b) Fuel tank cap & filter
Clean filter after 50h of operation or every 3 months.
Remove the fuel
tank cap and filter
Remark:
If the breather valve of the fuel tank filter and the fuel tank cap are clogged up, the engine may not
work normally or run at an unsteady speed.
Operating the engine for a long time without a fuel filter could lead to the scuffing of cylinder bore.
6.2.3- Spark plug
ATTENTION: never touch the spark plug immediately after the engine is stopped to avoid getting
burnt by the high temperature.
a) Remove the spark plug
b) Please remove or brush the dirt in the electrode with a brush every 50 hours or every month.
c) Adjust the gap of the spark plug electrode between 0.6-0.7mm.
Remark: Too much suction of the fuel or using wasted or regenerated oil can pollute the spark plug
electrode and make it hard to start the engine.
6.2.4- Air-cooling passage
Please check the air-cooling passage and cylinder radiator and remove the attached impurity after it
is used for 25 hours
Remarks:
- If the air-cooling passage and the cylinder radiator are clogged up by dirt, the engine may
overheat, causing failure
- Never insert anything in the air-cooling passage during the operation. Touching the rotating part is
very dangerous
6.3- Long Term Storage
When it is not in use for a long time and needs storing, please drain off the fuel in the fuel tank and
the cylinder. The long-term storage with fuel in them will cause the block inside the cylinder and
the failure of the engine (hard to start or lower output of the power).
1. Please leave the tank cap a bit open in storage. Being tightened may lead to the deformation of
the cap. If the pump is not in use for more than a mouth, store it at the places where there is less
dust and lower humidity after it is maintained as follows:
2. Drain off the fuel from the fuel tank.
Wash the filter in
nonflammable solvent
dry it thoroughly. Replace filter and cap
