Protecting Yourself and Those Around You
THIS IS A HIGH-POWERED MACHINE, WITH MOVING PARTS OPERATING WITH HIGH ENERGY AT HIGH
SPEEDS. THE MACHINE MUST BE OPERATED SAFELY. UNSAFE OPERATION CAN CREATE A NUMBER OF
HAZARDS FOR YOU, AS WELL AS ANYONE ELSE IN THE NEARBY AREA. ALWAYS TAKE THE FOLLOWING
PRECAUTIONS WHEN USING THIS MACHINE:
•
•
•
•
ALWAYS WEAR PROTECTIVE GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHILE CHIPPING 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 HOPPER.
WE RECOMMEND WEARING GLOVES WHILE CHIPPING. BE SURE YOUR GLOVES FIT PROPERLY AND
DO NOT HAVE LOOSE CUFFS OR DRAWSTRINGS.
WEAR SHOES WITH NON-SLIP TREADS WHEN USING YOUR CHIPPER. 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 DR ROAD-TOWABLE CHIPPER.
USE EAR PROTECTORS OR EAR PLUGS RATED FOR AT LEAST 20 DBA TO PROTECT YOUR HEARING.
NEVER ALLOW PEOPLE WHO ARE UNFAMILIAR WITH THESE INSTRUCTIONS TO USE THE CHIPPER.
ALLOW ONLY RESPONSIBLE INDIVIDUALS WHO ARE FAMILIAR WITH THESE RULES OF SAFE

DISCHARGE OPENING, OR NEAR OR UNDER ANY MOVING PART WHILE THE MACHINE IS RUNNING.
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. IF IT BECOMES NECESSARY TO PUSH MATERIAL INTO THE
CHIPPER HOPPER, USE A SMALL DIAMETER STICK, NOT WITH YOUR HANDS.
•
KEEP BYSTANDERS AWAY FROM YOUR WORK AREA AT ALL TIMES. WOOD CHIPS EXIT THE CHIPPER
AT GREAT SPEEDS. TO BE SAFE, DO NOT OPERATE THE MACHINE NEAR SMALL CHILDREN OR PETS,
AND NEVER ALLOW CHILDREN TO OPERATE THE CHIPPER. STOP THE ENGINE WHEN ANOTHER
PERSON OR PET APPROACHES.
•
•
NEVER USE THE MACHINE WITH THE CHIPPER HOPPER OR DISCHARGE CHUTE REMOVED.
DO NOT OPERATE THE ENGINE WITH THE AIR CLEANER OR COVER OVER THE CARBURETOR AIR-
INTAKE REMOVED, EXCEPT FOR ADJUSTMENT. REMOVAL OF SUCH PARTS COULD CREATE A FIRE
HAZARD. DO NOT USE FLAMMABLE SOLUTIONS TO CLEAN AIR FILTER.
•
•
ALWAYS OPERATE THE MACHINE FROM THE OPERATOR ZONE (SEE FIGURE 9 ON PAGE 24). NEVER
PASS OR STAND ON THE DISCHARGE SIDE OF THE MACHINE WHEN THE ENGINE IS RUNNING OR
THE FLYWHEEL IS TURNING.
NEVER TRY TO PICK UP, MOVE, OR TRANSPORT THE MACHINE WHILE THE ENGINE IS RUNNING OR
THE FLYWHEEL IS TURNING.
•
•
THE MUFFLER AND ENGINE BECOME VERY HOT AND CAN CAUSE A SEVERE BURN; DO NOT TOUCH.
CLEAR THE AREA OF OBJECTS SUCH AS WIRE AND ROPE ETC. INSERTING THESE OBJECTS INTO THE
CHIPPER HOPPER COULD DAMAGE THE FLYWHEEL AND/OR CAUSE INJURY.

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 DR ROAD-TOWABLE 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. 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 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 WIRES,
KEEPING THEM AWAY FROM THE SPARK PLUGS TO PREVENT ACCIDENTAL STARTING.
•
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. IF REQUIRED, SEE YOUR AUTHORIZED DEALER FOR ENGINE GOVERNOR
ADJUSTMENTS.

