be performed after 20 hours of operation.
Thereafter replace the engine oil filter
every 200 hours.
■
When installing a new oil filter, apply oil to
O-ring, attach the oil filter in position and
tighten 2/3 turns by hand or with wrench
after touching the O-ring to the sealing
surface of engine.
■
Run the engine for a minute ; stop the
engine and check for oil leakage around
the oil filter and recheck the oil level.
CLEANING AIR CLEANER
A dirty air cleaner element will cause
starting difficulty, power loss, engine
malfunctions, and shorten engine life
extremely.
Always keep the air cleaner element clean.
Replaced the air cleaner element set more
often in dusty environments.
The air cleaner paper inner element and
urethane foam outer element can be
removed after removing knob and air
cleaner cover. When installing, set the
paper element and urethane foam on the
air cleaner base. Check that the grommet is
in position, and then install the cover with
knob tightened securely.

Wash and clean the urethane foam in
kerosene. Saturate in a mixture of 3 parts
kerosene and 1 part engine oil, and then
squeeze to remove excess oil. Clean or

environments)
