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)
Oil Change Procedure
Please follow these steps when changing the oil:
(1) Set the blower down on a level surface.
(2) Place a waste oil container under the drainage hole (1) to catch the oil
as it drains out. The container should have a capacity of at least 220 ml
to be able to catch all of the oil.
(3) Loosen the oil drain bolt (2) to let the oil drain out. Be careful not to
allow oil to get on the fuel tank or other parts.
Caution: Be careful not to lose the gasket (aluminum washer) (3). Place
the oil drain bolt (2) in a location where it will not accumulate
dirt.
(4) Remove the oil cap (4). (Removing the oil cap (4) allows the oil to drain
easily.)
Caution: Be sure to set the oil cap (4) down in a location where it will not
accumulate dirt.
(5) As the level of the oil being drained decreases, tilt the blower over on to
the side with the drain so that the oil will completely drain out.
(6) After the oil has completely drained out, tighten the oil drain bolt (2)
securely. If the bolt is not tightly fastened, this may result in an oil leak.
Caution: Do not forget to put the gasket (aluminum washer) (3) back on
when reattaching the drain plug.
(7) Adding oil during the oil change procedure is performed in the same
manner as the separately explained procedure for adding oil whenever
the level is insufficient. Always add oil by filling from the opening under
the oil cap.
(Specified oil level: Approximately 220 ml)
(8) After filling with oil, tighten the oil cap (4) securely to prevent oil leaks.
• 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).
