4.3.2.7 Replacing the Stationary Blade and Movable Blade incl. Spacers
Replacing the Stationary Blade and Movable Blade incl. Spacers
Removing the Old Blades incl. Spacers
WARNING! Wear appropriately thick protective
gloves!
There is a high risk of injury from the blades and the tape
deflector.
Never reach into the cutter from below or into the empty-
tape duct from above.
Make sure that no-one can injure themselves on the cut-
ter, after it has been dismantled and placed next to the
machine!
NOTICE! The stationary blade and the movable
blade, including the spacers, must always be exchanged
as a set, if both cutting edges are blunt.
The blades which are removed can be reground at the
factory (Siemens facility).
► Remove the cutter from the machine. (See "4.3.2.5
Exchanging the Pneumatic Cutter" [ ➙ 83].)
► Dismantle the deflector plate (12): 4 hexagon socket-
head screws M4 x 8 (13).
► Loosen the screws fastening the stationary blade on
the left and right (2).
► Mark the mounting position of the stationary blade
(on the blade) with a water-insoluble marker (= right
end = right).
► Before any further disassembly, fasten the disman-
tled 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
► Remove the stationary blade. (See "4.3.2.6 Turning
the Stationary and Moveable Blade by 180 °"
[ ➙ 87].)

Installing the New Blades and Matched Spacers
► If the new blades are not clean, carefully rub them (wear protective gloves) with a well folded, clean
and dry cloth. Do not use fat dissolving agents!
► Loosen the fixtures on the left and right tape deflector
holders above the movable blade (2 screws each on
the left and right, outer edge (7, 9). Do not loosen the
two Phillips screws (10).
► Remove the tape deflector holder (incl. cover plate
and tape deflector) and set this unit down carefully
(with the tape deflector up).
NOTICE! Only 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 matched.
► Remove the two holddowns and the spacers under-
neath them (11).
► Holding the articulated joint with a size 10 open-end
wrench (3), loosen the screws fastening the articulat-
ed joint in the movable blade (1 hexagon socket-head
screw each on the right and left (4)).
► This may require more strength than usual as the
screws have been secured with Loctite no. 243.
► Using protective gloves, take hold of the stationary
blade by its ends and lift it up and out of the cutter.
WARNING
Risk of injury!
► Wear appropriately thick protective gloves!
► There is a high risk of injury from the blades and the tape deflector.
NOTICE
► Make sure all parts are clean before installing them!
► The new blades are covered with a fine lubrication film.

movable blade
4. Holddowns
5. Spacer
6. Contact surface
CAUTION! Make sure the cutter is in the correct
rotary position (see the slant of the blade).
Tighten the screws to the correct torque.
► Insert the movable blade into the cutter, in the correct
rotational position, while pushing it into its original
mounting position.
► Apply Loctite no. 243 to the two M4 screws (7), to fas-
ten the joint in the moveable blade.
► Reinstall these screws, on the left and right, in the
movable blade.
NOTICE! Make certain that the midline / open-
end wrench surface of the articulated joint is at right an-
gles 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 .
► Use an SW 10 open-ended wrench to push against
the relevant articulated joint and tighten both screws
to the correct torque.
► Place the two new spacers to the left and right of the
moveable blade. The spacer side marked with a num-
ber must face towards the blade.
⇨ The spacers and blades are matched !
