Break-In Period
Perform the following break-in and maintenance procedures carefully.
1. Fill the fuel tank with gasoline. Always
exercise extreme caution whenever han-
dling gasoline.
2. Check the oil level. Add the recom-
mended oil as needed to maintain the oil
level in the proper range. See page 99.

warm up before operating.

at sustained idle.

hours), change the engine oil and the
