• Open the blade holders by turning the threaded spindle
(28) counter-clockwise.
• With the larger diameter forward slide brass sleeve (30)
onto the pin of the calibration kit (Fig. 21 + Fig. 22).
• By turning threaded spindle (28) clockwise close the blade
holders until the blade holders (11) are in contact with the
cross pin (26) of the calibration kit (Fig. 22).
• Turn the eccentrics counter-clockwise until the two central-
izers (13) slightly contact the smaller diameter of the brass
sleeve (30) (Fig. 17, page 34 and Fig. 22).
• Turn the threaded spindle (28) counter-clockwise until both blade holders (11) are in its fully
open position.
• Tighten both set screws (23) of the eccentrics carefully (Fig. 17, page 34).
• Inspection: When turning the treaded spindle both centralizers must simultaneously contact the
small diameter of the brass sleeve (30).
• In this position slide the brass sleeve (30) forward a little bit until its larger diameter contacts the
centering guide (Fig. 23, page 37).
