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

conrm that the engine main unit and engine oil are sufciently cooled down. Otherwise, there may remain a risk of
scald.
Note: If the oil lled above the limit, it may be contaminated or may catch re with white smoke.
Interval of replacement: Initially, every 20 operating hours, and subsequently every 50 operating hours
Recommended oil: SAE10W-30 oil of API Classication SF Class or higher (4-stroke engine oil for automobile)
