Protecting Yourself and Those Around You
THIS IS A HIGH-POWERED MACHINE, WITH MOVING PARTS OPERATING WITH HIGH ENERGY AT HIGH
SPEEDS. 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. ALWAYS TAKE THE FOLLOWING
PRECAUTIONS WHEN USING THIS MACHINE:
ALWAYS WEAR PROTECTIVE GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHILE MOWING TO
PROTECT YOUR EYES FROM POSSIBLE THROWN DEBRIS. GOGGLES ARE PROVIDED WITH YOUR DR
TRIMMER/MOWER.
AVOID WEARING LOOSE CLOTHING OR JEWELRY, WHICH CAN CATCH ON THE MOWER’S MOVING
PARTS.
WE RECOMMEND WEARING GLOVES WHILE MOWING. BE SURE YOUR GLOVES FIT PROPERLY AND
DO NOT HAVE LOOSE CUFFS OR DRAWSTRINGS.
WEAR SHOES WITH NON-SLIP TREADS WHEN USING YOUR DR TRIMMER/MOWER. 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 TRIMMER/MOWER.

NEVER ALLOW PEOPLE WHO ARE UNFAMILIAR WITH THESE INSTRUCTIONS TO USE THE DR
TRIMMER/MOWER. ALLOW ONLY RESPONSIBLE INDIVIDUALS WHO ARE FAMILIAR WITH THESE
RULES OF SAFE OPERATION TO USE YOUR MACHINE.
NEVER PLACE YOUR HANDS, FEET, OR ANY PART OF YOUR BODY ON OR UNDER THE MOWER DECK
IN THE PATH OF THE SPINNING CORDS, BELT, PULLEYS, OR NEAR THE DISCHARGE OPENING WHILE
THE ENGINE IS RUNNING. KEEP AREA OF DISCHARGE CLEAR OF PEOPLE, ANIMALS, BUILDINGS,
GLASS, OR ANYTHING ELSE THAT WILL OBSTRUCT CLEAR DISCHARGE, CAUSE INJURY, OR DAMAGE.
KEEP BYSTANDERS AT LEAST 50 FEET AWAY FROM YOUR WORK AREA AT ALL TIMES. THE TIPS OF
THE CUTTING CORDS ON THE DR TRIMMER/MOWER CAN THROW STICKS, SMALL STONES, GRAVEL,
AND BITS OF DEBRIS OVER LONG DISTANCES AT GREAT VELOCITY. 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. RELEASE THE BAIL BAR

CALL TOLL FREE 1-800-DR-OWNER 5
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 MOWING ACTIVITY.
ASSUME THAT CHILDREN WILL REMAIN WHERE YOU LAST SAW THEM. ALWAYS FOLLOW THESE
PRECAUTIONS:
NEVER
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 TRIMMER/MOWER.
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 MOWER AWAY
FROM THE AREA OF THE SPILL AND
VAPORS HAVE DISSIPATED. WIPE UP ANY SPILLED FUEL TO PREVENT A FIRE HAZARD AND PROPERLY
DISPOSE OF THE WASTE.
AVOID CREATING ANY SOURCE OF IGNITION UNTIL THE GAS
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. STOP THE ENGINE, WAIT
FIVE (5) MINUTES TO MAKE CERTAIN 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.

CALL TOLL FREE 1-800-DR-OWNER 11
Adding the Engine Oil and Gasoline
YOU MUST ADD OIL BEFORE STARTING THE ENGINE. THIS MACHINE 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.
TO GET AN ACCURATE READING WHEN CHECKING THE OIL LEVEL:
THE MACHINE SHOULD BE ON A LEVEL SURFACE.
THE DIPSTICK SHOULD BE SCREWED DOWN ON BRIGGS & STRATTON ENGINES.
THE DIPSTICK SHOULD NOT BE SCREWED DOWN ON KAWASAKI ENGINES.
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: You will need approximately 15 to 22 ounces of SAE 30 high detergent oil depending on engine type. Use
only 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 information on oil quantity, and cold temperature oil specifications.
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 13).
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 13).
FILL GAS TANK OUTDOORS OR IN A WELL-VENTILATED AREA, AWAY FROM SPARKS, OPEN FLAMES, PILOT
LIGHTS, HEAT, AND OTHER IGNITION SOURCES.
NOTE: Discard the blue protective-shipping cap provided by some engine manufacturers. You will find this
protective-shipping cap under the Gas Fill screw cap or in the tank Filler Tube. See your Engine
Owner’s Manual for more fuel and oil information.
3. Fill the gas tank with fresh, unleaded gas (with a minimum of 85 Octane), to approximately 1/4"
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.
4. Open the fuel shut-off valve (on top of the Kawasaki gas tank only).
NOTE: To refill the gas tank, turn the engine OFF, and let the engine cool at least two (2) minutes before
removing the gas fill cap.

