Note: The weight of the Engine should be enough to tension the Belts properly but

depending on hardware looseness and cleanliness of Engine Mount pivot
area, you may need to push down slightly to aid in proper tension. The Belt
performs best with a slight amount of slack to allow for some slippage when
the Wedge encounters a tough log. Too much tension may stall the engine or
slip the belt on the engine pulley.

6. Install the new Belt and adjust tension as needed (Figure 33).
7. Tighten the two Engine Mount Bolts that are at the center of the machine

(shown) first and then tighten the outer two Bolts (Figure 32).

8. Reinstall the Guard (Figure 31).