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 28.
•
At engine start-up, the engine of your DR CHIPPER operates under no load until approximately
1200-1400 RPM, at which speed the Centrifugal Clutch engages and begins driving the Rotor
Assembly.
•
•
Proper Rotor speed is 2400-RPM +/- 200 RPM.
When viewed from the Chipper Hopper side, the Flywheel turns in a clockwise direction.
•
•
•
Only operate the DR ROAD-TOWABLE CHIPPER from the Operator Zone shown in Figure 9.
Keep proper balance and footing while operating the DR ROAD-TOWABLE CHIPPER.
ALWAYS stop the engine when leaving the Operating Zone (Figure 9) or when moving the machine.

Processing Material
•
•
•
•
ALWAYS WEAR PROTECTIVE GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHILE CHIPPING
TO PROTECT YOUR EYES FROM POSSIBLE THROWN DEBRIS.
AVOID WEARING LOOSE CLOTHING OR JEWELRY, WHICH MIGHT CATCH ON MOVING PARTS OR
THE MATERIAL FED INTO THE CHIPPER HOPPER.
WE RECOMMEND WEARING GLOVES WHILE CHIPPING. BE SURE YOUR GLOVES FIT PROPERLY
AND DO NOT HAVE LOOSE CUFFS OR DRAWSTRINGS.
WEAR SHOES WITH NON-SLIP TREADS WHEN USING YOUR CHIPPER. 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 DR ROAD-TOWABLE CHIPPER.
USE EAR PROTECTORS OR EAR PLUGS RATED FOR AT LEAST 20 DBA TO PROTECT YOUR
•
•
•
•
Your DR ROAD-TOWABLE 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.
•
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.
It is best to trim off any side twigs from the main branch that you are chipping.
Use caution with small diameter green saplings and branches less than 2" in diameter. Chip these
grouped or bundled together to provide support for each other. If the material is 2" or larger, feed
only one at a time into the Chipper Hopper.
•
Make sure the DR ROAD-TOWABLE 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.

Electric-Starting
1. Pull the Choke control (Figure 8 on page 23) out to the CHOKE position (leave in the RUN position if
the engine is already warm).
2. Move the Throttle to the FAST or RUN position (Figure 8 on page 23).
3. Turn the Key Switch to ON (Figure 8 on page 23) then to the START position until the engine starts,
then release. The key will snap back to the RUN position and the engine will continue to run.
4. As the engine warms up, slowly adjust the Choke to the Run position. Wait until the engine runs
smoothly before each Choke adjustment. For maximum performance, operate the engine with the
Throttle in the FAST or RUN position with the CHOKE pushed in to the RUN position.
Stopping the Engine
1. Move the Throttle control lever all the way to the SLOW or IDLE position and turn the Key to OFF.
2. Remove the Key for safety. The Key has a pressure lock that prevents it from vibrating loose during
operation. To remove the Key, push it in and then quickly and firmly pull it out. If the Key becomes
difficult to remove, spray FLUID FILM® or a similar non-conductive lubricant into the keyhole.
NOTE: Close the fuel Shut-Off Valve when transporting or storing the DR ROAD-TOWABLE CHIPPER.
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 Chipper Hopper is mounted on the side of the machine and is designed to chip wood only. The
revolving Chipper Knife mounted on a flywheel turns branches fed into the hopper into “chips”. The
Chipper can chip branches and vines ranging in size up to 4-1/2" 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 ROAD-TOWABLE
CHIPPER BEFORE USING THE MACHINE!
•
•
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 40.
Extremely hard knots will not process very well. Short stubs that have not self-fed through the Chipper
can be pushed 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 WIRES, KEEPING THEM AWAY FROM THE
SPARK PLUGS TO PREVENT ACCIDENTAL STARTING.
•
•
NEVER allow processed material to build up within 3" of the discharge chute opening. Move the DR
ROAD-TOWABLE 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!

