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.
Protecting Yourself and Those Around You
Safety for Children and Pets
Safety with Gasoline - Powered Machines
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.
Never
assume that children will remain where you last saw them. Always follow
these precautions:
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.
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. Keep away from heat, open flames,
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 first. 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.

11.5 CHIPPER SHREDDER
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 and wait 5 minutes for parts to cool.
Disconnect the Spark Plug wire, keeping it away from the Spark Plug, to prevent accidental starting 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.
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, property damage, and will
void your warranty.
Never use the machine with the Chipper Chute, Shredder Hopper, Blowback Guards, or Discharge Deflector 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 could 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 7
on page 13). Never pass or stand on the discharge side of
the machine when the Engine is running or the Flywheel is turning.
If the machine starts making an unusual noise or vibration, Shut down the Engine and wait 5 minutes for parts to cool,
disconnect the Spark Plug wire, keeping it away from the Spark Plug to prevent accidental starting before making adjustments
or repairs. 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.

The Hammers within the Shredding Chamber can tug suddenly at material fed into the Shredder Hopper. Wear Gloves and do
not hold on tightly to branches and vines and do not feed material straight down into the Hopper with your arm pointing
downward toward the opening. Instead, keep your arms parallel to the ground and several inches above the top edge of the
Hopper as you drop the material into the opening.
Using the Chipper Chute
The Chipper can chip twigs and branches ranging in size from 1/2" to 4" in diameter. Cut your materials into manageable lengths
before feeding them into the Chipper Chute. The revolving Chipper Knife mounted on a Flywheel turns branches fed into the
Chute into “chips”. NOTE: Use the Shredder Hopper as described in the next section for hard wood branches less than 3/4" in
diameter and softer organic material up to 4-1/2" in diameter.
Hold onto and slowly feed material into the Chipper Chute. Do not force material or allow material to be pulled too quickly into
the Chipper.
Larger diameter hardwood or extremely hard knots may not process as well as other materials. Discard larger diameter or
harder branch stubs before they become too short to control their feed rate.
Keep a moderate feed rate to prevent overloading the machine. Overloading the Chipper Chute will cause the Engine speed to
decrease and may result in clutch failure.
Your Chipper can process dry or green material. Green material will process quicker and easier than dry material. Soft wood
processes easier than hard wood.
If the machine does not chip well, the Chipper Knife may need sharpening or may need to be replaced.
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 Chute. 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 Chute.
Shred green or very leafy material smaller than 3/4" diameter (like pine boughs) through the Shredder Hopper instead of the
Chipper Chute.
Using the Shredder Hopper
The Shredder Hopper can process hard wood branches up to 3/4" in diameter and softer organic material up to 4-1/2" in
diameter. You can shred most organic materials. A Guard (flap) is attached to the Hopper. Material must go past this flap in
order to enter the main Shredding Chamber where revolving steel Hammers do the shredding. Use a Stick to push the material
past the flap if needed.
Due to the wide variety of materials that you can shred and their different physical characteristics, only feed limited quantities of
any material into the Shredder Hopper at first. Increase the amount and length of material if you find that the material is
processing without any difficulty. Your judgment and operator experience is very important.
ALWAYS pay attention to the discharge to confirm that material is exiting the machine at the same rate it is entering. If
material builds up inside the cutting chamber instead of discharging - stop feeding more material and wait for the material to
discharge. If the material does not discharge, see the “Removing a Clog” section of you DR Chipper Shredder Safety and
Operating Instruction manual.
Be sure not to overload the machine by feeding too much material into the Hopper at one time. If you hear the speed of the
Engine decreasing, stop feeding material into the machine at once. Do not resume feeding the machine until the Engine has
returned to full speed.
You can feed several small branches into the Shredder Hopper at once providing their combined diameter is less than 3/4".
Cut branches so they are shorter than 3 feet long to make them more manageable.
Allow green materials to dry before processing or alternate processing and discharging green/wet materials with dry materials
to avoid clogging. If wet materials begin to clog, shred a stick to clear the material through. If the clog still is not cleared, see
the “Removing a Clog” section on the next page.

3. Rotate the Screen down to gain access to the cutting chamber (Figure 11).
Note: If the Screen will not rotate down freely, the nearby bolts can be loosened
slightly.
4. Clear all clogged material from the machine.
5. Rotate the Screen back into the operating position and reinstall the
hardware. Note: Make sure the bolt goes through the screen rather than just
behind it.
6. Start the machine and allow any remaining material to discharge.
7. If you have been shredding wet/green materials the clog may be near the
shredder housing inlet. Shred a wood stick of up to 1" diameter to clear the
clogged wet material.
8. If the clog does not clear repeat the above process.
9. Be certain the cutting chamber is clear before trying to process more
material.
NEVER allow processed material to build up within 3" of the Discharge opening. Move the DR 11.5 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 use your
hands or feet!
Make sure the DR 11.5 CHIPPER SHREDDER finishes processing and discharging material before shutting the Engine off.
Before performing any maintenance procedure or inspection, stop the
Engine, wait five minutes to allow all parts to cool. Disconnect the Spark
Plug Wire, keeping it away from the Spark Plug.

take about 3-5 pounds of force. The belt should move 1/4" to 1/2" when
tensioned properly. If the belt deflection is not within this range, follow
Steps 3-7 to adjust the belt tension.
3. Loosen the two, left side Engine Mount Locknuts using a 1/2" Wrench
(Figure 17).
4. Loosen the two, right side Engine Mount Bolts and Locknuts using two 1/2"
Wrenches (Figure 18).
5. Adjust the Tension Bolt using a 1/2" Wrench (Figure 17) until the belt is at
the correct tension as describe in Step 2.
Note: If the Tensioner Bolt has reached its limit and the Belt is still not tensioned
properly, the belt has stretched beyond its service limit and must be replaced. To
replace the belt, refer to the applicable steps in the following section “Replacing the
Belt”.
6. When the Belt tension adjustment is complete, tighten all four Engine Bolts,
then retighten the Tension Bolt about 1/8 turn.

