Shut off the engine before performing any maintenance. To prevent accidental start-up, remove safety key (if equipped),
disconnect the spark plug wire and ground against the engine.
General Recommendations
If engine must be tipped to transport equipment, 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 to maintaining engine performance and service life.
Required service intervals and maintenance are described in the table below. Follow the hourly or calendar intervals as listed. More
frequent service is required when operating in adverse conditions.
If the engine has been running, the muffler will be very hot. Allow engine and muffler to cool before performing
any maintenance.
