❶ Loose or broken bolts and nuts
❷ Clean air cleaner element
❸ Enough clean engine oil

❺ Enough gasoline
❻ Safe surroundings
❼ Excessive vibration, noise
2. PERIODIC INSPECTION
Periodic maintenance is vital to the safe and effi cient operation
of your engine.
Check the table below for periodic maintenance intervals.
Should the engine be operated in extremely dusty condition or
in heavier loading condition, the maintenance intervals must be
shortened depending on the contamination of oil, clogging of
fi lter elements, wear of parts, and so on.
3. INSPECTING THE SPARK PLUG
(See Fig. 󱯚-②)
(1) Clean off carbon deposits on the spark plug electrode using
a plug cleaner or wire brush.
(2) Check electrode gap. The gap should be 0.6 mm to 0.7mm.
Adjust the gap, if necessary, by carefully bending the side
electrode.
Recommended Spark Plug : BR-6HS (NGK)
4. ENGINE OIL CHANGE (See Fig. 󱯚-③,④)
Initial oil change : After 20 hours of operation
Thereafter : Every 100 hours of operation
(1) When changing oil, stop the engine and loosen the drain
plug. Drain the used oil while the engine is warm. Warm oil
drains quickly and completely.
CAUTION
To prevent injury, pay attention to the hot oil.
(2) Re-install the drain plug before refi lling oil.
