1.With the snowthrower drive belt installed, trunnion (A, Figure 11) should be between marks (G) on spring tension bracket (B) for correct belt tension.
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 step 2.
