SAFETY INSTRUCTIONS
WARNING!
To reduce the risk of injury, the user must read and understand the operator’s manual
before using this product.
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions listed
below and on the machine could result in electric shock, re, serious personal injury
and/or death.
READ ALL INSTRUCTIONS
• This cutting machine is capable of amputating hands and feet and throwing objects. Failure to
observe all safety instructions could result in serious injury or death.
• Avoid dangerous environment — Do not use the lawn mower in damp or wet conditions or
operate in the rain.
• Keep children away — Keep all bystanders, children, and pets at least 100 ft. away. Stop the
mower and turn off the machine if anyone enters the area.
• Tragic accidents can occur if the operator is not alert to the presence of children. Children
are often attracted to the machine and the mowing activity. NEVER assume that children will
remain where you last saw them.
• Keep children out of the mowing area and in the watchful care of a responsible adult other
than the operator.
• Be alert; stop and turn machine off if a child enters the area.
• Before and while backing, look behind and down for small children, bystanders, and pets.
• Be especially careful before and when backing with the bagger kit installed, as it may limit
visibility. Always look closely behind and down for small children, bystanders, and pets, and
move the mower slowly.
• Never carry children, even with the blades shut off. They may fall off and be seriously injured
or interfere with safe machine operation. Children who have been given rides in the past may
suddenly appear in the mowing area for another ride and be run over or backed over by the
machine.
• Never allow children to operate the machine.
WARNING!
CHILDREN CAN BE KILLED OR SERIOUSLY INJURED BY THIS EQUIPMENT. The
American Academy of Pediatrics recommends that children be a minimum of 16
years of age before operating a riding lawn mower.
• Use extreme care when approaching blind corners, shrubs, trees, or other objects that may
block your view of a child.
• Dress properly — Do not wear loose clothing or jewelry. They can be caught in moving
parts. The use of rubber gloves and substantial, fully enclosed footwear with good traction is
recommended when using this mower.
• Never leave a running machine unattended. Always turn off blades, set parking pedal, stop
motor, and remove key before dismounting.
• Check brake operation before each use and frequently during use. Adjust and service as
required.
• Keep hands and feet away from cutting area, which is located under the mower deck and
inside the side discharge chute. Keep clear of the side discharge chute opening at all times.
Do not reach under the mower deck.

4
• Operate the lawn mower only in daylight or good articial light.
• Use safety glasses — Always wear eye protection with side shields marked to comply with
ANSI Z87.1. Use face mask if operation is dusty.
• Use the right appliance — Do not use the lawn mower for any job except that for which it is
intended.
• Do not force the lawn mower — It will do the job better and safer at the rate for which it was
designed.
• Do not charge lawn mower in rain, or in wet locations.
• Stay alert — Watch what you are doing and use common sense when operating the lawn
mower. Do not operate the mower while tired, upset, or under the inuence of drugs, alcohol,
or medication. A moment of inattention while operating the lawn mower may result in serious
personal injury.
• Maintain lawn mower with care — Keep machine in good working condition. Keep blades
sharp and guards in place and in working order. To prevent serious personal injury, damage to
the mower, and for best performance, replace damaged or unevenly worn blades.
• Check all nuts, bolts, and screws before each use for proper tightness to be sure the
equipment is in safe working condition. Mower blades are sharp. Wrap the blades or wear
gloves, and use extra caution when servicing them.
• Stop the motor, wait until blades come to a complete stop, and remove the start key before
cleaning the lawn mower, removing the bagger, or removing the mulch cover.
• Replace blade if it is bent or cracked. An unbalanced blade causes vibration that could
damage the motor drive unit or cause personal injury. Sharpen a dull blade equally at each end
to maintain the balance. Clean the blade thoroughly and check its balance by supporting it
horizontally on a thin nail through its center hole. The nail should be in a horizontal position. If
either end of the blade rotates downward, remove some metal from the heavy lower end until
the blade is balanced. It is balanced when neither end drops.
