2. Turn belt tension handle (C) to move trunnion (A) for-
ward or rearward until it is between marks (G).
3. If trunnion cannot be placed between marks, loosen
capscrew (D) and reposition idler pulley (E) as nec-
essary. The pivot bracket (F) should be perpendicu-
lar to the hitch. Retighten capscrew (D) and repeat
