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. Insufficient drying
of the element may lead to difficult 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.

CHECKING THE SPARK PLUG

– Only use the supplied universal wrench to remove or to install the spark plug.
– The gap between the two electrodes of the spark plug should be 0.7 - 0.8 mm
(0.028" - 0.032"). If the gap is too wide or too narrow, adjust it. If the spark
plug is clogged or contaminated, clean it thoroughly or replace it.
CAUTION: Never touch the spark plug connector while the engine is running
(danger of high voltage electric shock).
SUPPLY OF GREASE TO GEAR CASE
– Supply grease (Shell Alvania 2 or equivalent) to the gear case through the
grease hole every 30 hours. (Genuine MAKITA grease may be purchased
