Handling the Hose Unlocking Tool [03047090-xx]
► Use the pipe-shaped tool (1) to open the unlocking ring.
► Carefully pull the hose out of the compressed air connection. The diagram shows the removal of a
dummy plug (2), not a hose.

Replacing the X Trailing Cable
Parts, Equipment and Tools
▪ X trailing cable (see above)
▪ Hose unlocking tool [03047090-xx]
▪ Pipe/hose cutters [00381443-xx]
▪ If required, assembly instructions for the "vacuum pump" [00196845-xx]
▪ Sealing varnish Loctite 241 [02101037-xx]
▪ Edding marker, white [00382740-xx]
▪ Help of second person, if needed
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..." [ ➙ 89].
Due to the poor access to the pneumatic distributor, we
recommend using an unlocking tool.
With the help of the hose unlocking tool [03047090-xx]
you can open the unlocking ring (blue here) for the com-
pressed air connection. This enables you to remove both
the hoses and the dummy plugs (additional tool "Unlock-
ing tool for QSC-10H" [03051853-xx]).
NOTICE
Vacuum pump
► When a vacuum pump is fitted, also observe the assembly instructions "Vacuum pump X-
Series S, SX4/DX4" [00196845-xx].

Pneumatics Sy stem - Shutting off the Compressed Air Supply
Loosening the trailing cable on the machine side
Disabling the compressed air supply
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. Hold a cloth underneath to capture any escaping
oil.
► All manometers must be set to zero.
► 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.

1. Fastening screws 5x (not sealed)
2. Fastening screws 2x (with sealing varnish)
► Dismantle the board cover. You need to loosen the
fastening screws for this at(1) and (2).
CAUTION!
To avoid short circuits, only dismantle the cover when the
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
on.
► Loosen the two screws (5) fastening the trailing cable
clamp (6).
► Pull the hoses off the gantry distributor. You may
want to mark their positions, to make clear assign-
ment easier later on.
WARNING!
Risk of injury to hands
Use the "hose unlocking tool" for this [03047090-xx].
