2. Air filter maintenance
Check the air filter for dirty before and after each use. If it is too
dirty, it will cause the engine to start hard, black smoke, and no power.
If the filter element is paper, remove the filter element and remove the
dust attached to it; If the filter element is made of sponge, after cleaning
with gasoline, apply some lubricating oil on the filter element to keep
the filter element moist, which is more conducive to dust absorption.
However,the other layer surrounded by the sponge cannot be washed
with water. After washing, it will cause the pores to close and affect the
engine work (the inner layer is made of paper). When cleaning, use an
air gun to blow it clean.

3. Radiator maintenance
The main function of the radiator is to eliminate noise and heat.
When the machine is working, the sundries may be covered on the heat
sink, affecting its heat dissipation function. In severe cases, the engine
may be damaged. Therefore, after each use of the machine, the debris on
the heat sink should be carefully cleaned.
4. Fuel maintenance
Every time the fuel is exhausted, the machine should be allowed
to rest for ten minutes before refueling. Otherwise, the fuel will be on
fire due to the high temperature of the machine. When refueling, please
add the same amount of fuel according to the fuel capacity in the “Host
Parameters (page 11)”; if you add too much oil, it will block the vent
hole on the oil cover, causing the oil level to be free from pressure and
unable to supply oil to the engine.
