a conversion may result in a loss of control and cause serious personal
injury
d) Do not use accessories which are not specifically designed and
specified by the tool manufacturer. Just because the accessory can
be attached to your power tool, it does not assure safe operation.
e) 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.
f) 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.
g) The dimensions of the accessory mounting must fit the
dimensions of the mounting hardware of the power tool.
Accessories that do not match the mounting hardware of the power tool
will run out of balance, vibrate excessively and may cause loss of
control.
h) 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.
i) 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.
j) 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.
k) Hold the 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 could give the operator an
electric shock.
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
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 uncon-
trolled 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 work-
piece, 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 precauti-
ons as given below.

a) Maintain a firm grip with both hands on the power tool and
position your body and arms 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, segmented
diamond wheel with a peripheral gap greater than 10 mm 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 specified 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 grinding surface of the centre depressed wheels must be
mounted below the plane of the guard lip. An improperly mounted
wheel that projects through the plane of the guard lip cannot be
adequately protected.
c) 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 the
operator from broken wheel fragments, accidental contact with wheel
and sparks that could ignite clothing.
d) Wheels must be used only for specified 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.
e) 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.
f) 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.
g) When using dual purpose wheels always use the correct guard
for the application being performed. Failure to use the correct guard
may not provide the desired level of guarding, which could lead to
serious injury.
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
