Open the front panel and turn the fill
plug (2) one revolution in order vent
system pressure.
Remove the fill 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. Refit and tighten the drain
valve plug and the fill plug.
Open the front 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 fil-
ter by hand. Start up the compressor.
Stop the compressor and let it run idly
for several minutes in order for the
oil to circulate and air to be extracted
from the oil system. Wait several min-
utes 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.
