Safety Rules and Information
Moving Parts
This equipment has many moving parts that can injure you or
someone else. However, if you follow all the rules in this book,
the unit is safe to operate.
The chipper/shredder has spinning blades that can amputate
hands and feet. Do not allow anyone near the equipment while
it is running! Do not place hands or feet in the hopper or
chipper cone, or discharge chute.
Thrown Objects
This unit discharges debris at high speeds. Always wear protective goggles
and do not operate without the debris bag in place. Also, do not allow anyone
in the area while the unit is running! If someone does enter the area, shut the
unit off immediately until they leave. Organize the work area prior to starting
work.
Fuel and Maintenance
Gasoline is extremely flammable. Its vapors are also extremely flammable
and can travel to distant ignition sources. Gasoline must only be used as a
fuel, not as a solvent or cleaner. It should never be stored any place where
its vapors can build up or travel to an ignition source like a pilot light. Fuel
belongs in an approved, plastic, sealed gas can, or in the fuel tank with the
cap securely closed. Spilled fuel needs to be cleaned up immediately.
Proper maintenance is critical to the safety and performance of your unit.
Be sure to perform the maintenance procedures listed in this manual,
especially periodically testing the safety system.

while starting or operating the chipper/shredder.
Never lean directly over the machine.
16. Always stand to the side of the chipper cone when
feeding tree limbs and branches into the unit, as tree
limbs, branches, and harder woods may kick back
while being chipped.
17. Always keep hands out of the chipper cone and
shredder hopper when feeding materials. Never wrap
fingers tightly around branches as you are feeding
them into the unit, as a sudden inward surge could
pull your hands and arms into the unit.
18. Never allow material to build up in the discharge area
or shredding chamber, as this may cause new
material being fed into the machine to kickback with
sufficient force to injure you or other bystanders.
19. Never allow material to build up around the engine
during chipper/shredder operation. This could result
in a fire, or overheating of the engine.

10
Operation
General Operating Safety
Be sure to read all information in the Safety and
Operation sections before attempting to operate this unit.
Become familiar with all of the controls and how to stop
the unit.
Upon start-up and shut-down, you may hear the metalto-metal sound of the triangular hammers and Jhammers positioning themselves on the rotor. This is
normal. If this sound continues after the machine has
reached full speed, contact your dealer for an inspection
of the unit. Overloading the equipment will shorten its
life, and can cause mechanical failures.
Chipper Operation
The chipper is designed to handle tree limbs and
branches up to approximately 3” (7,6 cm) in diameter.
The chipping knives also permit the processing of course
organic matter like corn stalks. Tree branches must be
inserted large-end first into the chipper cone. Since
occasional kick-backs may occur, always stand off to the
side of the unit. Allow the self-feeding action of the unit
to draw the sticks in.
Shredder Operation
The shredder is designed to shred light brush, leaves,
and other soft but bulky organic waste. As material is
loaded into the shredder hopper it is pulled into path of
the triangular and J-hammers by air flow.
Vacuum Attachment (Optional)
In addition to the chipper cone and hopper, loose debris
may be processed by the Vacuum hose adapter kit.
Leaves may be raked directly into the leaf tray where
vacuum action will draw them into the shredder. For
hard-to-reach areas, the nozzle and hose assembly may
be used. The strength of the Vacuum may be changed
using the rotating sleave on the nozzle.
Operating Location
Select an area with firm, level ground, covered by dirt or
grass. Do not operate on wet or slick surfaces, or near
bystanders. Locate and organize the materials to be
processed so that you don’t have to walk in front of the
inlet or discharge openings, and so you have adequate
room to work safely.
WARNING
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do not
allow open flame, smoking or matches in the
area. Avoid over-filling and wipe up any spills.
WARNING
To avoid serious personal injury from rotating
cutting blades, keep hands out of inlet while
machine is running.
DANGER
The exhaust from this product contains carbon
monoxide gas. Carbon monoxide is a colorless,
orderless, and tasteless gas that can cause
dizziness, nausea, unconsciousness, or even
brain damage and death if inhaled for prolonged
periods.
Operate the unit outdoors in a well ventilated
location only. Keep children, pets, and
bystanders away.
Failure to follow these instructions may result in
serious injury or death.
Do not use gasoline containing METHANOL,
gasohol containing more than
10% ETHANOL, gasoline additives, or white
gas because engine/fuel system damage
could result.
11
Stopping the Engine
NOTE: In the event of an emergency the engine can be
stopped by setting the throttle control to STOP.
1. Slide the throttle control fully left to the STOP
position.
NOTE: Upon start-up and shut-down, you may hear the
metal-to-metal sound of the triangular hammers and Jhammers positioning themselves on the rotor. This is
normal.
2. After the engine has stopped moving, remove the
spark plug wire and remove any debris from the unit
and engine.
Processing Materials
Most materials to be processed can be handled more
efficiently by following these tips.
Chipping Tips:
• Prune branches down close to the main branch to
make feeding them into the chipper cone easier.
• Large, hard, dried tree branches that resist chipping
can be processed by rotating them as you alternately
insert and retract them.
• If the material to be chipped is extremely hard, kicks
back forcefully when being fed into the chipper cone,
or cannot be easily controlled, remove the material
immediately and set it aside.
• If additional force is required to insert materials into
the chipper, the blades probably need to be
sharpened. Consult the Troubleshooting and Repair
section of this manual, or see your authorized dealer.
• Maintain control of the materials you are feeding to
prevent them from whipping around.
• Do not insert short pieces of material into the chipper
cone by hand. Use a larger piece of material to force
them into the chipper cone.
Shedding Tips
• Don’t overload the shredder by dumping large
volumes of material into the hopper opening.
• Alternate loads of wet and dry material to prevent the
discharge from becoming plugged.
• Never use any object to force material into the
shredding chamber. It could get caught in the
shredding hammers and damage the unit.

The cutting edges of the shredding hammers may
eventually wear out requiring rotation of the hammer or
replacement if all cutting edges have been dulled.
Triangular hammers can be rotated twice after the first
edge dulls, then flipped over once and rotated again for a
total of 6 edges. J-hammers can be flipped over once for
a total of two cutting edges.
To rotate the shredding hammers:
1. Turn the engine off and wait for all moving parts to
stop.
2. Disconnect the spark plug wire and secure it away
from the spark plug.
3. Detach the shredder hopper from the rotator housing
(Figure 12).
4. Remove the rotator cover by removing the hardware
that secures it to the main housing (Figure 13).
5. Note the assembly sequence of the hardware used to
secure the hammers (Figure 14). Using a 5/16” allen
wrench remove the socket head capscrew (A) and
related hardware.
7. Inspect the hammers (G, H), spacer tubes (D, F), and
hardware. If the spacer tube (D, F) shows signs of
wear, replace it. Inspect and flip, or replace the
hammers (G, H).
8. Reassemble the hammers, spacers, washers, and
capscrews. Torque the socket head capscrews (A)
to 30-35 ft. lbs. (41-47 N.m.)Refer to Figure 14 for
