1. Cleaning
The Thread Break Contact Posts
Clean the thread break contact posts using a cotton swab dipped in alcohol.
If deeper cleaning is necessary, refer to Figure 1-14 and the following
procedure:
EMC 6, 6M, 6ML, 6MLT, EMC6/4M, EMC6/4MT:
In order to clean the base of the thread break contact posts, the PCB must
be removed.
Figure 1-14
EMC 10, EMC 10T EMC 10/4, EMC 10/4T:
Each thread tensioner assembly 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.
- Using a 2.5 mm allen wrench, loosen the set screw associated with the
thread tensioner to be removed.
- Pull the thread tensioner assembly out of the tensioner bracket.
- The thread tensioner post may now be removed by unscrewing.
- To reinstall the thread tensioner, reverse the preceding steps. Note:
Be sure to fully seat the tensioner into the hole in the bracket.
- After inserting the thread tensioner into the tensioner bracket, perform
the thread tensioner check spring adjustment, located in the Technical
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.
