General safety instructions for power tools
WARNING
Read all the safety instructions and precautions.
Failure to observe the safety instructions and precautions 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) and battery-operated power tools (without mains power cable).
1) Safety at the place of work
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 machine.
2) Electrical safety
a) The connecting plug of the power tool must fit into 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 misuse the 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 cable away from heat, oil, sharp
edges and moving machine parts.
Damaged or kinked cables increase the risk of an electric shock.
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 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 cur-
rent) reduces the risk of an electric shock.

For your Safety
3) Safety of persons
a) Always work carefully, attentively and sensibly when using a power tool. Do
not use power tools if you are tired or are under the influence of drugs, alco-
hol 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.
Use 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 connect-
ing 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 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 extraction and collection devices can be installed, ensure that these
are connected and are used correctly.
Use of a dust extraction system can reduce the hazards caused by dust.
4) Using and handling the power tool
a) Do not overload the tool. Use the power tool intended for your work.
You work better and safer within the given power range if you use a 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 the battery before carry-
ing out tool adjustments, changing accessories or placing the tool aside.
This precautionary measure prevent unintentional starting of the power tool.

6
For your Safety
d) Store power tools out of the reach of children when not in use. Do not allow
people to use the tool unless they are 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 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 re-
paired before using the 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, accessories, insert tools/bits, etc. in accordance with this
instruction manual. Take into consideration the working conditions and the
work to be carried out.
Use of power tools for any purpose other than the intended uses can lead to dan-
gerous situations.
5) Service
a) Have your power tool repaired only by qualified personnel and only using
original spare parts.
This will ensure that the safety of the power tool is maintained.
Machine-Specific Safety Instructions
Operating personnel requirements
People below the age of 16 may not use the machine.
Workplace safety
Watch out for open and concealed electricity cables, and water and gas pipes.
Use suitable detectors to find concealed utility pipes and cables, or contact
the local utility company for advice.
Contact with electricity cables can cause fires and an electric shock. Damage to a
gas pipe can cause an explosion. Penetrating a water pipe causes damage to prop-
erty or could cause an electric shock.
Secure the workpiece.
A workpiece securely held in clamping devices or a vice is more safely held than in
the hand.
Avoid dust accumulation in the workplace.
Dusts can easily ignite.
Ensure adequate ventilation in closed rooms.
Risk due to dust emission and visual impairment.

7
For your Safety
Dust from materials such as coatings containing lead, several types of wood,
minerals and metal can be harmful to health and cause allergic reactions,
respiratory diseases and/or cancer.
Asbestos-containing material may only be machined by specialists.
−Wherever possible, use a dust extractor suitable for the material you are working
on (e.g. a special BAIER dust extractor).
−Ensure the workplace is properly ventilated.
−We recommend wearing a face mask respirator with filter class P2 or P3
(to EN 149:2001).
Observe the relevant regulations in your country for the materials to be machined.
Do not use the power tool near flammable materials.
Sparks could ignite these materials.
Avoid causing situations where other people can stumble or trip.
Tripping over cables can cause serious injuries.
Electrical safety
Check the power tool, connection cable and plug for damage before each use.
A damaged machine is dangerous and no longer safety to operate.
Note the mains voltage! The power source voltage must match the details
given on the rating plate of the power tool.
If using the power tool with a mobile generators, loss of power or atypical be-
haviour on switching on is possible.
Do not use the power tool if the cable is damaged. Do not touch the damaged
cable and disconnect the mains plug if the cable is damaged while you are
working.
Damaged cables increase the risk of an electric shock.
Only use extension cables, which are suitable for the machine's power con-
sumption and have a minimum cross-section of 1.5 mm2. If you use a cable
drum, always completely unwind the cable.
The rolled up cable can heat up and start to burn.
Regularly clean the ventilation slots of your power tool by blowing it out.
Never use liquids. Never insert screwdrivers or any other objects into the ven-
tilation slits. Do not cover the ventilation slits.
The motor fan draws dust into the housing and a large accumulation of metal dust
can cause electrical hazards.
External electromagnetic interference (e.g. mains voltage fluctuations, elec-
trostatic discharges) can cause the power tool to switch off automatically.
In this case, switch off the power tool and then switch it back on again.
Do not use any insert tools which require liquid coolant.
The use of water or other liquid coolants could result in an electric shock.

