Engine Maintenance

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 or remove grass, 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 maintenance 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.

WARNING:

If the engine has been running, the

muffler will be very hot. Be careful not to touch the

muffler.

† Service more frequently when used in dusty areas.
†† Every season or 25 hours if operating under heavy load or high ambient temperature.
