SAFETY INFORMATION
• 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.
• Always wear proper eye protection that complies with ANSI Z87.1 in order 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 jewellery that can get caught in moving parts.
The wearing of protective gloves and safety footwear is recommended.
• Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or
outlet(s) that will be used to charge the lawn mower battery. Outlets with built-in GFCI
protection are available, and may be used as an added safety measure.
• Many injuries occur as a result 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.

SAFETY RULES FOR CHARGER
• Use of an attachment not recommended by the manufacturer may result in a risk of fire,
electric shock, or injury to persons. Following this rule will reduce the risk of electric shock,
re, or serious personal injury.
• Do not clean machine with isolator key or charger installed.
• Do not use the charger when the ambient temperature is above 40ºC or below 0ºC.
• Do not operate charger with a damaged cable or plug, which could cause shorting and electric
shock. Return to authorised service centre for repair or replacement.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged
in any way. Take it to an authorised service center for electrical check to determine if the
charger is in good working order.
BATTERY RULES FOR SAFETY
• Battery operated units do not have to be plugged into an electrical outlet; therefore, they are
always in operating condition. Be aware of possible hazards even when unit is not operating.
• Remove the battery pack before making any adjustments, cleaning, or removing material from
the unit.
• Ensure the isolator key is removed before inserting battery pack.
• A battery pack must be recharged only with the charger specied by the manufacturer. Using
a charger with an incompatible battery pack may create a risk of re. Use battery pack only
with charger listed.
• Use only battery pack intended specically for the machine. Use of any other battery packs
may result in a risk of re, electric shock, or injury to persons.
• 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 pack terminals together may cause sparks, burns, or a re.
• Do not place battery products or their batteries near re or heat. This will reduce the risk of
explosion and possibly injury.
• Do not open or mutilate the battery pack. Released electrolyte is corrosive and may cause
damage to the eyes or skin. It may be toxic if swallowed.
• Do not short-circuit the battery pack. There is danger of explosion.
• Protect the battery pack against moisture and water. Do not charge unit in a damp or wet
location. Following this rule will reduce the risk of electric shock.
• If electrolyte contacts the skin, wash it off immediately with water.
• If electrolyte contacts the eyes, ush thoroughly and immediately with water. Seek medical
attention.
• In case of damage and improper use of the battery, vapour may be emitted. Provide for
fresh air and seek medical help in case of complaints. The vapour can irritate the respiratory
system.
• Do not leave the battery pack in the car in the summer.
• Do not incinerate the battery.

• Do not disassemble charger, take it to an authorised service station if repair is required.
Incorrect reassemble may result in a risk of electric shock or re.
• Unplug charger from outlet before attempting any cleaning to reduce the risk of electric shock.
• Disconnect charger from the power supply when not in use to prevent damage to the charger
during a power surge.
• Do not expose machine to rain or wet conditions. Water entering charger will increase the risk
of electric shock.
• Make sure cable is located so that it will not be stepped on, tripped over, come in contact with
sharp edges or moving parts or otherwise subjected to damage or stress. This will reduce the
risk of accidental wash, which could cause injury, and damage to the cable, which could result
in electric shock.
• Keep cable and charger away from heat to prevent damage to housing or internal parts.
• Do not let gasoline/petrol, oils, petroleum-based products, etc. come in contact with plastic
parts. They contain chemicals that can damage, weaken, or destroy plastic.
• An extension cable should not be used for the charger unless absolutely necessary. Use of
improper extension cable could result in a risk of re and electric shock. If extension cord
must be used, make sure:
• That pins on plug of extension cord are the same number, size and shape as those of plug
on charger.
• That extension cord is properly wired and in good electrical condition.
W A R N I N G
If any parts are missing, do not operate unit until the missing parts are replaced. Failure to do
so could result in possible serious personal injury.
W A R N I N G
When transporting or servicing unit, always remove the key and battery.
W A R N I N G ( P R O P O S I T I O N 6 5 )
Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contains chemicals known to the state of California to cause cancer, birth 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-treated lumber.
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 lter out microscopic
particles.
