Pneumatic System - Overview
The pneumatic system is located at locations 1, 3 and 4, behind the side covers.
CAUTION
Switch off the compressed air supply.
When working on the pneumatic system, always disconnect the machine from the compressed
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.

NOTICE
Sealing the Screwed Connections
If compressed air 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.
There are several different sealing techniques:
► Sealing ring (rubber or plastic)
These are either supplied or you can use the ones used before. Check the condition of the
sealing rings for damage.
► Sealant
There are several variants of this:
Loctite 567 [03097172-xx] and Loctite 55 [03092492-xx] – after loosening the 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.
Most tasks performed on the pneumatic system require
that you dismantle the lower side cover.
► To do this, loosen the 6 screws fastening the side
cover in the order (1) to (4) and remove these. While
unscrewing, always hold on to the side cover, to pre-
vent it falling off.
► Carefully pull out the side cover.

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..." [ ➙ 12].
► To do this, loosen the screws fastening the side cover and remove these. (See "3.4.3 Dismantling
the Lower Side Cover" [ ➙ 64])
► Loosen the screwed clamps at the top and bottom of the pressure regulator.
► Carefully remove the pressure regulator.

CAUTION!
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 sys-
tem.
► All manometers must be set to zero.
