GENERAL SAFETY RULES
WARNING!
Read all instructions. Failure to follow all instructions
listed below may result in electric shock, fire and/or
serious injury. The term “power tool” in all of the warnings listed below refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
Do not operate power tools in explosive atmo-
spheres, 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.
Use battery only with charger listed. For use with
18 V nickel-cadmium and 18 V lithium-ion battery
packs, see tool/appliance/battery pack/charger correla-
tion supplement 987000-432.
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 safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools
with your finger on the switch or plugging in 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
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry, 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 these devices can
reduce dust-related hazards.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
power tool in unexpected situations.
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.
Maintain power tools. Check for misalignment or bind-
ing 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 main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
2 — English
GENERAL SAFETY RULES
Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking
into account the working conditions and the work to
be performed. Use of the power tool for operations dif-
ferent from those intended could result in a hazardous
situation.
BATTERY TOOL USE AND CARE
Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack into
power tools that have the switch on invites accidents.
Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type

tery packs. Use of any other battery packs may create
a risk of injury and fire.
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.
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.
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.
WARNING!
To reduce the risk of injury, user must read instruction
manual.
When servicing a power tool, use only identical
replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized
parts or failure to follow Maintenance instructions may
create a risk of shock or injury.
SPECIFIC SAFETY RULES
SAFETY WARNINGS COMMON FOR GRINDING,
SANDING AND POLISHING OPERATIONS
This power tool is intended to function as a grinder,
sander, or polisher. 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 wire brushing 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, it 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.
The arbor size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle 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.
3 — English
SPECIFIC SAFETY RULES
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. Cutting
accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and shock the
operator.
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.
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.
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.
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.
Wheels must be used only for recommended
applications. For example: do not grind with the side
of an abrasive 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.
Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels and
other accessories running over rated speed can fly apart
and cause injury.

OPERATIONS
Do not use excessively oversized sanding disc
paper. Follow manufacturers 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 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.
