INSPECTION AND MAINTENANCE
1. Replacement of engine oil
Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of replace-
ment.
Interval of replacement:
After first 20 operating hours, followed by every 50 operating hours
Recommended oil:
SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for automobile)
In replacement, perform the following procedure.
(1) Confirm that the tank cap is tightened securely.
(2) Detach the oil cap.
• Keep the oil gauge free from dust or dirt.
(3) Tilt the machine in order as shown in Figure 1.
• Drain the oil in a container.
(4) Orient the machine as shown in Figure 2 and refill oil to the
shelf inside the oil pipe.
(5) After refill, securely tighten the oil gauge. Insufficient tightening
of the oil gauge will lead to oil leakage.
DANGER
• Before inspection and maintenance, stop the engine and allow it to cool. Remove the spark plug and plug cap.
- If inspection or maintenance is attempted immediately after engine stop or with the plug cap left attached, the operator may suffer burn or
an accident due to careless startup.
• After inspection and maintenance, be sure to confirm that all parts are assembled. Then, proceed to operation.
DANGER
• In general, the engine main unit and engine oil still remain hot just after the engine is stopped. In replacement of oil, confirm that the engine
main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of scald. Allow sufficient time after stopping engine
for the engine oil to return to the oil tank to ensure accurate reading of the oil level indicator.
• If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.
Points in replacement of engine oil
• Never discard replaced engine oil in garbage, earth or sewage ditch. Disposal of oil is regulated by law. In disposal, always follow the relevant
laws and regulations. For any points remaining unknown, contact Authorized Service Agent.
• Oil will deteriorate even when it is kept unused. Perform inspection and replacement at regular intervals (replace with new oil every 6 months).
