Maintaining
Your
Engine
WARNING: Shut off the engine before
performing any maintenance. To
prevent accidental start-up, disconnect
the spark plug boot.
IMPORTANT: If engine must be tipped to transport
equipment or to inspect, keep spark plug side of engine
up. Transporting or tipping engine spark plug down may
cause smoking, hard starting, spark plug fouling, or oil
saturation of air cleaner.
Periodic inspection and adjustment of the engine is
essential if high level performance is to be maintained.
Regular maintenance will also ensure a long service life.
The required service intervals and the kind of mainte-
nance to be performed are described in the table below.
Follow the hourly or calendar intervals, whichever occur
first. More frequent service is required when operating in
adverse conditions.
