WARNING Read and
understand all instructions before using
this product. Failure to follow all
instructions listed below may result in
electric shock, fire, and/or serious
personal injury. When using an electrical
appliance, basic precautions should
always be followed, including the
following:
CHILDREN AND BYSTANDERS
Tragic accidents can occur if the operator
is not alert to the presence of children or
bystanders.
• Keep the area of operation clear of all
persons, particularly small children, and
pets.
• Use extreme care when approaching
blind corners, doorways, shrubs, trees, or
other objects that may obscure your vision
of a child or bystander. Keep children,
bystanders, helpers and pets at least 100
feet (30m) from the mower while it is in
operation.
• Stop the machine if anyone enters the
area.
• Never allow children under 14 years old
to operate a power mower. Operators 14
years old and over should fully read and
understand the operator’s manual and
safety rules. Only responsible individuals
who are familiar with these rules of safe
operation should be allowed to use this
machine.
GENERAL OPERATION
• Read this operator’s manual carefully in
its entirety before assembling or operating
this machine. Read, understand, and
follow all instructions on the machine and
in the manuals before operation.
• Familiarize yourself with the controls
and proper use of this machine before
operation. Save this manual for future and
regular reference.
• Do not use the lawn mower for any job
except that or which it is intended. Your
lawn mower has been designed to perform
only one job: cut grass.
• Never attempt to make a wheel height
adjustment while the motor is running.
• Don’t force the lawn mower, it will do the
job better and more safely at the rate for
which it was designed.
• Don’t overreach, keep proper footing and
balance at all times. Many injuries occur
as a result of the mower being pulled over
the foot during a fall caused by slipping or
tripping. A slip and fall can cause serious
personal injury. If you feel you are losing
your footing, release the control handle
immediately and the blade will stop rotating
within three seconds.
• Thoroughly inspect the area where the
equipment is to be used and remove all
stones, sticks, wires, bones, and other
foreign objects.
• Prevent unintentional starting. Ensure
the bail lever is released and the mower
had stopped before swapping the battery
pack, picking up or carrying the machine.
• Never pull the mower back toward you
while you are walking. If you must back
the mower away from a wall or obstruction,
first look down and behind you to avoid
tripping, and then follow these steps:
• Step back from the mower in order to fully
extend your arms.
• Be sure that you are well balanced.
• Pull the mower back slowly.
• Disconnect the battery pack from the
appliance before making any adjustments,
changing accessories, or storing appliance.
Such preventive safety measures reduce the
risk of starting the appliance accidentally.
• Before and while moving backwards with
the mower, look behind and down for small
children and other people.
• Do not operate the mower while under the
influence of alcohol or drugs. Stay alert
and watch what you are doing at all times.
Use common sense and do not operate

Page 5
the lawn mower when you are tired.
• Always wear safety glasses or safety
goggles during operation and while
performing an adjustment or repair to
protect your eyes. Thrown objects that
ricochet can cause serious injury to the
eyes.
• Always use a face or dust mask if the
operation is dusty.
• Keep clear of the discharge opening at
all times. Do not put hands or feet near
rotating parts or under the cutting deck.
Contact with the blade can amputate
hands and feet.
• Plan your mowing pattern to avoid
discharge of material toward roads,
sidewalks, bystanders and the like. Also,
avoid discharging material against walls or
obstructions, which may cause discharged
material to ricochet back toward the
operator.
• To help avoid the blade or an injury from a
thrown objects, stay in the operator zone
behind the handles.
• A missing or damaged discharge cover
can cause blade contact or injuries from
thrown objects.
• Objects struck by the lawn mower blade
can cause severe injuries to persons. The
lawn should always be carefully examined
and cleared of all objects prior to each
mowing.
• Stop the blade when crossing gravel
drives, walks or roads.
• Follow all charging instructions and do
not charge the battery pack or appliance
