RE-ADJUSTING THE THREAD TENSION
All JessEm Lifts feature our patented thread
tensioning design. Thread tension is set at the
factory and depending on the amount of use you
may have to reset this adjustment periodically,
depending on the amount of tension you desire.
If the bit height ever begins to change (or drop)
during use, the thread tensioning likely needs to be
reset.