Adjusting the Handlebar
A
s
A
It is important to find a Handlebar height that allows the Mow-Ball Support to glide along the ground and
remain balanced so you do not have 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
Support as shown in Figure 15 on page 25. You may find you like different
Handlebar heights for different mowing conditions.
There are two ways to adjust the height of the Handlebar outlined in the following steps:
1. Loosen both the Adjustment Knobs and move the Handlebar up or down until the adjustment is
the same on both sides. Use the Notches on the Adjusters (Figure 4a) to measure how many Teeth
you have moved away from the center. When you have 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 (Figure 4b). 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 4a). You
may need to adjust the PTA

Lever as well. See the next section.

The DR TRIMMER/MOWER Cutting Cords
BEFORE PERFORMING ANY ADJUSTMENT, MAINTENANCE PROCEDURE OR INSPECTION, STOP THE
ENGINE, WAIT FIVE (5) MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE,
KEEPING IT AWAY FROM THE SPARK PLUG.
RUNNING THE TRIMMER WITH ONLY ONE CORD INSTALLED, OR CORDS INSTALLED AT OTHER THAN
180 DEGREES APART CAN CAUSE EXCESSIVE VIBRATION AND MAY DAMAGE THE MACHINE.
The following figures (Figures 9 and 10) illustrate the Cords installation on the line plates. These figures
show the Line Plates from a cross section point of view. It may look complicated, but once you have done it
a couple of times, it’s easy. There are two (2) sets of installation points on each Line Plate. Each pair is 180
degrees apart. One (1) set of holes is for larger Cord (Blue, 175 mil, and Green, 155 mil) and is marked with
large arrows. The other set of holes is marked with small arrows and are at 90 degrees to the larger holes
and they accommodate the smaller Cord (Orange, 130 mil). Always install two (2) Cords one opposite the
other.

Installing Cords
The Cord installation method is shown in Figures 11–13. Your DR TRIMMER/MOWER shipped from the
factory with the Cords installed in this manner.
WHEN USING PTA, INSTALL THE CUTTING CORDS IN ONE OF THE BOTTOM FOUR LINE PLATES.
INSTALLING THE CUTTING CORDS ON THE UPPER LINE PLATES CAN CAUSE THE CORD TO HIT THE
WHEEL. FOR MORE INFORMATION ON USING PTA
NOTE: After you install the Cords, and before
trimming, engage the Cutting Head with
the engine running and spin new Cords for
a few seconds so they pull tight and are set.
1. Insert the ends of the Cords into the
openings in the Line Plate, as shown in
Figure 11. There are different sized arrows at
the insertion points to indicate what size
Cords fit the holes.
, SEE USING PTA ON PAGE 20.
2. Push the Cord through until it comes out the
center hole in the Line Plate as shown in
Figure 12. You may also reference Figures 9
and 10 for installing the Cords. 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, (Figure 13), and then pull the Cords
tight.

Cord Tips
We ship three (3) thicknesses of Cutting Cord with your DR TRIMMER/MOWER.
The Cords are Blue (175-mil), Green (155-mil) and Orange (130-mil). Because conditions and vegetation
vary so much, you should experiment with Cord weights (diameters) 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.
Cord life depends on trimming conditions. Replace Cords when they become broken or frayed.
The smallest diameter Cord capable of cutting the material at hand combined with the fastest engine
speed usually provides the best grass trimming performance. When you need more power for thicker
growth such as berry canes, brambles, thistles, or ragweed, you may want to use the 155-mil or 175-mil
Cord in combination with the highest engine speed.
Ease the ends of the Cord into heavy growth and move slowly through thick growth. If there are woody
weeds in the material you are cutting, the cutting Cords may wrap around the stalks they cannot cut,
and pull away from the trimmer head.
Please note that installing more than two (2) 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 (2) 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
that you are replacing.
If the Cord breaks off flush at the Line Plate, use the new Cord to push out the old Cord.
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.
24 DR® TRIMMER/MOWER
Adjusting the Cutting Height
WHEN USING THE PTA FEATURE, INSTALL THE CUTTING CORDS IN ONE OF THE FOUR BOTTOM LINE
PLATES ONLY.
Adjusting the cutting height is easy. Cutting heights range in 1/2-inch increments from 1-1/2 inches when
using the bottom Line Plate, to approximately 4 inches when using the top Line Plate (Figure 14).
Install the Cutting Cords in the Line Plate that gives you the desired cutting height.
Figure 14
The 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. To achieve the best and
smoothest cut, do not lift up on the Handlebar while operating your DR TRIMMER/ MOWER. Lifting
the Handlebar will force weight down on the Mow-Ball
cutting, and produces an unsatisfactory cut. Ideally, the Mow-Ball
Support. This uses more energy, slows the
Support should lightly rest on the
ground while the wheels balance most of the weight of the machine (Figure 15).

