3.1.4.4 Oil Change

1. Run the compressor until it is warm then shut it down.
2. (See Figure 3-5). Remove the cap (1) from the oil filler neck.
3. Drain oil while it is still warm by means of the oil drain plug.
Replace the oil filter every oil change. Failure to do so will cause the filter to clog and the bypass valve to
open resulting in unfiltered oil being circulated and possible damage to the compressor.
4. (See Figure 3-6). Remove the two bolts (1) with a 13 mm wrench. Remove the oil filter cover (2)
5. (See Figure 3-7). Remove the oil filter (1) from the rubber gasket at the cover.
6. Mount a new filter element (P/N N25326) and replace and fasten oil filter cover.
7. Slowly pour new oil through the oil filler neck until the level reaches the maximum mark on the
sight gauge.
8. Wait a few minutes and adjust the oil level if necessary before putting the unit into operation.
3.1.5 Venting the Oil Pump
(See Figure 3-7) If no or low oil pressure builds up after starting the unit, especially after maintenance
or repair or if the compressor has been run the wrong direction, venting the oil pump may be necessary.
1. Run the compressor with all condensate drains open to avoid building up pressure.
2. Unscrew Screw Cap (2) and Plug and wait until Oil comes out free of air bubbles.
3. Retighten Plug and Screw Cap.
4. Check Oil Level (See Paragraph 3.1.4.2) and replace oil as necessary.
3.1.5.1 Gas Intake System
In order for these compressors to work satisfactorily, it is absolutely essential to supply the medium at a
constant pressure. Therefore a pressure reducer in the intake line is necessary if the supply pressure is
above atmospheric pressure or fluctuating. An intake expansion tank between the pressure reducer and
the compressor may also be necessary to compensate for the pressure surges caused by the 1st stage pis-
ton.
