► Loosen the six screws fastening the cover (1) and
then remove the cover.
► Mark the positions of the hoses on both sides of the
couplings (1), so that these can be easily assigned
later on.
► Disconnect the hoses from the couplings.
► Mark the positions of the connectors (2) on the gantry
interface (3), so that these can be easily assigned lat-
er on.
► Unplug the connector from the gantry interface and
unthread the cable.

machine is switched off!
► Loosen the two screws (2) fastening the downholder
(1) and then remove the downholder.
► Loosen the cable clamp (3).
► Unplug the connectors (4). You may want to mark
their positions, to make clear assignment easier later

following instructions:
► Loosen the two screws fastening the holder (1).
► Loosen the two screws fastening the holder (2).
CAUTION
Installation instructions
► If a vacuum pump is fitted, also observe the relevant assembly instructions [00196845-xx].
► Always handle the new trailing cable with care.
► You might need to enlist the help of a second person.
► Make sure that the flat ribbon cable and the pneumatic hoses are not rubbed against any
parts or folded. Look out for sharp edges.
► Prepare the trailing cable. Place the old and new trailing cables next to one another and
match the length of the new trailing cable hose to the old one.
You might find it helpful to mark the new hoses and connectors in the same way as the old
ones.
► If hose ends were damaged during removal, cut these with hose cutters.
► Clean the trailing cable contact surface on the machine base with a dry cloth.
► Carefully insert the new trailing cable into the prescribed position. Make sure you do not fold
or twist the trailing cable.
► Make sure that the power track chain runs parallel to the gantry. Move the head mount back
and forth to check this.
► Secure with screws with Loctite 241.
► Fit the board cover. Make sure that you do not cause a short circuit.
