5.5.2 Change Engine Oil Filter
[At 50 hours for the first change and every 500 hours thereafter]
＜
Procedure
＞
①
When installing a new oil filter
“

”
, spread oil over
the packing
“
2
”
, and then screw it in. When the
packing touches the sealing surface, further tighten
the filter by approximately two-thirds turn with a
filter wrench.
②
After the oil filter
“

”
is assembled, check if there are
any oil leaks during operation. (See 5.3)
5.5.3 Check Insulation Resistance
[Every 2 months or every 250 hours]
When the generator has not been operated for a long time or rainwater has got inside the machine, be
sure to measure the insulation resistance. If it is reduced to lower than 1M
Ω , it could cause an electrical
leakage or a fire. Dry up the generator main unit until the resistance exceeds 1M
Ω
, then start operating.
Make sure that no foreign matters are meshed between rotor and stator etc, and also check for dust or
dirt because these things such as humidity, oil and dust sticking to the unit deteriorate the insulation.
After cleaning the main part of the generator as disposal of insulated recovery, there is a method of put-
ting an electric bulb into the inside of the main part of the generator main unit , or sending a hot wind
into an inside. Under the present circumstances, it is more effective if the whole main part of the gen-
erator main unit is dried in the state where it covered with the sheet. However, please let the bending
way and average dry local overheating as notes. Coil surface temperature should not exceed 80
～ 90 ℃ .
Even if it carries out the above disposal, when you do not recover, contact us directly or our distributors.

①
Remove the load side cable from the output terminal
board.
②
Remove the AVR connector
“

inside the machine
control panel.
③
Switch ON the circuit breaker
“

”
, measure each
insulation resistance between the terminals U. V. W
terminal and bonnet.
④
If insulation resistance when measured with a 500V
megger tester is over 1M
Ω
, it is good.
