• Read these Assembly & Operating Instructions and the engine manufacturer's owner's
®
manual before you use the DR
engine and service recommendations to ensure the best performance from your machine.
TRIMMER/MOWER™. Become familiar with the controls,
• Inspect the area you'll be working in for hidden objects such as large rocks, logs, rope, wire,
garden tools, etc., and remove these obstacles before mowing. Do not attempt to mow over
obstacles as this could damage the machine and cause injury.
Operating the Machine Safely
• Only use the DR
growth as specified in this manual.
• Use only manufacturer-recommended replacement parts and accessories.
• Never bend, cut, fit, weld, or alter the DR
to your machine could cause personal injuries and property damage, and may void your
warranty.
• ALWAYS shut off the engine and remove the spark plug wire prior to making any
adjustments to the machine. If you have to stop to remove grass or debris from the underside
of the deck, ALWAYS disconnect the spark plug wire first.
• The exhaust area on the engine becomes very hot. Allow the engine to cool before doing
maintenance or making adjustments.
®
TRIMMER/MOWER™ for trimming and mowing grass, weeds, and other
®
TRIMMER/MOWER™ in any way. Modifications
• When operating over uneven terrain and slopes, use EXTREME CAUTION and ensure solid
and firm footing at all times.
• Use extra caution when mowing in wet, slippery conditions.
• As with any trimmer, the tips of the cutting cords on the DR
throw sticks, small stones, gravel, and bits of debris over long distances at great velocity.
The faster the cutting cords are spinning, the farther debris may be thrown. Do not travel
over loose materials such as gravel or mulch with the trimmer head spinning. Doing so could
cause personal injury or property damage from thrown objects.
DR® TRIMMER/MOWER™ Safety & Operating Instructions ii
®
TRIMMER/MOWER™ can
• Turn off the engine whenever you leave the operating position. Never leave the engine
running when refueling, changing cords or checking, cleaning or working on the machine.
• Never allow children or animals near the work area. Keep at least 50 feet clear of
bystanders, and always turn the machine off when someone approaches to avoid causing
injury from thrown objects.
• Never allow children or people unfamiliar with these instructions to use the DR
TRIMMER/MOWER
• Be cautious when using your DR
hoses. It is possible that these and other debris can become wound around the line plates of
the machine, potentially damaging the bearings or injuring the operator.

• Use the machine only in daylight or good artificial light.
• Never operate the machine with a damaged shield or without the shield in place.
• Do not operate the machine when under the influence of alcohol or medication.
• Watch for traffic when mowing near roadways.
Safety with Gasoline-Powered Machines
• Do not run the engine in an enclosed area or without proper ventilation.
• Store all fuel in containers specifically designed for this purpose. Plastic containers are more
likely to prevent sediment and condensation problems.
• Refuel outdoors only, and do not smoke while refueling or operating the machine.
• If gas is spilled, 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 near an open flame or spark with gas in the tank.
• Do not change the engine governor settings or modify the engine speed.
• Some state and local regulations require the use of a spark arrester on gasoline powered
engines. Contact your local fire marshal or forest service for specific information
pertaining to your area. If you are required to use a spark arrester, please contact one
of our Customer Service Representatives for assistance in obtaining and installing one.
Warning to All California and Other Users
Under California and Washington State laws, and the laws of some other states, you are not
permitted to operate an internal combustion engine using hydrocarbon fuels without an engine
spark arrester. All DR® TRIMMER/MOWERS shipped to California and Washington state are
provided with spark arresters. Failure of the owner/operator to maintain this equipment in
compliance with state regulations is a misdemeanor under California law and may be in violation
of other state and/or federal regulations. Contact your local fire marshal or forest service for
specific information in your area.