Obstacle Tips
Dealing with obstacles in the terrain is easy with your new DR TRIMMER/MOWER. The following section
explains how to approach most common obstacles.
THE TRIMMER ENGINE'S POWER CAN EASILY THROW STONES, STICKS, AND OTHER DEBRIS AT GREAT
VELOCITY, WHICH COULD CAUSE PERSONAL INJURY OR PROPERTY DAMAGE. DO NOT RUN THE
MACHINE OVER GRAVEL DRIVEWAYS OR OVER LOOSE STONES OR MULCH WITH THE TRIMMER HEAD
SPINNING.
Tip: 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.
Always check your work area before trimming and remove any debris that might tangle or damage the
machine.
If you do run into debris and the trimmer becomes tangled, turn off the engine and disconnect the
spark plug wire before attempting to untangle the machine.
For the neatest appearance, do your trimming first, discharging clippings away from borders and
shrubs, then do your mowing.
Many owners like to mow easy, open areas with their regular riding or walk-behind mower and finish
trimming all the odd and hard-to-reach spots with the DR TRIMMER/MOWER (Figure 16).
26 DR® TRIMMER/MOWER
Figure 16
Heavy Growth
Take your time in heavy growth.
Be sure to keep uncut material to your
left, maintaining a clear discharge area to
your right (Figure 17).
If the machine cannot do it all in one
pass, overlap half of the cutting swath.
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
ground.
Ease the DR TRIMMER/MOWER into
denser growth. If the material is too
tough or woody to cut, the Cutting Cords
will wrap around it, wear down, or even
break off.
Support close to the
Sometimes the growth is so heavy, you
cannot mow it in rows. Use a forward
and back “vacuum cleaner” motion in
these cases.
Tips:
Use the “two pass”, one half overlap
method, whenever possible.
SELF-PROPELLED Model Tips:
In heavy growth it is best to make two (2)
passes at 1/2 the cutting width.
If you must go back and forth in the
“vacuum cleaner” motion, be sure to
release the Wheel Clutch Lever when
pulling the Trimmer back.
Figure 17
CALL TOLL FREE 1-800-DR-OWNER 27
MAKE SURE OF YOUR FOOTING WHEN OPERATING IN WET CONDITIONS.
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. You can use the DR 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 18).
NOTE: NEVER mow in the rain. Water on the
spark plug may cause the engine to stall.
Very Dry Conditions
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.
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 recoil-starter housing and engine cooling fins. Please
see the Engine Owner’s Manual for more detailed information on cleaning the air intake, air filter, and
cooling system on the engine.
Figure 18
Slopes
MAKE SURE OF YOUR FOOTING WHEN OPERATING ON 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 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 side, so you can use it like
a lawn broom to make windrows for easy clean-up.
Firebreaks
Use your Trimmer as a labor saving tool to cut material when creating firebreaks.
Garden Clean-Up
The DR TRIMMER/MOWER 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.

Battery Care (Electric-Start Models)
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 Trimmer 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 charging for as long as 48 hours.
At 2 amps, the battery may need charging for as long as 24 hours.
NOTE: Using the recoil starter and then running the engine will not recharge a dead or significantly discharged
battery.
To connect a battery charger to your DR TRIMMER/MOWER, follow the steps listed below.
1. Detach the two battery wires going to the battery on your DR TRIMMER/ MOWER.
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
LEAVE THE BATTERY CHARGER WIRES CONNECTED TO THE BATTERY, THE BATTERY WILL DISCHARGE
ITSELF BACK INTO THE CHARGER.

NEVER STORE THE DR TRIMMER/MOWER 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 TRIMMER/MOWER SHOULD BE STORED OUT OF THE REACH OF
CHILDREN AND IN A DRY LOCATION.
NOTE: Please refer to the Engine Owner's Manual for engine-specific procedures.
Check the Drive Belt(s) for wear.
Change the engine oil (and Oil Filter, if applicable). This will help to eliminate sludge and acids in
the engine.
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 engine air filters.
Clean any dirt and debris from the cylinder head cooling fins, carburetor linkage, blower housing,
debris screen, and muffler area of the engine.
Remove any wrapped weeds from the Mow-Ball™ Support, wheel spokes, and axles. Using a stiff
brush, clean grass and debris from the top and underneath the Trimmer Deck.
Remove the Bottom Shield and clean out any debris. See page 33 or 34.
Check to make sure the operator controls are moving freely. Lubricate the Throttle Lever, PTA
Lever (SPRINT
lubricant if necessary.
, PRO and COMMERCIAL models), and Key Switch with FLUID FILM or similar
If your engine has a fuel filter, replace it.
If your DR TRIMMER/MOWER 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 (on top of the Kawasaki gas tank
only) to prevent carburetor overflow and leakage.
On Electric-Starting models, remove the battery or store your DR TRIMMER/MOWER 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.

Daily Checklist for the DR TRIMMER/MOWER
To help maintain your DR TRIMMER/MOWER 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 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.
[ ] CUTTING CORDS: Replace broken or frayed Cords.
[ ] MOW-BALL™ SUPPORT and LINE PLATES: Check the Mow-Ball™ Support and Line Plates for
wear and replace as needed.
[ ] GENERAL CONDITION: Check the general condition of the machine, e.g.; nuts, bolts, welds etc.
