its original position after drying it thoroughly.
• If the air cleaner is distorted or damaged, please
replace it with a new one.

interior will suffer abnormal wear if it is operated
without filter or if continually operated with a
distorted or damaged filter.

hand.

MAINTENANCE

To check the fuel filter
• After every 25 hours of operation, empty the fuel
tank, detach the fuel filter from the tank, and
remove all dirt. If the filter is too clogged, please
replace it with a new one.
• If the fuel filter is clogged, the engine speed may
be limited or speed fluctuations may occur.
• If the engine is operated without a fuel filter, dirt
will accumulate in the carburetor and cause it to
malfunction
To check the spark plug
• Do not touch the spark plug with your bare hands
immediately after operation, as there is the risk of
burns due to high temperature.
• After every 25 hours of operation, detach the
spark plug and remove dirt from the electrodes
with a wire brush or similar.
