Coat the top of the ring around the discharge
opening with general purpose grease. See figure 28.
Place the discharge chute (facing forward) onto the
ring. Place the anti-rotation bracket on top of the
chute flange, aligning it with the holes on the right
hand side of the flange. Attach the three chute
keepers (right side up as shown) to the bottom of
the flange using six 1/4" x 1" hex bolts, 1/4" flat
washers and 1/4" hex lock nuts. Tighten carefully
so that the nuts are snug but do not dig into the
plastic chute keepers. See figure 28.
Place the plastic cap onto the short end of the anti-
rotation bracket. See figure 28.
Position the crank rod spiral so that it does not rub
against the bottoms of the notches in the chute
flange. Tighten the nuts. See figure 27.
Check if the crank rod rotates the chute freely. If
not, loosen by 1/4 turn each of the six hex bolts
holding the chute keepers to the chute flange.
Secure the control cables to the crank rod support
tube using a nylon tie.
