2. Cleaning of air cleaner
WARNING: INFLAMMABLES STRICTLY PROHIBITED
Interval of Cleaning and Inspection: Daily (every 10 operating hours)
(1) Remove the air cleaner cover-fixing bolts.
(2) Pull the cover lower side and detach the air cleaner cover.
(3) Turn the choke lever to the full close side, and keep the carburetor off from
dust or dirt.
(4) If oil adheres to the element (sponge), squeeze it firmly.

Remove the element (sponge), immerse it in warm water or in water-di-
●
luted neutral detergent, and dry it completely.
Clean the element (felt) with gasoline, and dry it completely.
●
(6) Before attaching the element, be sure to dry it completely. Insufficient drying
of the element may lead to difficult startup.
(7) Wipe out with waste cloth, oil adhering around the air cleaner cover and
plate breather.
(8) Immediately after cleaning is finished, attach the air cleaner cover and
tighten it with fixing bolts. (In remounting, first place the upper claw, and

When opening the cover, apply fingers to the main handle and plug
cover projection (Figure 1). Push up the projection and slide the
cover in the "OPEN" direction (Figure 2).
When closing the cover, slide the cover in the "CLOSE" direction till

Use an attached box wrench to remove or install the spark plug
(Figure 3).
(3) Checking the spark plug
The clearance between two electrodes of spark plug is 0.7 to 0.8
mm (Figure 4). Adjust to the correct clearance when it is too wide
or too narrow.
Clean thoroughly or replace the spark plug if it has accumulated
carbon or contaminated.
