(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 engine, 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.
