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 ACTIVITY. NEVER
ASSUME THAT CHILDREN WILL REMAIN WHERE YOU LAST SAW THEM. ALWAYS FOLLOW THESE
PRECAUTIONS:
•
KEEP CHILDREN AND PETS OUT OF THE WORKING AREA AND 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.
Safety with Gasoline - Powered Engines
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.
FILL THE GASOLINE TANK OUTDOORS WITH THE ENGINE OFF AND ALLOW THE ENGINE TO COOL
COMPLETELY. DO NOT HANDLE GASOLINE IF YOU OR ANYONE NEARBY IS SMOKING, OR IF YOU
ARE NEAR ANYTHING THAT COULD CAUSE IT TO IGNITE OR EXPLODE. REINSTALL THE FUEL TANK
AND FUEL CONTAINER CAPS 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
THE MACHINE WITH 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 OR FLYWHEEL TURNING.
STOP THE ENGINE, WAIT FIVE (5) MINUTES TO MAKE CERTAIN THE FLYWHEEL AND ALL MOVING
PARTS HAVE COME TO A COMPLETE STOP AND COOL. DISCONNECT THE SPARK PLUG WIRE,
KEEPING IT AWAY FROM THE SPARK PLUG TO PREVENT ACCIDENTAL STARTING.
•
•
NEVER TAMPER WITH THE ENGINE’S GOVERNOR SETTING. THE GOVERNOR CONTROLS THE
MAXIMUM SAFE OPERATING 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 ENGINE DEALER FOR ENGINE GOVERNOR
ADJUSTMENTS.
TO REDUCE FIRE HAZARD, KEEP THE ENGINE AND MUFFLER FREE OF DEBRIS BUILD-UP.

SAE 30 - 28 oz. (.83L)
Unleaded gasoline, 1 US gal. (3.8 L)
Tip: To avoid confusion, we recommend leaving the caps on the fuel and engine oil fills and only removing
one cap each time when you are ready to pour gasoline or oil into the correct fill.
NOTE: Use SAE 30 high detergent oil classified “For Service SF, SG, SH, SJ” or higher. Do not use special
additives. Other types of oil could cause problems operating your machine. Please refer to your Engine
Owner’s Manual for detailed oil information.
1. Place the machine on a level surface and initially add 1/2 of the SAE 30 high detergent oil recommended
by the engine manufacturer and wait one minute for the oil to settle (Figure 2 on page 15).
2. Check the dipstick and continue adding a few ounces of oil at a time, rechecking the dipstick until the oil
reaches the fill mark. Be careful not to overfill (Figure 2 on page 15).
FILL GAS TANK OUTDOORS OR IN A WELL-VENTILATED AREA, AWAY FROM SPARKS, OPEN FLAMES, PILOT
LIGHTS, HEAT, AND OTHER IGNITION SOURCES.
3. Fill the gas tank with fresh, unleaded gas (with a minimum of 85 Octane), to approximately 1" to 1-
1/2" below the top of the fill neck to allow for fuel expansion. Be careful not to overfill and reinstall
the cap before starting the engine. See your Engine Owner’s Manual for more information.
NOTE: To refill the gas tank, turn the engine OFF and let the engine cool at least two (2) minutes before

Operation Notes
•
Visually check the Chipper Knife for damage each time you use the machine.
NOTE: Check for shaft movement while starting the engine. If the shaft does not turn, clean out the
Chipper as instructed on page 22.
•
At engine start-up, the engine of your DR 10 HP CHIPPER operates under no load until
approximately 1200-1400 RPM, at which speed the Centrifugal Clutch engages and begins driving
the Rotor Assembly.

If it becomes necessary to push material into the Chipper Hopper, only use a wood stick, NEVER
your hands, or any foreign material such as plastic or metal.
•
•
NEVER assume you know where the Chipper knife is. You do not know where it is. Always keep
hands out of the Chipper Hopper.
Keep area of discharge clear of people, animals, buildings, glass, or anything else that will obstruct clear
discharge, cause injury, or damage. Wind can also change discharge direction, so be aware.
•
•
•
ALWAYS operate the DR 10 HP CHIPPER from the Operator Zone (Figure 4).
Keep proper balance and footing while operating the chipper.
When feeding material into the Chipper Hopper, be extremely careful that pieces of metal, rocks, or
other foreign objects are not included. Personal injury or damage to the machine could result.
•
•
NEVER operate the machine without the Chipper Hopper and Discharge Chute properly installed.
If the cutting knife strikes a foreign object or if your machine should start making an unusual noise or
vibration, immediately stop the engine and wait five (5) minutes for all moving parts to come to a
complete stop and cool. After the machine has come to a complete stop proceed as follows:
- Disconnect the spark plug wire.
- Inspect for any damage and repair or replace any damaged parts before restarting and operating the
machine.
•
ALWAYS stop the engine when leaving the Operating Zone (Figure 4) or when moving the Chipper.

