equal to the maximum speed marked on the power tool.
Accessories running faster than their rated speed can
break and fly apart.
i) 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) The arbour size of wheels, flanges, backing pads
or any other accessory must properly fit the spindle of
the power tool. Accessories with arbour 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.
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 noload 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 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 power tool by insulated gripping surfaces, 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. 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
4
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.
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.
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
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.
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.
Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control over the power tool.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
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.
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, accidental
contact with wheel and sparks that could ignite clothing.
Wheels must be used only for recommended
applications. For example: do not grind with the side of
the cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding; side forces applied to these wheels
may cause them to shatter.
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.
Do not use worn down wheels from larger power tools.
Wheels intended for larger power tools are not suitable for
the higher speed of a smaller tool and may burst.
Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
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.
Do not position your body in line with and behind the
rotating wheel. When the wheel, at the point of operation,
