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.
The oil level must lie between the "maximum oil level" and "minimum oil level" marks on the oil reservoir.
If required, top up oil. Use Gardner Denver oil only.
Close the oil filler cap firmly.