Your DR 10 HP CHIPPER 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 and how fast you can process
different materials.
•
•
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. Chip these grouped or bundled
together to provide support for each other.
•
Make sure the DR 10 HP CHIPPER finishes processing material in the Hopper before shutting the
engine off.
USE COMMON SENSE WHEN USING THE MACHINE. LEARN TO RECOGNIZE THE CHANGE IN SOUNDS
WHEN OVERLOADED. TURN OFF THE ENGINE IMMEDIATELY IF THE MACHINE BECOMES JAMMED TO
PREVENT DAMAGE TO THE DRIVE SYSTEM.

Starting and Stopping the Engine
1. When starting a cold engine; push the Choke Control lever to the right (CHOKE) and the Throttle
Control lever to the far right (Figure 3 on page 17).
2. Grasp the recoil starter handle and slowly pull until you feel resistance, then pull the cord with a
smooth accelerating motion to start the engine. One or two pulls usually starts the DR 10 HP
CHIPPER.
3. After the engine starts, slowly push the Choke Control lever (Figure 3 on page 17) to the left (RUN)
position. Wait until the engine runs smoothly before each Choke adjustment. For best engine
performance, it is recommended that the engine be operated with the Throttle in the fast (Rabbit)
position (Figure 3 on page 17).
4. To stop the engine, move the Throttle to the slow (Turtle) position allowing the engine to idle, then
move the lever to STOP (Stop Sign) position (Figure 3 on page 17).
5. Turn the Gas Shut-Off valve to the CLOSED position.
NEVER STOP THE ENGINE BY MOVING THE CHOKE LEVER TO THE CHOKE POSITION. THIS COULD
CAUSE AN ENGINE BACKFIRE RESULTING IN ENGINE DAMAGE.

Using the Chipper Hopper
The design of the Chipper Hopper mounted on the side of the machine is to chip wood only. The revolving
Chipper Knife mounted on a flywheel turns branches fed into the Chipper Hopper into “chips”. The Chipper
can chip twigs and branches up to 3-1/2" in diameter. Cut your materials into manageable lengths before
feeding them into the Chipper Hopper.
THE CHIPPER HOPPER MUST BE SECURELY BOLTED TO THE SIDE OF YOUR DR 10 HP CHIPPER BEFORE
USING THE MACHINE!
•
•
Feed the branch into Chipper Hopper keeping the branch at the same angle as Chipper Hopper.
As the branch becomes short and is inside the Chipper Hopper, finish processing it by pushing it into
the Chipper with the next branch.
•
•
•
If the branches to be processed are 1" or larger in diameter, you should feed only one (1) branch at a
time into the Chipper. You can feed more than one branch at a time into the Chipper if the branches
are smaller than 1" in diameter.
Do not force material into the Chipper. If the machine does not chip well, the Chipper Knife may need
to be sharpened or replaced, or the gap between the Knife and the Wear Plate needs adjusting. See
page 33.
Extremely hard knots will not process very well. Push any short stubs that have not self-fed through the
Chipper, through with the next branch to be chipped.
NEVER THROW REMAINING STUBS OR KNOTS INTO THE CHIPPER HOPPER; DAMAGE WILL RESULT.
•
•
Cut the material to be chipped into manageable lengths of no more than five or six feet long before
chipping them.
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.
IF YOU JAM THE MACHINE AND DO NOT STOP THE ENGINE, IT CAN DAMAGE THE MACHINE. THIS
DAMAGE CAN BE COSTLY AND MAY NOT BE COVERED UNDER WARRANTY. FOR THIS REASON, IT IS
IMPORTANT THAT YOU IMMEDIATELY STOP THE ENGINE IF THE MACHINE BECOMES JAMMED, WAIT
FIVE (5) MINUTES TO MAKE CERTAIN THE FLYWHEEL, AND ALL MOVING PARTS HAVE COME TO A
COMPLETE STOP AND COOL. DISCONNECT THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK
PLUG TO PREVENT ACCIDENTAL STARTING.
•
•
NEVER allow processed material to build up within 3" of the discharge chute opening. Move the DR 10
HP CHIPPER or the pile as needed. Failure to do so could result in unnecessary jamming of the
machine.
To move a pile of processed material, use a spade, rake, or long handle tool. NEVER use your hands or
feet!

