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.
7.3 Spare part recommendation
Available spare parts and accessories can be found on our compressor selection tool under
vap.bock.de as well as at bockshop.bock.de.
Only use genuine Bock spare parts!

7.5 Decommissioning
Close the shut-off valves on the compressor. CO
blown off into the environment. It is essential to ensure good ventilation or conduct the CO
outdoors to avoid danger of suffocation. When releasing CO
oil from exiting with it. If the compressor is unpressurized, remove the piping on the pressure- and
suction-side (e.g. dismantling of the shut-off valve, etc.) and remove the compressor using an appro-
priate hoist. Dispose of the oil inside in accordance with the applicable national regulations.
When decommissioning the compressor (eg. for service or replacement of the compressor) larger
amounts of CO
in the oil can be set free. If the decompression of the compressor is not sufficient

enough, closed shut-off valves may lead to intolerable excessive pressure. For this reason the suction
side (LP) and the high pressure side (HP) of the compressor have to be secured by decompression
valves.
