General power tool safety warnings
WARNING: Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool. Failure to
follow all instructions listed below may result
in electric shock, fire and/or serious injury.
WARNING: Make sure to read the
approved accessory manual together with
this power unit's manual.
Note: Save all warnings and instructions for future
reference. 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 machines in explosive atmospheres,
such as in the presence of flammable liquids, gases
or dust.Machines create sparks which may ignite the
dust or fumes.
•
Keep children and bystanders away while operating
a machine. Distractions can cause you to lose
control.
Electrical safety
• Machine plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs
with earthed (grounded) machines. 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 machines to rain or wet conditions.
Water entering a machine will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the machine. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk
of electric shock.
• When operating a machine 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 machine in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of a RCD reduces the risk of
electric shock.
Personal safety
• Stay alert, watch what you are doing and use
common sense when operating a machine. Do not
use a machine while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating machines 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 injuries.
• 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 machine. Carrying machines with your finger
4
2129 - 005 - 22.04.2025
on the switch or energising machines that have the
switch on invites accidents.
• Remove any adjusting key or wrench before turning
the machine on. A wrench or a key left attached to
a rotating part of the machine may result in personal
injury.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the
machine in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing 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
machines allow you to become complacent and
ignore machine 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 the switch is dangerous and must be
repaired.
• Disconnect the plug from the power source and/or
remove the battery pack, if detachable, 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
users.
• Maintain power tools and accessories. 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 irritations or burns.
• Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior 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
temperature above 130 ºC (265 ºF) 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 the safety of the power tool is
maintained.
• Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.
Hedge trimmer safety warnings
• Keep all parts of the body away from the blade. Do
not remove cut material or hold material to be cut
when blades are moving. Blades continue to move
after the switch is turned off. A moment of inattention
while operating the hedge trimmer may result in
serious personal injury.
• Carry the hedge trimmer by the handle with the
blade stopped and taking care not to operate any
power switch. Proper carrying of the hedge trimmer
will decrease the risk of inadvertent starting and
resultant personal injury from the blades.
2129 - 005 - 22.04.2025

• When transporting or storing the hedge trimmer,
always fit the blade cover. Proper handling of the
hedge trimmer will decrease the risk of personal
injury from the blades.
• When clearing jammed material or servicing the
unit, make sure all power switches are off and
the battery pack is removed or disconnected.
Unexpected actuation of the hedge trimmer while
clearing jammed material or servicing may result in
serious personal injury.
• When clearing jammed material or servicing the unit,
make sure all power switches are off and the lock-off
is in the locked position. Unexpected actuation of
the hedge trimmer while clearing jammed material or
servicing may result in serious personal injury.
• Hold the hedge trimmer by insulated gripping
surfaces only, because the blade may contact
hidden wiring. Blades contacting a "live" wire may
make exposed metal parts of the hedge trimmer
"live" and could give the operator an electric shock.
• Keep all power cords and cables away from cutting
area. Power cords or cables may be hidden in
hedges or bushes and can be accidentally cut by the
blade.
• Do not use the hedge trimmer in bad weather
conditions, especially when there is a risk of
lightning. This decreases the risk of being struck by
lightning.
Extended-reach hedge trimmer safety warnings
• To reduce the risk of electrocution, never use the
extended-reach hedge trimmer near any electrical
power lines. Contact with or use near power lines
may cause serious injury or electric shock resulting
in death.
• Always use two hands when operating the extended-
reach hedge trimmer. Hold the extended-reach
hedge trimmer with both hands to avoid loss of
control.
• Always use head protection when operating the
extended-reach hedge trimmer overhead. Falling
debris can result in serious personal injury.
