2 Assembling the neat seam beginning (NSB)
When the needle exits the sewing material after the first stitch, the thread-
pulling knife pulls the initial thread into the clamp. This ensures secure
sewing.
Following the 2nd stitch, the remaining thread is cut off and removed by
the suction device.
2.1 Presettings outside of the machine (optional)
The kit has been preset at the factory and does usually NOT have to be
adjusted.
Do not check or adjust the presettings outside of the machine UNLESS
the NSB is without function.
Fig. 1: Presettings outside of the machine (1)
To complete the presettings outside of the machine:
1. Remove the clamping spring (1).
2. Loosen the nut (2).
3. Extend cylinder (4).
4. Turn the piston rod (3).
Measurement Amust be 8.8 mm with the cylinder fully extended (4).

2.2 Checking and adjusting the cutting pressure
Fig. 4: Checking and adjusting the cutting pressure
Proper setting
Screw (1) is adjusted such that the thread-pulling knife (2) moves
smoothly and the counter blade (3) cuts the loose thread cleanly.
To check and adjust the cutting pressure:
1. Screw in screw (1) in such a way that the screw head abuts on
the counter blade (3).
2. Turn the screw (1).
• Increase the cutting pressure: Turn screw (1) clockwise
• Reduce the cutting pressure: Turn screw (1) counterclockwise
3. Carry out a cutting test.
4. Readjust the cutting pressure if necessary.
NOTICE
Property damage may occur!
Risk of knife breakage if pressure is adjusted too high.
Do not adjust the cutting pressure too high.

2.3 Checking and adjusting the clamping spring pressure
The clamping spring clamps the needle thread after the 1st short stitch
and prior to cutting.
Fig. 5: Checking and adjusting the clamping spring pressure
To adjust the clamping spring pressure:
1. Adjust screw (1) such that the needle thread is securely clamped by
the clamping spring (2).