Knife Sharpening
•
•
•
You should never attempt to sharpen the Chipper Knife freehand.
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.
Be sure not to overheat the Knife during sharpening because it will shorten the life of the Knife.
•
•
Take the Chipper Knife to a machine shop for proper sharpening.
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 5/16" measurement between the short side bevel edge and the Knife
mounting holes. See Figure 12.

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" (see Figure 13), or if you are unable to remove dents or
gouges with these guidelines, replace the Knife.

Adjusting the Knife to Wear Plate Gap
When you replace the Knife, check and set the clearance between the Knife and Wear Plate. Set this
clearance or gap to 1/16" (Figure 15). If the gap between the Wear Plate and the Knife is not set correctly,
you will have excessive vibration when chipping and the Knife will seem to be dull. The Wear Plate should
have a square edge and be free of dents or gouges. The Wear Plate can be hand sharpened. Be careful not
to overheat it during the sharpening process. This will change the characteristics of the steel and you will
then have to replace the Wear Plate.
BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION, STOP THE ENGINE, WAIT FIVE
(5) MINUTES TO ALLOW ALL MOVING PARTS TO COME TO A COMPLETE STOP AND COOL. DISCONNECT
THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK PLUG.

2. Rotate the Chipper Disk using a stick until the Knife is opposite the Wear Plate.
3. To adjust the Wear Plate Gap, loosen the three (3) 1/4" Nuts and Bolts while holding the Wear Plate in
place. Now you can slide the Wear Plate up or down (in or out) to achieve the correct gap setting.
4. Take the Gap Gauge and slide it between the Knife and Wear Plate. If the gap is set correctly, the Gap
Gauge will lightly touch both the Knife and Wear Plate. If the gap is too small, you will not be able to get
the Gauge between the Knife and Wear Plate. If the gap is too large, there will be excess room between
Gap Gauge, Knife, and Wear Plate.
5. Tighten the Nuts and Bolts when the Wear Plate is in the correct position (Figure 15).
6. Replace the Chipper Hopper.
AFTER ANY KNIFE OR WEAR PLATE MAINTENANCE OR ADJUSTMENT, ROTATE THE CHIPPER DISK BY
USING A WOODEN STICK AND WATCH AND LISTEN CAREFULLY FOR ANY UNUSUAL NOISES, CLICKING
OR VIBRATION. IF YOU DETECT ANY OF THESE, INSPECT THE MACHINE FOR DAMAGE, OR ANY LOOSE
PARTS. REPAIR OR REPLACE ANY DAMAGED PARTS AND TIGHTEN ANY LOOSE PARTS BEFORE STARTING

