 Maintenance

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-on lock.

6.8  Connection of oil level regulator

The connection "O" is provided for installing an oil level regulator. A corresponding adapter must be 
obtained from the trade.