11.5 CHIPPER SHREDDER
Replacing the Chipper Knife
The DR 11.5 CHIPPER SHREDDER is shipped with a sharp Chipper Knife and
depending upon material being chipped we've found it can remain acceptably
sharp for 40 plus hours. When you notice diminished feeding, it is time to
replace the knife. You may also choose to have the knife sharpened instead as
described on the next page.
Tools and Supplies needed:
1/2" Wrench
3/16" Allen Wrench
Awl
Gloves
1. Remove the top Screen Bolt and Locknut using two 1/2" Wrenches (Figure
24).
2. Rotate the Screen down to gain access to the cutting chamber (Figure 25).
3. Loosen the Locknuts on the Access Plate and slide it to the side and remove
(Figure 26).
4. Rotate the Flywheel until the Knife is centered in the opening (Figure 27).
5. Clean out the heads of the Allen Screws with an awl or sharp tool.
6. Insert a 3/16” Allen wrench into the head of the screws and a 1/2" Wrench
on the Locknuts to remove the three Locknuts and Screws.
7. Carefully remove the dull or damaged Knife and visually inspect the Knife
mounting area and be sure they are clean. Metal burrs may need filing so
that the replacement Knife will be able to mount flush against the Flywheel.
8. Install a new or sharpened Knife and finger tighten the Allen Screws and
Locknuts.
Note: New Allen Screws and Locknuts are provided with each new Chipper Knife.
9. Using a 3/16" Allen Wrench on the Screw and a 1/2" Wrench on the
Locknut, tighten the hardware to secure the Chipper Knife.
10. Double-check all three Screws for tightness one more time.
11. Reinstall the Access Plate.
12. Rotate the Screen back into the operating position and reinstall the
hardware. Note: Make sure the bolt goes through the screen rather than just
behind it.

Knife Sharpening
You should never attempt to sharpen the Chipper Knife freehand; take the Knife to a machine shop for proper sharpening.
It is extremely important to consistently maintain the 45-degree angle for proper performance.
Excessive heat generated during the sharpening process will damage Knives and weaken the metal.
How many times a Knife can be sharpened is determined by how much material needs to be taken off to sharpen or to
compensate for dents or gouges.
A new Chipper Knife has a 5/16" measurement between the short side bevel edge and the Knife mounting holes (Figure 28).
The knife should never be sharpened to the extent that more than 3/32" is taken off this measurement.
Once this measurement is below 7/32" (Figure 29), or if you are unable to remove dents or gouges with these guidelines,
replace the Knife.

Daily Checklist for the DR 11.5 CHIPPER SHREDDER
To help maintain your DR 11.5 CHIPPER SHREDDER for optimum performance, we recommend you follow this checklist
each time you use your CHIPPER SHREDDER.
[ ] Check the Engine oil and Fuel Tank level.
[ ] Check that Engine is clean of debris.
[ ] Remove any unprocessed material from the Chipper Chute and Shredder Hopper.
[ ] Check the general condition of the CHIPPER SHREDDER, e.g.; nuts, bolts, welds, etc.
[ ] Check Tire Pressure and wear.
[ ] Check the Chipper Knife for tightness, nicks and wear.
[ ] Check the Blowback Guards and Discharge Guard for wear and damage.
End of Season and Storage
Change the Engine oil.
Clean or replace the Air Filter.
Check the Chipper Knife and Hammers for nicks and wear.
Remove any debris wrapped around the Hammers/Spacers.
If your DR 11.5 CHIPPER SHREDDER will be idle for more than 30 days, we recommend using a gas stabilizer. This will
prevent sediment from gumming up the Carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the
tank. Completely fill the tank with fresh, unleaded gas and add the appropriate amount of stabilizer or gasoline additive.
Run the Engine for a short time to allow the additive to circulate. Close the Fuel Shut-Off Valve to prevent carburetor
overflow and leakage.
Clean the exterior of the unit to remove all dirt, grease, and any other foreign material. To prevent rust, touch up painted
surfaces that have been scratched or chipped.
Be sure all nuts, bolts, and screws are securely fastened.
Remove the Spark Plug and pour about 1 ounce of motor oil into the Cylinder hole. Replace the Plug and crank the Engine
over a couple of times using the Pull Cord. This will coat the piston and seat the valves to prevent moisture buildup.
If possible, store the CHIPPER SHREDDER in a dry, protected place. If it is necessary to store the machine outside, after
the DR 11.5 CHIPPER SHREDDER has cooled, cover the machine with a suitable protective cover that does not retain
moisture. Do not use plastic as this material cannot breathe; it also allows condensation to form, which will cause your
machine to rust.
Before performing any maintenance procedure or inspection, stop the Engine, wait five minutes to allow all parts to cool.
Disconnect the Spark Plug Wire, keeping it away from the Spark Plug.
