2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to follow all instruc-
tions 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.

4 English 2381016 *2381016*
▶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 an 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 a 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

*2381016* 2381016 English 5
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 irritation 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 (265 °F) may cause
explosion.
▶Follow all charging instructions and do not charge the battery pack
or tool outside the temperature range specified in the instructions.

6 English 2381016 *2381016*
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.
2.2 Additional safety instructions
▶Use the product and accessories only when they are in perfect working
order.
▶Never tamper with or modify the product or accessories in any way.
▶Risk of injury due to falling tools and/or accessories. Before starting
work, check that the battery and installed accessories are secure.
▶Do not touch oscillating parts - risk of injury!
▶Wear eye protection, a hard hat and ear protection and suitable respira-
tory protection while the product is in use.
▶Dust produced by grinding, sanding, cutting and drilling can contain
dangerous chemicals. Some examples are: lead or lead-based paints;
brick, concrete and other masonry products, natural stone and other
products containing silicates; certain types of wood, such as oak,
beech and chemically treated wood; asbestos or materials that contain
asbestos. Determine the exposure of the operator and bystanders
by means of the hazard classification of the materials to be worked.
Implement the necessary measures to restrict exposure to a safe level,
for example by the use of a dust collection system or by the wearing
of suitable respiratory protection. The general measures for reducing
exposure include:
▶working in an area that is well ventilated,
▶avoidance of prolonged contact with dust,
▶directing dust away from the face and body,
▶wearing protective clothing and washing exposed areas of the skin
with water and soap.
▶Do not look directly into the light source (LEDs) incorporated in the power
tool and do not direct the light at other persons’ faces.
▶Take frequent breaks and do physical exercises to improve the blood
circulation in your fingers. High vibration during long periods of work can
lead to disorders of the blood vessels and nervous system in the fingers,
hands and wrists.
▶Keep the air vents clear at all times. Risk of burn injuries due to blocked
air vents!

*2381016* 2381016 English 7
▶Use clamps or some other suitable means to firmly secure the workpiece
to a stable supporting surface. Holding the workpiece only by hand or
against your body leaves it unstable, which can lead to loss of control.
▶Before beginning work, check the working area for concealed electric
cables or gas and water pipes. External metal parts of the product could
give you an electric shock or cause an explosion if you accidentally
damage an electric cable or a gas or water pipe.
▶Use the product for dry sanding/grinding only. Water entering a power
tool will increase the risk of electric shock.
▶Do not attempt to scrape off moistened materials (e.g. wallpaper) and do
not perform scraping work on damp underlying materials. Water entering
a power tool will increase the risk of electric shock.
▶Do not pretreat the surface to be worked with liquids that contain
solvents. The heat generated in the materials during scraping operations
can result in the production of toxic vapors.
▶Keep your hands away from the cutting area. Do not reach underneath
the workpiece. Risk of injury due to contact with the saw blade.
▶Always hold the product firmly with both hands and keep a firm footing
at all times. The product is guided more safely by two hands.
▶Wear protective gloves when changing the accessory tool. The accessory
tool runs hot when in use and there is a risk of burn injury.
▶Remove dirt, chips and other foreign matter that adheres to the accessory
tool and/or the tool mount. Otherwise the accessory tool cannot be
tightened correctly.
▶Switch the product on only after you have brought it to the working
position. Switch the product on only when the accessory tool is not in
contact with the workpiece.
▶Wait until the product has come to a complete stop before you lay it
down.
▶Do not use accessories not specifically intended and recommended for
this power tool by the tool manufacturer. The fact that an accessory can
be attached to the power tool does not necessarily mean that it can be
used safely.
2.3 Careful handling and use of batteries
▶Comply with the following safety instructions for the safe handling
and use of Li-ion batteries. Failure to comply can lead to skin irritation,
severe corrosive injury, chemical burns, fire and/or explosion.
