SAFETY INFORMATION
GENERAL SAFETY RULES
WARNING: when using electric lawn mowers, basic safety precautions should always be
followed to reduce the risk of fire, electric shock, and personal injury, including the following:
READ ALL INSTRUCTIONS CAREFULLY
WARNING: This symbol indicates important safety instructions. If these instructions are not
followed, it could endanger the personal safety and/or property of the operator and others. Read
and understand all instructions in this manual before attempting to operate the mower. Failure to
comply with these instructions may result in personal injury.
DANGER
This mower was built to be operated according to the rules for safe operation that are contained
in this manual. As with any type of power equipment, carelessness or error on the part of the
operator can result in serious injury. This mower is capable of amputating body parts and
throwing objects. Failure to observe the following safety rules could result in serious injury or
death.
WARNING: Basic safety precautions should always be followed when using electric lawn mowers,
in order to reduce the risk of fire, electric shock, and personal injury.
WARNING: Use of this mower should be restricted to individuals who have read and understood
and will follow the warnings and instructions that are printed in this manual and on the mower.
• Carefully read all instructions on the mower and in the manual before attempting to assemble and
operate the mower. Keep this manual in a safe place for future reference and consult it regularly.
• Become familiar with all controls and their proper operation. Know how to stop the mower and
how to disengage the power in an emergency.
• In order to avoid contact with the blade or injury caused by a thrown object, stay in the
operating zone behind the handles, and keep children and bystanders at least 100’ (30 m) away
from the mower while it is in operation. Stop the motor immediately if someone enters the
mowing area.
• Thoroughly inspect the area where the mower is to be used. Remove all stones, sticks, wire,
bones, toys, and other objects that could be tripped over or thrown by the blade. Thrown objects
can cause serious personal injury.
• Plan your mowing pattern in such a way as to avoid discharging material toward roads,
sidewalks, bystanders, etc. Do not discharge material against a wall or obstruction. Doing so may
cause the discharged material to ricochet back toward the operator.

4
• Always wear proper eye protection that complies with ANSI Z87.1 to protect your eyes while
operating or performing any adjustment or repair. Thrown objects that ricochet can cause serious
eye injury.
• Always wear a face mask or a dust mask when operating the mower in a dusty environment.
• Dress properly. Do not wear loose clothing or jewelry that can get caught in moving parts. The
wearing of protective gloves and safety footwear is recommended.
• Many injuries occur because of the mower being pulled over the operator’s foot during a fall
caused by slipping or tripping. Do not operate this mower in bare feet, or while wearing sandals or
lightweight (e.g., canvas) shoes. Do not hold on to the mower if you are falling. Release the
handle immediately.
• Never pull the mower back toward you while you are walking. If you must back the mower away
from a wall or an obstruction, first look down and behind to avoid tripping, and then follow these
steps:
• Step back from the mower to fully extend your arms.
• Be sure that you are well balanced.
• Pull the mower back slowly.
• Do not use the mower for any job except that for which it is intended. Do not force the mower.
• Do not operate the mower while under the influence of alcohol or drugs.
• Stay Alert: Do not operate the mower when you are tired. Pay attention to what you are doing.
Use common sense.
• Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can
amputate hands and feet.
• Do not attempt to adjust the wheels or the cutting height while the motor is running.
• Avoid dangerous environments. Do not operate the mower in the rain or in wet or damp grass.
• Mow only in daylight or in good artificial light. Do not rush a mowing job.
• Stop the blade when crossing gravel driveways, walkways, or roads.
• If the mower starts to vibrate excessively, stop the motor, remove the battery and check for the
cause immediately. Vibration is generally a sign that the mower is not working properly or needs
repair.
• Stop the motor and wait until the blade comes to a complete stop before removing the grass
catcher or unclogging the chute. The cutting blade will continue to rotate for a few seconds after
the motor is shut off. Do not place any part of your body in the blade area until you are sure that
the blade has stopped rotating.
• Never operate mower without a proper trail shield, discharge cover, grass catcher, switch control,
or other safety device in place and in working order. Do not operate the mower with damaged
safety devices. Doing so can result in injury.
• Don’t force lawn mower. It will do the job better and safer at the rate for which it was designed.
• Store idle lawn mower indoors. When not in use, lawn mower should be stored in an indoor dry
and look-up place, out of reach of children.
• Maintain lawn mower. Keep cutting edges sharp and clean to ensure the best performance and
safety.

BATTERY & CHARGER
CAUTION: USE ONLY POWERSMART APPROVED REPLACEMENT BATTERIES, OTHER
BATTERIES MAY CAUSE INJURY OR DAMAGE TO THE MOWER. Use with POWERSMART
80V battery.
BATTERY SAFETY RULES
• 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, fire, or serious
personal injury.
• Do not place battery tools or their batteries near fire or heat. This will reduce the risk of
explosion and injury.
• Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has been
dropped or received a sharp blow. A damaged battery is subject to explosion. Properly dispose of
a dropped or damaged battery immediately.
• Batteries can explode in the presence of a source of ignition, such as a pilot light. To reduce the
risk of serious personal injury, never use any cordless product in the presence of open

