TOPPING UP THE COMPRESSOR
OIL
1. Stop the compressor. Wait a few
minutes until the pressure is released
through the automatic blow-down
valve. Make sure that all pressure is
released by loosening the filler plug (2)
one turn.
2. Wait a few minutes until the oil level is
constant.
3. Remove the filler plug (2) and top up
with oil until the pointer of the oil level
gauge (1) is in the upper part of the
green area.
4. Reinstall and tighten the filler plug (2).
COMPRESSOR OIL AND OIL
FILTER CHANGE
The quality and the temperature of the oil
determine the oil change interval.
The prescribed interval is based on normal
operating conditions and an oil
temperature of up to 100 °C (212 °F) (see
section Preventive maintenance
schedule for the compressor).
When operating in high ambient
temperatures, in very dusty or high
humidity conditions, it is recommended to
change the oil more frequently.
1. Run the compressor until warm. Close
the outlet valve(s) (3) and stop the
compressor. Wait until the pressure is
released through the automatic blow-
down valve. Unscrew the oil filler plug
(2) one turn. This uncovers a vent hole,
which permits any pressure in the
system to escape.
2. Drain the compressor oil by removing
all relevant drain plugs (4). Catch the oil
in a drain pan. Screw out the filler plug
(2) to speed up draining. After draining,
place and tighten the drain plugs (4).
3. Remove the oil filter (1), e.g. by means
of a special tool. Catch the oil in a drain
pan.
4. Clean the filter seat on the manifold,
taking care that no dirt drops into the
system. Oil the gasket of the new filter
element. Screw it into place until the
gasket contacts its seat, then tighten one
half turn only.
In this case, contact Atlas
Copco.
