4.3.2.6 Turning the Stationary and Moveable Blade by 180 °
Removing the Blades
NOTE:
The movable blade has a cutting edge on both sides.
If one cutting edge becomes worn, the blade can still be used by turning it 180° on its vertical
axis and reinstalling it.
At the same time, the stationary blade must also be turned 180° on its vertical axis and installed.
If both edges are already blunt, replace the blades.
WARNING: Risk of injury!
There is a high risk of injury from the
blades and the tape deflector.
X Wear appropriately thick protective
gloves!
X Never reach into the cutter from
below or into the empty-tape duct
from above.
X Make sure that no-one can injure
themselves on the cutter, after it has
been dismantled and placed next to
the machine!
X Remove the cutter.(See section (4.3.2.5 Ex-
changing the Pneumatic Cutter
J
87 ) .)
X Dismantle the deflector plate (12): 4 hexagon
socket-head screws M4 x 8 (13).

4-30: Removing/fitting the stationary and movable blade
Legend
X Loosen the screws fastening the stationary blade on the left and right (2).
X Mark the mounting position of the stationary blade (on the blade) with a water-insoluble marker (=
right end = right).
X Before any further disassembly, fasten the dismantled cutter to the retaining bracket (LH and RH)
with 2 parallel clamps, on a flat sturdy work bench, or screw it tight to the mounting plate with four
M6 hexagon socket head screws
X Remove the screw caps.
X Take hold of the stationary blade (1) by its ends and lift it up and out of the machine.
X Holding the articulated joint with a size 11 open-end wrench (3), loosen the screws fastening the
articulated joint in the movable blade (1 hexagon socket-head screw each on the right and left(4)).
X Push the movable blade in parallel (in the direction of the conveyor), until it is in the mounting position
of the stationary blade (for the direction of movement see (6)). Using a tool such as a screwdriver,
move the blade by alternately prying on the left and right next to the compressed air cylinder.
X Mark the mounting position of the movable blade (on the blade) with a water-insoluble marker (right
end = right).
X Lift the movable blade out of the cutter in this position.

Installing the Blades
X Afterwards, rotate the stationary blade 180° on its vertical axis to the original installation position,
insert it into the cutter in this position and screw it tight. The right-hand end of the blade must now
be on the left!
X Fit the stationary blade.
X Assemble the cutter in the reverse order to disassembly.(See section (4.3.2.7 Replacing the Statio-
nary Blade and Movable Blade incl. Spacers
J
95 ) .)
WARNING: Risk of injury!
X Wear appropriately thick protective gloves!
X There is a high risk of injury from the blades and the tape deflector.
X Never reach into the cutter from below or into the empty-tape duct from above.
CAUTION:
Tighten the screws to the correct torque.
Make sure all parts are clean before installing them!
Do not use grease dissolving agents for cleaning!
X Wear appropriately thick protective gloves!
X Make sure that the blades (1, 5) are clean. If
they are not, wipe all of their surfaces very
carefully with a clean cloth which has been
folded several times.
X Turn the movable blade 180 ° on its vertical
axis to the previously marked installation
position:
X Insert the movable blade into the cutter, in this
angle of rotation and push it in parallel, back
into the original mounting position.
X Apply Loctite no. 243 to the two M4 screws (4),
to fasten the joint in the moveable blade.
X Reinsert these screws in the left and right of
the movable blade.
X Align the articulated joint (3) so that the slanted
side of the blade engages with the slot in the
blade.
NOTE:
Make certain that the midline / open-
end wrench surface of the articulated
joint (2) is at right angles to the slide
surface of the movable blade (5, 6), so
that the articulated joint can slide
smoothly in the slot (= prevents turning)
of the movable blade (8) .
X Use the size 11 open-end wrench to hold the
appropriate articulated joint (2) and tighten the
two screws (7) .
