Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation. Observe the instructions in section 1.2 "Preparatory Work..." [}15].
► Remove the four screws fastening the cover fan. Make sure that the washers are not lost. You
may want to mark the direction of fan operation, to make clear assignment easier later on.

CAUTION
Switch off the compressed air supply.
When working on the pneumatic system, always disconnect the machine from the com-
pressed air supply.

5.2 Sealing the Pneumatic Screwed Connections
NOTICE
Sealing the pneumatic screwed connections
If pneumatic screwed connections are loosened, these will need to be sealed again after-
wards. Always use the same sealing technique as was used before they were removed.
The following sealing techniques are available:
► Sealing ring (rubber or plastic)
These are either supplied or you can use the ones used before. Check the condition of
used sealing rings for damage.
► Sealant
There are several variants of this:
Loctite 567 [03097172-xx] and Loctite 55 [03092492-xx]
After loosening the pneumatic screwed connection, clean the screwed thread and seal
it with Loctite. The sealing thread for Loctite 55 must be wound on in the direction of
the screwed thread.
There may also already be a sealant on the screwed thread.
5.3 Setting the Compressed Air Controller for Machine
Components
► Make sure that the compressed air controller(1)
for machine components is set to 5.1bar(2).
