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.
