understand the operator's manual.

WARNING

Do not attempt to operate this mower until you have read
thoroughly and understood completely all instructions,
safety rules, etc. contained in this manual. Failure to
comply may result in accidents involving electric shock,
re, and/or serious personal injury.

When using battery operated machine basic safety
precaution should always be followed to reduce the risk
of re, leaking batteries and personal injury.

PERSONAL SAFETY

■ This lawn mower is capable of amputating hands and
feet, and throwing objects. Failure to observe all safety
instructions could result in serious injury or death.

■ Never allow children or people unfamiliar with the
instructions to use the machine. Local regulations may
restrict the age of the operator.

■ Stay alert, watch what you are doing, and use common
sense when operating the lawn mower. Do not operate
the mower while tired or under the influence of drugs,
alcohol, or medication. A lapse in concentration while
operating the machine may result in serious personal

injury.

■ Wear heavy, long trousers, long sleeves, boots,
and gloves. Do not wear loose fitting clothing, short
trousers, sandals, or go barefoot.

■ Always wear safety glasses with side shields. Use
face mask if operation is dusty.

■ Always be sure of your footing. Keep firm footing and
balance. Do not overreach. Overreaching can result in
loss of balance.

■ Walk, never run.

■ Mow across the face of slopes, never up and down.
Exercise extreme caution when changing direction on
slopes.

■ Do not mow near drop-offs, ditches, excessively steep
slopes, or embankments. Poor footing could cause a
slip and fall accident.

■ Plan your mowing pattern to avoid discharge of
material toward roads, public pavements, bystanders
and the like. Also, avoid discharging material against
a wall or obstruction, which may cause the material to
ricochet back toward the operator.

WORK AREA SAFETY

■ Never mow while people, especially children, or pets
are nearby.

■ Always mow in the daylight or in good artificial light.

■ Do not operate the machine in explosive atmospheres,
such as in the presence of flammable liquids, gases
or dust. The tool create sparks which may ignite the
dust or fumes.

■ Objects struck by the lawn mower blade can cause
severe injuries to persons. Thoroughly inspect the
area where the machine is to be used and remove all
rocks, sticks, metal, wire, bones, toys, or other foreign
objects.

■ Do not operate the machine in wet grass or in the rain.

■ Keep in mind that the operator or user is responsible
for accidents or hazards occurring to other people or
their property.

■ 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 under the
watchful care of a responsible adult other than the
operator.

■ Be alert and turn mower off if a child enters the area.

■ Never allow children or people unfamiliar with the
instructions to use the machine.

■ Use extra care when approaching blind comers,
shrubs, trees, or other objects that may block your

view.

■ Keep work area clean.

■ Keep work area well lit.

■ Cluttered or dark areas invite accidents.

GARDEN TOOLS USE AND CARE

■ Before using, always visually inspect to ensure blades,
blade bolts, and cutter assembly are not worn or
damaged.

■ Replace worn or damaged blades and bolts in sets to
preserve balance.

■ Check all nuts, bolts, and screws at frequent intervals
for proper tightness to be sure the equipment is in safe
working condition.

■ Check the grassbox frequently for wear or
deterioration.

■ Replace worn or damaged parts.

■ Do not force the machine. It will do the job better and
safer at the speed for which it was designed.

■ Do not overload your mower. Mowing long thick grass
may cause the motor speed to drop, or the power to
cut out. When mowing in long thick grass a first cut
with the cutting height set higher will help reduce the
load. See adjusting the blade height.

■ Please note that cutting long grass will drain the
battery quicker than cutting shorter grass.

■ Stop the blade when crossing gravel surfaces.

■ Do not pull the mower backward unless absolutely
necessary. If you must back the machine away from a
wall or obstruction, first look down and behind to avoid
tripping or pulling the machine over your feet.

■ Stop the blade(s) if the machine has to be tilted for
transportation when crossing surfaces other than
grass, and when transporting the machine to and from
the area to be mowed.

■ Never operate the machine with defective guards
or shields, or without safety devices, for example,
deflectors and/or grassboxes, in place.

■ Switch on the motor according to instructions and
keep hands and feet away from cutting area. Keep
clear of the discharge opening at all times.

■ Never pick up or carry a lawnmower while the engine
is running.

■ Remove isolator key for the below cases:

● whenever you leave the machine

● before cleaning a blockage

● before checking, cleaning or working on the
machine

● after striking a foreign object; inspect the appliance
for damage and make repairs as necessary

● before clearing the grassbox

● if the machine starts to vibrate abnormally (check
immediately)

● when not in use and storing the machine

● when recharging and removing/inserting battery
pack

■ Avoid holes, ruts, bumps, rocks, property stakes, or
other hidden objects. Uneven terrain could cause a
slip and fall accident.

■ If the machine should start to vibrate abnormally,
stop the motor and check immediately for the cause.
Replace the blade if it is unevenly worn or damaged in
any way. Vibration is generally a warning of trouble.

■ If the machine strikes a foreign object, follow these
steps:

● Stop the machine by releasing the power lever,
wait until the blade comes to a complete stop, and
then remove isolator key.

● Thoroughly inspect the machine for any damage.

● Replace the blade if it is damaged in any way.
Repair any damage before restarting and
continuing to operate the mower.

● Use the right appliance. Do not use the machine
for any job except that for which it is intended.

battery pack.

■ A battery pack must be recharged only with the charger
specified by the manufacturer. Using a charger with
an incompatible battery pack may create a risk of fire.
Use battery pack only with charger listed.

■ Use only battery pack intended specifically for the
machine. Use of any other battery packs may result in
a risk of fire, 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 fire.

■ Do not place battery products or their batteries near
fire 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.

with water.

■ If electrolyte contacts the eyes, flush 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.

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, fire, 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

■ 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.

■ 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 fire.

■ 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 fire and electric
shock. If extension cable must be used, make sure:

● That pins on plug of extension cable are the
same number, size and shape as those of plug on
charger.

● That extension cable is properly wired and in good
electrical condition.
