Regular maintenance work

Checking the safety 
valve

Check:

After approx. 3,000 operating hours, however, at least once a year.

Check safety valve by opening the screw plug (1).

Fig. 5.9: Check safety valve

Nozzle with dirt catch

Change: 

After 3,000 operating hours, however, no later than after one year.

Switch off the compressor using the OFF button.

Caution: Risk of injury!

Danger of burning due to hot oil!
Take extreme care when checking the safety valve with the compressor run-
ning taking all safety measures into consideration.
Always wear safety gloves!
A hot air-oil mixture escapes when opening!

Open the threaded plug 
(1) counterclockwise. The 
air-oil mixture escapes.

Tighten the threaded plug 
by turning clockwise.

Attention!

If the prescribed maintenance intervals are not complied with, the residual oil 
content in the compressed air rises considerably.

Caution: Risk of injury!

Press Emergency Stop button, open mains disconnection device and secure 
against unintentional switch on by means of a padlock.