• The side discharge chute is a spring-loaded guard that covers the side discharge opening
on the mower deck and deects grass clippings and debris away from the operator. Always
ensure that the motor is off and the blades have stopped moving before inspecting, moving,
cleaning, or performing maintenance on the side discharge chute.
• Always use safety protective devices. Do not operate the mower without the side discharge
chute in place and working properly. Mulch cover should be correctly installed and working
properly during mulching operation and bagger kit should be correctly installed and working
properly during bagging operation.
• Never interfere with the intended function of a safety device or reduce the protection provided
by a safety device. Check their proper operation regularly.
• Never tamper with safety devices. Check for proper operation regularly.
• Follow manufacturer’s instructions for proper operation and installation of accessories. Only
use accessories approved by the manufacturer. The use of other accessories may increase the
risk of injury.
• Clear the work area before each use. Remove all objects such as rocks, sticks, metal, wire,
bones, toys, fallen tree limbs, tree nuts, or other objects which can be thrown by the blade.
• Objects struck by the lawn mower blades can cause severe injuries to persons. The lawn
should always be carefully examined and cleared of all objects prior to each mowing. If the
lawn mower strikes a foreign object, follow these steps:
• Stop the lawn mower, set the parking pedal, wait until the blades come to a complete stop,
and then remove start key.
• Thoroughly inspect the mower for any damage.
SAFETY INSTRUCTIONS

5
• Replace the blade if it is damaged in any way. Repair any damage before restarting and
continuing to operate the mower.
• Slopes are a major factor related to loss of control and tip-over accidents, which can result in
severe injury or death. Operation on all slopes requires extra caution. If you cannot back up
the slope or if you feel uneasy on it, do not mow it. Never use on steep slopes greater 15°.
• Never attempt to ride on a steep slope or mow a slope that is greater than 15°. To determine
the angle of your slope, use the Slope Guide at the back of this manual.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn
the machine. Tall grass can hide obstacles.
• Use a slow speed so you will not have to stop suddenly or accidentally accelerate while on a
slope.
• Do not mow on wet grass. Tires may lose traction and you may lose control.
• Always keep the direction control switch in the forward position when going down slopes. Do
not shift to neutral and coast downhill, which may cause you to lose control of the mower.
• Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades
and proceed slowly straight down the slope.
• Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or
direction, which could cause the machine to roll over.
• Use extra care while operating machine with baggers or other attachments; they can affect the
stability of the machine. Do not use on steep slopes greater than 15°.
• Do not try to stabilize the machine by putting your foot on the ground.
• Do not mow near drop offs, ditches, or embankments. The machine could suddenly roll over
if a wheel goes over the edge or if the edge caves in and result in death or serious personal
injury.
• Never direct discharged material toward anyone. Plan your mowing pattern to avoid discharge
of material toward bystanders, roads, sidewalks, windows, cars, and the like. Also, avoid
discharging material against a wall or obstruction, which may cause the material to ricochet
back toward the operator.
• Stop the blade when crossing gravel surfaces to avoid discharging gravel and rocks and drive
the mower slowly and carefully to avoid loss of control.
• Use extra care when approaching blind corners, shrubs, trees, or other objects that may block
your view.
• Never make any adjustments or repairs with the motor running and/or blades moving. Turn off
power switch and remove key.
• Stop the motor, set the parking pedal, wait until the blades come to a complete stop, and
remove start key before unclogging the side discharge chute or opening. The cutting blades
continue 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 blades have stopped rotating.
• If the mower should start to vibrate abnormally, stop the motor and check immediately for
the cause. Replace the blades if they are unevenly worn or damaged in any way. Vibration is
generally a sign of a damaged mower blade.
• Disengage mower blades when not mowing.
• Service on the product and charger must be performed by qualied repair personnel only.
