2-2.3 Checking the air filter
(1) Lo
osen the butterfly nut, take the cover of the air
filter off and take the air filter element out.
Do n
ot wash the air filter element.
When t
he performance of the engine decreases or
when t
he color of the exhaust gases is bad, exchange
the f
ilter element. Never start the engine without the
air filter as foreign objects may enter the intake and damage the engine.
Use d
ry compressed air (with pressure about 28 PSI to blow the dust out
in
the e
lectric control cabinet and at the surface of the generator. Check to see
how c
lean the surface of the sliding ring is. Check the pressure of the carbon
brush. A
lso, check whether the position of the carbon brush at the slide rig is
correct and the fixture is reliable with a good contact.
2-2.5 The fuel and oil in a new engine is drained before sold. Before you start the
engine, p
lease fill the fuel tank and engine oil first.
2-3 Checking the operation of the diesel engine
2-3.1 Low-pressure oil switch.
CF d
iesel engines have a low-pressure sensor system where if the oil pressure
drops t
oo low, the sensor will shut the engine off. The purpose of having this
system is to e
nsure that the engine does not seize up. If there is not enough oil
in the e
ngine, the temperature of the oil will be raised too high. On the
contrary, if t
here is too much oil in the engine, the engine oil can slow the
engine down considerably.
