Points in replacement of engine oil
• Never discard replaced engine oil in garbage, earth or sewage ditch. Disposal of oil is regulated by law. In disposal, always follow the
relevant laws and regulations. For any points remaining unknown, contact Authorized Service Agent.
• Oil will deteriorate even when it is kept unused. Perform inspection and replacement at regular intervals (replace with new oil every 6
months).
2. Cleaning of air cleaner
Interval of Cleaning and Inspection: Daily (every 10 operating hours)
– Remove the air cleaner cover-fixing bolts.
– Pull the lower side of the cover and detach the air cleaner cover.
– Fully close the choke, and ensure that the carburetor is free from dust or dirt.
– Remove the air cleaner element, wash element with neutral detergent diluted
with tepid water, and let element dry. Replace the element in the position
indicated by the dotted line in fig. 1.
– Use a piece of paper to wipe off any oil adhering to the air cleaner cover and
plate breather.
– Immediately after cleaning, attach the cleaner cover and use the attachment
bolt for fixing. (When remounting, position the upper part of the cover first
and then the lower.).
3. 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 0.7-0.8mm
(0.028"-0.032"). If the gap is too wide or too narrow, adjust it. If the spark
plug is clogged with carton or fouled, clean it thoroubhly or replace it.
CAUTION: Never touch the spark plug connector while the engine is running
(danger of high voltage electric shock).
4. 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 filler (1) of the suction head is used to filler 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.
