Attaching the Hopper Assembly
• Remove the 8-3/8” long hex bolt and the hex nut
from the bottom of the inlet guide opening. See
Figure 2.
• Place the hopper assembly on the ground and hold
it in the position.
• Holding the hopper, push hopper pivot door down
inside the hopper.
• Slide the hopper assembly towards the chipper-
shredder housing so that the upper guide on the
hopper assembly slides under the stop washer on
each side of the inlet guide.
• Align the two holes (one on each side) of the lower
hopper with the two holes (one on each side) of the
inlet guide.
• Insert the hex bolt (that you earlier removed) from
the left through the hole on the hopper and the inlet
guide. Insert the hex nut onto the bolt from the other
side.
• Tighten the bolt till the lock nut is engaged. Make
sure to remove any side play from the bolt, but the
hopper should be able to pivot.
Figure 2

hold and lift it up till it clicks into position.
• To lower the hopper, hold the hopper by the hand-

washer on the inlet guide.

properly attaching this flap control rod to
the unit.

discharge opening. Insert hex bolt and spacer
