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.
