Check the oil level as follows:

Shut off the compressor with the STOP button.

Wait at least 5 minutes until the oil has settled, i.e.
until the air has bubbled out.

The oil level should be checked at each pause in
operation and at regular intervals using the oil
level gauge on the pressure reservoir (-2- Fig. 14).

The oil level must lie between the "maximum oil
level" (-3- Fig. 14) and "minimum oil level"

If required, top up oil. Use Gardner Denver oil only.
