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 exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use 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 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 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 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.

sander, wire brush, or polisher. Read all safety warnings, instructions, illustrations and specifications
provided with this power tool. Failure to follow all in-
structions listed below may result in electric shock, fire
and/or serious injury.
Operations such as 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 acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
The arbour size of wheels, flanges, backing pads or
any other accessory must properly fit the spindle of
the power tool. Accessories with arbour 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 in-
spect 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
When servicing a power tool, use only identical replace-
ment parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to

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
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 ²live² wire may make
exposed metal parts of the power tool ²live² and shock
the operator.
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

fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
3 - English
SPECIFIC SAFETY RULES
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 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.
SAFETY WARNINGS SPECIFIC FOR
SANDING 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.
SAFETY WARNINGS SPECIFIC FOR WIRE
BRUSH OPERATIONS
Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress 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 centrifugal
forces.
ADDITIONAL SAFETY RULES
Always use proper guard with grinding wheel. A guard
protects operator from broken wheel fragments.
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations, as well
as the specific potential hazards related to this tool.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
Always wear eye protection with side shields marked
to comply with ANSI Z87.1. Failure to do so could
result in objects being thrown into your eyes, resulting in
possible serious injury.
4 - English

operation is dusty. Following this rule will reduce the risk
of serious personal injury.
Protect your hearing. Wear hearing protectors during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
Inspect tool cords periodically and, if damaged, have
repaired at your nearest authorized service center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
Check damaged parts. Before further use of the
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.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need
to be grounded.
WARNING:
The double insulated system is intended to protect
the user from shock resulting from a break in the tool’s
internal insulation. Observe all normal safety precautions
to avoid electrical shock.
NOTE: Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should be
performed only by a qualified service technician. For service,
we suggest you return the tool to your nearest authorized
service center for repair. Always use original factory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should be
connected to a power supply that is 120 volts, AC only
(normal household current), 60 Hz. Do not operate this tool
on direct current (DC). A substantial voltage drop will cause
a loss of power and the motor will overheat. If the tool does
not operate when plugged into an outlet, double-check the
power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An
undersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a tool, use an extension cord
that is designed for outside use. This type of cord is designated with “W-A” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

been designed for use only with the guard installed.
Attempting to use grinder with guard removed will result
in loose particles being thrown against the operator
resulting in serious personal injury.
GRINDING AND SANDING
See Figure 6, page 13.
Always carefully select and use grinding wheels that are
recommended for the material to be ground. Make sure
that the minimum operating speed of any accessory wheel
selected is not less than 11,000 RPM. The grinding wheel
provided with the angle grinder is suitable for grinding welds,
preparing surfaces to be welded, grinding structural steel,
and grinding stainless steel.
To operate the grinder:
Secure all work before beginning any operation. Secure
small workpieces in a vise or clamp to a workbench.
Hold the angle grinder in front and away from you with
both hands, keeping the grinding wheel clear of the
workpiece.
Start the angle grinder and let the motor and grinding
wheel build up to full speed.
Gradually lower angle grinder until the grinding wheel
contacts the workpiece.
Keep the angle grinder tilted at an angle from 5° and 15°.
WARNING:
To prevent loss of control and possible serious personal
injury, always operate the grinder with both hands, keeping one hand on the side handle.
Move the angle grinder continuously at a steady, consis-
tent pace.
NOTICE:
If the grinder is held in one spot too long, it will gouge
and cut grooves in the workpiece. If the grinder is held
at too sharp an angle, it will also gouge the workpiece
because of concentration of pressure on a small area.
Use just enough pressure to keep the angle grinder from
chattering or bouncing.
NOTE: Heavy pressure will decrease the grinder’s speed
and put a strain on the motor. Normally the weight of the
tool alone is adequate for most grinding jobs. Use light
pressure when grinding jagged edges or loose bolts where
there is the potential for the grinder to snag on the metal
edge.
Lift the angle grinder away from the workpiece before
turning the angle grinder off.

GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spackling
compounds, or plaster are subject to accelerated wear and
possible premature failure because the fiberglass chips and
grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this
tool for extended work on these types of materials. However,
if you do work with any of these materials, it is extremely
