an
optional accessory.
Side case (Fig. 39)
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.
Fuel fi lter (Fig. 40)
Remove the fuel fi lter from the fuel tank and thoroughly
wash it in solvent. After that, push the fi lter into the tank
completely.
NOTE
If the fi lter is hard due to dust and dirt, replace it.
Chain oil fi lter (Fig. 41)
