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.
