CLEANING OF AIR CLEANER
DANGER: INFLAMMABLES STRICTLY PROHIBITED
Interval of Cleaning and Inspection: Daily (every 10 operating hours)
– Remove the air cleaner cover attachment bolt.
– Pull the bottom of the cover to remove the air cleaner cover.
– Fully close choke lever to prevent dust and dirt getting into carburetor.
When element (sponge) becomes dirty with oil, squeeze it with full force.
– When the element (sponge) is extremely dirty, remove it, and wash in neutral
detergent diluted with warm or cold water, and dry thoroughly.
– Reassemble the element after thorough drying. Insufficiently dried element
may cause poor engine starting.
– Use rag to wipe off oil from around area of air cleaner cover and plate’s
breather section.
– As soon as cleaning is finished, replace air cleaner cover, and tightly secure
bolt. (For mounting, clip on upper hook edge and then clip on lower hook
edge.)
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.
CLEANING OF FUEL FILTER
WARNING: INFLAMMABLES STRICTLY PROHIBITED
Interval of Cleaning and Inspection: Monthly (every 50 operating hours)
Suction head in the fuel tank
– The fuel filter (1) of the suction head is used to filter the fuel required by the
carburetor.
– A periodical visual inspection of the fuel filter is to be conducted. For that
purpose open the tank cap, use a wire hook and pull out the suction head
through the tank opening. Filters found to have hardened, been polluted or
clogged up are to be replaced.
– Insufficient fuel supply can result in the admissible maximum speed being
exceeded. It is therefore important to replace the fuel filter at least quarterly to
ensure satisfactory fuel supply to the carburetor.
0.7 mm - 0.8 mm
(0.028” - 0.032”)
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).
