English
• 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.
• Operations such as grinding, sanding, wire
brushing, polishing or cutting-off are not recom-
mended to be performed with this power tool. Op-
erations for which the power tool was not designed
may create a hazard and cause personal injury�
• Do not use accessories which are not spe-
cifically 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 rat-
ed 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 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 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, in-
spect for damage or install an undamaged acces-
sory. 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 ca-
pable of stopping small abrasive or workpiece frag-
ments. 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 sur-
faces 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 accesso-
ry. 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 acces-
sory has come to a complete stop. The spinning ac-
cessory 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 acces-
sory 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 cool-
ants.
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 direc-
tion 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 in-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below�
• Maintain a firm grip on the power tool and po-
sition 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 ac-
cessory. Accessory may kickback over your hand�
• Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back 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 ac-
cessory.
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 guidelines during power tool
operation
• Do not allow any loose portion of the polishing bon-
net or its attachment strings to spin freely� Tuck away
or trim any loose attachment strings� Loose and spin-
ning attachment strings can entangle your fingers or
snag on the workpiece�
The power tool is designed for polishing
only, never use the power tool as an angle
grinder.
