Gear case (Fig. 3-5, 5B)
Apply a good quality lithium based grease through the grease fitting until a small amount comes out between the
cutter blades and the gear case.
NOTE!
Lubrication should be applied at 50 hour intervals and more frequent at heavy use.
Fuel filter (Fig. 3-6)
Remove the fuel filter from the fuel tank and thoroughly wash it in solvent. After that, push the filter into the tank
completely.
NOTE!
If the filter is hard due to dust and dirt, replace it.
Cleaning the cylinder fins (Fig. 3-7)
When wood chips are caught between cylinder fins (1),
the engine may overheat, resulting in lower output. To
avoid this, always keep cylinder fins and fan case clean.
Every 100 Operating hours, or once a year (more often if
conditions require), clean fins and external surfaces of
engine of dust, dirt and oil deposits which can contribute
to improper cooling.
Cleaning the muffler (Fig. 3-8)
Remove the muffler and spark arrestor (if so
equipped), and clean out any excess carbon
from the exhaust port or muffler 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.
