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: I n 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)
In replacement, perform the following procedure.
1) Confirm that the fuel tank cap is tightened securely.
2) Place large container (pan, etc.) under drain hole.
3) Remove drain bolt and then remove oil cap to drain out oil from drain hole.
At this time, be sure not to mislay drain bolt's gasket, or to dirty any of the
removed components.
4) Once all 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.
Alternative draining method
Remove oil cap, tilt Petrol Brushcutter toward oil filler hole, and drain out oil.
Collect oil in container.
5) Set the engine level, and gradually fill up to upper limit mark with new oil.
6) After filling, tightly secure oil cap, so that it will not loosen and cause leaks.
If oil cap is not tightly secured, it may leak.
