6.5.1 CHECK
The oil level should be checked daily.
1.
Shut down the compressor (or check before the compressor is turned on).
2.
Wait two minutes after the compressor stops to allow the pressure to be relieved and the oil to settle.
3.
Observe the oil level in the fluid sightglass. The fluid sightglass should be full.
4.
While the compressor is running, the oil should be visible in the sightglass and the compressor not
running hot.
6.5.2 FILL
Oil must be added to the compressor if the oil level is below the sightglass when the compressor is running.
1.
Follow
procedures.
2.
Verify that compressor has little to no air pressure prior to removal of component parts.
3.
Clean any dirt from around the oil fill cap.
4.
Loosen the cap to make sure any remaining pressure is relieved through the vent hole, then remove.
5.
Add oil to the edge of the oil fill port.
6.
Replace cap and tighten securely.
6.5.3 CHANGE
Change the compressor oil as indicated by
or if fault A:4805 is shown on the
microprocessor.
REMOVE OLD LUBRICANT
1.
Follow
procedures.
2.
Remove the drain plug from the end of the drain line at the bottom of the sump tank.
3.
Open the drain valve and allow all oil to drain. Discard in an approved manner.
4.
Remove any remaining oil by splitting the discharge pipe at the compressor unit.
ADD NEW LUBRICANT
1.
Clean any dirt from around the oil fill cap.
2.
Loosen the cap to make sure any remaining pressure is relieved through the vent hole, then remove.
3.
Add oil to the edge of the oil fill port.
4.
Replace cap and tighten securely.
6.5.4 CONVERT
When converting to a different type of oil in the compressor, use the following procedures to ensure the
different oil types do not mix.
REMOVE OLD LUBRICANT
1.
Follow
procedures.
2.
Remove the drain plug from the end of the drain line at the bottom of the sump tank.
3.
Open the drain valve and allow all oil to drain. Discard in an approved manner.
4.
Remove any remaining oil by splitting the discharge pipe at the compressor unit.
5.
Remove oil filter element.
FLUSH COMPRESSOR
1.
Pour as much flush lubricant into the inlet as was removed from the compressor.
2.
Add flush lubricant to the sump tank to maximum fill level.
3.
Install the oil filter element and jog compressor.
4.
Run the compressor at normal operating conditions for two days to two weeks.
5.
Draw an oil sample to check the appearance of the flush lubricant. The sample should be clear. If
not, drain flush lubricant and refill. Run for two more days. When the sample is clear, proceed to the
next step.
ADD NEW LUBRICANT
1.
Drain flush lubricant.