6
flame.An exploded battery can propel debris and chemicals. If exposed, flush with water
immediately. Do not charge battery tool in a damp or wet location. Following this rule will
reduce the risk of electric shock.
• For best results, your battery tool should be charged in a location where the temperature is more
than 45°F but less than 104°F. To reduce the risk of serious personal injury, do not store outside
or in vehicles.
• 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, flush
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.
• When battery pack is not in use, keep it 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 sparks, burns, or a fire.
• Always remove battery pack from your tool when you are assembling parts, adjusting,
cleaning, or when not in use. Removing battery pack will prevent accidental starting that could
cause serious personal injury.
• Always remove battery pack before storing the device. When battery becomes fully charged,
unplug the charger from the power supply and remove the battery pack from the charger.
• Always wear eye protection with side shields marked to comply with ANSI Z87.1, along with
hearing protection. Failure to do so could result in objects being thrown into your eyes and other
possible serious injuries.
• Keep battery pack dry, clean, and free from oil and grease. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline, petroleum-based products, or any solvents to clean
battery pack.
• Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to
the eyes or skin. It may be toxic if swallowed.
PROPER CARE FOR BATTERY
Off-season storage
To obtain the longest possible battery life, we suggest the following:
• Remove the battery pack from the charger once it is fully charged and ready for use.
For battery pack storage longer than 30 days:
• Store the battery pack where the temperature is below 80°F and away from moisture.
• Store battery packs in a 30%-50% charged condition.
• Every two months of storage, charge the pack as normal.

defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treatedlumber.
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemical: work in a well ventilated area, and work with approved
safety equipment, such as those dust masks that are specially designed to filter out microscopic
particles.

mower will take approx. 3 seconds to get up to full speed. If the mower does not initially start:
Remove the battery and check under the mower deck to ensure there is nothing obstructing the blade
and that the blade can spin freely by hand. Even a small amount of grass on start up will prevent the
“soft-start” from turning the mower on.
Figure 8

18
CAUTION: Do not attempt to override the operation of the start button.
WARNING: The operation of any mower can result in foreign objects being thrown into the eyes,
which can cause severe eye damage. Always wear safety glasses while operating the mower and
while performing any adjustments or repairs.
WARNING: Ensure that other people and pets remain at least 100 ft (30 m) away when the mower is
in use.
INSPECT THE CUTTING AREA. Remove all stones, sticks, wires, bones, and other debris that
might be thrown by the rotating blades.
CUTTING HEIGHT ADJUSTMENT (See Figure 9)
When shipped, the wheels on the mower are set to the lowest cutting position. Before using the
mower for the first time, raise the cutting position to the height best suited for your lawn. The
average lawn should be between 1.18" to 2" during cool months and between 2" and 3" during hot
months.
To adjust the blade height:
• To raise the blade height, grasp the rear height adjustment lever (1), then move it. Adjust the
mowing height according to the position indication of front and rear seats. The larger the number,
the higher the gear.
Figure 9

19
WARNING: Slopes are a major factor related to accidents involving slips and falls, which can result
in severe injury. Operating the mower on a slope requires extra caution. If you feel uneasy on a
slope, do not mow it. For your safety, use the slope gauge that is included as part of this manual to
measure slopes before operating this unit on a sloped or hilly area.
• Mow across the face of a slope, and never up and down. Exercise extreme caution when
changing direction on a slope.
• Watch for holes, ruts, rocks, hidden objects, or bumps that may cause a slip or a trip. Tall grass
can hide obstacles.
• Always be sure of your footing. If you feel like you are losing your balance, release the blade/
motor control handle immediately. The blade will stop rotating within 3 seconds.
• Do not mow near drop-offs, ditches, or embankments, because you could lose your footing or
balance.
• Do not mow a slope that has an angle of greater than 15°, as determined using the slope gauge.
• Do not mow wet or damp grass. Unstable footing can cause slipping.
WARNING: Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2
1/2’ [.75 m] every 10’ [3 m]). Mow across the face of a slope, and never up and down.
Fig.10

MOWING TIPS
NOTE: A sharp blade will greatly enhance the performance of the mower, especially when cutting high grass.
Be sure to check the blade and to sharpen it at least once per year, as described in the Maintenance section.
• Verify that the lawn is\ free of stones, sticks, wires, and other objects that could damage the
blades or the motor. These objects could be accidentally thrown by the mower in any direction
and could cause serious personal injury to the operator and to others. To prevent electric shock,
do not operate the mower in damp or wet conditions.
• Do not mow in circles. Travel back and forth across the lawn.
• When cutting thick grass, reduce walking speed to allow for a more effective cut and a proper
discharge of the clippings.
• For a healthy lawn, always cut off one-third or less of the total length of the grass. The average
lawn should be approximately 1 1/2 to 2” (3.8 to 5 cm) long during cool months, and between 2"
to 3" (5 cm to 8.3 cm) long during hot months.
• MULCHING TIPS
NOTE: INSPECT THE AREA WHERE THE MOWER IS TO BE USED, AND REMOVE ALL STONES,
STICKS, WIRE, BONES, AND OTHER DEBRIS THAT MIGHT BE THROWN BY THE ROTATING BLADE.
• Release the switch to turn the mower OFF when crossing any graveled area (stones can be
thrown by the blade).
• Set mower to the highest cutting height when mowing on uneven ground or in tall weeds.
• For effective mulching, do not cut wet grass, because it tends to stick to the underside of
the deck, preventing proper mulching of grass clippings. New or thick grass may require a
narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing
has been delayed and the grass has been allowed to grow longer than 4" (10 cm), mow the
lawn twice in order to reduce the grass height to a maximum of 3” (8.3 cm).
• Walk at a steady pace. Overlap the cutting rows. Do not let the grass get too tall. If the grass
gets too long, start at the highest cutting position, and work down to the desired cutting height.
WARNING: If you strike a foreign object, stop the motor, and remove the battery. Thoroughly
inspect the mower for any damage. Repair any damage before operating the mower. Excessive
vibration of the mower during operation is an indication of damage. Thoroughly inspect the mower
and repair any damage before operating the mower.
