Maintenance

7.2 Work to be carried out

In order to guarantee optimum operational reliability and service life of the compressor,

we

recommend

carrying out servicing and inspection work at regular intervals:

Oil change:

-

not mandatory for factory-produced series systems.

-

for field installations or when operating near the application limit: for the first time after 100
to 200 operating hours, then approx. every 3 years or 10,000 - 12,000 operating hours.
Dispose of used oil according to the regulations; observe national regulations.

Annual checks:

Oil level, leak tightness, running noises, pressures, temperatures, function of

auxiliary devices such as oil sump heater, pressure switch.

WARNING

Before starting any work on the compressor:

Switch off the compressor and secure it to prevent a restart.
Relieve compressor of system pressure.

Prevent air from infiltrating the system!

After maintenance has been performed:

  Connect safety switch.
  Evacuate compressor.
  Release switch lock.
