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.
Allow the Engine to cool completely before storing in 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.

General Safety (continued)
Never place any part of your body in the CHIPPER/SHREDDER Hopper(s), 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/SHREDDER Hopper(s),
use a small diameter stick, NOT WITH YOUR HANDS.
Keep your face and body back from the CHIPPER/SHREDDER Hopper(s) 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 from the CHIPPER/SHREDDER Hopper(s).
Allow only one person to operate the CHIPPER/SHREDDER at any time.
Always operate the machine from the Operator Zone (see Figure 10
of the machine when the Engine is running or the Rotor 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 Rotor is turning.
Before performing any maintenance or inspection procedure on the CHIPPER/SHREDDER, shut the Engine OFF, remove the
Spark Plug Wire, and keep it away from the Spark Plug.

Processing Material
Read and understand the warnings listed in “Chapter 1 General Safety Rules” before operating this CHIPPER/SHREDDER.
Your DR CHIPPER/SHREDDER can process dry or green material.
Green material will process quicker and easier than dry material.
Soft wood processes easier than hard wood.
Your operator experience will teach you how different materials chip/shred and how fast you can process different materials.
Most materials process well with the standard screen provided with the DR CHIPPER/SHREDDER.
It is best to trim off any side twigs from the main branch that you are chipping.
When chipping branches, sometimes a tail will remain at the end of a branch. To avoid this, rotate the branch while feeding it
into the Chipper Hopper. Rotating the branch as you feed it into the machine will improve chipping performance.
Use caution with small diameter green saplings and branches less than 1" in diameter. Chip these grouped or bundled together
to provide support for each other. If the material is 1" or larger, feed only one at a time into the Chipper Hopper.
Make sure the DR CHIPPER/SHREDDER finishes processing material in the Hopper(s) before shutting the Engine off.
Using the Chipper Hopper
The Chipper Hopper is mounted on the side of the machine and is designed to chip the larger, heavier materials that the Shredder
Hopper isn’t designed to handle. The revolving Chipper Knife mounted on a Rotor turns branches fed into the Hopper into
“chips”. The Chipper can chip twigs and branches ranging in size from 1" to 2-1/2" in diameter. Cut your materials into
manageable lengths of no more than five or six feet long
before feeding them into the Chipper Hopper.
The Chipper Hopper must be securely bolted to the side of your DR CHIPPER/SHREDDER before using the machine!
Feed the branch into Chipper Hopper keeping the branch at the same angle as the Chipper Hopper.
As the branch becomes short and is at the outside edge of the Chipper Hopper, finish processing it by pushing it in with the
next branch.
Do not force material into the Chipper. If the machine does not chip well, the Chipper Knife may need sharpening or to be
replaced.
Extremely hard knots will not process very well. Push any short stubs that have not self-fed through the Chipper, with the next
branch to be chipped.
Never throw remaining stubs or knots into the Shredder Hopper; damage will result.
Overloading the Chipper Hopper will cause the rotor speed to decrease. If you hear the Engine RPM decreasing, stop feeding
material into the Chipper Hopper until the Engine has returned to full speed.
NEVER allow processed material to build up within 3" of the Discharge opening. Move the DR CHIPPER/SHREDDER or the
pile as needed. Failure to do so could result in unnecessary jamming of the machine.
To move a pile of processed material, first shut off the Engine, and use a spade, rake, or long handle tool; NEVER
hands or feet!
If you jam the machine and do not stop the Engine, it can damage the machine. This damage can be costly and not covered
under warranty. See “To Free a Jammed Flywheel” on page 16.
