C.5.11 Adjusting the kettup knife and stop
The standard version of the machine is equipped
with a stop that is secured to the contour guide.
Optionally, the machine can be equipped with a
pneumatic stop.
Fixed stop:
Fig. 8: The contour guide stop 3 must be offset
slightly at a distance A of 0.2-0.3 mm in front of the
chain cutter knife. The knife must cut thread and fa-
bric residues, but not the sewing piece hem.
To adjust this offset, the entire contour guide is shif-
ted on the cover plate which is installed loosely into
the working table recess and secured by magnets.
1. Lift cover plate with contour guide.
2. Remove the two contour guide retaining screws
5 at the front of the cover plate; loosen the con-
tour guide retaining nut 4 at the rear of the cover
plate only enough to shift the contour guide.
3. Reinstall cover plate and shift contour guide so
that the distance A (between chain cutter knife 2
and stop 3) is approx 0.2-0.3 mm. Check dis-
tance using a feeler gauge.
4. Tighten the two retaining screws 5 at the front of
the cover plate.
5. Remove cover plate and tighten the contour guide
retaining nut 4.
6. Align pressure foot 1 to stop 3. Loosen pres-
sure foot locating screw, push pressure foot close
to stop, then tighten locating screw. The distance
B between pressure foot and chain cutter knife
should be approx 0.5 mm.
Pneumatic stop:
With this option, a pocket pouch can be inserted bet-
ween trousers panel and lining and serged.

pouch is sewn manually, the remaining section of the
seam is sewn fully automatically.

sewing function STATION CLOSE. At the end of this section, the trans-
port unit is lowered, the pneumatic stop moves to the pressure foot, and
the contour guide controls the seam.
