Regularly check the oil level. To do so:
1. Press the stop button on the control panel.
2. A few minutes after stopping, the oil level should be between the oil filler neck (FC) and the
top of the sight glass (Gl).
3. If the oil level is too low, push the emergency stop button to avoid the compressor to start
unexpectedly.
4. Next, close the air outlet valve and open the manual drain valve (Dm) until the air system
between oil separator/air receiver vessel and outlet valve is fully depressurized. See section
Condensate system
5. Unscrew oil filler plug (FC) one turn to permit any pressure left in the system to escape. Wait
a few minutes.
6. Remove the plug and add oil until the level reaches the filler opening.
7. Fit and tighten the plug (FC).
Unlock the emergency stop button, select the STOP icon and press reset before starting.
