11.7 Replacing the Articulated Joint on the Short-Stroke Cylinder [03000518-xx]
260 Service Manual SIPLACE TX Series 06/2017
Fig.360: Plastic caps
From the bottom side of the cutter you have easy ac-
cess to the plastic cap.
► Remove the plastic caps(1) over the fastening
screws on both sides of the movable blade.
► Remove the two screws.
Fig.361: Movable blade
► Loosen the movable blade(2) from the piston(1)
of the short-stroke cylinder.
CAUTION!
Risk of injury!
There is a risk of injuring yourself on the cutting
edge of the blades.
.
Fig.362: Removing the articulated joint
► Remove the circlip (1).
► Push the piston rod a little into the short-stroke
cylinder and rotate the articulated joint by 90de-
grees.
► Push the bolt(2) out of the articulated joint.
► Unscrew the remaining articulated joint ad-
apter(3) from the piston(4).
NOTICE!
The adapter is secured with locking varnish
(Loctite no. 243). You will need somewhat more
strength than usual to loosen it.
Hold against it with a spanner wrench.

Installation
Fig.363: Installing the articulated joint
► Screw the articulated joint into the short-stroke
cylinder with a torque of 22Nm. Make sure that
the joint (1) is horizontal so that it fits into the re-
cess in the moveable blade. Secure the screw
with Loctite243.
CAUTION!
The articulated joint must be horizontal. If not,
the blades could be distorted, which will then
cause the joint to break.
.
► Screw the articulated joint to the moveable blades. Tighten the screws to a torque of 6 Ncm.
► Follow the removal instructions in reverse order for further installation. Also observe the fol-
lowing instructions:
CAUTION
Installation instructions
► Grease the articulated joints slightly with "Klüber BEM 34-132 lubricant grease".
► Secure the screws with Loctite 243.
► Insert the new screw caps. Remove the protruding plastic residues with a knife.
► Connect the compressed air hoses to the cylinder in the correct allocation.
► Check the gap between the leading edge of the tape deflector and the "empty-tape
baffle, inside".
NOTICE
If the tapes are not cut correctly.
If the tapes are not cut correctly, even though the switching points have been set properly
and the short-stroke cylinder has been exchanged - complete with the one-way restrictor -
the cause of the problem may be:
► Incorrect compressed air level
► Leaking compressed air connection or Y-socket union

Fig.364: Removing the short-stroke cylinder
► Use a permanent marker to mark the exact in-
stallation position of the proximity switch (1) on
the short-stroke cylinder.
► Remove the screws fastening the two inductive
proximity switches (1) to the short-stroke cylinder.
► Remove the compressed air connections (2) on
the short-stroke cylinder. You may want to mark
their positions to make clear assignment easier
later on.
► Remove the two screws (3) fastening the short-
stroke cylinder.
► Remove the short-stroke cylinder (4) from the
cutter.

Fig.365: Fitting the articulated joint and proximity switches
► Apply a small amount of Loctite243 to the thread
(2) of the new articulated joint.
► Screw the articulated joint (1) into the short-
stroke cylinder.
► Turn the articulated joint in its installation posi-
tion(3).
Once the cylinder is installed, the slot in the
moveable blade prevents the articulated joint
from turning.
► Copy the exact installation position of the proxim-
ity switch(4) onto the new short-stroke cylinder
(e.g. with a feeler gauge, fine-tipped marker pen).
