FILLING OIL RESERVOIR
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
1.
Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2.
Disconnect, lockout and tagout the power supply to the starter.
3.
Wipe away all dirt around the oil filler plug.
4.
Remove the oil filler plug and add oil as required to return the oil level to the center of the green
range on the gauge.
5.
Install the oil filler plug and operate the unit for about a minute allowing oil to fill all areas of the
system. Check for leaks.
6.
Shut down unit, allowing the oil to settle, and be certain all pressure is relieved.
7.
Add oil, if necessary, to bring level to the center of the green range on the gauge.
On unloaded operation and after shutdown some oil will drain back into the oil reservoir and the oil level
gauge will read "FULL." DO NOT DRAIN OIL TO CORRECT. On the next start, oil will again fill the
system and the gauge will indicate operating at the proper level. DO NOT OVERFILL as oil carryover will
result. The quantity of oil required to raise the oil level from "ADD" to "FULL" is shown in Figure 5-8.
Repeated addition of oil between changes may indicate excessive oil carryover and should be
investigated.
Use only CLEAN containers and funnels so no dirt enters the reservoir. Provide for clean storage of oils.
Changing the oil will be of little benefit if done in a careless manner.
Excessive oil carry-over can damage equipment. Never fill oil reservoir above
the "FULL" marker.
