5.6.5 Change Compressor Oil
[At 300 hours for the first change and at every 500 hours thereafter]
Refilling of compressor oil
When you refill the separator receiver tank with compressor oil,
stop the engine, and make sure that the pressure gauge indi-
cates 0MPa and there is no residual pressure in it, and then
gradually loosen the oil filler cap for refilling oil.
Note residual pressure in the receiver tank could force both ex-
tremely hot compressed air and oil to jet out and you may be
scalded or seriously injured.
Even continuous oil replenishment cannot improve its deterio-
rated condition. Be sure to change the oil completely at every
scheduled interval.
Do not mix it with other brand oil, or it will cause poor perform-
ance and shorten the life of the compressor oil. (But fresh com-
pressor oil could accept a mixture of small amount of different
brands.)
Running the unit with old and deteriorated compressor oil will
cause damage to bearings, or serious accident like ignition in a
separator receiver tank. Be sure to change the oil completely at
every scheduled interval.
Follow the designated regulations to dispose of compressor oil.

, pipes
and oil cooler. If wasted oil is left in the unit, this residual
oil will greatly shorten the life of the newly replenished oil.
④
Be sure to close drain valve

after the wasted oil is
completely discharged.
⑤
Fill the designated quantity of new oil into the oil filler port.

in its place while paying
attention not to let dust get in the tank.

Start the engine for a short while, then replenish the oil to
fill shortage. Repeat this procedure for 2 to 3 times to check
if the oil level has reached its appropriate point. Be careful
not to overfill the oil.
