CLEANING OF AIR CLEANER
DANGER: INFLAMMABLES STRICTLY PROHIBITED
Interval of Cleaning and Inspection: Daily (every 10 operating hours)
– Turn the choke lever to the full close side, and keep the carburetor off from
dust or dirt.
– Remove the air cleaner cover-fixing bolts.
– Pull the cover lower side and detach the air cleaner cover.
– If oil adheres to the element (sponge), squeeze it firmly.
– For heavy contamination:
1) Remove the element (sponge), immerse it in warm water or in water-
diluted neutral detergent, and dry it completely.
2) Clean the element (felt) with gasoline, and dry it completely.
– Before attaching the element, be sure to dry it completely. Insufficient drying
of the element may lead to difficult startup.
– Wipe out with waste cloth, oil adhering around the air cleaner cover and plate
breather.
– Immediately after cleaning is finished, attach the cleaner cover and tighten it
with fixing bolts. (In remounting, first place the upper claw, and then the lower
claw.)

POINTS ON 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).
Points in Handling Air Cleaner Element
– Clean the element several times a day, if excessive dust adheres to it.
– If operation continues with the element remaining not cleared of oil, oil
in the air cleaner may fall outside, resulting in oil contamination.
4) Detach the oil gauge, and drain oil, tilting the main unit toward the oil refill
port.
Drain oil in a container for orderly disposal.
5) Keep the engine level, and feed new oil up to the edge of the oil refill port.
In refill, use a lubricant refill container.
6) After refill, securely tighten the oil gauge. Insufficient tightening of the oil
gauge will lead to oil leakage.
