Important Safety Instructions
!
WARNING: We want you to enjoy years of safe and productive use from your DR® WHISPER
LITE® CORDLESS Electric Mower. We don’t want you to get injured, so please take a few
moments to read the following guidelines for safely operating your new machine.
READ THESE INSTRUCTIONS
Protect those around you
· Do not allow children, other bystanders or pets in your work area when the mower is being
operated.
· Only adults and teenagers with a thorough understanding of these instructions should operate the
mower.
Preparation
· Use safety glasses. Always use a face or dust mask if operating in dusty conditions.
· Dress appropriately. Always wear substantial footwear and long pants. Do not wear loose
clothing or jewelry. They can get caught in the moving parts.
· Be thoroughly familiar with the controls and proper use of the DR® WHISPER LITE®.
· Do not operate the mower without the proper side chute or mulch cover in place. Use of
accessories not recommended in the manual may increase the risk of injury.
· Never operate the DR® WHISPER LITE® mower without the proper guards, safety switches or
other safety protective devices in place and properly connected. Inspect to determine that these
safety devices are properly installed, in good repair, and operate properly. If the condition or
operation of these devices is questionable, they must be repaired or replaced before using the
mower.
· Objects struck by the lawn mower blade can cause severe injuries. Thoroughly inspect the area
where the mower is to be used and remove all stones, sticks, wire, dog bones, pet supplies or
lawn toys, and other foreign objects which could be thrown by the mower blade. Also note the
location of holes, stumps and other possible hazards.
· Mow only in daylight or in good artificial light.
· Never operate the mower in wet grass or in the rain. Wet conditions can be slippery.
Operation
· The length of time that a battery can hold its charge while mowing a lawn depends upon lawn
conditions; tall, thick, or wet grass make the mower work harder and the battery discharge faster.
· Before starting the mower, adjust the cutting height to cut 1" to 2" of grass at a time. Cut thicker
grass at a greater cutting height, or cut a narrower swath. Do not force the lawn mower forward
in thick grass. The DR® WHISPER LITE® will do a better and safer job when cutting at a steady
rate.
· Stop the blade whenever you leave the operating position (behind the handlebar) for any reason,
including clearing grass and making any adjustments, repairs or inspections to the mower.
· Before cleaning, repairing, inspecting, adjusting the height of the cut, or exchanging the
mulching cover and side discharge chute, remove the battery pack and make certain the blade has
stopped.
· Look behind you before pulling the mower backwards to avoid falling.
DR® WHISPER LITE® CORDLESS Electric Mower Safety & Operating Instructions
i
(Operation, continued)
· Mow across slopes, never up and down. Exercise caution when changing directions on slopes.
Do not mow steep slopes or other areas where stability or traction is in doubt.
· Do not put your hands and feet near or under rotating parts. Keep clear of the discharge area
while the motor is running.
· Stop the blade when crossing over loose materials such as gravel drives, walks or roads. Objects
discharged by the mower can be hazardous.
· Do not use the DR® WHISPER LITE® for any job other than those for which it is intended.
· Do not overreach—keep proper footing and balance at all times.
· After striking a foreign object or if mower vibrates abnormally, stop the blade and remove the
battery pack. Inspect the mower for any damage and repair the damage before restarting and
operating the lawn mower. Vibration is generally a sign of trouble.
· Stay alert and watch what you are doing. Do not operate the lawn mower when you are tired or
under the influence of drugs or alcohol.
Maintenance and Storage
· Maintain the lawn mower with care—keep cutting edges sharp and clean for the best and safest
performance. Be sure the mower is in safe operating condition. Keep all nuts, bolts and screws
tight. Follow the instructions in this manual for changing accessories.
· When not in use, store the lawn mower indoors in a dry place and out of the reach of children.
· Keep mower handlebars dry and free from oil and grease.
· To reduce fire hazard, keep mower free of grass, leaves or excessive grease.
· Use identical replacement blades only. Check the blade and motor mounting bolts at frequent
intervals for proper tightness.
· Have your mower inspected and serviced each year by an authorized Briggs & Stratton service
center. Please call Country Home Products® and we will pre-arrange a visit to an authorized
service center. Not all Briggs and Stratton service centers are knowledgeable about this mower.
You can also send the mower to the Service Department at Country Home Products® for the
above mentioned service.
· Factory specified Briggs & Stratton replacement parts should be used to assure adequate
protection against injury (available from COUNTRY HOME PRODUCTS
®
).
Battery Safety
· Use only part #CEP1003 replacement battery pack (available from Country Home Products ®).
· Do not charge the lawn mower battery in the rain or in wet locations.
· Exercise care in handling the batteries in order not to short the battery with conducting materials
such as rings, bracelets and keys. The battery or conductor may overheat and cause burns.
· Do not attempt to replace individual batteries inside the battery pack. Mixing fresh and
discharged batteries could increase internal cell pressure and rupture the discharged battery.
Improper wiring within the battery pack could result in leakage or explosion.
· Batteries that can no longer accept a charge should be returned to an authorized Briggs &
Stratton service center or a local recycling center. Do not dispose of batteries in a fire: the
battery cells may explode. Do not open or mutilate the batteries. Released electrolyte (battery
acid) is corrosive and will cause damage to eyes, skin or clothes. Battery acid is toxic if
swallowed or if the fumes are inhaled.

