2 Safety Instructions
WARNING
Read all safety instructions, instructions, illustrations and technical
specifications provided for this power tool.
Failure to observe the following instructions can result in electric shock, fire
and/or serious injuries.
Keep all safety instructions and precautions for future reference.
The term “power tool” used in the safety instructions refers to mains-operated
power tools (with mains power lead) or battery-operated power tools (without
mains power lead).
2.1 Workplace safety
a) Keep your work area clean and well illuminated.
Untidiness and unlit work areas can result in accidents.
b) Never use the power tool in potentially explosive environments containing
flammable liquids, gases or dusts.
Power tools generate sparks which can ignite dust or vapours.
c) Keep children and other persons away from the power tool during use.
A moment’s distraction can cause you to lose control of the power tool.
2.2 Electrical safety
a) The connecting plug of the power tool must fit in the plug socket. The plug
must not be modified in any way. Do not use adapter plugs in conjunction
with power tools with protective earth conductor.
Unmodified plugs and properly fitting plug sockets reduce the risk of electric shock.
b) Avoid physical contact with earthed surfaces such as pipes, heaters,
cookers and refrigerators.
There is an increased risk of an electric shock if your body is earthed.
c) Keep power tools away from rain and moisture.
The ingress of water into a power tool increases the risk of an electric shock.
d) Do not misuse the connection cable in any way by using it to carry or hang
up the power tool or to pull the plug out of the socket. Keep the connection
cable away from heat, oil, sharp edges and moving machine parts.
Damaged or kinked connection cables increase the risk of an electric shock.

EN
A
BDN 20 | EN | ID No. 10154 | V01 | 2021-11 | 9 |
e) When working with a power tool outdoors, use only extension leads that are
suitable for outdoor use.
Use of an extension lead suitable for outdoor use reduces the risk of electric
shock.
f) If the use of the power tool in a damp environment is unavoidable, use a
residual-current circuit breaker.
Use of a residual-current circuit breaker (RCCB with 10 mA maximum tripping
current) reduces the risk of an electric shock.
2.3 Safety of people
a) Always work carefully, attentively and sensibly when using a power tool. Do
not use the power tools if you are tired or are under the influence of drugs,
alcohol or medication.
A moment of inattention while using the power tool can result in serious injuries.
b) Wear personal protective equipment and always wear goggles.
The wearing of personal protective equipment, such as dust mask, non-slip safety
shoes, helmet or ear protectors, depending on the type and application of the
power tools, reduces the risk of injuries.
c) Avoid accidental switching on of the power tool. Ensure that the power tool
is switched off before connecting it to the mains power supply and/or
connecting the battery and before picking up or carrying the tool.
If you have your finger on the switch when carrying the power tool or you connect
the tool to the power supply when it is switched on, this can lead to accidents.
d) Remove the adjusting tools or wrenches before switching on the power tool.
A tool or wrench in a rotating part of the power tool can result in injuries.
e) Avoid abnormal postures when working. Ensure you are standing firmly and
maintain your balance at all times.

b) Do not use a power tool whose switch is defective.
A power tool which can no longer be switched on or off is dangerous and must be
repaired.
c) Remove the plug from the plug socket and/or remove a removable
rechargeable battery before carrying out tool adjustments, changing insert
tools or placing the power tool aside.
This precautionary measure prevents unintentional starting of the power tool.
d) Store power tools out of the reach of children when not in use. Do not allow
people to use the power tool if they are not familiar with it or if they have not
read this instruction manual.
Power tools are dangerous if they are used by inexperienced people.
e) Maintain power tools and insert tools with care. Check whether moving parts
are in proper working order and do not jam, whether parts are broken or
damaged in such a way that they impair the function of the power tool. Have
damaged parts repaired before using the power tool.
Many accidents are caused by poorly serviced and maintained power tools.
f) Keep cutting tools sharp and clean at all times.
Carefully maintained cutting tools with sharp cutting edges jam less easily and are
easier to control.
g) Use the power tool, insert tools, etc. in accordance with this instruction
manual. Take into consideration the working conditions and the work to be
carried out.
Use of power tools other than the intended applications can lead to dangerous
situations.
h) Keep the handles and gripping surfaces dry, clean and free from oil and
grease.
Slippery handles and gripping surfaces prevent safe operation and control of the
power tool in unforeseen situations.
2.5 Using and handling the battery pack
a) Only use chargers recommended by the manufacturer to charge the
rechargeable batteries.
There is a risk of fire if a charger that is suitable for a certain type of rechargeable
batteries is used to charge other rechargeable batteries.
b) Use the intended rechargeable batteries only in the power tools.
Use of other rechargeable batteries can cause injuries and a risk of fire.

