3.9.7 Replacing the Cutter Blades Cutter
Service Manual SIPLACE SX4/DX4 165
Installation – requirements
▪ Wear appropriately thick protective gloves!
▪ Make sure all parts are clean before installing them.
▪ The new blades are covered with a fine lubrication film.
Do not use fat dissolving agents on the blades (risk of rust film forming).
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.
Do not use fat dissolving agents!
Installation – preparations
► 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 maintenance with
the lubrication adapter.
Cutter (using example of X series)
► Remove the right-hand holding-down device (1) and
the left holding-down device (2), plus the spacers be-
low.
► 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 moveable blade.
This may require more strength than usual as the
screws have been secured with Loctite no. 243.
► Grasp both ends of the moveable blade (5) with the
protective gloves and pull it upwards and out.
