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.
2-2.4 Checking the generator welder
(Note: Only certain welder generator sets
have an electric fan incorporated on them.)
Butterfly nut
Before starting the generator, make
sure the air switch is in the “Off”
position. Starting the generator with
the switch in the “On” switch is very
dangerous.
Air filter cover
The generator should be grounded in
order to prevent electric shock.
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 rig 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).
2-2.5 The fuel and oil in a new
engine is drained before sold.
