OPERATING NOTICE
When put the key at the ON position, 12V DC voltage will open the
solenoid valve in the VE pump. If the electrical bottle voltage is lower than
8V or the cable isn't connected as required, the solenoid valve won't be
opened and the engine won't start, even sudden stop will happen.

]
OPERATING NOTICE
After starting, the starter switch key shouldn't be pulled out, but placed at
ON position. If placed at the OFF position, the battery won't be charged.

]
OPERATING NOTICE
After starting, the handling lever should be put at idle or middle-low speed
position for running several minutes. Then check the all meters whether are
normal or not
whether there is abnormal sound of engine. If either of them
is abnormal, stop the engine to check and remedy it right away.
4.1.4 When the ambient temperature is below 5
C, it may be difficult to start the
engine. Warm up the intake gas, fuel, cooling water, lube oil or use some solvent
to make engine start easy.
4.2 Running
4.2.1 After starting the engine, keep it at idle state about 5 minutes then change it
into medium-speed, small-load running state. Increase the load and rotary speed
gradually along with the temperature of the cooling water and engine oil becoming
higher and higher.

OPERATING NOTICE
After starting the engine, shouldn't increase the rotary speed to high speed
or run the engine under the large load suddenly. Otherwise, it will cause the
damage of them even shorten the parts' service lives.
(3) Check the injecting pressure and the atomization quality of the fuel
Injector
Check the injecting pressure and the atomization quality of the fuel Injector every
100 hours. (Refer to the figure 7-3)
If you find there is oil leakage, atomization quality is bad and needle valve of the
nozzle is blocked, please remove and clean the injector or replace the injecting
nozzle.
If you find the oil pressure isn't up to specified value, you can adjust the pressure
regulating
spring by adding the steel shims. Refer to figure 7-4 for the structure of
the fuel injector.
[
]
OPERATION NOTICE
Fuel nozzle is a couple of exact assembly, don't replace the any of the parts
solely when clean them. Don't damage the surface of the injector lower body,
two terminal surfaces of the middle gasket, and main surface of the nozzle.
Otherwise, oil leakage will occur, affecting the quality of atomization.