Removing and Replacing the Chipper Knife
ROUTINELY CHECK THE CHIPPER KNIFE FOR SHARPNESS. USING A DULL KNIFE WILL DECREASE
PERFORMANCE AND CAUSE EXCESSIVE VIBRATION THAT WILL CAUSE DAMAGE TO THE DR ROAD-
TOWABLE CHIPPER ENGINE.
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 WIRES, KEEPING THEM AWAY FROM THE SPARK PLUGS.
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 17.

•
•
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 18), or if you are unable to remove dents or
gouges with these guidelines, replace the Knife.

1. Using a 5/16" Wrench, remove both Access Covers (Chipper and Drive Side) from the Chipper Box
(Figure 1 on page 15).
2. Rotate the Chipper Disk using a stick until the three (3) countersunk Allen Screws and Lock Nuts
attaching the Knife to the Flywheel are visible through the Access Openings.
3. Clean out the heads of the Allen Screws with an awl or sharp tool.
4. Insert a 3/16” Allen wrench into the head of a screw.
5. While holding the Allen wrench, remove the Lock Nut using a 1/2" socket.
6. Repeat Steps 4 and 5 for the remaining two (2) Allen screws.
7. Remove the dull or damaged Knife and visually inspect the Chipper Disk Slot and Knife mounting area
and be sure they are clean and that the replacement Knife will be able to mount flush against the
Chipper Disk.
8. Install a new or sharpened Knife and finger tighten the Allen screws and Lock Nuts (new hardware is
supplied with a new Knife) to hold the Knife to the Chipper Disk.
9. Using a 3/16" Allen wrench and 1/2" socket, tighten the center Screw and Nut, then tighten the outer
Screw and Nut, and finally tighten the inner Screw and Nut.

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 19). 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 WIRES, KEEPING THEM AWAY FROM THE SPARK PLUGS.

1. To prevent accidental Starter engagement, disconnect the battery at the negative terminal.
2. 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.
3. 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.
4. Tighten the Nuts and Bolts when the Wear Plate is in the correct position (Figure 19).
•
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 ANY OF THESE IS DETECTED, INSPECT THE MACHINE FOR DAMAGE,
OR ANY LOOSE PARTS. REPAIR OR REPLACE ANY DAMAGED PARTS AND TIGHTEN ANY LOOSE
PARTS BEFORE STARTING THE DR ROAD-TOWABLE CHIPPER.
•
IF AT ANY TIME IT BECOMES NECESSARY TO DISASSEMBLE THE CHIPPER FOR REPAIRS, THE
CHIPPER DISK MUST BE RE-INSTALLED IN EXACTLY THE SAME POSITION ON THE ROTOR SHAFT.
5. Re-connect the negative battery terminal wire and the spark plug wires.

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 WIRES, KEEPING THEM AWAY FROM THE SPARK PLUGS.
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
ROAD-TOWABLE CHIPPER Engine at less than full RPM.
NOTE: At engine start-up, the engine of your chipper operates under no load until approximately 1000-1200 RPM
for both the 18 and 19 HP models, 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 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 SHOES AND SPRINGS IN SETS. WHENEVER
SHOES ARE CHANGED, REPLACE ALL SPRINGS.

