Fault
Number
2. Check the tightening screw of the mixer to see whether it is loosen or not,
check all of the connection of the gas inlet pipe and mixer to see whether it
is leaking or not.
4. Check the LPG, NG pressure to see whether it is normal or not.
5. Check the screw of pressure regulating valve to see whether it is loosen
or not.
6. Check the LPG tank surface to see whether it is frosted or not.
Idling unstable
1. The top dead center signal of cylinder one is not correct.
2. Speed signal is not correct.
Elimination method: check or replace the sensor.
3. Temperature of pressure reducing is too low.
4. Pressure reducer can not work normally, repair or replace.
5. Cylinder blow by.
Elimination method: check the cylinder cap of the screw, when necessity
replace the cylinder cap seal and check cylinder jacket ledge of the altitude
difference compared with the surface of the unit.
Engine cannot
operating stably
3
1. Low pressure pipe buckled or too long; (settle)
2. Ignition system with not enough ignition power.
3. High tension line and FBT is not connected well.
4. High tension and spark plug is not connected well.
5. Some of the cylinders miss the ignition.
Handling method of 3, 4, 5
1) Pull out the spark plug, observe pole top to see whether it has burned
trace, if there is, then replace the spark plug.
2) Use the multimeter (XKΩ GEAR) test the resistance of the high tension
line, if it disconnection, then change the high tension line.
6. Under pressure of the cylinder;(check the adjust valve and check or
replace the packing ring)
7. High pressure pipe blocked or out of shape;(sweep or clear up)
8. Dirtiness or leakage that changes the vacuum level; (overhauling or clean
9. Mixer is not sealed well; (replace)
10. The joint part of mixer and throttle leaking; (settle)
12. Check whether gas is up to standard.
13. Check the gas to see whether it is up to standard.
14. Pressure reducer can not offer enough heat, check the inlet/outlet pipe
connection, use the hands to touch the reducer shell, if the water cycle can
not work smoothly, it will be warm, or check the waterway to see whether it
is blocked or not.
16. Voltage output instability; (adjust or change)
Engine with not
enough power,
power, tumbling,
consumption of the
NG increases.
