Side case (Fig. 33)
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.
Fuel fi lter (Fig. 34)
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. 35)
Remove the oil fi lter and thoroughly wash it in solvent.
Cleaning the cylinder fi ns (Fig. 36)
When wood chips are caught between cylinder fi ns (38), the engine
may overheat, resulting in lower output. To avoid this, always keep
cylinder fi ns and fan case clean.

Cleaning the muffl er (Fig. 37)
Remove the muffl er and spark arrestor, if so equipped, and clean out
any excess carbon from the exhaust port or muffl er inlet every 100
hours of operation.
For long-term storage
Drain all fuel from the fuel tank. Start and let engine run until it stops.
Repair any damage which has resulted from use. Clean the unit with
a clean rag, or the use of high pressure air hose. Put a few drops of
two-cycle engine oil into the cylinder through the spark plug hole,
and spin the engine over several times to distribute oil.
Cover the unit and store it in a dry area.
