CLEANING OF AIR CLEANER
DANGER: INFLAMMABLES STRICTLY PROHIBITED
Interval of cleaning and inspection: Daily (every 10 operating hours)
- Turn the choke lever (D) to the full close side, and keep the carburetor off
from dust or dirt.
- Loosen the fixing bolt (G).
- Remove the air cleaner cover
- Remove the elements (B) (F) and tap them to remove dirt.
- If the elements are heavily contaminated:
Remove the elements, immerse them in warm water or in water-diluted
neutral detergent, and dry them completely. Do not squeeze or rub them
when washing.
- Before attaching the elements, be sure to dry them completely. Insufficient
drying of the elements may lead to difficult startup.
- Wipe out oil adhering around the air cleaner cover and the breather part
with waste cloth.
- Fit the element (sponge) (B) into the element (felt) (F).
Fit the elements into the plate (C) so that the sponge faces the air cleaner
cover.
- Immediately attach the cleaner cover and tighten it with fixing bolts. (In
remounting, first place the upper claw, and then the lower claw.)
NOTICE:
- Clean the elements several times a day, if excessive dust adheres to it.
Dirty elements reduce engine power and make starting engine difficult.
- Remove oil on the elements. If operation continues with the elements
remaining not cleared of oil, oil in the air cleaner may fall outside, resulting
in contamination of the environment.
- Do not put the elements on the ground or dirty place. Otherwise they pick
up dirt or debris and it may damage the engine.
- Never use fuel for cleaning the elements. Fuel may damage them.
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).
(A) by pulling its bottom side.