Removing and Replacing the Clutch
BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION, STOP THE ENGINE, WAIT FIVE
(5) MINUTES TO ALLOW ALL MOVING PARTS TO COME TO A COMPLETE STOP AND COOL. DISCONNECT
THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK PLUG.
The design of the Clutch on your machine is for rugged, dependable service, however, it is important to
understand the limitations of a Clutch. The Clutch design is to provide load free starting of the Engine, and
slippage under excessive overloading of the driven application. These features help protect the Engine from
damages such as broken crankshafts and starters. The Shoes and Springs on the Clutch are normal wear
items. If you notice decreased performance of the Clutch, check and replace them if necessary.
The Clutch obtains its power from the Engine RPM. The lower the engagement speed, and the higher the
maintained Engine speed, the more torque the Clutch can transfer to the driven unit. NEVER operate the
DR 10HP CHIPPER Engine at less than full RPM.
NOTE: At engine start-up, the engine of your chipper operates under no load until approximately 1100-1200
RPM, at which speed the centrifugal clutch engages and begins driving the rotor. Proper rotor speed is
2400-RPM +/- 200 RPM.
•
DO NOT 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. SEE YOUR AUTHORIZED DEALER FOR ANY ENGINE GOVERNOR ADJUSTMENTS.
•
•
BECOME FAMILIAR WITH SUCCESSFUL OPERATING CONDITIONS AND AVOID THOSE THAT CAN
OVERLOAD AND DAMAGE THE MACHINE.
DO NOT OVERLOAD OR ATTEMPT TO CHIP MATERIAL BEYOND THE MANUFACTURERS
RECOMMENDATION. PERSONAL INJURY OR DAMAGE TO THE MACHINE COULD RESULT. LEARN TO
RECOGNIZE THE SOUND OF THE MACHINE DURING AN OVERLOAD CONDITION. ONLY YOUR
OPERATOR EXPERIENCE WILL TELL YOU HOW FAST YOU CAN SUCCESSFULLY FEED MATERIAL INTO
THE MACHINE.
•
•
IF OVERLOADING OR ANY OTHER CAUSE JAMS THE MACHINE, STOP THE MACHINE IMMEDIATELY.
IF YOU JAM THE MACHINE AND DO NOT STOP THE ENGINE, IT CAN BURN THE DRIVE BELT AND/OR
RUIN THE CLUTCH. CLUTCH DAMAGE CAN BE COSTLY AND IT MAY NOT BE COVERED UNDER
WARRANTY. FOR THIS REASON, IT IS IMPORTANT THAT YOU IMMEDIATELY SHUT OFF THE
MACHINE IF IT BECOMES JAMMED.
THE CENTRIFUGAL CLUTCH ON THIS MACHINE IS PERMANENTLY LUBRICATED AND DOES NOT
REQUIRE OIL OR GREASE. IF, AFTER LONG PERIODS OF USE, THE DRUM WOBBLES EXCESSIVELY,
REPLACE THE DRUM ASSEMBLY. ALWAYS REPLACE THE SHOES AND SPRINGS IN SETS. WHENEVER
THE SHOES ARE CHANGED; REPLACE ALL SPRINGS.

Lubricate all grease fittings. See page 26.
Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole. Reinstall the
plug and pull the recoil starter rope until you feel strong resistance. This will coat the piston and
seat the valves to prevent moisture buildup.
•
•
Clean or replace the air filter.
Clean any dirt and debris from the cylinder head cooling fins, blower housing, debris screen and
muffler area of the engine.
•
•
If your engine has a fuel filter, replace it.
If your DR 10 HP CHIPPER 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.

For the purposes of all the above warranties, “ordinary and normal consumer use” refers to non-commercial residential use
and does not include misuse, accidents or damage due to inadequate maintenance.
Country Home Products, Inc. (home of DR® Power Equipment) certifies that the DR® 10 HP CHIPPER is fit for ordinary

Limited Warranty is applicable only to the original owner.
The warranty holder is responsible for the performance of the required maintenance as defined by the manufacturer's owner's
manuals. The warranty holder is responsible for replacement of normally wearing parts such as the drive belt, knife, Wear Plate,
bearings, and flex guards. Attachments and accessories to the machine are not covered by this warranty.

warranty period, warranty parts will be shipped by standard method at no charge to the warranty holder. Expedited shipping of
warranty parts is the responsibility of the warranty holder.

Daily Checklist for the DR 10 HP CHIPPER
To help maintain your DR 10 HP CHIPPER for optimum performance, we recommend you follow this
checklist each time you use your machine.
[ ] OIL: With the machine on a level surface, check the engine oil level with the dipstick and add more
if necessary (only add oil to the level indicated on the dipstick - DO NOT OVERFILL). Use
SAE 30 high detergent motor oil.
[ ] GAS: Fill the gas tank with clean, fresh, unleaded gasoline.
[ ] ENGINE AIR COOLING SYSTEM: It is very important to keep the engine clean of debris. Remove
grass and other built-up materials from the air intake screen
before, during, and after you chip. Regularly remove debris
from the blower housing and cooling fins. A dirty engine retains
heat and can cause damage to the internal engine parts.
[ ] CHIPPER HOPPER: Inspect the Chipper Hopper for accumulated debris.
[ ] KNIFE: Inspect the Chipper Knife for tightness, nicks and wear.
[ ] WEAR PLATE: Check the Wear Plate for nicks; the edge should be square.
[ ] BELT: Check the condition of the Drive Belt for nicks and cuts.
[ ] GENERAL CONDITION: Check the general condition of the machine, e.g.; nuts, bolts, welds etc.
