specially important parts of the manual.
WARNING: Used if there is a risk of
injury or death for the operator or bystanders
if the instructions in the manual are not
obeyed.
CAUTION: Used if there is a risk of
damage to the product, other materials or

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.
• 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
4
609 - 009 - 15.09.2022
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.
• 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
609 - 009 - 15.09.2022

bystanders.
The risk increases in areas where it is not easy to see
the material that should be cut.
Do not cut with the area of the blade that is shown in
grey in the illustration. The speed and movement of the
blade can cause blade thrust. The risk increases with
the thickness of the stem that is cut.

Use less cutting pressure to fell large trees.
Brush cutting with a saw blade
To fell to the left, push the bottom of the tree to the right.
• Cut down thin trees and brush.
• Move the product from side to side.
• Cut many trees in one movement.
• For groups of thin trees:
a) Cut the outer trees high up.
b) Cut the outer trees to the correct height.
c) Cut from the center. If you cannot get access to
the center, cut the outer trees high up and let
them fall. This decreases the risk that the saw
blade becomes blocked.
To clear grass with a grass blade
1. Grass blades and grass cutters must not be used on
woody stems.
2. A grass blade is used for all types of tall or coarse
grass.
3. The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left
is the clearing stoke and the movement from left-to-
right is the return stoke. Let the left-hand side of the
blade (between 8 and 12 o'clock) do the cutting.
4. If the blade is angled to the left when clearing grass,
the grass will collect in a line, which makes it easier
to collect, e.g. by raking.
5. Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stoke and stand
firmly again.
6. Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the ground.
7. Reduce the risk of material wrapping around the
blade by always work at full speed and avoid the
previously cut material during the return stoke.
8. Stop the motor, unclip the harness and place the
machine on the ground before you start to collect the
cut material.
Grass trimming with a trimmer head
To trim the grass
1. Hold the trimmer head immediately above the
ground at an angle.
Do not push the grass trimmer line into the grass.
2. Decrease the length of the grass trimmer line by
10-12 cm (4-4.75 in) and decrease the motor speed
to decrease the risk of damage to plants.
22
609 - 009 - 15.09.2022
3. Use 80 % speed when you cut grass near objects.
To cut the grass
1. Make sure that the grass trimmer line is parallel to
the ground when you cut.
2. Do not push the trimmer head to the ground. The
ground and the product can be damaged.
3. Do not let the trimmer head touch the ground
continuously, it can cause damage to the trimmer
head.
4. Use full speed when you move the product from side
to side to cut grass.
Make sure that the grass trimmer line is parallel to
the ground.
To sweep the grass
The airflow from the rotating trimmer line can be used to
remove cut grass from an area.
1. Hold the trimmer head and the trimmer line parallel
to the ground and above the ground.
2. Apply full throttle.
3. Move the trimmer head from side to side and sweep
the grass.
WARNING:
