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.

► Correctly insert the moveable blade (1) into the
cutter and shift it along to its original installation
position.
► Apply Loctite243 to the two M4 screws to fasten
the joint in the moveable blade.
► Insert the screws (2) into the left and right holes,
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.
.
► Use an SW10 open-ended wrench to push against the relevant joint (3) and then tighten both
screws(2) to a torque of 6Nm.

11.9 Replacing the Cutter Blades
268 Service Manual SIPLACE TX Series 06/2017
► 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.

Fig.376: Cutter (using example of X-Series)
► Use a feeler gauge to check the gap between the
tape deflector (1) and the moveable blade (2),
along the entire length and width of the blade.
ð The 0.05 mm feeler gauge should fit through
the gap.
ð The 0.25 mm feeler gauge should not fit
through the gap.
If the gap is not correct, check:
●
Whether the wrong holding-down device has
been installed (with function level < 03).
●
The holding-down devices are those designed for
cutters with function status -04 (= with tape de-
flector).
●
Whether the blades, tape deflector etc. were
cleaned before installation.
If the gap is correct:
► Fit the baffle plate and cover plate. Make sure that the edges are parallel.
CAUTION
Check how the cables are run!
Make sure that the cables and hoses are not pinched or subjected to excess strain.
► Remove the clamps from the cutter/remove the cutter from the assembly plate.
► Further installation is performed by following the above instructions in the reverse order.
