Installation – preparations
► Clean all parts and the cutter before installation. Observe the following points:
▪ The new blades are covered with a fine lubrication film. 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). This would only impair the movement of the moveable blade.
▪ 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!
▪ Before installation, lubricate the sliding surface of the moveable blade.
▪ Clean all metal parts on the left and right of the cutter and the return rods to remove grease and con-
taminants.
▪ If present, any side buffers on the blades must be checked and replaced if necessary.
► Unplug the electrical connections (2) from the
valves (1).
► Unplug the pneumatic hoses (3) from the valves.
Mark their positions, to make clear assignment easier
later on.
► Remove the two fastening screws on the terminal
strip.
The terminal strip is now only connected to the cables.
► Swing the top cover (3) forwards.
► Undo the two screws (2) fastening the fixed blade (1)
and then remove the blade.
► Take the moveable blade (2) out of the cutter.
► Remove the covers (3) [03087746-xx] on the fasten-
ings screws.
► Undo the screws (3) fastening the return rods (1) and
then remove the return rods.
▪ Grease the contact and sliding surfaces (1) for the
moveable blade with Klüberplex BEM 34-132.
CAUTION!
Do not grease any other surfaces on the blade.