Battery Charging Instructions
!
WARNING: The battery contains corrosive fluid and toxic mater ial. Handle with care. Keep
away from children. Do not puncture, disassemble, m utilate or incinerate. Explosive gases
could be vented during charging or discharg ing. Use in a well ventilated area, away from
sources of ignition.
Charge the battery pack(s) indoors or in a dry area
out of the weather. Use only the battery charger
provided with the mower (Briggs & Stratton part
number 497400). First plug the battery charger lead
into the battery (Figure 10), then plug the charger
into any standard 110/120 volt household electrical
outlet. If you have a dual or "Y" lead, you can use
the other lead to charge another battery pack at the
same time, though charging will take longer (Figure
11).
If an extension cord is required, use one rated for
outdoor use that is at least wire size 16 AWG.
Connect the extension cord to the charger before
plugging the extension cord into the electrical
outlet. Make sure to recharge the battery packs
fully when your finished using the mower. It takes
at least 16 hours to recharge a completely
discharged battery, and at least 24 hours to recharge
two battery packs at once. The red light on the
battery charger indicates that the battery charger is
plugged into an electrical outlet; the green light
indicates that the battery is fully charged.
Figure 10
The battery should be charged every 30 to 60 days
if the mower is not used. Charge the battery for a
maximum of 48 hours only.
Important: Always disconnect the battery charger
(or the extension cord, if used) from both the electrical outlet and the battery pack, or the battery
may discharge itself back into the charger. Be sure that the battery is disconnected from BOTH of
these!
Figure 11
✦ Reminder: The length of t im e t hat a battery can hold its charge while mowing a lawn depends
upon lawn conditions; tall, thick, or wet grass make the mower work harder and the battery
discharge faster.

Electronic Cut-Out Switches
Circuit Breaker
A circuit breaker is located to the left of the power
key on top of the mower. This breaker may trip
when cutting heavy or thick grass, or when a wire
short-circuits. You know the circuit breaker has
tripped if the mower will not run and the white
circuit breaker reset button is projecting up into the
transparent rubber boot. If this happens, reset the
breaker by depressing the reset button (Figure 12).
If the circuit breaker does not reset or if it trips
repeatedly under normal cutting conditions, call one
of our Customer Service Representatives TOLL-
Figure 12
FREE 1(800) DR-OWNER(376-9637).
Note: If the circuit br eaker trips during the operation of the mower, allow the electric motor to cool
for at least one minute bef or e r esetting the breaker.
Low-Voltage Cut-Out Switch
The motor is equipped with an electronic cut-out switch. This device stops the mower if the battery
charge becomes excessively low and the blade speed becomes slow after an extended period of
mowing. Before restarting the mower, replace the battery pack with a fully charged battery pack (the
discharged battery pack should be recharged immediately to avoid damage).
Circuit breaker
Power key
Cutting Height Adjustment

