HOW TO SET-UP YOUR CHIPPER-SHREDDER
MAKE CERTAIN THE SPARK PLUG
WIRE IS DISCONNECTED AND MOVED
A
-ATTACHING THE CHUTE DEFLECTOR
• Remove the hand knobs and cupped washers from
each side of the discharge opening on the left side
of the chipper-shredder.
• Remove hex lock nut, two spacers and hex bolt
using two 7/16" wrenches from inside the hinge on
top of the housing assembly. Do not remove one
spacer from the hex bolt.
• Place the chute deflector in position on the dis
charge opening. Insert hex bolt and spacer through
hinge on chute deflector and housing (spacer fits
inside of hinge). See figure 2.
• Place second spacer over hex bolt, inside other
part of hinge. Secure with hex lock nut. Tighten
securely.
• Secure both sides of chute deflector to housing
using hand knobs and cupped washers (cupped side
of washers go against chute deflector).
-ATTACHING THE UPPER GUIDE ASSEMBLY
Grasp the upper guide assembly from the sides and
squeeze in and slide it over the inlet guide so the
edges are under the stop washers. Adjust so the
holes in the upper guide assembly are aligned with
the holes in the inlet guide. Insert the hex bolt, 8-3/8"
long through the upper guide assembly and the inlet
guide. Secure with flat washer and lock nut.
NOTE: Make certain the upper guide assembly can
pivot by lifting it up until it locks in the raised position.
If it does not pivot freely, loosen the hex lock nut a
turn or two and test.
-ATTACHING THE HOPPER ASSEMBLY
Your chipper-shredder has been shipped with the
upper leaf ramp section attached to the hopper
assembly. See figure 4. Attach the hopper assembly
to the upper guide assembly as follows. Be certain to
place heads of all truss machine screws inside of
hopper assembly.
• Remove one truss machine screw and nut from
each side of hopper assembly as shown in figure 4.
Push hopper pivot door down inside lower part
of hopper as you place hopper assembly (both
pieces) inside upper guide assembly. Replace
truss screws and nuts just removed, using the hole
shown in figure 4, one on each side. Tighten finger
tight only.
NOTE: You may have to squeeze in the sides of the
hopper to start the screws.
NOTE: If you have difficulty aligning the hole, loosen
the two screws on the upper end of the hopper
assembly.
• Place the six truss machine screws and nuts found
in hardware pack in the remaining holes of hopper
assembly, alternating sides of the unit and tighten
ing finger tight only.

Your chipper-shredder is equipped with a catcher bag
to catch the shredded material.
AWAY FROM THE SPARK PLUG
