2-2.3 Checking the air filter
(1) Loosen the butterfly nut, take the cover
of the air filter off and take the air filter
element out.
Do not use detergent to wash the air filter
element. When the performance of the
engine decreases or when the color of the
exhaust gases is bad, exchange the filter
element. Never start the engine without
the air filter as foreign objects may enter
the intake and damage the engine.
(2) After replacing the air filter element,
replace the cover and tighten the
butterfly nut firmly.
Use dry compressed air (with pressure about 1.96 x 105 Pa) to blow the dust
out in the electric control cabinet and at the surface of the generator. Check to
see how clean the surface of the sliding ring is. Check the pressure of the
carbon brush. Also, check whether the position of the carbon brush at the slide
ring is correct and the fixture is reliable with a good contact.
According to the electric wiring diagram, check to see whether the connecting
wire is correct and the connected place is firm.
Use a 500 M
Ω
meter to measure the insulation resistance of the electrical part.
The resistance should be no less than 5M
Ω
. When measuring devices, make
sure the AVR is turned off. Otherwise, it will burn the AVR. (For the low noise
set, the inspection may not be performed).
2-2.4
The fuel and oil in a new engine is drained before sold. Before you start
the engine, please fill the fuel tank and engine oil first. Then, check to see
if there are air bubbles in the engine. If there are, follow these procedures.
Loosen the connecting nut between the fuel injector pump and fuel pipe.
Bleed the air from the system until there are no more bubbles. Then
replace the connecting nut and tighten it.
