NOTICE

Vacuum pump

► When a vacuum pump is fitted, also observe the assembly instructions "Vacuum pump X-

Series S, SX4/DX4" [00196845-xx].

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.

► Carefully remove the trailing cable from the machine. You might need to enlist the help of a second

person.

► 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 connectors from the gantry interface.

► Loosen the screws fastening the upper end of the

trailing cable.

► Dismantle the cover (1) on the trailing cable

interface (2).

Installation

► Installation is performed by following the above instructions in the reverse order. Also observe the

following instructions:

CAUTION

Always handle the trailing cable with care

► 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.

► For production reasons, the new trailing cable is supplied with a holder. This new holder

can be dismantled before installation and the holder already in the machine can be used

again.

► If you use the new holder, you will need to dismantle all attached items (boards etc.) from

the old holder and attach them to the new holder.

► 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.

► Check that the power track chain runs parallel to the machine base. Move the gantry back

and forth.

► If it is difficult to push the hoses onto the tubes, moisten these first with white spirits or iso-

propanol.

► Secure with screws with Loctite 241.
