INSPECTION AND MAINTENANCE
• Before inspection and maintenance, stop the engine and allow it to cool. Remove also the spark plug and plug cap.
- If inspection or maintenance is attempted immediately after engine stop or with the plug cap left attached, the operator may suffer burn
or an accident due to careless startup.
• After inspection and maintenance, be sure to confirm that all parts are assembled. Then, proceed to operation.
1. Replacement of engine oil
Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of
replacement.
• In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil, confirm that the
engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of scald. In addition just after of the
engine stopping because oil does not finish to return in the oil case, becomes cause of the oil inserting too much.
• If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.

Recommended oil:
SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)
