GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions. Failure
to follow the warnings and instructions 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.
■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 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, clothing and gloves 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.
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
the battery pack 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.
■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.

2
■Maintain power tools. 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.
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.
ANGLE GRINDER SAFETY WARNINGS
SAFETY WARNINGS COMMON FOR GRINDING
OPERATIONS:
■This power tool is intended to function as a grinder
tool. 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.
■Operations such as sanding, wire brushing,
polishing or cutting-off 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.
■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 does not assure safe
operation.
■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.
■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.
■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 to do not match the mounting hardware of the
power tool will run out of balance, vibrate excessively
and may cause loss of control.
■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.
■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.
■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.
■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.
■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.
■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.
■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.
■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.
■Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
■Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.
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

3
causing the wheel to climb out or kick out. The wheel may
either jump toward or away from the operator, depending
on the 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.
■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.
■Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
■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.
■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.
■Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
ADDITIONAL SAFETY INSTRUCTIONS FOR GRINDING
OPERATIONS
Safety warnings specific for grinding operations:
■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.
■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.
■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.
■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.
■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.
■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.

RESIDUAL RISKS
Even when the angle grinder is used as prescribed, it is
still impossible to completely eliminate certain residual risk
factors. The following hazards may arise and the operator
should pay special attention to avoid the following:
■Injury caused by thrown-off particles
–Metal or abrasive particles may enter the eyes and
cause severe permanent damage. Wear goggles
approved for grinding operations whenever you use
the product.
■Injury caused by vibration
–Limit exposure. See Risk Reduction.
■Injury caused by dust
–Wear appropriate dust control mask with filters
suitable for protecting against particles from the
material being worked on and abrasive particles
from the grinding disc. Do not eat, drink, or smoke
in the work area. Ensure adequate ventilation.
■Injury from contact with the grinding disc
–The disc and workpiece will become hot during
use. Wear gloves when changing discs or touching
workpiece. Keep hands away from the grinding
area at all times. Clamp the workpiece whenever
possible.
■Injury caused by noise
–Prolonged exposure to noise will increase the risk
of hearing damage, and the effects are cumulative.
When using power tools for any extended period of
time, wear hearing protection.
RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking, and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■Keep your body warm in cold weather. When operating
the product, wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.
WARNING
Injuries may be caused or aggravated by prolonged use
of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
STARTUP PROTECTION
Machines with a lock-on switch are fitted with a cut-out.
This prevents the machine from restarting by itself after a
power failure. When resuming work, switch the machine off
and then switch it back on again.

VIBRATION LEVEL
WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of
exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used
for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may
significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working
period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation of work patterns.
