11.6.4.2 Installing the Short-Stroke Cylinder / the Articulated Joint
WARNING
You might cut yourself on the blades and the tape deflector. 11
CAUTION
Tighten the screws to the correct torque -> see Table, Fig. 11.4.2. 11

Key to Fig. 11.6.4 (right):
1. Short-stroke cylinder (1 or 2)
2. Articulated joint (complete)
3. Wrench surface for disassembling the articulated joint
4. Secure articulated joint thread with Loctite no. 243
5. Open-end wrench surface of articulated joint
6. Slide surface of the movable blade
7. Screw fastening the articulated joint to the movable blade:
one M4 x 24 DIN 912 socket hex head cap screw each, strength 12.9,
secured with Loctite no. 243

Fig. 11.6.4 Removing Articulated Joint, Installing It on New Master Cylinder and Bonding It in Place
à If the articulated joint is damaged, use a (complete) new one (Item no.: see Section 11.2) or
clean the residues of Loctite from the thread of the existing articulated joint pin.
à Apply a small amount of Loctite no. 243 (Item no.: see Section 11.3) to the thread.
à Take note of the following WARNING. If the enamel on the one-way restrictor is damaged use
a new "short-stroke cylinder assembly HS-50".
DANGER
One-way restrictors are not to be set on the machine. This is only permitted at the factory.
For this reason the replacement short-stroke cylinder must always be installed, together with the
new, already adjusted restrictors attached to it. 11
à Screw the threaded pin into the short-stroke cylinder. If necessary use a new "short-stroke cyl-
inder assembly for HS-50" (Item no.: see Section 11.2).
à Turn the articulated joint into the mounting position (see Fig. 11.6.4: diagram on left) and
tighten the articulated joint against the wrench surface.
Once the cylinder is installed, the slot in the movable blade prevents the articulated joint from
turning.
à Copy the exact mounting position of the proximity switch from the old short-stroke cylinder to
the new one (feeler gauge, fine-tip marker).
à Having thus prepared the cylinder, install it, complete with one-way restrictors and incl. the ar-
ticulated joint, on the cutter in the correct rotational position.
