 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.
