Figure 5-2 – APPROXIMATE OIL SYSTEM CAPACITIES
ADDITION OF OIL BETWEEN CHANGES must be made when the oil level is below the center of the
lower sight gauge as read while the unit is completely off and blown down, and the foam has settled out.
1. Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2.
Disconnect, tag and lockout 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 bottom of the sight
gauge.
5.
Install oil filler plug, run and check for leaks.
DO NOT OVERFILL (you should see oil slightly above the full line after running fully loaded and then
shutting down the machine and allowing the foam to settle out). The quantity required to raise the oil
level from “ADD” to “FULL” is shown in Figure 5-2, page 47. Repeated addition of oil between oil
changes may indicate excessive oil carry-over and should be investigated.
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, tag and lockout power
supply to the starter before removing valves, caps, plugs, fittings, bolts and
filters.
Compressor, air/oil reservoir, separator chamber and all piping and tubing may
be at high temperature during and after operation.
