Every 10 to 15 hours of operation:

■ Remove and clean the spark plug.

Adjust the spark plug electrode gap to

0.6 mm (0.024 in). If the spark plug

must be replaced, use only an NGK

BPM8Y or equivalent spark plug of

the correct heat range. See Figure

15.

CAUTION!

Before removing the spark plug,

clean the area around the plug to

prevent dirt and debris from getting

into the engine’s internal parts.

Clean the spark plug

and check the gap at

the electrode.

1. Clean dirt from grease tting (A) and grommet (B).

2. Do not force grease. Too much pressure will force grease past seals and

cause damage. Apply 1-2 pumps of grease every 20 hours of operation.

3. Remove the grommet next to the grease icon then add grease as illustrated.

4. Reinstall the grommet securely in the hole otherwise, it may become lost.
