refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk
of electric shock.
d) 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.
e) 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.
f) 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.
3) Personal safety
a) 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.
b) 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.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
f) 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.
g) 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.
4) Power tool use and care
a) 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.
b) 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.
c) 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.

d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) 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.
5) Battery tool use and care
a) 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.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) 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.
d) 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.
6) Service

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.
b) Operations such as sanding, wire brushing and polishing are not recommended to be performed
with this power tool. Operations for which the power tool was not designed may create a hazard and
cause personal injury.
2.2.2 SAFETY INSTRUCTIONS FOR ALL OPERATIONS
Safety Warnings Common for Grinding, Sanding, Wire Brushing, Polishing or Abrasive Cutting-Off
Operations:
a) This power tool is intended to function as a grinder and cut-off tool. Read all safety warnings,
This will ensure that the safety of the power tool is maintained.

c) Do not use accessories which are not specifically designed and recommended by the tool
manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe
operation.
d) The rated speed of the accessory must be at least equal to the maximum speed marked on the
power tool. Accessories running faster than their rated speed can break and fly apart.
e) The outside diameter and the thickness of your accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
f) Threaded mounting of accessories must match the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the accessory must fit the locating diameter of the flange.
Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
g) Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels
for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked
wires. If power tool or accessory is dropped, inspect for damage or install an undamaged
accessory. After inspecting and installing an accessory, position yourself and bystanders away
from the plane of the rotating accessory and run the power tool at maximum no-load speed for one
minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of
stopping flying debris generated by various operations . The dust mask or respirator must be capable of
filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause
hearing loss.
i) Keep bystanders a safe distance away from work area. Anyone entering the work area must wear
personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
j) Hold the power tool by insulated gripping surfaces only, when performing an operation where the
cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
k) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning accessory.
l) Never lay the power tool down until the accessory has come to a complete stop. The spinning
accessory may grab the surface and pull the power tool out of your control.
m) Do not run the power tool while carrying it at your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the accessory into your body.
n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in
electrocution or shock.
2.2.3 FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is
entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out.

The wheel may either jump toward or away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist
kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or
torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper
precautions are taken.
b) Never place your hand near the rotating accessory. Accessory may kickback over your hand.
c) Do not position your body in the area where power tool will move if kickback occurs. Kickback will
propel the tool in direction opposite to the wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause
loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent
kickback and loss of control.
2.2.4 ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING AND CUTTING-OFF OPERATIONS
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations:
a) Use only wheel types that are recommended for your power tool and the specific guard designed
for the selected wheel. Wheels for which the power tool was not designed cannot be adequately
guarded and are unsafe.
b) The grinding surface of centre depressed wheels must be mounted below the plane of the guard
lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately
protected.
c) The guard must be securely attached to the power tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the operator. The guard helps to protect the operator from
broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
d) Wheels must be used only for recommended applications. For example: do not grind with the side
of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
e) Always use undamaged wheel flanges that are of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel flanges.
f) Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may burst.
2.2.5 ADDITIONAL SAFETY INSTRUCTIONS FOR CUTTING-OFF OPERATIONS
Additional Safety Warnings Specific for Abrasive Cutting-Off Operations:
a) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the
wheel in the cut and the possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible kickback may propel the spinning wheel and the
power tool directly at you.
c) When wheel is binding or when interrupting a cut for any reason, switch off the power tool and
hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove
the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur.

Investigate and take corrective action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully
re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a “pocket cut” into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.

3.2 AFETY INSTRUCTIONS
3.2.1 GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings, instructions, illustrations and specifications provided with
this power tool. Failure to follow all 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.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk
of electric shock.
d) 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.
e) 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.
f) 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.
3) Personal safety
a) 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.
b) 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.

c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
f) 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.
g) 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.
h) 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.
4) Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) 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.
h) 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.
5) Battery tool use and care
a) 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.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) 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.
d) 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.
e) 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.

f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130 °C may cause explosion.
NOTE The temperature „130 °C“ can be replaced by the temperature „265 °F“.
g) Follow all charging instructions and do not charge the battery pack or tool outside the
temperature range specified in the instructions. Charging improperly or at temperatures outside the
specified range may damage the battery and increase the risk of fire.
6) Service
a) 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.
b) Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
3.2.2 DRILL SAFETY WARNINGS
−Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
−Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the operator an electric shock.
3.2.3 SAFETY INSTRUCTIONS WHEN USING LONG DRILL BITS
a) Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the
bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
b) Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in
personal injury.
c) Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend
causing breakage or loss of control, resulting in personal injury.
3.2.4 SAFETY INSTRUCTIONS FOR BATTERIES AND CHARGER
Batteries
Never attempt to open for any reason.
Do not store in locations where the temperature may exceed 40°C (104°F).
Charge only at ambient temperatures between 4°C and 40°C(39.2°F and 104°F).
Charge only using the charger provided with the tool.
Store your batteries in a cool dry place (5°C-20°C/41°F-68°F). Never store batteries in discharged
state.
It is better for Li-ion batteries to discharge and reload them regularly (at least 4 times a year). The
ideal charge for long-term storage of your Li-ion battery is 40% of capacity.
When disposing of batteries, follow the instructions given in the section “Protecting the
environment”.
Do not cause short circuits. If connection is made between the positive (+) and negative (-) terminal
directly or via accidental contact with metallic objects, the battery is short circuited and an intense
current will flow causing heat generation which may lead to casing rupture or fire.
Do not heat. If batteries are heated to above 100°C (212°F), sealing and insulating separators and
other polymer components may be damaged resulting in electrolyte leakage and/or internal short
