BEFORE START OF OPERATION
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 10 h (every 10 refuelling).
If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P19)
Recommended oil:
SAE 10W-30 oil of API Classification, Class SF or higher (4-stroke engine for automobile)
Oil volume:
Approx. 0.08 L
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 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.
(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.
