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.
ATTENTION: 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.
Note: If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.
Interval of replacement: Initially, every 20 operating hours, and subsequently every 50 operating hours
Recommended oil:
SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)
1) Remove drain bolt. At this time, be sure not to mislay drain bolt's gasket.
Also, be sure to place both items in a clean location where they will not
become dirty.
2) Remove drain bolt and then remove oil cap to drain out oil from drain hole.
3) Once the oil has been drained, combine gasket and drain bolt, and tightly
secure drain bolt, so that it will not loosen and cause leaks.
* Use cloth to fully wipe off any oil attached to bolt and equipment.
4) Set the engine level, and gradually fill up to upper limit mark with new oil.
5) After filling, tightly secure oil cap, making sure that it does not become
loose. If oil cap becomes loose, oil may leak out.
