, unscrew it (hold shaft

with open-
end wrench 5 mm).
CAUTION:

The nose of knife (3) should sit in the shaft's groove to guarantee the right position for
the thread trimming.
- Turn the main shaft manually and check the trimming position. (Fig. 17)
3.9.4 Cutting position (Fig. 17)
The machine should be positioned in such a way as the pedal is stepped back that the
distance between looper and blade in cutting position is approx. 1 mm.
For Strobel and EFKA controls, this corresponds to parameter 171, position P2E.
Refer also to the sewing drive operating instructions.
