Although the instructions and warnings appearing in this
manual cover most normal operating conditions,
everyone using the chipper/shredder unit must also
always follow safe work practices while operating,
servicing, or handling the chipper/shredder unit under
any conditions not specifically covered in this manual.
SETTING UP
• Although most assembly has been done at the
factory , your chipper/shredder unit requires minor
assembly and the addition of engine oil before it can
be used. Nev er attempt to start or operate the unit
unless the chipper cone and shredder hopper have
been properly installed and engine oil has been
added.
• Perf orm the required assembly in an area where the
chipper/shredder can be handled comfortably . Nev er
attempt to assemble the unit unless the engine/base
assembly can be held or securely positioned for
assembly needs.
• Use proper hand tools for assembling the chipper/
shredder. Ne ver use tools such as adjustable openend wrenches that can slip off hardware as it’ s being
fastened. Never use toothed gripping pliers which
may damage hardware and make removal difficult.
• Always use only the hardware provided with this unit
for assembly. Never substitute parts, or mix the
proper position of parts during assembly . If a part is
missing, contact your local dealer for an exact
replacement.
• Assemble the unit in the sequence indicated in the
assembly instructions. Make sure all hardware is
properly tightened after assembly is completed and
before starting the unit.
• Make sure all required hardware has been installed.
Never attempt to start or operate the unit unless you
are sure that all required hardware has been used.
• Inspect the shredder hopper and chipper cone for any
debris, loose hardware, or other material that may
have f allen in during unpacking and assembly.
Always disconnect the spark plug wire from the
spark plug, before removing any objects.
• Never fill the fuel tank indoors! Gasoline vapors are
explosive, and can easily travel unnoticed to sources
of ignition, such as pilot lights or open flames on
water heaters, furnaces, stoves, or dryers, sparks
from electric motors and other electrical appliances,
3
SAFETY RULES
or unattended smoking materials. Contact with these
or any other ignition sources will cause an explosion
or fire, serious personal injury , and damage to
property and equipment.
• Never overfill the fuel tank. Fuel may run out of the
tank and contact hot surfaces on the chipper/
shredder motor and ignite, causing a fire and/or risk
of an explosion. Fill fuel tank to 1/2” below bottom of
filler neck only.
• Use only an approved container for fuel and always
handle the container with extreme care. Never smoke
while fueling the chipper/shredder or transporting the

CONTROLS & MAJOR COMPONENTS
OPERATING CONTROLS
Your new chipper/shredder has been designed for both
ease of use and lasting reliability, and features a
simplified control system that required just two operating
controls.
These two operating controls, the Choke and the
Throttle, are conveniently located on the chipper/
shredder engine where they can be easily adjusted to
start and run the unit under a variety of operating
conditions.
Choke
The choke controls the fuel to air ratio, and helps make
cold starts easier by providing a rich, easily ignited fuel
mixture.
Throttle
The throttle controls engine speed, and allows you to
conserve fuel when idling, or to run the unit at maximum
speed for optimal chipping and shredding performance.
MAJOR COMPONENTS
C. Bag
The two-bushel bag is standard equipment and attaches
in seconds for direct, one-step bagging.
D. The Support Leg and Wheels
The sturdy support leg and wide-track wheels give your
chipper/shredder a stable, three-point stance, allowing
solid positioning on virtually all surfaces. The large
wheel diameter and durable rubber tread design make
transporting the unit easy, and the low center of gravity
helps prevent tipping while moving over bumpy or
uneven terrain.
E. Fan/Rotor Housing
This housing assembly contains the chipper knives and
shredding hammers that process the materials you’ll be
chipping and shredding
F. Engine
The rugged, four-cycle, air cooled engine provides all
the power necessary to readily chip or shred a wide
variety of materials. See the engine service manual
shipped with your chipper/shredder for additional
information.
The major components of your chipper/shredder are:
• Shredder Hopper • Engine
• Discharge Chute • Chipper Cone
• Bag Shredding Hammers
• The Support Leg & Wheels • Chipper Knives
• Fan/Rotor Housing
Each of these major components serves a specific
function on the chipper/shredder. Please take a moment
and familiarize yourself with the name, location, and
function of these components so that you will better
understand the safety and operating instructions
provided in this manual. See Figure 6.
A. Shredder Hopper
The durable, low-profile design of the shredder hopper
makes shredding convenient, yet holds a full size load
of material for maximum processing capability.
B. Discharge Chute
The discharge chute ejects the material out of the
chipper/shredder, delivering processed materials to a
specific area. The pivoting deflector shield directs debris
down, while allowing soft materials to be ejected freely
from the machine.
G. Chipper Cone
The rugged chipper cone helps guide tree limbs and
branches directly into the chipper knives, and it’s unique
angled mounting helps pull the material in quickly for
aggressive chipping action.
Shredding Hammers (Not Shown)
The unique design of the patented free-swinging,
triangular shredding hammers and “J” hammers helps
pull material into the shredding chamber, and increases
volume-reduction efficiency more than most other
brands.
The revolutionary design of these triangular hammers
also provides 300% more shredding power than conventional fixed rectangular hammers, and since they can be
rotated, their six different usable cutting edges help
extend service life dramatically.
Chipper Knives (Not Shown)
Our chipper/shredder line also features high quality,
precision-tempered, solid steel chipper knives, which
can be sharpened again and again to extend their useful
life for many seasons to come.
