IMPORTANT SAFETY INSTRUCTIONS
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 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 reduce the
risk of starting the battery tools accidentally.

· Cut down thin trees and brush. · Move the product from side to side. · Cut
many trees in one movement. · For groups of thin trees:
609 – 009 – 15.09.2022
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.
53
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-
toright 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.

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.
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.
