DISCHARGE CHUTE DEFLECTOR
To adjust, loosen then retighten hardware to desired
deflector drag force.
DISCHARGE CHUTE
If Chute does not stay in position while operating,
tighten nut on carriage bolt at pivot point to increase
tension on spring.
Smooth and easy rotation of properly lubricated chute
with crank is obtained by adjusting pinion and flat gear
teeth so they mesh together.
Adjust, using adjustment slots in pinion bracket which
is secured to chute strap.
The chute bracket and gear strap are also slotted for
vertical adjustment of the discharge chute. Loosen
mounting nut and move discharge chute up or down so
that chute ring is approximately centered between
retainer clip and lower ring. Retighten.
RUNNERS

Raising or lowering runners controls distance scraper
blade (auger/impeller housing) is held above surface
being cleared.
