upper cutting edge.

–
With the lowered edge trimmer loosen the fixing bolt (1) on the
cutting knife holder (2).
–
The cutting knife (3) will be pressed, by means of a spring, onto the
cutting edge of the throat plate insert (4).
–
Tighten the bolt (1) strongly and check the pressure and correct
cutting function.
If the setting range of cutting knife holder is not sufficient applied as
above described, make a modification of the trimming mechanism
position as follows:
–
Put the Allen key (5) sized 5mm through the cover rear hole (6) in
the respective screw and loosen it.
–
Move the inserted setting pin (7) in the hole in the part (8) in the
direction up and down, by which we roughly adjust, by means of
the movement of the whole drive mechanism, the lateral position of
the knife holder (2).
–
In the position set with the key (5) tighten the rear fixing bolt and
finely adjust the lateral position of the cutting knife in the way
described in the previous paragraph.
Attention!
The cutting knife must not strike the throat plate insert from above with
its tip, when it is lowered into the switch-on position, or it must not be
bent as a result of a strong pressure on the fixed knife.