EN
A
BDN 20 | EN | ID No. 10154 | V01 | 2021-11 | 11 |
c) While it is not in use, keep the rechargeable battery away from paper clips,
coins, keys, nails, screws or other small metal objects that could cause
bridging of the contacts.
Leaking battery fluid can cause skin irritation or burns.
d) Incorrect use can cause fluid to leak from the rechargeable battery. Avoid
contact with the fluid. In case of accidental contact, rinse off with water. If
the fluid gets in the eyes, seek medical help.
Leaking battery fluid can cause skin irritation or burns.
e) Do not use damaged or modified rechargeable batteries.
Damaged or modified rechargeable batteries can behave in an unforeseeable way
and lead to fire, explosion or a risk of injury.
f) Do not expose a rechargeable battery to fire or high temperatures.

spare parts only.
This will ensure that the safety of the power tool is maintained.
b) Never service damaged rechargeable batteries.
All servicing of rechargeable batteries should only be carried out by the
manufacturer or authorised customer service agents.
2.7 Safety instructions for abrasive cutting (disc cutting)
applications
a) The protective hood belonging to the power tool must be attached securely
and set to achieve maximum safety, i.e. smaller part of the grinding body is
open in the direction of the operator. Keep yourself and people nearby
outside the level of the rotating grinding disc.
The protective hood is intended to protect the operator from fragments and
accidental contact with the abrasive product.
b) Only use bonded, reinforced or diamond coated cutting discs with your
power tool.
Just because you can attach the accessories to your power tool is not a guarantee
of safe use.
c) The approved speed of the insert tool must be at least as high as the
maximum speed given on the power tool.
Accessories which rotate faster than approved can break and fly off the tool.

EN
| 12 | ABDN 20 | EN | ID No. 10154 | V01 | 2021-11
d) Abrasive products may only be used for their recommended use options.
E.g.: never grind with the side (circular face) of a cutting disc.
Cutting discs are intended for removing material with the edge of the disc. Lateral
forces applied to these abrasive products can cause them to break.
e) Always use undamaged mounting flanges of the correct size and form for the
grinding disc chosen by you.
Suitable flanges support the grinding disc and thus reduce the risk of grinding disc
fracture.
f) Do not use worn grinding discs of large power tools.
Grinding discs for larger power tools are not designed for the higher speeds of
smaller power tools and can break.
g) The outer diameter and thickness of the insert tool must correspond to the
dimensions of your power tool.
Incorrectly dimensioned insert tools cannot be adequately shielded or controlled.
h) Grinding discs and flanges must precisely match the grinding spindle of
your power tool.
Insert tools which do not precisely fit on the rotating spindle of the power tool rotate
irregularly, vibrate severely and can result in loss of control.
i) Never use damaged grinding discs. Before each use, check the grinding
discs for splinters and cracks. If the power tool or grinding disc is dropped
or falls, check whether it is damaged, or use an undamaged grinding disc. If
you have checked and inserted the grinding disc, keep yourself and other
people nearby outside the level of the rotating grinding disc and let the tool
run at maximum speed for one minute.
Most damaged grinding discs break during this test period.
j) Wear personal protective equipment. Depending on the task for which the
tool is used, wear full face protection, eye protection or goggles. If
appropriate, wear a dust mask, ear protectors, safety gloves or a special
apron, which keeps cutting debris, abrasive and material particles away from
you.
Your eyes should be protected against flying foreign bodies which result during
various applications. A dust or breathing mask must filter any dust produced during
the application. If you are exposed to loud noise for a long time, you can suffer
from loss of hearing.
k) Ensure other people keep a safe distance from your work area. Any person
entering the work area must be wearing personal protective equipment.
Broken pieces of the workpiece or broken insert tools can fly off and cause injuries,
even outside the immediate work area.
l) Hold the tool by the handle gripping surfaces only when carrying out work
during which the insert tool can hit concealed electrical cables.
Contact with a live conductor can also energise metal parts of the tool and cause
an electric shock.

