NOTE:
Only the product version 03 holddowns are to be used for version 04 cutters (= with tape deflector).
The spacers removed are always replaced by the new spacers included in the blade set.
Blades and spacers are attuned (= match). 11
à Remove the two holdowns and the spacers underneath them (see Fig. 11.4.2 -> 11).
à Holding the articulated joint with a size 10 open-end wrench (see Fig. 11.6.1 -> 3), loosen the
screws fastening the articulated joint in the movable blade (1 socket hex head cap screw each
at right and left, see Fig. 11.6.1 -> 4).
The screws are secured with Loctite no. 243, so considerable strength may be necessary.
à Use protective gloves and take hold of the stationary blade by its ends and lift it out of the cut-
ter.
11.6.3.2 Installing the New Blades and Matched Spacers
WARNING
Wear thick protective gloves.
You might cut yourself on the blades and the tape deflector.
Never reach into the pneumatic cutter from below or into the empty-tape duct from above. 11
NOTE
All parts must be clean before installing.
When the blades are delivered they have a very fine film of grease on them.
They are not to be treated with fat dissolving agents (risk that rust film may develop), nor are they
to be coated with more grease (risk that they may become dirty due to adhesion of solid
particles).
This would cause a detrimental effect on the movement of the movable blade. 11
à If the new blades are not clean, wipe them off very cautiously (protective gloves) on all sides
with a clean, carefully folded cloth.
-> Do not use any grease dissolving agents.

Fig. 11.6.2 Mounting New Blades, Mounting Position of the Blades, Slide Surfaces to be Greased
Key:
1. Stationary blade
2. Movable blade
3. Slide surfaces to be greased before installing the movable blade.
4. Holddown
5. Spacer
6. Contact surface
CAUTION
When installing new blades, place the blade so that the blade slope is in the correct rotational po-
sition (see Fig. 11.6.2).
Tighten the screws to the correct torque -> see Table, Fig. 11.4.2. 11
à Insert the movable blade into the cutter in the correct rotational position while pushing it into its
original mounting position.

à Apply Loctite no. 243 (Item no.: see Section 11.3) on the two M4 screws used to fasten the ar-
ticulated joint in the movable blade (details: see Fig. 11.6.4 -> 7).
à Re-install these screws on the left and right in the movable blade.
NOTE:
Make certain that the midline / open-end wrench surface of the articulated joint is at right angles
to the slide surface of the movable blade (see Fig. 11.6.4 -> 5 and 6) and that the articulated joint
can slide in the slot (= prevents turning) in the movable blade. 11
à Using the size 10 open-end wrench to hold the appropriate articulated joint, tighten both
screws with the mentioned torque (see Table, Fig. 11.4.1)
à Place the 2 new spacers (Item no.: see Section 11.2) to the left and right of the movable blade
(see Fig. 11.4.2 ->11).
– Spacers and blades are attuned (= match).
à Grease the contact / slide surfaces for the movable blade exactly in the area shown in Fig.
11.6.2 -> 10 (Item no. of the grease: see Section 11.3).
-> Greasing the blades is not allowed.
à Place an adjustment plate (0.5 to 1.0 mm thick) on the left and right between spacer and the
face of the movable blade.
à Place the holddowns previously removed back on the new spacers.
-> The version 03 holddowns match the version 04 cutters (= with tape deflector).
à Re-install the previously removed deflector holder (= with tape deflector) and tighten the 4
socket hex head cap screws (see Fig. 11.4.2 -> 9), just hand-tight at first.
à Push the spacers (with inserted adjustment plate) toward the movable blade to the stop but not
until they exert pressure against it, otherwise it would no longer be possible to remove the ad-
justment plates.
– The maximum permissible gap is 1.0 mm.
à In this position, tighten the 4 screws on the tape deflector holders crosswise (torque: see Table
in Fig. 11.4.2).
à Remove the 2 adjustment plates.
à Insert the new stationary blade in the correct position (see Fig. 11.6.2) and tighten the 2 screws
(see Fig. 11.6.1 -> 4).
-> Tighten the screws to the correct torque -> see Table, Fig. 11.4.2.
à Using the feeler gauge, check the gap between tape deflector and movable blade (see detail
in Fig. 11.4.3) over the entire length and width of the blade:
à It must be possible to pull the 0.05 mm feeler gauge through it.
à It must be impossible to pull the 0.25 mm feeler gauge through.
