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.

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.
This will enable you to control the power tool better in unexpected situations.
f) Wear suitable clothing. Do not wear loose clothing or jewellery. Keep your
hair, clothing and gloves away from moving parts.
Loose clothing, jewellery and long hair can get caught in moving parts.
g) If dust extractor and collection equipment can be mounted, they must be
connected and used correctly.
Use of a dust extraction system can reduce the hazards caused by dust.
h) Don’t be lulled into a false sense of safety and do not break the safety rules
for power tools even if, after much use, you are familiar with the power tool.
Careless action can cause severe injuries within fractions of a second.

| 10 | ABDN 20 | EN | ID No. 10154 | V01 | 2021-11
2.4 Using and handling the power tool
a) Do not overload the power tool. Use the intended power tool for your work.
You work better and safer within the given power range if you use the suitable
power tool.
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.
