Important
Do not mix oils of different specifications.
Machines which are delivered without oil must first
be filled to the max. mark in the pressure reservoir
sight glass (see also chapters 9.4 and 9.15)
Check the oil level as follows:
• Stop the compressor, with the stop button.
• Wait at least 5 minutes for the oil to settle and for
the air to disperse
• The oil level is checked with the help of the
transparent plastic tube at the pressure reservoir
(- 2 - Fig. 14) after every stop and at regular
intervals. If required, top up oil
• The oil level must be between the maximum level
(- 3 - Fig. 14) and minimum level (- 4 - Fig. 14)
marked on the oil reservoir.
