FUEL FILTER
Check the fuel filter periodically. Replace it if it is too dirty
(Fig. 45).
OIL PUMP (automatic / adjustable)
Flow adjustment is pre-set by the manufacturer. Oil flow
can be adjusted by the operator according to specific
requirements. This is accomplished by the special
adjusting screw (Fig. 46). Oil flow occurs only when the
chain is moving.
Never use or operate with used oil.
STARTER ASSEMBLY VENT CLEANING
Use a brush or compressed air to keep the cooling
louvers of the starter assembly free and clean (Fig. 47).
ENGINE / DECOMPRESSION VALVE
Periodically clean the cylinder fins (Fig. 48) with
compressed air or a brush. Dangerous overheating of the
engine may occur due to impurities on the cylinder.
Check the base of the decompression valve; clean away
any residues, which could cause the valve to stay open.
SPARK PLUG
Clean the spark plug and check the electrode gap
periodically (Fig. 49).
Use a Champion RCJ-7Y or equivalent with the same
thermal grade.
