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. Incorrect-
ly 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 ap-
plication, 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 workpi-
ece 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 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 accessory.
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. Ac-
cidental 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
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 workpi-
ece, 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, de-
pending 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 precau-
tions 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 kick-
back 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 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 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.
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.
