Coat the top of the ring around the discharge
opening with general purpose grease. See figure 14.
Place the discharge chute (facing forward) onto the
discharge opening, aligning the crank rod spiral
with the notches in the chute flange.
Attach the three chute keepers (right side up as
shown in figure 14) and the anti-rotation bracket to
the bottom of the chute flange. Use six 1/4" x 1"
hex bolts, 1/4" flat washers and 1/4" flanged lock
nuts. Tighten carefully so that the plastic parts are
not deformed. See figure 14.
Place the plastic grip onto the back end of the anti-
rotation bracket. See figure 14.
Position the chute crank assembly so that the crank
rod spiral does not rub the bottoms of the notches
in the chute flange and then tighten the nuts left
loose in figure 13.
Check if the crank rod rotates the chute freely. If
not, loosen by 1/4 turn each the six flanged nuts
holding the chute keepers to the chute flange.
