C.5.11 Adjusting the kettip knife and stop
Fig. 10: 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 fabric residues, but not the se-
wing piece hem.
To adjust this offset, the entire contour guide is
shifted on the cover plate which is installed loo-
sely into the working table recess and secured
by magnets.
1. Lift cover plate with contour guide.
2. Remove the two retaining screws 5 at the
front of the cover plate; loosen the contour
guide retaining nut 4 at the rear of the co-
ver 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 distance 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
pressure 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.
