tool. Operations for which the power
tool was not designed may create a
hazard and cause personal injury.
b) 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.
c) 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.
d) 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.
e) 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.
f) Do not use a damaged accessory.
Before each use inspect the
accessory such as abrasive wheel
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.
g) Wear personal protective
equipment. Depending on
application, use face shield, safety
goggles or safety glasses. As
appropriate, wear dust mask,
hearing protectors, gloves and
work shop 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.
h) 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.
i) Hold power tool by insulated
gripping surfaces only, when
performing an operation where the
accessory may contact hidden
wiring or its own cord. Accessory
contacting a "live" wire may make
exposed metal parts of the power
tool "live" and shock the operator.
j) 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.
k) 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.
l) 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.
m)Regularly clean the power toolʼs
air vents. The motorʼs fan will draw
the dust inside the housing and
excessive accumulation of powdered
metal may cause electrical hazards.
n) Do not operate the power tool near
flammable materials. Sparks could
ignite these materials.
o) Do not use accessories that
require liquid coolants. Using water
or other liquid coolants may result in
electrocution or shock.
p) Do not use Type 11 (flaring cup)
wheels on this tool. Using inappropriate
accessories can result in injury.
q) Always use side handle. Tighten
the handle securely. The side
handle should always be used to
maintain control of the tool at all times.
R) Use clamps or another practical
way to secure and support the
work piece to a stable platform.
Holding the work by hand or against
your body leaves it unstable and may
lead to loss of control.

operations
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
accessoryʼs 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 wheelʼs movement
at the point of pinching. Abrasive
wheels may also break under these
conditions.
Kickback is the result of tool misuse
and/or incorrect operating procedures
or conditions and can be avoided by
taking proper precautions as given
below:
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 reaction
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 wheelʼs 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
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) 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.
c) Wheels must be used only for
recommended applications. For
example: do not grind with the
side of wheel. Abrasive wheels are
intended for peripheral grinding, side
forces applied to these wheels may
cause them to shatter.
d) 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.
e) 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
a) 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 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
