INSPECTION AND MAINTENANCE
• Before inspection and maintenance, stop the engine and allow it to cool. Remove also 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.
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
replacement.
• 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. In addition just after of the
engine stopping because oil does not finish to return in the oil case, becomes cause of the oil inserting too much
• If the oil filled above the limit, it may be contaminated or may catch fire with white smoke.
Interval of replacement: Initially, every 20 operating hours, and subsequently 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 gauge.
- Keep the oil gauge free from dust or dirt.
3) Use the provided oil extraction bottle to remove the old oil from the oil
reservoir.
• Squeeze the body of the bottle to and insert the nozzle into the oil.
Release pressure on the bottle to draw the old oil from the oil reservoir.
• When the oil reservoir is almost empty, tilt the power sprayer unit slightly
in order to facilitate removal of the remaining engine oil.
4) Return the engine to level. Using the lubricant refill bottle, fill with new oil up
to the top of the oil reservoir.
5) Replace and securely tighten the dip stick. Insufficient tightening will lead to
oil leaks.
• Use the provided oil extraction bottle and lubricant refill bottle for their
intended purposes.
