1. Top up with fuel at the end of each day's operation to prevent conden-
sate from contaminating the fuel.
2. More frequently when operating in high ambient temperatures.
3. More frequently when operating in a dusty atmosphere.
4. Screw the cap of the safety valve anti-clockwise using a glove. After
testing, retighten the cap by hand.
5. Use ball bearing grease for the wheel bearings.
6. Drain until clean fuel flows from the drain cock.
7. Some oil brands launch special oil types for screw compressors allow-
ing a longer oil change interval. Consult Atlas Copco.
8. Use Atlas Copco oil filters, with by-pass valve, as specified in the parts
list.
9. Replace the fuel filters regularly. Gummed or clogged filters mean fuel
starvation and reduced engine performance. The quality of the fuel
determines the frequency of filter renewal.
10.Replace the element if pressure drop exceeds 12 psi (0.8 bar).

CARE
Charging
Before handling batteries, read the chapter 'Safety precautions' and act ac-
cordingly. A Service Bulletin (ASB) dealing elaborately with batteries and
due care is available on request.
Maintenance
Keep the battery clean and dry, the electrolyte level at 0.4 to 0.6 inch (10
to 15 mm) above the plates or at the indicated level (top up with distilled
water only). Cover the terminals lightly with petroleum jelly.
S
TORAGE
Regularly run the compressor until it is warmed up. Load and unload the
compressor a few times. Keep the outlet valve closed after stopping.
If the compressor is going to be stored without running from time to time,
protective measures must be taken as described in a separate Service Bul-
letin (ASB), which may be obtained on request.

KITS
Atlas Copco service kits offer you all the benefits of genuine Atlas Copco
parts. Kits provide for the right parts for maintenance activities on specific
parts of your compressor such as the oil separator, the unloading valve, the
minimum pressure valve, the regulating valve and the oil stop valve. The
use of service kits minimises downtime and keeps your maintenance budg-
et low. The order numbers and the contents of the service kits can be found
in the section "Service kits" in the parts list.
Contact your Atlas Copco representative for more information.

manual for oil specifications, viscosity recommendations and oil change
intervals.

FILTERS
1. Run the compressor until it is warmed up. 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 one turn. This
uncovers a vent-hole, which permits any pressure in the system to
escape.
2. Remove the oil filters (by means of an oil filter spanner).
3. Clean the filter seats on the manifold, taking care that no dirt drops into
the system. Oil the gaskets of the new oil filters. Screw the filters into
place until the gaskets contact their seats, then tighten one half turn
only.
4. Drain the oil by removing all these drain plugs: air receiver/oil separa-
tor, oil cooler, oil stop valve, check valve and gearbox. Reinstall and
tighten the plugs, using new gaskets, after draining.
5. Fill the air receiver until the level reaches the screw thread in the filler
pipe. Take care that no dirt drops into the system. Reinstall and tighten
the filler plug.
6. Run the compressor at no-load for a few minutes to circulate the oil.
Load the compressor and let it run at maximum speed and normal
working pressure until the thermostatic by-pass valve of the oil cooler
has opened (approx. 185 °F (85 °C) (TG)). Close the air outlet valves.
Stop and let the compressor depressurize as described in step 1. Add
oil until the level shows in the top of the sight glass (SG). Reinstall and
tighten the filler plug.
7. Start the compressor and let it run at maximum speed and normal
working pressure. Close the air outlet valve and stop the compressor.
Let the compressor depressurize as described in step 1. Check the oil
level, which must show in the sight glass; if it does not, repeat steps 6
and 7.
