Replacing the blades

Unscrew clamping screw (630).
Rotate or replace the blade.
Adjust cutting gap as described above.
Please note: The height of blade (480) in plunger
(430) is adjusted best when –with the
greatest possible distance between
plunger (430) and shoe (470)– the
back points of the two blades (480)
are at the same level and do not
overlap.
Adjustment with shoe (470) removed.
Fine adjustment by turning connecting rod (500)
by a half.
Final test according to point 2.
