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 w/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 w/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 w/Shredder.
We recommend wearing gloves while using the Chipper w/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 w/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 w/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. 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 w/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 w/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 w/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 w/Shredder Hopper could damage the machine and/or cause injury.
Know how to stop the Chipper w/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 w/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 w/Shredder at any time.
Always operate the machine from the Operator Zone (see Figure 14 on page 12). Never pass or stand on the discharge side 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.

14 DR ®
9.5 Chipper w/Shredder
Using the Chipper Chute
The Chipper Chute is designed to chip thicker materials that the Shredder Hopper isn’t designed to handle. The revolving Chipper
Knife mounted on a Flywheel turns branches fed into the Chute into “chips”. The Chipper can chip twigs and branches ranging in size from 1/2" to 3" in diameter. Cut your materials into manageable lengths before feeding them into the Chipper Chute.
The Chipper is not self-feeding. Hold onto and slowly feed material into the Chipper Chute while paying attention to the engine speed. 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.
Overloading the Chipper Chute will cause the Engine speed to decrease. If the Engine bogs down, stop feeding material into the Chipper Chute and wait until the Engine returns to full speed before continuing.
Your DR 9.5 Chipper w/Shredder 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.
NEVER allow processed material to build up within 3" of the Discharge opening. Move the DR 9.5 Chipper w/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 9.5 Chipper w/Shredder finishes processing and discharging material before shutting the Engine off.
Using the Shredder Hopper
The Shredder Hopper can process hard wood branches up to1/2" in diameter and softer organic material up to 2-3/8” in diameter. You can shred most organic materials. A Guard (flap) is attached to the Hopper. You must push material past this flap (using a branch if necessary) in order to enter the main Shredding Chamber where revolving steel Hammers do the shredding.
The Hammers within the Shredding Chamber can tug suddenly at material fed into the Shredder Hopper. 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.
Due to the wide variety of materials that you can shred, and their very 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.
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 1/2".
Cut branches so they are shorter than (3) feet 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. The shredding capacity is 1/2" hard woody material. For clearing a clog, you can intermittently shred a larger stick up to 1" diameter.

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 24 ).
Knife Mounting Hole
5/16" 5/16"
Short Side Beveled Edge
Figure 24: New Knife
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 25 ), or if you are unable to remove dents or gouges with these guidelines, replace the Knife.

SOME STATES DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL
DAMAGES, SO THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.
THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU ALSO HAVE OTHER RIGHTS, WHICH VARY
FROM STATE TO STATE.
Daily Checklist for the DR 9.5 Chipper w/Shredder
To help maintain your DR 9.5 Chipper w/Shredder for optimum performance, we recommend you follow this checklist each time you use your Chipper w/Shredder.
Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all parts to cool.
Disconnect the Spark Plug Wire, keeping it away from the Spark Plug.
[ ] 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 w/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
Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all parts to cool.
Disconnect the Spark Plug Wire, keeping it away from the Spark Plug.
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 9.5 Chipper w/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 w/Shredder in a dry, protected place. If it is necessary to store the machine outside, after the
DR 9.5 Chipper w/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.