Setting Up Your Trimmer
Step 1: Connect the Battery Wires (Electric-Starting models only)
To prevent the battery from discharging
during shipment, all electric-starting
trimmers are shipped with at least one
battery wire disconnected.
Connect the black wire by pushing the
plastic connector onto the negative (-)
terminal (Figure 1). See the red wire for
comparison.
Figure 1
Step 2: Add Oil and Gas
Reminder: To avoid confusion, we
recommend leaving the caps on the fuel
and oil fills until you are ready to pour
either gasoline or oil into the correct fill.
1. Use SAE30 High Detergent oil. Add
approximately 15 ounces of oil and
wait one minute for the oil to settle.
Check the dipstick, then continue
adding small amounts of oil and
rechecking the dipstick until it reaches
the full mark (Figure 2). Do not
overfill.
Important! To get an accurate
reading when checking the oil level
the machine should be on a level
surface, and the dipstick should be
screwed down.
Please refer to your engine
manufacturer's owner's manual for
detailed oil information.
2. Fill the gas tank to within 1/4 inch of
the top with fresh, unleaded gas. See
your engine manufacturer's owner's
manual for detailed fuel
recommendations.
WARNING!
THIS MACHINE IS SHIPPED WITHOUT OIL!
TRACES OF OIL MAY BE IN THE
RESERVOIR FROM FACTORY TESTING, BUT
YOU MUST ADD OIL BEFORE STARTING
THE ENGINE. FILL THE RESERVOIR
SLOWLY, CHECKING THE DIPSTICK
FREQUENTLY TO AVOID OVERFILLING.

Stopping the Engine
Move the throttle control lever (Figure 3) back to the STOP position.
Note that on Electric-Starting models the key does not stop the engine. You must throttle down.
The key has a pressure lock that prevents it from vibrating loose during operation. If you wish 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 comparable lubricant into the keyhole.
Engaging the Trimmer Head
Bring the bail bar (Figure 3) toward you and grip it together with the handlebar. Keep holding
the bail bar to the handlebar. The cutting cords will now be rotating and will continue to rotate
until you release the bail bar.
Stopping the Cords Spinning
Release the bail bar from the handlebar. The trimmer head will stop spinning while the engine
continues to run.
If the trimmer head keeps spinning after the bail bar is released you may need to adjust the
trimmer control cable. See page 20.
Using the Parallel Trimming
Action (PTA
The DR® TRIMMER/MOWER'S PTA™ Feature
allows the machine to move in a straight line while
the trimmer head is both pivoted and tilted to the left
for better access to fence lines and other obstacles
(Figure 6). This feature allows you to trim in
difficult areas without having to pull the machine
back and forth.
The cutting cords extend beyond the wheel base
when in the PTA
cut under obstacles. The trimmer head and the
cutting cords also tilt slightly when in the PTA™
mode so you can edge and trim along gardens, paths
and driveways.
IMPORTANT! When using PTA™ mode, you should

Cutting Cords
WARNING! Always turn the engine off when installing or changing cutting cords.
Figures 9 and 10 illustrate how the cords are installed on the line plates. It may look
complicated, but once you've done it a couple of times it's really very easy. There are two sets of
installation points on each line plate, 180 degrees apart. One set of holes is for larger cord (155
mil) and is marked with large arrows. The other set of holes accommodates smaller cord (130
mil) and is marked with small arrows. Always install two cords opposite each other for the best
performance.
Caution! Running the trimmer with only one cord installed, or cords installed at other than 180
degrees can cause excessive vibration and may damage the machine.
Figure 9
Figure 10
DR® TRIMMER/MOWER™ Assembly & Operating Instructions 6
Cord Installation
The standard cord installation method is shown in Figures 11-13. This is how your trimmer is
shipped from the factory.
1. Insert the ends of the cords into the
openings in the line plate, as shown in
Figures 10 and 11. There are different
sized arrows at the insertion points to
indicate what size cords fit the holes.
2. Push the cord through until it comes
out the center hole in the line plate as
shown in Figure 12. Adjust the cords
so the tips are even.
3. Pull the cords through the loop and
push the loop up into the line plate
groove above them, as shown in
Figure 13. Then pull the cords tight.

