Specifications

If you rotate less than 2 spokes you will begin to lose the force needed to make a
tight stitch. You may have enough stroke but not enough force to cinch up the
stitch tightly. You may also begin to have failure of thread break detection. You
must have enough rotation to cause the check spring to make a good contact with
the thread break contact post. A poor contact will often not provide the signal to
stop embroidering when there is a thread break.
Replacing A Thread Break Contact Post
1. As described previously in this manual, remove the thread tensioner associated
with the thread break contact post to be replaced.
2. Remove the thread break contact post (see Figure 3-15) by rotating it
counter-clockwise out of its location in the thread tensioner bracket.
3. Install the new thread break contact post by rotating it clockwise into the
tensioner bracket.
Secure the post "finger-tight" only.
CAUTION! Use care not to cross thread the post when installing it.
4. Reinstall the thread tensioner and check spring as described in a previous
procedure in this section, then perform check spring adjustment.
