Replacing An Individual Thread Tensioner
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 3-20).
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, perform the
thread tensioner check spring adjustment from Section 2 of this manual. This
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.
Changing A Check Spring
1. As described previously in this manual, remove the thread tensioner associated
with the check spring that is being changed.
2. Remove the old check spring and discard it.
