IMPORTANT SAFETY INFORMATION

Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are ammable and vapors are explosive.
When storing extra fuel be sure that it is in an appropriate container and away from any re hazards.
Prevent re and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the American Society for Testing &Materials.
ALWAYS ll fuel tank outside in a well ventilated area. NEVER ll your fuel tank with fuel indoors.
(Examples include: basement, garage, barn, shed, house, porch, etc.) NEVER ll tank near appliances
with pilot lights, heaters, or other ignition sources. If the fuel has to be drained, this should be done
outdoors. The drained fuel should be stored in a container specically designed for fuel storage or it
should be disposed of carefully.
NEVER remove the fuel cap or add fuel with the engine running. Stop engine and allow to cool before
lling.
ALWAYS wipe up excess (spilled) fuel from engine before starting. Clean up spilled fuel immediately. If
fuel is spilled, do not start the engine but move machine and fuel container from area. Clean up spilled
fuel and allow to evaporate and dry after wiping and before starting.
Allow fuel fumes/vapors to escape from the area before starting engine.
Test the fuel cap for proper installation before starting and using engine.
ALWAYS run the engine with fuel cap properly installed on the engine.
During storage, keep machine so gas cap is up. NEVER siphon fuel by mouth to drain fuel tank.
When storing gasoline or equipment with fuel in the tank, store away from furnaces, stoves, water heaters
or other appliances that have a pilot light or other ignition source because they can ignite gasoline vapors
NEVER ll containers inside a vehicle or on a truck bed with a plastic bed liner. Always place containers
on the ground away from your vehicle before lling.
Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible,
then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser
nozzle.

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. Check all hardware (bolts, screws,
etc) before every use for tightness to be sure machine is in safe working condition. Upon start-up and
shut-down, you may hear the metal-to-metal sound of the triangular hammers and J-hammers positioning
themselves on the rotor. This is normal. If this sound continues after the machine has reached full speed,
contact your dealer or XtremePowerUS for an inspection of the unit. Overloading the equipment will shorten
its life, and can cause mechanical failures
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 rst 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.
CHIPPER OPERATION
The shredder is designed to shred light brush, leaves, and other soft but bulky organic waste. As material
(no larger than 1/2 inch in diameter) is loaded into the shredder hopper it is pulled into the path of the
triangular and J-hammers by air ow.
SHREDDER OPERATION
Select an area with rm, 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.
OPERATING LOCATION
Refer to engine manual for information on adding oil.
ADDING OIL
TO AVOID SERIOUS PERSONAL INJURY FROM ROTATING CUTTING BLADES, KEEP
HANDS OUT OF INLET WHILE MACHINE IS RUNNING.
GASOLINE IS HIGHLY FLAMMABLE AND MUST BE HANDLED WITH CARE. NEV-
ER 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.
DO NOT USE GASOLINE CONTAINING METHANOL, GASOHOL CONTAINING MORE
THAN 10% ETHANOL, GASOLINE ADDITIVES OR WHITE GAS BECAUSE ENGINE/
FUEL SYSTEM DAMAGE COULD RESULT.
ENGINE IS SHIPPED FROM FACTORY WITHOUT OIL. YOU MUST ADD ENGINE OIL
BEFORE STARTING ENGINE.
1. Remove the fuel cap. (SEE FEATURES AND CONTROLS)
2. Fill the tank. Do not overll. Leave room in the tank for fuel expansion. Refer to your engine manual
for specic fuel recommendations.
3. Install and hand tighten the fuel cap.
ADDING FUEL
OPERATION

1. See engine manual for start up instructions.
2. Ensure engine is running full throttle before beginning chipping operation. On some engines, the throttle
may not be adjustable.
STARTING THE ENGINE
1. See engine manual for shut down procedure.
2. Stopping the engine is the only way to stop the rotor from turning. With engines equipped with an adjustable
throttle, move the throttle to the SLOW position and wait for engine to be running a slow RPM. Then switch
to STOP ENGINE as shown in the engine manual.
STOPPING THE ENGINE
• 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
feed them into the chipper cone.
CHIPPING 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.
SHREDDING TIPS:
Perform engine maintenance and storage measures listed in the engine owner’s manual. This includes
draining the fuel system, or adding stabilizer to the fuel.
STORAGE
NOTE: DO NOT store a fueled unit in an enclosed structure. (SEE GASOLINE FIRES AND HANDLING
FUEL SAFETY).
Check all uid levels. Check all maintenance items.
• Perform all recommended checks and procedures found in the engine owner’s manual.
• Allow the engine to warm up for several minutes before use.