TRIMMER/MOWER™ Safety & Operating Instructions 7
Figure 13
Cord Tips
Two thicknesses of cutting cord ship with your DR® TRIMMER/MOWER™: Heavy-Duty (130
mil) and Extra Heavy-Duty (155 mil). Because conditions and vegetation vary so much,
experiment with the different cord weights in order to discover what works best for your
particular mowing and trimming situations. Here are a few things to keep in mind:
• If you buy cutting cord in rolls, cut it in 23" lengths.
• The best trimming performance will usually come from using the smallest diameter cord
(which is still capable of cutting the material at hand), combined with the fastest engine
speed. When more power is needed for thicker growth such as berry canes, brambles, thistles
or ragweed, you may want to use the Extra Heavy-Duty (155 mil) cord in combination with
the highest engine speed.
• Be careful not to move too fast through thick growth. If there are woody weeds in the
material being cut, the cutting cords may wrap around the stalks they cannot cut, and pull
away from the trimmer head. Ease the ends of the cord into heavy growth.
Reminder: The ends of the cutting cords do the cutting.
)
• IMPORTANT! When using the PTA
the bottom four line plates only. Installing cutting cords in the upper line plates may cause
the cord to hit the wheel when in PTA
™
feature you should install the cutting cords in one of
™
mode.
• To increase the cutting swath, install each cord slightly offset, with one end of the cord about
an inch longer than the other. Be careful not to offset the cords by more than an inch. Doing
so may cause the cords to hit the wheels.
• Please note that installing more than two cords at a time does not improve trimming
performance—in fact, it can lessen it. Adding additional cords creates drag on the trimmer
head, robs the engine of power and may cause wrapping. Installing two cords, 180 degrees
apart, is the best method for optimal trimming performance.
• When replacing cords, do it one at a time and use the old cord to mark the position for the
new cord to be installed.
• If the cord breaks off flush at the line plate, use the new cord to push the old cord out.
• Storing the cord in a plastic bag with a damp sponge or cloth will help keep it pliable. You
can also soak your cutting cord in a bucket of room temperature water for a few days before
use to make it more pliable.
DR® TRIMMER/MOWER™ Assembly & Operating Instructions 8
Adjusting the Cutting
Height
Adjusting the cutting height is easy.
Simply install the cutting cords in the line
plate that gives you the desired height.
Cutting heights range, in 1/2" increments,
from 1-1/2" when using the bottom line
plate, to approximately 4" when using the
top line plate (Figure 14).
IMPORTANT! When using PTA™ mode,
you should install the cutting cords in one
of the bottom four line plates only
the upper line plates may cause the cords
to hit the wheel.
. Using
Mow-Ball™ Support
Allow the front end of the machine to rest
lightly on the Mow-Ball™ Support as you
are trimming. The Mow-Ball™ Support
should glide on the ground as you
maneuver the machine.
In order to achieve the best and smoothest
cut, do not lift up on the handlebar while
operating your DR® TRIMMER/
MOWER™. Lifting the handlebar causes
weight to be forced down on the MowBall™ Support. This uses more energy,
slows down the cutting, and produces a
less than satisfactory cut. Ideally, the
Mow-Ball™ Support should lightly rest on
the ground while the wheels balance most
of the weight of the machine (Figure 15).
Figure 14
Figure 15
Adjusting the Handlebar
The correct handlebar height depends on many factors for each individual. However, it is crucial
to find a height that allows the Mow-Ball™ Support to glide along the ground and remain
balanced without the operator having to push down or pull up on the handlebar.
At the proper height, your hands should rest at a comfortable level and the front end of the
trimmer should roll easily on the Mow-Ball
You may find you like different handlebar heights for different mowing conditions.
®
DR
TRIMMER/MOWER™ Safety & Operating Instructions 9
™
Support as shown in Figure 15.
There are two ways to adjust the height of the handlebar:
1. Loosen both of the adjustment knobs
and move the handlebar up or down as
needed. It's important that the
adjustment is the same on both sides.
Use the notches on the adjusters
(Figure 16) to measure how many
teeth you've moved away from the
center. When you've found a
comfortable height, tighten the
adjustment knobs securely.
2. For additional height adjustment
options, there are two holes in the
upper and lower handlebars where the
adjustment knobs are located. Most
people start with the handlebars set in
the lower holes of both the upper and lower handlebar. You can adjust the height up or down
by removing the adjustment knob assembly and repositioning the handlebars to a higher or
lower hole. Be sure the notches in the two adjusters line up when you reassemble them
(Figure 16).
Figure 16
Please Note: When you change the position of the handlebar, you will need to adjust the PTA™
lever up or down to maintain proper PTA function. Please see page 21.
Obstacles
Many Owners like to mow easy, open
areas with their regular riding or walkbehind mower, then they finish trimming
all the odd and hard-to-reach spots with
the DR® TRIMMER/MOWER™ (Figure
17).
The DR® TRIMMER/MOWER™
