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.
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 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, clothing and
gloves 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 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.
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. 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) 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.
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, sander, wire brush, polisher or
cut-off 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.
b) Operations such as grinding, 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.
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) 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.
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 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. NOTE The above warning may be omitted if polishing is the only
recommended operation
k) Position the cord clear of the spinning accessory. If you lose control, the cord maybe 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.
KICKBACK AND RELATED WARNINGS
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.
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) 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.
c) 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.
d) 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.

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.
SAFETY WARNINGS SPECIFIC FOR SANDING OPERATIONS:
a) 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 POLISHING OPERATIONS:
a) 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 BRUSHING OPERATIONS:
a) 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.
b) 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.
It is recommended that the power tool is always supplied via a residual current device with a
rated current of 30mA or less.
Wear hearing protection while operating the power tool.
Wear eye protection while operating the power tool.
Use a dust mask or respirator for applications which generate dust.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
Intended Use:
This rotary tool is intended for DIY use only, for light drilling, grniding, sanding and polishing, as well
as for engraving, cutting and wire brushing on most metals, glass, wood and ceramics.
