SERVICE AND MAINTENANCE

WARNING

Shut off the engine before performing any maintenance. To prevent accidental start-up, remove the safety key or

disconnect the spark plug wire and ground against the engine.

General Recommendations

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 occurs first. More frequent service is required when operating in adverse

conditions.

NOTE: If engine must be tipped to transport equipment or inspect, 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.

WARNING

If the engine has been running, the muffler will be very hot. Allow engine and muffler to cool before performing any

maintenance.

Changing the Oil

To avoid engine damage, it is important to:

Check oil level before each use and every 5 operating hours when

the engine is warm. See Checking Oil Level/Adding Oil on page

Change the oil after the first 5 operating hours and every 50

operating hours thereafter. Engine should still be warm but NOT

HOT from recent use.

WARNING

If the engine has been running the muffler, engine head

and spark plug will be very hot. Be careful not to touch

any of these components until they have cooled.

WARNING

Before tipping engine or equipment to drain oil, drain

fuel from tank by running engine until fuel tank is empty.

1. Carefully disconnect the spark plug wire (a) and keep it away

from the spark plug (b). Refer to Figure 9 for spark plug

location.

IMPORTANT: Keep the disconnected spark plug wire securely

away from the metal parts where arcing could occur.

NOTE: Carefully attach the spark plug wire to the grounding

post, if provided.
