WARNING: Risk of injury!
Always adhere to the prescribed operating method described below for all
maintenance work. Never omit a single safety step!
Otherwise you will risk injury from restarting, electric shock or parts which
may fly off.
Prior to all maintenance work:
1. Switch off the compressor using the OFF button.
2. Actuate emergency-stop switch/button.
3. Open mains disconnection device and secure against unintentional
switch on by means of a padlock.
4. Fix a warning label to the control and fill in the name of the person
responsible who is authorized to switch on the maschine again.
5. Check to ensure that all machine elements are definitely currentless.
6. Prior to starting work let cool down all hot components of the compressor
to 122°F.
7. Separate the compressor from the compressed air network by closing
the ball valve at the compressed air outlet.
8. Vent the compressor.
To this effect open the safety valve on the combined compressed air-oil
receiver as follows:
–
Turn the knurled nut counterclockwise until you can feel a resilient
resistance.
–
Turn the knurled nut a little further.
Any possibly existing air will escape.
The system pressure gauge will indicate a pressure of 0 psig.
–
Once the residual air has completely escaped from the system, firmly
retighten the knurled nut.
9. Remove all safety cladding necessary to perform the maintenance work.
Once the maintenance work has been concluded:
10. Reattach all removed safety cladding.
11. Open the ball valve at the compressed air outlet.
12. Prior to switching on again, check whether anyone else is working on the
compressor.
13. Remove warning sign not until then and release mains disconnecting
device.
14. Unlock emergency-stop switch/button.
