Open the front panel and turn the ll plug
(2) one revolution in order vent system
pressure.
Remove the ll plug. Remove plug from the
drain valve (1) at the bottom of the Air-Oil
separation tank.
Drain the oil into a dedicated vessel from
the separator tank after opening the drain
valve. Fill the Air-Oil separation tank with oil
until it is level with the middle of the sight
glass. Ret and tighten the drain valve plug
and the ll plug.
Open the right side panel. Remove the oil
lter (1) using a special Oil Filter Wrench.
Drain the oil from the lter into a dedica-
ted vessel and clean the lter seat. Oil the
gasket of the new oil lter and screw it into
place. Only tighten oil lter 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 ne-
cessary, unscrew the ll plug and add oil
until it is level with the middle of the sight
glass. Place the ll plug into its initial positi-
on and tighten it.
