Installing the New Blades and Matched Spacers
X 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!
X Holding the articulated joint with a size 10
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 This may require more strength than usual as
the screws have been secured with Loctite no.
243.
X 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!
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.
NOTE:
X Make sure all parts are clean before installing them!
X The new blades are covered with a fine lubrication film.
X Do not use fat dissolving agents on the blades (risk of rust film forming) or apply any
additional lubrication (risk of contamination by particles sticking to the blades).
X This would only impair the movement of the moveable blade.

CAUTION:
X Make sure the cutter is in the correct
rotary position (see the slant of the
blade).
X Tighten the screws to the correct
torque.
X Insert the movable blade into the cutter, in the
correct rotational position, while pushing it into
its original mounting position.

X Apply Loctite no. 243 to the two M4 screws (7),
to fasten the joint in the moveable blade.
X Reinstall 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 (5, 6), so
that the articulated joint can slide
smoothly in the slot (= prevents turning)
of the movable blade .
X Use an SW 10 open-ended wrench to push
against the relevant articulated joint and
tighten both screws to the correct torque.
X Place the two new spacers to the left and right
of the moveable blade. The spacer side
marked with a number must face towards the
blade.
The spacers and blades are matched !
4-32: Mounting new blades, mounting position of the blades, slide surfaces
to be greased
X Grease the contact / slide surfaces for the
movable blade exactly in the area shown (3).
Do not lubricate the blades themselves.
X Place an adjustment plate (0.5 to 1.0 mm
thick) on the left and right, between the spacer
and the face of the movable blade.
X Place the holddowns previously removed back
on the new spacers.
The version 03 holddowns match the version
04 cutters (= with tape deflector)!

X Using the feeler gauge, check the gap between tape deflector and movable blade, over the entire
length and width of the blade:
The 0.05 mm feeler gauge should fit through the gap.
The 0.25 mm feeler gauge should not fit through the gap.
If the gap is not correct, check:
X Whether the wrong holddowns has been installed (with function status < 03).
The holddowns are those designed for cutters with function status -04 (= with tape deflector).
X Whether the blades, tape deflector etc. were cleaned before installation
If the gap is correct:
X Carefully fold the cover plate (with cover plate holders installed) back over the tape deflector.
X Reinstall the previously removed deflector
holder (= with tape deflector) and initially
tighten the 4 hexagon socket head screws (9)
hand-tight.
X Push the spacers (with inserted adjustment
plate) towards the movable blade - up to the
stop but not until they exert pressure against it,
otherwise it would no longer be possible to
remove the adjustment plates.
The maximum permissible gap is 1.0 mm.
X In this position, tighten all 4 screws on the tape
deflector holders crosswise.
Tighten the screws to the correct torque.
X Remove the two shim rings.
X Insert the new stationary blade in the correct
position ((see diagram) and screw tight (2
screws).
Tighten the screws to the correct torque.
