Tensioning Cable

Cable should have enough tension so it stays seated into the pulley but not so tight that it raises the head plate off the weight plate below it.
  1. If the head plate has lifted, loosen the jam nuts at the terminations and loosen the threaded plugs a half turn until the head plate comes to rest on the weight plate below. Check that the threaded plugs are engaged at least 1/2” (12.7mm) at each termination.
