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
a) Remove the spark plug
ATTENTION: never touch the spark plug immediately after the engine is stopped to avoid getting
burnt by the high temperature.
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 repaired as follows:
2. Drain off the fuel from the fuel tank.
3. Refill the pump with water and start the engine. Keep it running at low speed until the fuel is
used up.
4. Remove the spark plug and refuel 1-2cc of motor oil for 2-cycle engine into the cylinder. Pull
out the hand starter 2-3 times.
5. Replace the spark plug as it was and pull the starter. Release the starter grip at the position
where you feel it hard to pull.
6. Drain off the water in the pump thoroughly and wipe out the water with a rag
b) Please remove or brush the dirt in the
electrode with a brush every 25 hours.
Please adjust the gap of the spark plug
electrode gap between 0.7-0.8mm.
