General Power Tool Safety Warnings
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 refrig-
erators. 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) pro-
tected 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 con-
trolled 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, break-
age 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 acci-
dentally 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 tempera-
ture above 40 °C may cause explosion. may exhibit unpredictable behaviour resulting in fire, explosion or
risk of injury.

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.
Specific Safety Warnings For Angle Grinders
DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to
grinder safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.
Always use proper guard with grinding wheel. A guard protects operator from broken wheel frag-
ments.
Do not use accessories which are not specifically designed and recommended by the tool manu-
facturer. Just because the accessory can be attached to your power tool, it does not assure safe opera-
tion.
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.
The arbor size of wheels, flanges, backing pads or any other accessory must properly fit the spin-
dle of the power tool. Accessories with arbor holes that 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 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 shock the operator.

5
Never lay the power tool down until the accessory has come to a complete stop. The spinning acces-
sory 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 accesso-
ry 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.
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
kickout. 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.
Maintain a firm grip on the power tool and position your body and arm to allow you to resist kick-
back 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 precau-
tions 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 acces-
sory. 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.
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 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 operator from
broken wheel
fragments and accidental contact with wheel.

6
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 suit-
able for the higher speed of a smaller tool and may burst.
Safety Warnings Specific for Sanding Operations
Do not use excessively oversized sanding disc paper. Follow manufacturer’s recommendations, when
selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration
hazard and may cause snagging, tearing of the disc or kickback.
Safety Warnings Specific for Wire Brushing Operations:
Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not over stress
the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing
and/or skin.
If the use of a guard is recommended for wire brushing, do not allow any interference of the wire
wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrif-
ugal forces.
Safety Warnings Specific for Polishing Operations
Do not allow any loose portion of the polishing bonnet or its attachment strings to spin freely. Tuck away
or trim any loose attachment strings. Loose and spinning attachment strings can entangle your fingers
or snag on the workpiece.
Additional Safety Warnings
GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance
your personal safety.
Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments.
Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power
tool.
Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and may lead to loss of control.
Check damaged parts. Before further use of the power tool, a guard or other part that is damaged
should be
carefully checked to determine that it will operate properly and perform its intended function. Check
for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other
conditions that may affect its operation. A guard or other part that is damaged should be properly
repaired or replaced by an authorized service center. Following this rule will reduce the risk of shock,
fire, or serious injury.
Inspect for and remove all nails from lumber before using this power tool. Following this rule will
reduce the risk of serious personal injury.
