IMPORTANT
SAFETY
INSTRUCTIONS
Read all instructions
WARNING: When using electric
gardening appliances, basic safety
precautions should always be followed to
reduce the risk of fire, electric shock, and
personal injury, including the following:
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.
• 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 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.
4
1937 - 006 - 30.06.2023
• 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 a 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 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 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
tool 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
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 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 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
temperature above 130 °C may cause explosion.
1937 - 006 - 30.06.2023

• 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.
• Remove the battery pack from the tool before
making adjustments, changing accessories, or
storing the tool.Such preventive safety measures
reduce the risk of starting the battery tools
accidentally.
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.
Grass trimmer, brush cutter and brush saw
safety warnings
• Do not use the machine in bad weather conditions,
especially when there is a risk of lightning. This
decreases the risk of being struck by lightning.
• Thoroughly inspect the area for wildlife where the
machine is to be used. Wildlife may be injured by the
machine during operation.
• Thoroughly inspect the area where the machine is to
be used and remove all stones, sticks, wires, bones,
and other foreign objects. Thrown objects can cause
personal injury.
• Before using the machine, always visually inspect
to see that the cutter or blade and the cutter or
blade assembly are not damaged. Damaged parts
increase the risk of injury.
• Follow instructions for changing accessories.
Improperly tightened blade securing nuts or bolts
may either damage the blade or result in it becoming
detached.
• The rated rotational speed of the cutter must be at
least equal to the maximum rotational speed marked
on the machine. Cutters running faster than their
rated rotational speed can break and fly apart.
• Wear eye, ear, head and hand protection. Adequate
protective equipment will reduce personal injury by
flying debris or accidental contact with the cutting
line or blade.
• While operating the machine, always wear non-slip
protective footwear. Do not operate the machine
when barefoot or wearing open sandals. This
reduces the chance of injury to the feet from contact
with a moving cutter, line or blade.
• While operating the machine, always wear long
trousers. Exposed skin increases the likelihood of
injury from thrown objects.
• Keep bystanders away while operating the machine.
Thrown debris can result in serious personal injury.
•
Always use two hands when operating the machine.
Holding the machine with both hands will avoid loss
of control.
• Hold the machine by the insulated gripping surfaces
only, because the cutting line or blade may contact
hidden wiring. Cutting line or blades contacting
a "live" wire may make exposed metal parts of
the machine "live" and could give the operator an
electric shock.
• Always keep proper footing and operate the machine
only when standing on the ground. Slippery or
unstable surfaces may cause a loss of balance or
control of the machine.
• Do not operate the machine on excessively steep
slopes. This reduces the risk of loss of control,
slipping and falling which may result in personal
injury.
• When working on slopes, always be sure of your
footing, always work across the face of slopes, never
up or down and exercise extreme caution when
changing direction. This reduces the risk of loss
of control, slipping and falling which may result in
personal injury.
• Keep all parts of the body away from the cutter, line
or blade when the machine is operating. Before you
start the machine, make sure the cutter, line or blade
is not contacting anything. A moment of inattention
while operating the machine may result in injury to
yourself or others.
• Do not operate the machine above waist height. This
helps prevent unintended cutter or blade contact and
enables better control of the machine in unexpected
situations.
• When cutting brush or saplings that are under
tension, be alert for spring back. When the tension
in the wood fibres is released, the brush or sapling
may strike the operator and/or throw the machine out
of control.
• Use extreme caution when cutting brush and
saplings. The slender material may catch the blade
and be whipped toward you or pull you off balance.
• Maintain control of the machine and do not touch
cutters, lines or blades and other hazardous moving
parts while they are still in motion. This reduces the
risk of injury from moving parts.
• When clearing jammed material or servicing the
machine, make sure all power switches are off and
the power cord is disconnected. Unexpected starting
of the machine while clearing jammed material or
servicing may result in serious personal injury.
• Carry the machine with the machine switched off
and away from your body. Proper handling of the
machine will reduce the likelihood of accidental
contact with a moving cutter, line or blade.
• When transporting or storing the machine, always
fit the cover on metal blades. Proper handling of
the machine will reduce the likelihood of accidental
contact with the blade.
• Only use replacement cutters, lines, cutting heads
and blades specified by the manufacturer. Incorrect

replacement parts may increase the risk of breakage
and injury.
Blade thrust causes and related warnings
• Maintain a firm grip with both hands on the machine
and position your arms to resist blade thrust.
Position your body to the left side of the machine.
Blade thrust can increase the risk of injury due to the
machine moving unexpectedly. Blade thrust can be
controlled by the operator if proper precautions are
taken.
• If the blade binds, or when interrupting a cut for
any reason, switch the machine off and hold the
machine motionless in the material until the blade
comes to a complete stop. While the blade is
binding, never attempt to remove the machine from
the material or pull the machine backward while the
blade is in motion, otherwise blade thrust may occur.
Investigate and take corrective actions to eliminate
the cause of blade binding.
• Do not use blunt or damaged blades. Blunt or
damaged blades increase the risk of jamming or
catching on an object, resulting in blade thrust.
• Always maintain good visibility of the material being
cut. Blade thrust is more likely to occur in areas
where it is difficult to see the material being cut.
• If you are approached by another person while
operating the machine, switch the machine off.
There is an increased risk of injury to other persons
being struck by the moving blade in the event of
blade thrust.
