19. Converting to two-thread operation
You can also use your machine solely as a two-thread machine. To do so,
use the two-thread converter (59).
Please refer to the table in section "11. Overview of machine settings" on
page 237 for the various applications of the two-thread converter.
1. Switch off the machine and pull out the mains plug.
2. Open the looper cover (13).
3. Place the upper looper (42) in the highest position with the
handwheel.
4. Depending on the desired seam, remove the needle that is no longer
required, and the threads for this needle and for the upper looper
(see also "24. Replacing needles" on page 251).
5. Insert the two-thread converter in the recess on the upper looper.
6. Then carefully turn the two-thread converter to the left and ensure
that the point pin on the two-thread converter locks into place in the
looper eye.
If necessary, use the tweezers to help.
7. Follow the specified steps in the reverse order to remove the two-
thread converter.
