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. Threaded mounting of accessories must match the grinder
spindle thread. For accessories mounted by flanges, the arbour
hole of the accessory must fit the locating diameter of the
flange. 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.
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 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 the power tool by insulated gripping surfaces only,
when performing an operation where the cutting tool may
contact hidden wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and could give the
operator an electric shock.
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 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.
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.
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 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 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 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. 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-off wheel. Abrasive
cut-off 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
