► Remove the right-hand holding-down device (1)
and the left holding-down device (2), plus the
spacers below.
► Use an SW10 open-ended wrench to push
against the joint (3), while loosening the hexagon
socket-head screw of the joint (4) in the move-
able blade. This may require more strength than
usual as the screws have been secured with Loc-

Installation – requirements
CAUTION
Risk of injury!
There is a high risk of injury from the blades and the tape deflector.
●
Wear appropriately thick protective gloves!
●
Make sure all parts are clean before installing them.
●
Do not use fat dissolving agents on the blades (risk of rust film forming).
●
The new blades are covered with a fine lubrication film.
The blades may only be greased with the lubricants described in the maintenance manual.
Any other lubricant would impair the movement of the moveable blade.
●
If the new blades are not clean, carefully clean them (wear protective gloves) with a clean
brush or a well folded, clean and dry cloth.

► Make sure the cutter is in the correct rotary position (see the slant of the blade).
► Check the positioning of the individual blades to one another.
► Before installation, lubricate the sliding side surfaces of the moveable blade with Klüber BEM
34-132 and make sure that the recesses are filled. These will be refilled later on during main-
tenance with the lubrication nipples.

provided in the moveable blade.
NOTICE!
Make sure that the joint (3) can slide into the slot
(=anti-twist function) in the moveable blade
without obstruction.

► Fit the two caps over the fastening screws on the movable blade.
► Place the two new spacers (4) to the left and right of the moveable blade. The spacer side
marked with a number must face away from the blade.
CAUTION
The spacers and blades are matched!
► Do not use any spacers from other sets of blades.
► Lubricate the contact/slide surfaces for the moveable blade, as described in the section "Pre-
parations".
CAUTION
Only apply grease to the exact points required!
The overlapping cutting surfaces may only be greased with Interflon Fin grease
[03020782-xx]. Also observe the preventive maintenance manual for your machine.

► Place a shim (0.5 - 1.0 mm thickness) on the left
and right, between the spacer and the front of the
movable blade (1).
► Place the previously removed holding-down
device (2) onto the new spacers.
NOTICE!
Holding-down device
The holding-down devices with version 03 are
those designed for cutters with version 04 (=
with tape deflector)
.
► Insert the dismantled wiper unit (3) and the holding-down devices and tighten loosely with the
four hexagon socket-head screws (4).
► Push the spacers (with inserted feeler gauges) as far as possible in the direction of the move-
able blade. The maximum permissible gap is 1.0 mm.
► Now tighten the four screws (4) crosswise at the holding-down device.
► Remove the two feeler gauges.
► Insert the new stationary blade (5) in the correct position and screw tight.
