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).
– Top up 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 oil refill).
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 go into around the engine, and may be refilled excessively.
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 gauge”
– Remove dust or dirt near the oil refill port, and detach the oil gauge.
– Keep the detached oil gauge free of sand or dust. Otherwise, any sand or dust adhering to the oil gauge may cause irregular oil
circulation or wear on the engine parts, which will result in troubles.

BEFORE START OF OPERATION
(1) Keep the engine level, and detach the oil cap.
(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.

Oil
Top up with oil until
oil level reaches
internal stepped

The area between the
external upper and lower
limits is transparent, so
oil level can be checked
externally against these
marks.
