Beyond 6000 working hours, compressor maintenance consists in alternating M-2 and M-3

every 2000 hours of running time. Performance of daily, weekly, monthly and annual servic-

ing does not annul the need for maintenance in terms of operating hours.

5.2 Checking oil level

Check oil level on a daily basis. In order to access the oil level, stop the compressor and

remove the front side panel.

The oil level in the compressor should be checked visually with the oil level glass (1) when

the compressor has stopped.

The surface of the oil must always be visible in the sight glass.

If no oil is visible in the sight glass, the oil level is low and needs to be topped up. Using belt

tension gauge, check the tensile force of the compressor belts.
