4.5.1 Engine Oil And Oil Filter Change
Consult also the Engine Operators Manual for oil and oil
filter
(1) change intervals.
(2) oil types.
4.5.2 Compressor Oil And Oil Filter
Change
The quality and the temperature of the oil determine the oil
change interval.
The prescribed interval (See section 4.2) is based on an oil
temperature of up to 100ºC (212ºF) and normal operating
conditions.
When operating in high ambient temperatures, in very
dusty or high humidity conditions, it is recommended to
change the oil more frequently.
+
In this case, contact Atlas Copco.
1 Run the compressor until warm. Close the outlet
valve(s) and stop the compressor. Wait until the
pressure is released through the automatic blow-down
valve. Unscrew the oil filler plug (FP) one turn. This
uncovers a vent hole, which permits any pressure in
the system to escape.
2 Drain the oil by removing all drain plugs. Drain plugs
are located at the oil tank, discharge manifold, and oil
injection manifold. Catch the oil in a drain pan. Screw
out the filler plug to speed up draining. Tighten the
plugs after draining.
3 Remove the oil filter (OFc), 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.

4.6 Cleaning Coolers

Keep the coolers clean to maintain the cooling efficiency. Front
cooler baffle is removable for access by unscrewing 4 bolts.
When cleaning by air jet, blow air through the cooler in reverse
direction of normal flow.
If the dirt is oily, wash the coolers with degreaser or a cleansing
agent.
A spray gun should preferably be used to apply the solvent to
the fins. Rinse the blocks by means of a water jet max. 100 psi
at 2 inch distance after a soaking-in period. Steam cleaning
may also be applied.

4.7 Battery Care

+
An ASB (Service Bulletin) dealing elaborately with batteries and
due care is available on request.
If the battery is still dry, it must be activated as described in
point 4.7.1.
The battery must be in operation within 2 months from being
activated; if not, it needs to be recharged first.
4.7.1 Electrolyte
Electrolyte in batteries is a sulphuric acid solution in distilled
water.
Fill the air receiver until the pointer of the oil level gauge
(OLG) registers in the upper extremity of the green range.
Take care that no dirt drops into the system. Reinstall and
tighten the filler plug.
Run the unit at no load for a few minutes to circulate the oil
and to evacuate the air trapped in the oil system.
Stop the compressor. Let the oil settle for a few minutes.
Check that the pressure is released by opening an air outlet
valve (AV). Screw out filler plug (FP) and add oil until the
pointer of the oil level gauge (OLG) again registers in the
upper extremity of the green range. Reinstall and tighten
the filler plug.
Never add more oil. Overfilling results in oil
consumption.
Remove any dirt from the coolers with a fiber brush.
Never use a wire brush or metal objects.
Protect the electrical and controlling equipment, air
filters etc. against penetration of moisture.
To avoid damaging the coolers, angle between
waterjet and coolers should be approx. 90º.
Never leave spilled liquids such as fuel, oil, water and
cleansing agents in or around the compressor.
Before handling batteries, read the relevant safety
precautions and act accordingly.
Read the safety instructions carefully
