ROTARY BELT TENSIONER
The rotary belt tensioner system uses a 9/16"-headed nut
and a 15/16" or 1" nut to set belt tension by positioning an
arm between the tensioner pulley and the tensioner base.
Ridges on the base mark the amount of tension.
Adjust to 3-1/2 notches on the tensioner:
1. Loosen the 9/16" nut.
2. Rotate the tensioner nut clockwise until the desired
belt tension is achieved.
3. Tighten the 9/16"nut.
