Troubleshooting
Engine does not start
CAUSE
SOLUTION
Cold weather, machine oil be-
comes more adhesive
Fill machine oil into crankshaft case after preheated. Fill machine
oil into inlet manifold. Disassemble the connection belt of match-
ing machine and then start the diesel engine. Stop the engine
when the engine becomes hot and reassemble the belt. Start the
engine again.
Fuel system malfunction; fuel
mixed with water
Clean fuel tank filter and fuel pipe, change fuel.
Fuel viscous or too thin
Use the specific fuel.
Air inside fuel system
Drain out the air and tighten each connector of fuel pipe.
Combustion not complete
The spray nozzle is not good, delivery angle is not correct, gas-
ket of cylinder head is leaky and the pressure of compression is
not enough. Fix the cause.
Diesel fuel delivery interrupted
Diesel fuel is too little in the fuel tank. Fill the fuel into the fuel
tank. If the fuel pipe and fuel are obstructed or leaky, remedy
them.
Not enough compression pressure
in the cylinder; cylinder head nut
not tighten, or gasket of cylinder
damaged or leaky
Tighten the nut of cylinder head, according to diagonal line se-
quence and standard requirement, check gasket of cylinder, if
changing the gasket, tighten the nut of cylinder head once again
after pre-running the diesel engine.
Piston ring gap too big because of
wear
Change the piston ring.
Each piston ring gap lines up,
causing leakage
Set each piston gap at an angle of 120°.
Piston rings seriously stuck or
even broken
Clean with diesel fuel or change rings.
Gas valve leakage
Grind the gas valves; if the vestige is too deep, please send it to
the factory for remedy.
Valve stem clipped on guide pipe
Disassemble the gas valve and clean the stem and guide pipe.
