CHILDREN
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and
mowing activity. They do not understand the dangers. Never assume that children will remain where you last saw them.
◼Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator.
◼Be alert and turn the mower off if a child enters the area.
◼Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects that may obscure your vision of a
child who may run into the mower.
◼Never allow children under 15 years old to operate a power mower. Children 15 years old and over should read and understand
the operation instructions and safety rules in this manual and should be trained and supervised by a parent. Only responsible
individuals who are familiar with these rules of safe operation should be allowed to use this machine.

designed to perform only one job: to mow grass.
◼Don’t overreach – Keep proper footing and balance at all times.
◼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.
◼Keep the area of operation clear of all persons, particularly small children, and pets.
◼Before and while moving backwards with the mower, look behind and down for small children and other people.
◼Keep clear of the discharge opening at all times.
◼This machine is a precise piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times. Your unit
has been designed to perform one job: to mow grass. Do not use it for any other purpose.
◼Don’t force the lawn mower – it will do the job better and more safely at the rate for which it was designed.
◼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 blade contact or an injury from thrown objects, stay in the operator zone behind the handles and 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.
◼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

8
dusty.
◼Dress properly –Do not wear loose clothing or jewelry. They can be caught in moving parts. Use of rubber gloves and footwear
is recommended when working outdoors. Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts. Shirts and
pants that cover the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet, sandals,
slippery or lightweight (e.g., canvas) shoes.
◼Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can amputate hands and feet.
◼A missing or damaged discharge cover can cause blade contact or injuries from thrown objects.
◼Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. Do not hold
onto the mower if you are falling; immediately release the handle.
◼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 mower to fully extend your arms.
◼Be sure you are well balanced with sure footing.
◼Pull the mower back slowly, no more than half way toward you.
◼Repeat these steps as needed.
◼Do not operate the mower while under the influence of alcohol or drugs.
◼Stay alert –watch what you are doing. Use common sense. Do not operate the lawn mower when you are tired.
◼The motor/blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device
inoperative and may result in personal injury through contact with the rotating blade. The motor/blade control handle must
operate easily in both directions and automatically return to the disengaged position when released.
◼Avoid dangerous environments –Don’t use lawn mowers in damp or wet locations so as to avoid slipping and falling during
operation.
◼Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your footing, release
the motor/blade control handle immediately and the blade will stop rotating within three seconds.
◼Stop the blade when crossing gravel drives, walks or roads.
◼If the equipment should start to vibrate abnormally, immediately stop the motor, remove the battery and check for the cause.
Vibration is generally a warning of trouble.
◼Before cleaning the machine, unclogging the chute or removing or replacing the grass bag, mulching insert, or side discharge
chute, turn the motor off and wait until the blade comes to a complete stop, then remove the battery pack. The cutting blade
continues to rotate for a few seconds after the motor is shut off. Never place any part of the body in the blade area until you
are sure the blade has stopped rotating.
◼Never operate the mower without the proper trailing shield, discharge cover, grass bag, mulching insert, side discharge chute,
motor/blade control handle or other safety protective devices in place and working. Never operate the mower with damaged
safety devices. Failure to do so can result in personal injury.
