Limit value
9.5 The running is not stable
5.One of the nozzles is bad
5.Check and replace the bad nozzle
1.There is some air in the fuel
system
1. Check the air leakage and remedy the
fault then eliminate the air in the fuel
system
2.The speed-regulating slide cushion lost
its flexility
3.The speed-regulating level is worn or
not flexible
4.The fuel distributed to each cylinder is
not even
2. Send the oil pump to the service station
3. Send the oil pump to the service station
4. Send the oil pump to the service station
9.6 Stopping the engine suddenly
b) The oil pressure is too low and the lube
oil is not enough to cause the crankshaft
sticking to cylinder.
b) Send it to the service station and
check the lubricating system.
The cause of the fault
1.The fuel in the tank is used out
2.There is some air in the fuel line
3.The fuel filter is clogged
4. The plunger and inner oil ring is snapped
5. The plunger spring is broken
6. The solenoid plug of fuel pump is not
electrified
7. The denticulate belt is broken
8. The crankcase can't crank
a) The piston sticks to the cylinder
Elimination method
1. Add fuel to the fuel tank
2. Exliminate the air in the fuel line
3. Clean or replace the element
4. Send the oil pump to the service station
5. Send the oil pump to the service station
6. Check the circuit
7. Replace and test
8. Replace and test
a) Send it to the service station
9.7 The engine can't stop when the solenoid is cut off
3. The switch of the solenoid doesn't work 3. Replace or repair
The cause of the fault
1. There is some fault about the solenoid
2. The seal surface of the solenoid loses
its seal function
Elimination method
1. Replace the solenoid and clean the
element
2. Send the oil pump to the service station
