Maintenance and repair

1. Periodic maintenance plan

2. Maintenance of air filter

Dirty air filter will prevent air from entering the carburetor, resulting in carburetor failure, intensified wear of gasoline engine and insufficient output power. The air filter should be maintained regularly. If the filter element of the air filter is blocked by dirt, please clean the filter element and the interior of the air filter with gasoline. Put a few drops of engine oil on the cleaned filter element, screw the engine oil dry and install it into the inner cover of the air filter. Note: during cleaning, do not let dirt enter the engine air inlet, otherwise the engine will be damaged.

3. Spark plug maintenance

In order to ensure the normal operation of the engine, the gap of the spark plug must be appropriate and free of deposits. The reasonable clearance of spark plug is 0.8 ~ 0.9 mm, which shall be checked frequently. If it is too large or too small, it shall be adjusted. Note: do not use spark plugs with incorrect calorific value.

4. Fill with grease

Inject lubricating grease every 20 hours, about 30 ~ 50g.

5. Long term storage

When the machine is not used for a long time, in order to start smoothly next time, the following procedures shall be followed for maintenance:

5.1 drain the fuel in the oil tank and carburetor;

5.2 remove the spark plug, add an appropriate amount of engine oil to the cylinder block from the spark plug hole, gently pull the starter 2 ~ 3 times to make the piston at the top dead center, and then install the spark plug;

5.3 wipe the outer surface of the machine with a soft cloth soaked in engine oil and keep the machine in a ventilated and dry place until next use.
