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)
Oil Change Procedure
Please follow these steps when changing the oil:
(1) Set the blower down on a level surface.
(2) Put 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). Put 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 man-
ner 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.
DANGER
• Before inspection and maintenance, stop the engine and allow it to cool down. Remove the spark plug and plug cap.
- Otherwise the operator may suffer burn or serious injury due to an accidental start-up.
• After inspection and maintenance, make sure 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, make sure 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 become dirty 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).