EN
A
BDN 20 | EN | ID No. 10154 | V01 | 2021-11 | 13 |
m) Never put down the power tool until the insert tool has come to a complete
standstill.
The rotating insert tool can come into contact with the surface on which the power
tool is placed, which could cause you to lose control of the power tool.
n) Do not leave the power tool running while you are carrying it.
Your clothing can get caught by inadvertent contact with the rotating insert tool and
the insert tool can drill into your body.
o) Regularly clean the ventilation slots of your power tool.
The motor fan draws dust into the housing and a large accumulation of metal dust
can cause electrical hazards.
p) Do not use the power tool near flammable materials.
Sparks could ignite these materials.
q) Do not use any insert tools which require liquid coolant.
The use of water or other liquid coolants could result in an electric shock.
2.8 Kickback and corresponding safety instructions
Kickback is the sudden reaction caused by a rotating grinding disc that gets caught or
is blocked. Entanglement or blocking results in the abrupt stopping of the rotating insert
tool. This causes an uncontrolled power tool to be accelerated against the direction of
rotation of the insert tool at the blocking point.
For example, if a grinding disc gets stuck in the workpiece or becomes blocked, the
edge of the grinding disc that is immersed in the workpiece can get caught and
therefore break out the grinding disc or cause kickback. The grinding disc then moves
towards or away from the person using the tool, depending on the direction of rotation
of the disc at the blocking point. Grinding discs can also break here.
Kickback is the consequence of incorrect or faulty use of the power tool. It can be
prevented by taking suitable precautions, as described in the following.
a) Hold the power tool firmly and position your body and arms so that you can
absorb the kickback forces. Always use the additional handle, if available, to
ensure you have the greatest possible control over kickback forces or
reaction torque while the tool is starting up.
The person using the tool can control the kickback and reaction forces by taking
suitable precautions.
b) Never place your hand near rotating insert tools.
The insert tool can move across your hand during kickback.
c) Keep away from the area in front of and behind the rotating cutting disc.
The kickback drives the power tool in the opposite direction to the movement of the
grinding disc at the blocking point.
d) Take particular care when working in the area of corners, sharp edges, etc.
Prevent insert tools from rebounding from the workpiece and jamming.
The rotating insert tool tends to get stuck in corners, sharp edges or if it rebounds.
This causes loss of control or kickback.

EN
| 14 | ABDN 20 | EN | ID No. 10154 | V01 | 2021-11
e) Never use a chain or toothed saw-blade or segmented diamond disc with
more than 10 mm wide slots.
Such insert tools frequently cause kickback or loss of control of the power tool.
f) Avoid blocking of the cutting disc or excessive contact pressure. Do not
make any excessively deep cuts.
Overloading the cutting disc increases the stresses on it and its susceptibility to
cant or blocking and therefore possibility of kickback, or causes the abrasive
product to break.
g) If the cutting disc sticks or you interrupt the work, switch off the tool and
keep it still until the disc has stopped moving. Never attempt to pull the still
running cutting disc out of the cut, otherwise kickback can occur.
Determine and remove the cause of the jamming.
h) Do not switch the power tool back on while it is still in the workpiece. Allow
the cutting disc to reach its full speed first before carefully continuing with
the cut.
Otherwise the disc can pinch, jump out of the workpiece or cause kickback.
i) Support slabs, boards or large workpieces to reduce the risk of kickback due
to a jammed cutting disc.
Large workpieces can sag under their own weight. The workpiece must be
supported on both sides of the disc, not only near the cut but also at the edge.
j) Be especially cautious in case of "pocket cuts" in existing walls or other
concealed areas.
The plunging cutting disc can cause kickback when cutting gas or water pipes,
electric cables or other objects.
2.9 Further safety instructions for wall chasing
2.9.1 Safety instructions for all work
xWear hearing protection when abrasive cutting (disc cutting).
Exposure to noise can cause loss of hearing.
