of the fork (3) must intersect the axis of the shaft (4).

Caution!  Danger  of  injury!

Switch  off  the  main  switch!  Before  starting  the

setting  operation,  wait  until  the  motor  stops!

- Shift the shaft (5), until the holder (1) strikes the bracket (2).

- Loosen the screw (6).

- Shift the fork (3) in such a way that its axis intersects the axis

- Tighten the screw (6).

4.5 Setting the moving knife

The  moving  trimming  knife  (1)  is  to  be  placed  in  its  starting

position  at  rest  with  its  end  at  the  distance  of  the  measure

„A“= 0.1 to 0.5 mm from the edge of the fixed trimming knife

(2).

The height setting is to be such that its top surface is 1.8 mm

below  the  top  surface  of  the  throat  plate.

Caution!  Danger  of  injury!

Switch  off  the  main  switch!  Before  starting  the

setting  operation,  wait  until  the  motor  stops!

- Loosen the screws (4 and 5).

- Turn the moving trimming knife (1) in the sense of the arrow

and set it in height. Tighten the screw (5).

- Turn the moving trimming knife (1) into its starting position

in  such  a  way  that  the  measure„A“  =  0.1  to  0.5  mm  is

attained.  Tighten  the  screw  (4).

4.6 Setting the fixed knife

The  fixed  trimming  knife  (1)  is  to  be  tensed  up  by  the  screw

(2) in such a way that it bears on the moving trimming knife in