Service or maintenance performed by unqualied personnel could result in injury to the user or
damage to the product.
• Use only authorized replacement parts when servicing the product. Use identical replacement
SAFETY INSTRUCTIONS

6
blades only. Use of unauthorized parts may create a risk of serious injury to the user or
damage to the product.
• Maintain or replace safety instructions labels, as necessary.
• Remove start key — Remove start key from the mower before storing, servicing, or changing
accessories such as blades. Such preventive safety measures reduce the risk of starting the
mower accidentally.
• Stop the unit and remove the start key when not in use. Transport the unit with the motor
stopped and the start key removed from the mower.
• Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards when not using your battery tool or when
changing accessories. Following this rule will reduce the risk of electric shock, re, or serious
personal injury.
• Do not use battery-operated mower in rain.
• Remove the start key before servicing, cleaning, or removing material from the gardening
appliance.
• Store idle lawn mower indoors — When not in use, mower should be stored indoors in a dry,
locked place out of the reach of children. The start key should also be removed and stored in
a separate location out of the reach of children.
• Follow instructions for lubricating and changing accessories.
• Only allow responsible adults, who are familiar with and understand the instructions, to
operate this machine.
• Never carry passengers.
• Never operate machine in a closed area.
• Do not mow in reverse unless absolutely necessary. Always look down and behind before and
while backing.
• Slow down before turning.
• Watch for trafc when operating near or crossing roadways.
• Use extra care when loading or unloading the machine into a trailer or truck and press the
brake pedal as needed to control the speed. The mower will freely roll if it is moved on an
inclined surface without pressing the brake pedal or setting the parking pedal. When loading
or unloading the mower, do not exceed the maximum recommended operation angle of 15°.
• Data indicates operators age 60 years and above are involved in a large percentage of riding
mower related injuries. These operators should evaluate their ability to operate the riding
mower safely enough to protect themselves and others from serious injury.
• Keep machine free of grass, leaves, or other debris build up. Allow machine to cool before
storing.
• Do not spray with a garden hose to clean. Use an air moving device, such as a compressor or
leaf blower to clean the mower.
• The bagger assembly (if equipped) is subject to deterioration and wear and should be checked
each time the mower is used. If replacement is needed, make sure the new bagger meets
original manufacturer’s recommendations and specications.
ADDITIONAL SAFETY RULES FOR BATTERIES
Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to
the eyes or skin. It may be toxic if swallowed.
• Do not dispose of the batteries in a re. The batteries could explode. Check with local codes
SAFETY INSTRUCTIONS

7
for possible special disposal instructions.
• When batteries are not in use, keep away from other metal objects like paper clips, coins,
keys, nails, screws, or other small metal objects that can make a connection from one terminal
to another. Shorting the battery terminals together may cause serious burns or a re.
• Exercise care in handling 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.
• Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes
in contact with your skin, wash immediately with soap and water. If liquid gets into your eyes,
ush them with clean water for at least 10 minutes, then seek immediate medical attention.
Following this rule will reduce the risk of serious personal injury.
• Do not charge battery in an area of extreme heat or cold. Batteries will charge best at
temperatures from 32˚F to 104˚F.
• Only use YARD FORCE Electric Riding Lawn Mower 75Ah (LPC12-75) lead acid battery.
ADDITIONAL SAFETY RULES FOR TOWING
• Use common sense when towing. Too heavy of a load while on a slope is dangerous. Tires can
lose traction with the ground and cause you to lose control of your mower.
• Follow manufacturer’s recommendations for wheel weights or counterweights.
• Total towed weight must not exceed the weight that you can safely control with the mower.
• Do not attach towed equipment except at the approved hitch point.
• Never allow children or others in or on towed equipment.
• Stopping distance increases with speed and weight of load being towed. Travel slowly and
allow extra time and distance to stop.
• Do not turn sharply when towing. Use additional caution when turning or operating under
adverse surface conditions. Use care when reversing.