discharges cut material to the right.
Always try to cut and trim with the uncut
tall grass or weeds on the left.
Suggestion: For the neatest
)
appearance, do your trimming first,
discharging clippings away from borders
and shrubs, then do your mowing.
• Always check your work area before trimming and remove any debris that might tangle or
damage the machine.
Figure 17
• If you do run into debris and the trimmer gets tangled, turn off the engine and disconnect the
spark plug wire before attempting to untangle the machine.
DR® TRIMMER/MOWER™ Assembly & Operating Instructions 10
• DO NOT run the machine over gravel driveways or over loose stones or mulch with the
trimmer head spinning. The engine's power can easily throw stones, sticks and other debris at
great velocity, which could cause personal injury or property damage.
Heavy Growth
Take your time in heavy growth. Be sure
to keep the uncut material to your left,
maintaining a clear discharge area to your
right (Figure 18). If the machine can't do
it all in one pass, overlap half of the
cutting swath. And if the grass is very
thick and heavy, try raising the trimmer
head off the ground a few inches by
pushing down on the handlebar. Cut the
material at this height, and then make a
second pass with the Mow-Ball™ Support
on the ground.
EASE the DR® TRIMMER/MOWER™
into denser growth. If the material is too tough or woody and can't be cut, the cutting cords will
wrap around it, wear down or even break off. Sometimes, growth is so heavy that it can't be
mowed in rows. A back and forth "vacuum cleaner" motion often works better when tackling
really tough material.
Figure 18
Wet Conditions
Because there is no housing to restrict the flow of cut
material, you can also use your DR® TRIMMER/
MOWER™ to mow wet or heavy growth. The DR® can
be used in damp conditions—after a rain or in the early
morning dew—without clogging or stalling. You can
also mow wet areas such as ditches and around ponds
(Figure 19).
Very Dry Conditions
When trimming and mowing in very dry conditions, be
extra cautious of cut grass, chaff, weeds, seeds, etc.,
accumulating on the engine, especially around the recoilstarter housing and engine cooling fins. Frequently
remove debris from the recoil guard on top of the engine
and the cooling fins on the front of the engine to prevent
overheating and engine damage. Please see the engine
manufacturer's owner's manual for more detailed
information on cleaning the air intake and cooling
system on the engine.
Figure 19
®
DR
TRIMMER/MOWER™ Safety & Operating Instructions 11
Slopes
You can trim and mow on slopes up to 20 degrees. Continuous use on slopes steeper than 20
degrees may deprive the engine of adequate lubrication, and damage components.
Windrows
The DR® TRIMMER/MOWER'S cutting cords cut even tall grass in just one pass, so you can
collect clippings and leaves for mulch without raking. The machine ejects cut material to its
right, so you can use it like a lawn broom to make windrows for easy clean-up.
Firebreaks
Use the DR® as a labor-saving tool to cut material when creating firebreaks.
End-of-Season Garden Clean-Up
The DR® is perfect for cutting down dead perennials, annuals and wildflowers, saving you hours
of hand pruning and deadheading. You can also re-cut downed material a second time to create
mulch for garden beds.
DR® TRIMMER/MOWER™ Assembly & Operating Instructions 12
Maintenance
*** For engine maintenance, please refer to the engine
manufacturer's owner's manual. ***
IMPORTANT!: Because of the conditions the DR® TRIMMER/MOWER™ is used in,
air filters and oil should be changed more frequently than is recommended in your
engine manufacturer's owner's manual. Please follow these recommendations:
Paper Air Cartridge: Should be replaced every 25 hours of operation. Replace
more frequently if operating in extremely dry and dusty conditions.
Oil: Should be drained and replaced after the first 5 hours, and every
subsequent 25 hours of operation.
Regular Maintenance
Regular maintenance is the way to ensure the best performance and long life of your machine.
Below is a list of recommended maintenance procedures. Follow the instructions in this manual
and your engine manufacturer's owner's manual.
WARNING: Always allow the engine to cool completely and remove the spark plug wire
before performing any maintenance procedure.
1. Clean any debris from the top and bottom of the machine, cylinder head fins, blower housing,
finger guard, debris guard, filter and muffler areas with a brush or rag.
2. Replace the paper air filter and clean the foam filter (Tecumseh engine only) every 25 hours
of operation. More frequently if operating in extremely dry and dusty conditions.
3. Replace the oil after the first 5 hours and every subsequent 25 hours of operation.
4. Clean the spark plug and replace it if needed.
5. Check the Mow-Ball™ Support assembly and clean out any debris.
6. Lubricate the engine throttle cable, trimmer control cable, and idler pulley with FLUID
FILM® or a similar lubricant.
™
7. Check the Mow-Ball
8. Replace broken or frayed cutting cords.
9. Inspect the belt for fraying or stretching. Replace it if necessary.
10. Check the bolts and nuts on the bearing housing assembly. If they are loose, tighten them.
Check all the bolts and nuts occasionally throughout the season to be sure they're secure.
Support and line plates for wear.

