1. ENGINE OIL CHANGE (See Fig.

)

Change engine oil every 50 hours.

(For new engine, change oil after 20 hours.)

filler cap while the engine is warm.

oil until it reaches the upper level on the oil filler cap.

■■

specified level as directed on page 5.

quantity of the engine oil is not sufficient, the

engine damage will result and its life will be

greatly shortened.

pressure with the slip ring changes and causes a

roughened surface on the slip ring, resulting in

irregular generator performance.

performance is irregular.

If the brush is 5 mm (0.2 in.) long or less, replace it

with a new one.
