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 transparent plastic tube
on the pressure reservoir (- 2 - Fig. 13).

The oil level must lie
between the “maximum oil level” (- 3 - Fig. 13) and “minimum oil level”
(- 4 - Fig. 13) marks on the oil container.

If required, top up oil. Use Gardner Denver oil only.

Close the oil filler cap (-1- Fig. 13) firmly.
