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.
Dress Appropriately
·We recommend using safety glasses. Use a face or dust mask if operating in dusty conditions.
·Always wear substantial footwear and long pants. Do not wear loose clothing or jewelry. They
can get caught in the moving parts.
Preparation
·Be thoroughly familiar with the controls and proper use of the DR®WHISPER LITE® before
operating it.
·Never operate the DR®WHISPER LITE®without the proper guards, safety switches or other
safety and 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.
·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. Objects struck by the lawn mower blade can cause severe injuries. Also note the
location of holes, stumps and other possible hazards.
·Mow only in daylight or in good artificial light.
Operation
·The length of time that a battery pack 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 pack
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

DR®WHISPER LITE®CORDLESS Electric Mower Safety & Operating Instructions iii
in thick grass. DR®WHISPER LITE®CORDLESS Electric Mower will do a better and safer job
when cutting at a steady rate.
·Your mower can operate as a mulcher or bagger. Learn how to use the proper cutting blade, and
how to use the grass catcher or discharge chute block for the right application.
·Do not insert the SAFETY KEY into the mower until you are ready to operate the mower. Store
the safety key away from children and people not authorized to use the mower.
·The cutting blade turns when the motor is running (there is no clutch to allow the blade to stop
while the motor is running). Learn how to quickly stop the mower's motor and note that the
blade will continue to rotate for up to three seconds after the motor has stopped.
·Stop the blade and remove the safety key whenever you leave the operating position (behind the
handlebar) for any reason, including clearing grass and making any inspections, adjustments or
repairs to the mower.
·Do not put your hands and feet near or under rotating parts or when the safety key is still inserted.
Keep clear of the discharge area while the motor is running.
·Before cleaning, repairing, inspecting, adjusting the height of the cut, or exchanging the
discharge chute block and grass catcher, be sure the motor is off, remove the safety key and make
certain the blade has stopped rotating.
·Do not operate the mower in the rain or when the grass is wet.
·Never cut grass by pulling the mower towards you. It is designed to be pushed forward while
cutting only.
·USE EXTREME CAUTION when maneuvering backwards. Always look first to check your
footing and release the operator presence bar before moving backwards.
·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.
·Stop the motor when crossing over loose materials such as gravel drives, walks or roads. Objects
discharged by the mower can be hazardous.
·After striking a foreign object or if the mower vibrates abnormally, stop the motor and remove
the safety key. 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.
·Remove the safety key when the mower is not in use.
·Allow the motor to cool for at least 5 minutes before storing the mower in any type of tight space
or enclosure.
·Do not use the DR®WHISPER LITE®for any job other than those for which it is intended.

Maintenance and Storage
!WARNING: ALWAYS remove the safety key before performing any adjustments or repairs.
·Maintain the lawn mower with care—keep cutting edges sharp and clean for the best and safest
performance. Keep all nuts, bolts and screws tight to be sure the mower is in safe operating
condition. Follow the instructions in this manual for changing accessories.
·Periodically inspect the exposed cords on the charger unit and the handlebar for damage. If
damage occurs, do not use the mower until the cords have been replaced or repaired.
·Do not operate the mower if it does not start normally or does not stop normally when the
operator presence bar is released.
·Use identical replacement blades only. Check the blade and motor mounting bolts at frequent
intervals for proper tightness.
·Keep mower clean and dry. Use a damp cloth when cleaning. Never use water, gasoline,
solvents or other petroleum-based or solvent-based products for cleaning.
·When not in use, store the lawn mower indoors in a dry place and out of the reach of children.
·To reduce fire hazard, keep mower free of grass, leaves or excessive grease.
Battery Safety
·Do not charge the lawn mower battery pack in the rain or in wet locations.
·Exercise care in handling the battery pack in order not to short circuit it with conducting
materials such as rings, bracelets and keys. When short circuited, 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.
·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 Disposal
Please dispose of used batteries responsibly, according to your local hazardous
materials regulations.