TRIMMER/MOWER™ Safety & Operating Instructions 13
Battery Care
(Electric-Starting Models Only)
Proper care can extend the life of a battery. Follow these recommendations to ensure your
battery's best performance and long life:
• Do not continue to crank the engine with a low battery.
• Try to keep the battery at full charge to maximize its life. If the machine is not used, the
battery should be charged every three months. See below for charging information.
• Store an unused battery in a dry area that does not freeze.
• Do not charge an already charged battery. In theory, our battery cannot be overcharged 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.
Automobile batteries last for years because they are recharged every time you drive your car—
usually on a daily basis. An Electric-Starting DR
battery while you operate it continuously for about 45 minutes or more. However, if you run

• A whirring noise coming from the starter.
• A grinding noise coming from the starter.
• No noise at all.
DR® TRIMMER/MOWER™ Assembly & Operating Instructions 14
What to do
:
• Check that the battery is fully charged. A fully charged battery should read about 12 volts.
Disconnect the battery from the wiring harness and then put a volt tester on the battery. If
you need to charge the battery, follow the directions above.
• Check all cable connections.
• The wiring harness consists of a set of wires that lead from the ignition switch to the battery.
Disconnect and reconnect the battery wires (black to black and red to red) and check the wire
connections at the key switch.
• Call one of our Technical Service Representatives TOLL-FREE 1(800)DR-OWNER(376-
9637) for assistance.

To Adjust the Belt Tension through the Trimmer Control
Cable
If the trimmer head stops spinning when the bail bar is engaged and the machine is operating
under a heavy load, the belt may be too loose and the trimmer control cable may need to be
adjusted to put more tension on it. The adjuster is located on the right handlebar, just above the
throttle control lever.
Before making any adjustments to the trimmer control cable, check that the belt is mounted on
the correct side of the idler pulleys (see page 18, Figure 25), and is not frayed, worn or stretched.
Tools Needed:
• (2) 1/2" open-end or adjustable wrenches
WARNING! Before performing any maintenance procedure, the engine should be stopped
and the spark plug wire disconnected.
To increase tension on the belt:
1. Loosen the upper control cable
adjustment nut, leaving about 1/8" of
space between the nut and bracket
(Figure 31).
2. Gently grip the metal end of the black
cable with pliers, making sure you DO
NOT crimp it. At the same time,
tighten the lower nut until it is flush
and snug against the bracket (Figure
31).
If the trimmer head keeps spinning after
the bail bar is released the belt may be too
tight.
To decrease tension on the belt:
Repeat the above steps, except this time loosen the lower nut, then tighten the upper nut.

Daily Checklist for the DR® TRIMMER/MOWER™
To help maintain your DR® for optimum performance, we recommend you
follow this checklist each time you use your machine.
9 GAS: Fill the gas tank with clean, fresh, unleaded gas.
9 OIL: Check the oil level with the dipstick and add more if necessary (only add
oil to the level indicated on the dipstick—do not overfill). Use SAE30 high
detergent oil.
9 SPARK PLUG: Clean the spark plug and replace if needed.
9 AIR FILTER: A clean air filter will mean a much easier-starting and better
running engine. You should replace the paper air filter after every 25 hours of
use, more frequently if you are trimming and mowing in dusty conditions.
9 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 mow. Regularly remove debris from the
blower housing and cooling fins. A dirty engine retains heat and can cause
damage to the internal engine parts.
9 BELT: Check the belt for wear, proper alignment and tension.
9 CUTTING CORDS: Replace broken or frayed cords.
9 MOW-BALL
™
SUPPORT: Check the Mow-Ball™ Support for wear.
