f) Threaded mounting of accessories must match the grin-
der spindle thread. For accessories mounted by anges, the
arbour hole of the accessory must t the locating diameter
of the ange. Accessories that do not match the mounting hard-
ware 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 shop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of

stopping ying debris generated by various operations. The dust
mask or respirator must be capable of ltrating 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 protec-
tive equipment. Fragments of workpiece or of a broken accessory
may y away and cause injury beyond immediate area of operation.
j) Hold the 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 could give the operator an electric shock.
k) 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 wheel.
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 ammable 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 snag-
ging 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
English

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 opera-
ting procedures or conditions and can be avoided by taking proper
precautions as given below.
a) Maintain a rm 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 Speci c for Grinding and Abrasive Cutting-
O Operations:
a) Use only wheel types that are recommended for your
power tool and the speci c 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 the operator from broken wheel fragments, accidental
contact with wheel and sparks that could ignite clothing.
c) Wheels must be used only for recommended applications.
For example: do not grind with the side of cut-o wheel. Abra-
sive cut-o wheels are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
d) Always use undamaged wheel anges that are of correct
size and shape for your selected wheel. Proper wheel anges
support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-o wheels may be di erent from grinding wheel
anges.
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.
Additional Safety Warnings Speci c for Abrasive Cutting-O
Operations:
a) Do not "jam" the cut-o 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 o the power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-o 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.