Lawn Care Tips
· Mow your lawn as often as necessary.
· Never remove more than one third of the leaf blade during any one mowing session. When more
than one third of the blade is removed, the grass plant produces less food for itself and therefore
becomes weaker and more susceptible to disease and insect damage.
· Grass that is allowed to get taller will have a stronger, larger root system that will better
withstand dry periods.
· Depending on the health of your lawn and the weather, it may be necessary to mow your lawn
twice a week during the fast growing periods to avoid taking off more than one third of the leaf
blade.
· Your lawn will benefit more if you leave the clippings right where they are. When left in place,
grass clippings shade the soil surface and reduce moisture loss. Grass clippings also add organic
matter to help improve the soil by returning valuable nutrients to the soil such as nitrogen,
phosphorous, and potassium when they decompose.
· The only time it is absolutely necessary to remove grass clippings is when they accumulate in a
thick layer that smothers the lawn and doesn't decompose quickly.
· Keep your mower blade sharp! A sharp mower blade cuts the grass quickly and cleanly, using
less of the mower's power, which conserves battery life. For best results, inspect the blade often
and have an extra, sharp blade ready to as a replacement while the dull blade is being sharpened.
· Alternate the mowing pattern on your lawn frequently. By changing the pattern and direction of
the cut, you'll improve the health and appearance of your lawn. Following the same mowing
pattern causes soil compaction and turf wear from the mower wheels.

Maintenance
!
WARNING: Be certain to remove the power key and the battery pack before performing any
adjustment or repair.
Service Assistance & Replacement Parts
To maintain the original quality of your mower, use genuine Briggs & Stratton replacement parts
only. To obtain the correct part for your particular mower, always specify the model number (found
on the name plate). Contact one of our Customer Service Representatives Toll-Free 1(800)DR-
OWNER (376-9637) for parts and service assistance. We recommend taking your mower to a
Briggs & Stratton authorized service center once each year for inspection and addition of any new
devices which might upgrade the safety of your mower. Please call Country Home Products® and we
will pre-arrange a visit to an authorized service center. Not all Briggs and Stratton service centers are
knowledgeable about this mower. You can also send the mower to the Service Department at
Country Home Products® for service.
Cleaning
1. Remove the power key.
2. Wipe the mower clean with a dry cloth.
Periodically remove the battery pack and wipe
the battery cavity clean (do not use water).
3. To prolong the life and efficiency of your
mower, clean the underside of the mower deck
after each use. Tilt the mower forward or on
its side and scrape the underside clean (make
certain the power key and the battery have been
removed).

REPLACE the blade if it's badly chipped, bent, out
of balance, or as soon as a notch starts wearing in
the tip between the flat surface and upturned lift
(Figure 16, view B). This type of wear pattern
occurs more rapidly in sandy soil conditions.

WARNING: Be certain to remove the power key and the battery pack before performing any
adjustment or repair.
To Sharpen the Blade
When the blade is dull, cut ends of the grass
will be ragged and usually turn brown soon
after mowing. If the blade is in otherwise good
condition, sharpen it when the cutting edges
become dull.
!
Caution: To avoid cutting yourself on the
blade, wear heavy leather gloves.
For best results, remove the blade (Figure 17)
and sharpen the cutting surfaces at an angle of
Loosen the blade mounting bolt

25 degrees.
Check the blade after sharpening to make sure
Figure 17
it is still balanced (see "To Balance the Blade"
below). It will cause excessive vibration if
unbalanced.
Blade adapter
Before reassembling the blade and the blade
adapter to the unit, brush any built up debris
out of the grooves of the motor base (Figure
18). Coat the motor crankshaft and the inner
surface of the blade adapter with light oil (or
engine oil).
Install the sharpened or replacement blade with
components in same sequence as removed. Do
Clean grooves in the motor base
not substitute any components here. Tighten
the blade retaining cap screw.
Important: When replacing the blade, be sure to inst all it with the st iffening ribs on the blade
facing toward the mower.
Figure 18
To Balance the Blade
Because you are removing metal from each side of the blade, make sure to remove an equal amount
from each side to keep the blade balanced. A badly imbalanced blade will cause your machine to
vibrate excessively. The best way to balance a blade is with a blade balancer (usually about $3.00 at
your local hardware store) or with a large nail or bolt. After sharpening the blade, place it on the
balancer and check the level. If one side of the blade tips lower, you need to sharpen that side more
to balance the blade.
