Check belt tension:
To quickly check the tension on the belt, loosen the upper jam nuts on the engine
mount. If the engine rises 1/16”-1/8” off the lower jam nuts, the belt is at approximately the correct
tension. If the engine does not lift slightly, lower the bottom jam nuts to set the gap and tighten the upper
jam nuts tight.

Unbolt the exit spout assembly and hinge outward to rest on the angled rests. Stay clear of the blades,
unlock and turn the chipper disk as necessary to position the chipper blade in the blade access area. See
