Proper Adjustment With the auger clutch lever in
the disengaged position the top surface of the new
belt should be even with the outside diameter of the
pulley. To adjust, disconnect ferrule from the brake
bracket assembly and thread ferrule in (towards
idler) to increase tension on belt, out to decrease
tension.
