On ZR 110 up to ZR 275 and ZT 110 up to ZT 275, check that the oil level is in the
middle of sight-glass (SG) after stopping (at longer standstill the level may rise in the
sight-glass).
Top up, if necessary.

7.3

Safety valves

Testing

The valves can be tested on a separate compressed air line. If a valve does not open at the
pressure specified in 

Settings of safety valves

, consult Atlas Copco.

Never run the compressor without safety valves.
No adjustments are allowed.

7.4

Coolers

Testing

The coolers must be serviced regularly; refer to
