Version 1.1
Open the left side panel. Remove the oil
filter (1) using a special Oil Filter Wrench.
Drain the oil from the filter into a dedica-
ted vessel and clean the filter seat.
Oil the gasket of the new oil filter and screw
it into place. Only tighten oil filter by hand.
Start up the compressor.
Stop the compressor and let it run idly for
several minutes in order for the oil to cir-
culate and air to be extracted from the oil
system. Wait several minutes until the oil
settles and the inner pressure drops.
If necessary, unscrew the fill plug and add
oil until it is level with the middle of the
sight glass.
Place the fill plug into its initial position and
tighten it.
5.5 Replacing air filter
The air filter (1) is attached to
the compressor’s intake valve.
In order to replace it, open the front
side panel, loosen the clamp (2) secur-
ing the filter. Remove the contaminat -
ed filter, and detach the clamp from it.
Set the new filter in its place and fit into
place with the clamp.
