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.
