Inspection and refill of engine oil
Perform the following procedure, with the engine cooled down. –
Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit –
marks of the oil pipe (Fig. 2).
Fill with oil to upper limit mark if oil is insufficient (oil level is close to lower limit mark) (Fig. 3). –
The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap. –
However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of
oil pipe.
For reference, the oil refill time is about 10h (10 times or 10 tanks of gas before oil needs to be refilled). –
If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 19)
Recommended oil: SAE 10W-30 oil of API Classification, Class SF or higher (4-stroke engine for automobile)
Oil volume: Approx. 0.08L
NOTE: If the engine is not kept upright, oil may pool in other parts of the engine. The oil levelgauge may give an incorrect reading for oil level.
Do not fill with oil if engine is not upright. If the oil is filled above the limit, the oil may be contaminated or may catch fire with white
smoke.
Point 1 in Replacement of oil: “Oil cap”
Remove dust or dirt near the oil refill port, and detach the oil cap. –
Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or –
wear on the engine parts, which will result in troubles.

Oil
Top up with oil until
oil level reaches
internal stepped
section (upper
limit).
The area between the
external upper and lower
limits is transparent, so
oil level can be checked
externally against these
marks.
(2) Fill with oil to upper limit mark. (see Fig. 3)
Use oil bottle when filling.
(3) Securely tighten the oil cap. Insufficient tightening may cause oil leakage.
