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
1
Check oil level on a daily basis. In or-
der 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 al-
ways be visible in the sight glass. If no
oil is visible in the sight glass, the oil lev-
el is low and needs to be topped up. Us-
ing belt tension gauge, check the tensile
force of the compressor belts.
