Change compressor oil
At 300 hours for the first change and at every 500 hours thereafter
For prevention of fire caused due to deteriorated oil separator, in principle change of compressor
oil is to be performed in accordance with the schedule mentioned in the regular maintenance
table.
However, it is heavily influenced by operation conditions and environmental conditions. If it has
been found more dirty and corrupted, it should be changed.
If machine is continuously operated in such bad conditions, it could damage bearings and
degraded oil sticks oil separator to cause accumulated oxidation heat of reaction to lead oil
separator fire. For this reason, regular maintenance work should be done surely and perfectly.
Conduct changing compressor oil after checking machine stoppage for about 2-3 minutes and
dropping pressure of separator receiver tank to zero.
<Procedures>
1.
After the machine has stopped and pressure inside
the separator receiver tank has been completely
released as much time passed, remove the oil filler
cap [A] and open the drain valve [B] to drain the
residual oil. Further, open the drain valve [E] after
removing oil cooler drain plug [D] and drain the oil
accumulated in the cooler.
2.
After draining compressor oil, surely retighten drain
valve [B] and [E].
3.
Fill the tank with new compressor oil up to the height
indicated by the dotted line (Fuel Limit). Then, close
filler cap [A]. Inspect O-ring [C] of filler cap [A]. and
replace it with a new one if any hardening or damage
is found.
4.
After starting operation, check and confirm that oil
level is within red lines of oil revel gauge.
5.
Repeat the process 1
to 4 if oil level is out of red lines
range.
Mixture of different brands compressor oil could cause an increase of viscosity and
make compressor oil sticky. In the worst case, it could cause sticking trouble of
compressor air-end “Compressor air-end will not turn”. Also repairing of such air-end
needs expensive cost. Therefore, be sure to avoid mixing different brands oil. In case
compressor oil brand in use has to be unavoidably changed, it is absolutely necessary
to completely clean up the interior of compressor air-end. In such a case, contact
“AIRMAN” dealer or us directly.
Follow the designated regulations to dispose of compressor oil.
