Protecting Yourself and Those Around You
This is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely. Unsafe
operation can create a number of hazards for you, as well as anyone else in the nearby area. This machine can crush, grind, cut,
and sever parts of your body if they enter the inlet or discharge area of your Chipper Shredder. Always take the following
precautions when using this machine:
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and
themselves.
Always wear protective goggles or safety glasses with side shields while using the Chipper Shredder to protect your eyes from
possible thrown debris.
Avoid wearing loose clothing or jewelry, which can catch on moving parts or the material fed into the Chipper Shredder.
We recommend wearing gloves while using the Chipper Shredder. Be sure your gloves fit properly and do not have loose
cuffs or drawstrings.
Wear shoes with non-slip treads when using your Chipper Shredder. If you have safety shoes, we recommend wearing them.
Do not use the machine while barefoot or wearing open sandals.
Wear long pants while operating the Chipper Shredder.
Use ear protectors or earplugs rated for at least 20 dba to protect your hearing.
Keep bystanders at least 100 feet away from your work area. Stop the engine when another person or pet approaches.
Safety for Children and Pets
Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the
machine and the chipping/shredding activity.
these precautions:
Never
assume that children will remain where you last saw them. Always follow
Keep children and pets at least 100 feet from the working area and ensure they are under the watchful care of a responsible
adult.
Be alert and turn the machine off if children or pets enter the work area.
Never allow children to operate the Chipper Shredder.
Safety with Gasoline - Powered Machines
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline. Always follow these precautions:
Never run the Engine in an enclosed area or without proper ventilation as the exhaust from the Engine contains carbon
monoxide, which is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open
flame, and out of the reach of children.
Replace rubber Fuel Lines and Grommets when worn or damaged and after 5 years of use.
Fill the Gasoline Tank outdoors with the Engine off and allow the Engine to cool completely. Don't handle gasoline if you or
anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the Fuel Tank Cap and
Fuel Container Cap securely.
If you spill gasoline, do not attempt to start the Engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.

Safety with Gasoline - Powered Machines (Continued)
To safely store, allow the Engine to cool completely before moving into any enclosure. Never store a machine that has gas in
the tank, or a Fuel Container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
Never make adjustments or repairs with the Engine running. Shut down the Engine, disconnect the Spark Plug wire, keeping
it away from the Spark Plug to prevent accidental starting, wait 5 minutes before making adjustments or repairs.
Never tamper with the Engine’s Governor setting. The Governor controls the maximum safe operation speed and protects
the Engine. Over-speeding the Engine is dangerous and will cause damage to the Engine and to the other moving parts of the
machine. If required, see your authorized dealer for Engine governor adjustments.
Keep combustible substances away from the Engine when it is hot.
Never cover the machine while the Muffler is still hot.
Do not operate the Engine with the Air Cleaner or the Carburetor Air Intake Cover removed. Removal of such parts could
create a fire hazard. Do not use flammable solutions to clean the Air Filter.
The Muffler and Engine become very hot and can cause a severe burn; do not touch.
General Safety
Operating this Chipper Shredder safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation
can create a number of hazards for you. Always take the following precautions when operating this machine:
Your Chipper Shredder is a powerful tool, not a plaything. Exercise extreme caution at all times. The machine is designed to
chip wood and shred most organic materials. Do not use it for any other purpose.
Thoroughly inspect the area in which you will be working and remove all foreign objects. Look for rope, wire, etc., and remove
these objects before chipping/shredding. Inserting these objects into the Chipper Shredder Hopper could damage the
machine and/or cause injury.
Know how to stop the Chipper Shredder quickly; see “Stopping the Engine” in Chapter 3.
Never operate your unit on a slippery, wet, muddy, or icy surface. Exercise caution to avoid slipping or falling.
See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by DR
Power Equipment.
Never use the machine without ensuring that all guards and shields are in place.
Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the Chipper Shredder. This
includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will
void your warranty.
Never use the machine with the Chipper Chute, Shredder Hopper, Blowback Guards, or Discharge Guard removed.
Never place any part of your body in the Chipper Chute, Shredder Hopper, discharge opening, or near any moving part while
the machine is running. Keep the area of discharge clear of anything that will obstruct a clear discharge. Wind can also
change discharge direction, so be aware. If it becomes necessary to push material into the Chipper Chute or Shredder
Hopper, use a small diameter stick, NOT YOUR HANDS.
Keep your face and body back from the Chipper Chute and Shredder Hopper to avoid accidental bounce back of any material.
Do not allow an accumulation of processed material to build up in the discharge area as this will prevent proper discharge
and can result in kickback.
Allow only one person to operate the Chipper Shredder at any time.
Always operate the machine from the Operator Zone (see Figure 14
of the machine when the Engine is running or the Flywheel is turning.
If the machine should start making an unusual noise or vibration, shut down the Engine, disconnect the Spark Plug Wire,
keeping it away from the Spark Plug to prevent accidental starting, wait 5 minutes, then inspect for damage. Vibration is
generally a warning of trouble. Check for damaged parts and clean, repair, and/or replace as necessary.
Never tamper with safety devices. Check their proper operation regularly.

Never try to pick up, move, or transport the machine while the Engine is running or the Flywheel is turning.
For safe loading up ramps carefully PULL the machine with the Shredder Hopper hand holds. For safe unloading down
ramps, guide the machine from behind with the hand holds so it goes down the ramps and you follow.
Before performing any maintenance or inspection procedure on the Chipper Shredder, shut the Engine OFF, wait 5 minutes
for machine to cool, remove the Spark Plug Wire keeping it away from the Spark Plug.
Never allow people who do not understand and/or have not read this Safety and Operating Instructions Manual to use the
Chipper Shredder. Allow only responsible individuals who are familiar with these rules of safe operation to use your machine.
Never overload or attempt to Chip or Shred material beyond the manufacturer’s recommendation. Personal injury or damage
to the machine could result.
While using the Chipper Shredder, don't hurry or take things for granted. When in doubt about the equipment or your
surroundings, stop the machine and take the time to look things over.
Never operate the machine when under the influence of alcohol, drugs, or medication.
Use the machine only in daylight.
Stay alert for hidden hazards or traffic.
Keep all nuts and bolts tight and keep the equipment in good operating condition.
