BEFORE START OF OPERATION

Inspection and refill of engine oil
– Perform the following procedure, with the engine cooled down.
– While keeping the engine level, remove the oil gauge, and confirm that the oil is filled within the upper and lower limit marks.
When the oil is in short in such a way that the oil gauge touches the oil only by its tip, in particular with the oil gauge remaining inserted in the
crankcase without screwing-­in (Fig. 1), refill new oil near the port (Fig. 2).
– For reference, the oil refill time is about 15 h (refill frequency: 15 times).
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 - 20)
Recommended oil: SAE 10W-­30 oil of A PI Classification, Class SF or higher (4-­stroke engine for automobile)
Oil volume: Approx. 0.1 L
Note: If the engine is not kept upright, oil may go into around the engine, and may be refilled 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 refill 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.
– As an example to keep the oil gauge clean, it is recommended to insert the oil gauge on its knob side into the engine cover, as shown
in Fig. 3.
If oil adheres around
this tip, refill new oil.

(1) Keep the engine level, and detach the oil gauge.
(2) Fill oil up to the edge of the oil refill port. (Refer to Fig. 2).
Feed oil with the lubricant refill container.
(3) Securely tighten the oil gauge. Insufficient tightening may cause oil leakage.
Point 2 in Replacement of oil: "If oil spills out"
– If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will
contaminate the engine. Be sure to wipe out spilt oil before start of operation.
