2. Carefully grasp the thread guide tubes individually and remove them from the

Individual Thread Tensioner Replacement
Each thread tensioner is secured by a set screw against the thread tensioner shaft
inside the thread tensioner bracket. The set screw is accessible through a slot at the
top of the tensioner bracket.
1. Using a 2.5 mm hex wrench, loosen the set screw associated with the thread
tensioner to be removed (see Figure 3-12).
2. Pull the thread tensioner out of the tensioner bracket.
3. To reinstall the thread tensioner, refer to the next procedure for changing a
check spring.
4. After inserting the thread tensioner into the tensioner bracket, the tensioner disk
may wobble while it is rotating. This is caused by the plastic disk not being fully
seated on the post. Grasp the plastic disk between your thumb and forefinger;
and while twisting back and forth, push to seat the disk fully on the post.
5. Perform the thread tensioner check spring adjustment that follows the check
spring replacement procedure. The adjustment procedure, not only adjusts the
check spring tension, but secures the thread tensioner in the tensioner bracket
by tightening the set screw previously loosened in this procedure.