Safety of people
Wear personal protective equipment and, depending on the work situation,
use:
full-face protection, eye protection or safety glasses/goggles,
hard hat and special apron
Protect yourself against debris thrown up by wearing a hard hat, safety
goggles or face protection and wear an apron, if necessary.
Hearing protection
The typical A-weighted sound pressure level of this power tool is over
85 dB (A) while working with the tool.
If you are exposed to loud noise for lengthy periods, there is a risk of
hearing damage or even hearing loss.
Dust mask, half-face filter mask or face mask respirator
Inhaling fine mineral dust can cause health damage. We recommend
wearing a face mask respirator with filter class P2 or P3
(to EN 149:2001).
The machine may only be used together with an approved dust extrac-
tor (e.g. a special BAIER dust extractor).
Anti-vibration safety gloves
At a release value A (8) for arm-hand vibrations of over 2.5 m/s2, the
wearing of anti-vibration safety gloves is recommended.
Vibrations can cause health damage.
Non-slip safety footwear
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.
Hold the tool at the insulated gripping surfaces only when carrying out work
during which the insert tool can hit concealed electricity cables or the tool's
own mains power lead.
Contact with a live conductor can also energise metal parts of the tool and cause an
electric shock.
Keep the mains power lead away from rotating insert tools.
If you lose control of the tool, the mains power lead can be cut or caught and your
hand or arm can be pulled into the rotating tool.

9
For your Safety
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.
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.
If the machine is switched on, do not direct insert tools towards your own or
other people's bodies. Do not touch or take hold of the tools.
Hazards when using and handling the power tool
The power tool may only be used with the guard plate fitted.
Do not use insert tools or accessories. which have not been especially pro-
vided and recommended for this power tool by the manufacturer.
Just because you can attach the insert tools and/or accessories to your power tool
is not a guarantee of safe use.
The allowable speed of the insert tool must be at least as high as the maxi-
mum speed given on the power tool.
Accessories which rotate faster than approved can break and fly off the tool.
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.
Insert tools, installation materials and accessories must precisely match the
spindle of your power tool.
Insert tools and accessories, which do not precisely fit on the spindle of the power
tool rotate irregularly, vibrate severely and can result in loss of control.
Change insert tools carefully and only use the mounting tools provided, if
they are in perfect condition. Disconnect the mains plug before changing the
insert tool.
Use of the mounting tool provided prevents damage to the power tool and insert
tool.
After attaching insert tools, before switching on, check that they are correctly
fitted and can freely rotate. Ensure that insert tools do not touch the protec-
tive hood or other parts.
Never use damaged insert tools. Before each use, check insert tools for splin-
ters and cracks. If the power tool or insert tool is dropped or falls, check
whether it is damaged, or use an undamaged insert tool. If you have checked
and inserted the insert tool, keep yourself and other people nearby outside
the plane of the rotating insert tool and let the power tool run at maximum
speed for one minute.
Most damaged insert tools break during this test period.

10
For your Safety
Do not expose power tools to extreme heat and cold.
Mechanical and electrical damage can occur during extreme heat and/or cold.
Allow the insert tools, tool holders and other parts cool in the immediate vi-
cinity of the work area after use.
The machines can be very hot after use, do not touch the parts, risk of injuries.
Additional signs or other, non BAIER-specific parts may not be screwed or
riveted onto the motor, handle, gearbox or protective housing.
This could damage the power tool and cause malfunctions.
Avoid unnecessary noise emissions.
Note and follow the safety and work instructions for the accessories used.
Kickback and relevant safety instructions
Kickback is the sudden reaction caused by a rotating insert tool that get caught or is
blocked. Catching or blocking results in abrupt stopping of the rotating insert tool.
This causes the power tool to be accelerated in an uncontrolled way, opposite the
rotational direction of the insert tool at the blocking point.
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.
When switching on and while working with the power tool, hold onto it tightly
at both handles and place your body and arms in a position in which they can
absorb the kickback forces or reaction torque on starting up.
The person using the tool can control the kickback and reaction forces by taking
suitable precautions.
Avoid blocking of the insert tools caused by pressing too hard or feeding too
fast.
Overloading increases the possibility of kickback or breaking the insert tools.
Never place your hand near rotating insert tools.
The insert tool can move across your hand during kickback.
Keep your body clear of the area in which the power tool would move in the
event of kickback.
The kickback drives the power tool in the opposite direction to the movement of the
insert tool at the blocking point.
Take particular care when working in the area of corners, sharp edges, etc.
Prevent insert tools from rebounding from or jamming in the workpiece.
The rotating insert tool tends to get stuck in corners, sharp edges or if it rebounds.
This causes loss of control or kickback.
