4.8.3 Replacing the knife (Fig. 8 and Fig. 9)
A t t e n t i o n !
Switch off machine electrically!
To replace cylinder head screw 171.0421, unscrew it (hold shaft 130.0394 with
open-end wrench 5 mm).
Caution: Do not hold onto the rotary knob 246.0188 since the gearwheels can
be damaged!
The nose of knife 184.0096 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. 9)
4.8.4
The machine should be positioned in such a way as the pedal is stepped back
that the distance between gripper 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.
