WARNING: Shut off the engine before performing any type of maintenance. To prevent accidental start-up, discon- nect the spark plug boot.

IMPORTANT: If engine must be tipped to transport equipment or to inspect, keep spark plug side of en- gine up. Transporting or tipping engine with 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 type 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.
