REPLACEMENT OF ENGINE OIL
WARNING:
• The engine and engine oil is still hot just after stopping engine. Allow sufficient time for the
engine and engine oil to cool down. Otherwise a skin burn may result.
CAUTION:
• Before changing oil, check for a suitable way to dispose of old oil. Do not pour it down into
sewage drains, onto garden soil or into open streams. Your local zoning or environmental
regulations will give you more detailed instructions on proper disposal.
Deteriorated engine oil shortens the life of the engine. Be sure to check the oil and level regularly.
NOTE:
• If the oil filled above the limit, it may be contaminated or may catch fire with white smoke. Allow sufficient time after stopping engine for the
engine oil to return to the oil tank to ensure accurate reading of the oil level.
Interval of replacement: After first 20 operating hours, followed by every 50 operating hours.
Recommended oil: SAE 10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)
In replacement, perform the following procedure.
1) Place a cloth or paper towel to the area around the drain screw and oil refill port.
2) Place large container (pan, etc.) under drain hole.
3) Turn the oil gauge a little so that air can pass through oil refill port.
4) Remove the oil drain screw. Be sure to place the oil drain screw where it does not gather
dirt, dust or other foreign matter.
5) Tilt the earth auger and drain the oil into a pan or other container.
* Use cloth to fully wipe off any oil attached to bolt and equipment.
Alternative draining method
Remove the oil gauge, tilt the equipment toward oil refill port, and drain out oil.
Collect oil in container.
6) Once all the oil is drained, tightly secure the drain screw.
7) Remove the oil gauge. Be sure to place the oil gauge where it does not gather dirt, dust or
other foreign matter.
8) Keep the engine in horizontal position, and then fill with the oil up to the point of overflow-
ing the filler neck.
9) After filling the engine with oil, tightly secure the oil gauge. Ensure that the oil gauge and
the drain screw are tight. If it is not tightly secured, it may leak.