Battery Care
Proper care can extend the life of a battery. Follow these recommendations to ensure your battery’s best
performance and long life:
•
Do not allow the battery charge to get too low. If the machine is not used, charge the battery every 4 – 6
weeks. Operate the engine for at least 45 minutes to maintain proper battery charge.
•
•
Store an unused battery in a dry area that does not freeze.
Do not charge an already charged battery. In theory, you cannot overcharge our battery with a trickle
charger; however, when a battery is fully charged and the charger is still on, it generates heat that could
be harmful to the battery. A fully charged battery will read 12V-13.2V with a voltmeter.
•
Do not continue to crank your engine when the battery charge is low.
Charging the Battery
Operate the engine for at least 45 minutes to maintain proper battery charge. If the battery loses its charge,
you will need to use a trickle charger (like the DR Battery Charger) to recharge it. The charger should have
an output of 12 volts at no more than 2 amps.
•
•
At 1 amp, the battery may need to be charged for as long as 48 hours.
At 2 amps, the battery may need to be charged for as long as 24 hours.
To connect a battery charger to your DR ROAD-TOWABLE CHIPPER, follow the steps listed below.
1. Detach the two battery cables going to the battery on your machine.
2. Attach the black (-) battery charger wire to the battery negative (-) terminal, and attach the red (+)
battery charger wire to the battery positive (+) terminal.
3. Plug the battery charger into an outlet.
WHEN YOU ARE FINISHED CHARGING THE BATTERY, DISCONNECT THE CHARGER FROM THE
OUTLET FIRST, THEN DISCONNECT THE BATTERY CHARGER WIRES FROM THE BATTERY. IF YOU
LEAVE THE BATTERY CHARGER WIRES CONNECTED TO THE BATTERY, THE BATTERY WILL DISCHARGE
ITSELF BACK INTO THE CHARGER.

End of Season and Storage
•
•
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 WIRES, KEEPING THEM AWAY FROM THE SPARK PLUGS.
NEVER STORE THE DR ROAD-TOWABLE CHIPPER WITH FUEL IN THE FUEL TANK INSIDE A BUILDING
WHERE IGNITION SOURCES ARE PRESENT, SUCH AS HOT WATER AND SPACE HEATERS, CLOTHES
DRYERS AND THE LIKE. IF YOU ARE GOING TO DRAIN THE FUEL TANK, DO THIS OUTDOORS. ALLOW
THE ENGINE TO COOL BEFORE STORING IN ANY ENCLOSURE.
•
WHEN NOT IN USE, YOUR DR ROAD-TOWABLE CHIPPER SHOULD BE STORED OUT OF THE REACH OF
CHILDREN.
NOTE: Please refer to the Engine Owner's Manual for engine-specific procedures.
•
•
Change the oil (and oil filter, if applicable).
Remove the spark plugs and pour about 1 ounce of motor oil into each cylinder hole. Reinstall the
plugs and engage the electric starter for a few seconds. This will coat the pistons and seat the
valves to prevent moisture buildup.
•
•
•
Clean or replace the air filter(s).
Lubricate all grease fittings. See page 32.
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 ROAD-TOWABLE 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.
•
•
•
Check the Drive Belts for wear.
Check the Chipper Knife and Wear Plate for nicks and wear.
Remove the battery or store your DR ROAD-TOWABLE CHIPPER in a dry environment where the
temperature is between –10° F (–23° C) and +85° F (+23° C). Make sure the storage temperatures
will never be outside these limits.

2-Year Limited Warranty
Terms and Conditions
The DR® ROAD-TOWABLE CHIPPER is warranted for two (2) years against defects in materials or workmanship when
put to ordinary and normal consumer use; ninety (90) days for any other use. The engine manufacturer warrants the
engine separately.
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® ROAD-TOWABLE CHIPPER is fit
for ordinary purposes for which a product of this type is used. Country Home Products, Inc. however, limits the implied
warranties of merchantability and fitness in duration to a period of two (2) years in consumer use, ninety (90) days for
any other use.
The 2-Year Limited Warranty on the DR® ROAD-TOWABLE CHIPPER starts on the date the machine ships from our
factory. The 2-Year 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
manuals. The warranty holder is responsible for replacement of normally wearing parts such as the drive belt, knife, wear plate,
bearings, flex guards, and battery. Attachments and accessories to the machine are not covered by this warranty.
During the warranty period, the warranty holder is responsible for the machine transportation charges, if required. During the
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.
SOME STATES DO NOT ALLOW LIMITATIONS ON THE LENGTH OF IMPLIED WARRANTIES, SO THE ABOVE

Daily Checklist for the DR ROAD-TOWABLE CHIPPER
To help maintain your DR ROAD-TOWABLE 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.
[ ] BELT: Check the condition of the Drive Belts for nicks and cuts.
[ ] GENERAL CONDITION: Check the general condition of the machine, e.g.; nuts, bolts, welds etc.
