20 To adjust the initial position of the moving knife (Fig.16)
Adjust the moving knife (I1/20,I2/36) into the initial position. A clearance of approx. 1 mm must
be provided between the top end of the moving knife and of the counter knife.

21 To adjust the tension thread controller (table A2 – Parts Book)
The tension controller consisting of parts (A2/6,31,7,8,9) influences the lenghts of trimmed ends
in the material and also the lenght of the top thread in the needle after the trimming in
dependence on the used threads and material. It must be adjusted in the way so that the thread
lever could tighten the upper thread to the moving knife, also at the state of detached main
tension controller and also with the fastened lower thread.
22 Conclusion:
When all the trimmer functions have been adjusted as described above, check them as follows:
Insert a bit of material under the top roller, sew a few stitches by hand and check whether the
treads pass through their ducts unobstructed. Then tilt the machine, insert the revolving pin into
the cam controlling the trimmer device drive, rotate the hand wheel and observe the trimmer
device function. When adjusted correctly, the trimmer device cuts the two threads, and the
lower thread end is clamped between the clamping spring and the moving knife. Then check up
the machine in the process and observe esp. tension thread controller etc.
Note: The moving knife must always fasten the lower thread end to the back groove when
moving forward, and the upper thread end to the front groove ( at the trimming hole) when
moving backward.
