GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings, instructions, illustrations
and specitications provided with this power tool.
Failure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
WORK AREA SAFETY
■Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
■Do not operate power tools in explosive
atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
■Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
■Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk
of electric shock.
■Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded
■Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
■Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
■When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric
shock.
■If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of
electric shock.
PERSONAL SAFETY
■Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in
serious personal injury.
■Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injury.
■Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energising power tools that have the switch
on invites accidents.
■Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to
a rotating part of the power tool may result in personal
injury.
■Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power in
unexpected situations.
■Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
■If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
■Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
■Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
■Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with switch is dangerous and must be repaired.
■Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
■Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained

2
users.
■Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
■Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
■Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
■Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
■Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with
another battery pack.
■Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire
■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
burns or a fire.
■Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
■Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or
risk of injury.
■Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperatures above 130°C may cause explosion.
■Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
SERVICE
■Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that safety of the power tool is maintained.
■Never service damaged battery packs. Service
of battery packs should only be performedby the
manufacturer or authorized service providers.
CORDLESS HEDGE TRIMMER SAFETY
WARNINGS
■Keep all parts of the body away from the cutter
blade. Do not remove cut material or hold material
to be cut when blades are moving. Make sure the
switch is off when clearing jammed materials.
A moment of inattention while operating the hedge
trimmer may result in serious personal injury.
■Carry the hedge trimmer by the handle with cutter
blade stopped. When transporting or storing the
hedge trimmer, always fit the cutting device cover.
Proper handling of the hedge trimmer will reduce
possible personal injury from the cutter blades.
■Hold the power tool by insulated gripping surface
only, because the cutter blade may contact hidden
wiring. Cutter Blades contacting a “live” wire may make
exposed metal parts of the power tool “live” and could
give the operator an electric shock.
ADDITIONAL SAFETY WARNINGS
■Some regions have regulations that restrict the use of
the product. Check with your local authority for advice.
Read all instructions.
■Clear the work area before each use. Remove all
objects such as cords, lights, wire, or string which can
be thrown or become entangled in the cutting means.
■Check the hedge for foreign objects, such as wire
fences.
■Exercise additional caution when using the product
near posts, buildings, or other immovable objects.
■Beware of thrown objects. Keep all bystanders,
children, and pets at least 15 m away from work area.
Stop the product if anyone enters the area.
■Do not allow children or untrained individuals to use the
product.
■Do not operate the product in poor lighting. The
operator requires a clear view of the work area to
identify potential hazards.
■Ensure that all handles and guards are fitted when using
the hedge trimmer. Never attempt to use an incomplete
hedge trimmer or one fitted with an unauthorised
modification.
■Ensure before each use that all controls and safety
devices function correctly. Do not use the product if the
OFF switch does not stop the motor.
■Inspect the product before each use. Check for loose
fasteners, etc. Make sure that all guards and handles
are properly and securely attached. Replace any
damaged parts before use. Check for battery pack
leaks.
■Do not modify the product in any way.
■Wear full eye and hearing protection while operating the
product. If working in an area where there is a risk of
falling objects, wear appropriate head protection.
■Wear heavy, long trousers, boots, and gloves. Do not
wear loose-fitting clothing, short trousers, or jewellery of
any kind. Do not use the product with bare feet.

3
■Secure long hair so that it is above shoulder level to
prevent entanglement in moving parts.
■Use of hearing protection reduces the ability to hear
warnings (shouts or alarms). The operator must pay
extra attention to what is going on in the working area.
■Operating similar tools nearby increases both the risk
of hearing injury and the potential for other persons to
enter your working area.
■Do not use the product while tired, ill, or under the
influence of alcohol, drugs, or medication.
■Keep firm footing and balance. Do not overreach.
Overreaching can result in loss of balance and can
result in serious injury.
■Keep all parts of your body away from any moving part.
■Before starting the product, make sure that the cutting
blades will not come in contact with anything.
■While operating the hedge trimmer, always hold it firmly
with both hands by the two handles. Ensure that the
operating position is safe and secure. The manufacturer
does not recommend the use of steps or ladders. If
higher trimming is required, use an extended-reach
tool.
■Blades are sharp. When handling the blade assembly,
wear non-slip, heavy-duty protective gloves. Do not
place your hand or fingers between blades or in any
position where they could get pinched or cut. Never
touch the blade or service the product unless the
battery pack is removed.
■Turn off the product and remove the battery pack. Make
sure that all moving parts have come to a complete
stop, and allow the hedge trimmer to cool down:
●before adjusting the working position of the cutting
means
●before servicing
●before clearing a blockage
●before checking, cleaning, or working on the
product.
●before changing accessories
●before leaving the product unattended
●before checking for damage after striking a foreign
object
●before performing maintenance
●whenever the product starts to vibrate abnormally
■Do not force the product through heavy shrubbery. This
can cause the blades to bind and slow down. If the
blades slow down, reduce the pace.
■Do not attempt to cut stems or twigs that are larger
than 22 mm thick, or obviously too large to feed into the
cutting blade. Use a non-powered hand saw or pruning
saw to trim large stems.
■Do not operate the product with damaged or excessively
worn-out blades.
WARNING
If the product is dropped, suffers heavy impact, or begins
to vibrate abnormally, immediately stop the product and
inspect for damage or identify the cause of the vibration.
Any damage should be properly repaired or replaced by
an authorised service centre.

RESIDUAL RISKS
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
■injury caused by contact with the cutting means
–The blade cannot be guarded while cutting. Keep
the blade away from yourself and others. Cover it
with the blade protector when the product is not in
use.
■injury caused by vibration
–Always use the right tool for the job, use designated
handles, and restrict working time and exposure.
■hearing damage caused by exposure to noise
–Wear hearing protection and limit exposure.
RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the ngers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■Keep your body warm in cold weather. When operating
the product, wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
WARNING
Injuries may be caused, or aggravated, by prolonged
use of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
