Threading the lower looper thread (yellow)
Attention!
Before threading, ALWAYS place the power switch 8 at "O" (Off) and
remove the plug from the mains power socket. This prevents an unintended
starting of the machine. If you do not, you run a risk of serious injury!
Figure 19 shows the thread path of the lower looper thread. The individual
threading positions are numbered and described in detail in the following.
1. Guide the yarn from back to front through the thread tree 1 (1).
2. Thread the yarn into the thread guide in that you pull the thread down
until it slips under the thread guide (2) (Fig. 20).
3. Firmly hold the yarn with your fingers, guide it between and through
the discs of the thread tension selector u and then pull it down (3)
(Fig. 21).
Note:
The yarn must lie correctly between the two discs of the thread tension
selector u.
4. Turn the handwheel 6 to yourself until the lower looper p is at the
far right.
