DANGER
Observe User Manual
► Please observe the safety instructions in the user manual for all work!
CAUTION
Switch off the compressed air supply.
When working on the pneumatic system, always disconnect the machine from the com-
pressed air supply.
CAUTION
Use the correct blanking plugs
► Only use blanking plugs in the machine which match the manufacturer's compressed
air connection. A tight fit cannot be guaranteed for other blanking plugs.
► We recommend the use of blanking plugs made by Festo.

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).

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].
Fig.83: Disabling the compressed air supply
CAUTION!
Switch off the compressed air supply.
When working on the pneumatic system, always
switch off the compressed air supply.
.
► Push the lever (1) for the compressed air supply
back, until it is positioned horizontally.
► Open the screw (2) on the inlet filter to vent the
system. Hold a cloth underneath to capture any
escaping oil.
► All pressure gauges must be set to zero.
► Disconnect the machine from the compressed air
supply.

► Loosen the screws(2) fastening the side
cover(1) at location 2 and remove the side cover.
