Measure the insulation resistance once a month by using 500V
insulating-resistance meter. Check if it is above 1M
Ω
.
Measurement:
Disassemble the three-phase cable, and turn breaker to ON.
Measure the insulation resistance between output terminal and
engine frame.
It is possible for electricity leakage or fire hazard when the
insulation resistance is lower than 1M
Ω
. Clean and dry output terminal, breaker, and cable.
Consult with dealer for any question.
(5) Check battery proportion
The engine may not start due to the battery leakage. If that happens, you should measure the
proportion of battery electrolyte.
(Refer to 5.4.2 for the relation between battery and battery electrolyte proportion. )
7.1.3 Check for every 500 Hrs
Check for every 500 Hrs should cooperate with check for every 250 Hrs.
(1) Check spring gasket of fuel filter.
a. Screw off the fuel filter by filter wrench, and take off the spring gasket.
b. Clean filter and daub slim engine oil on filter surface, then install it.
Don't screw so tight.
c. Eliminate the air of fuel pipe, after replace spring gasket.
(Refer to the engine operation manual for the manufacturer and model
of spring gasket)
(2) Clean radiator
Please clean the radiator orifice by using steam or high-pressure air.
Cleaning operation with high pressure air should be done beyond1.5M,
in order not to damage the fan and pipe. Besides, take off the electric fan,
avoid it being connected with steam or high pressure water directly.
(3) Check circuit terminal and connection terminal
Check if there is rust and burnout in main and vice circuitry
