Safety
Safety definitions
Warnings, cautions and notes are used to point out
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
the adjacent area if the instructions in the
manual are not obeyed.
Note: Used to give more information that is necessary
in a given situation.
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. 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.
4967 - 002 - 11.06.2021

•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.
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.

Assembly
Power source for the product
To use full power output, the product must be connected
to a 32 A fuse. With a 16 A or a 25 A fuse the available
power output is lower. It is necessary to select an
applicable fuse in the remote control menu system.
At a lower voltage the available power output decreases
in a linear fall down to 80%. Refer to
Technical data on
page 17 for more information.
967 - 002 - 11.06.2021 7

Gasoline generator as a power source
CAUTION: A generator that supplies
more input voltage than specified in the
voltage range can cause damage to the
product.
A generator that operates on gasoline can be used as a
power source if it can supply sufficient power. Refer to
Technical data on page 17 for typical generator
operation conditions. The generator must be grounded
to prevent damage to the product.
To connect a power source to the product
CAUTION: Do not connect the product
to a power source without an applicable
fuse.
1. Connect the power cord from the power source to
the electric socket on the product.

capacity and the operation time of the remote control
battery. The operation time of the remote control battery
also decreases if the display is on.
Dispose a damaged remote control battery at your
nearest service center or recycle it at an applicable
location.
Remove and install the remote control battery from the
rear side of the remote control.
To charge the remote control battery
CAUTION: Keep the charger of the
remote control battery dry and in protection
against temperature variation.
1. Connect the charger to a socket outlet.
