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 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.
