n) 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.
o) 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.
p) Do not operate the power tool near
flammable materials. Sparks could
ignite these materials.
q) Do not use accessories that require
liquid coolants. Using water or other
liquid coolants may result in electrocution
or shock.
Further safety instructions for all
operations--Kickback and Related
Warnings
Kickback is a sudden reaction to a pinched
or snagged rotating wheel, backing pad, 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 the auxiliary handle 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. The 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 instructions for grinding
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
operator from broken wheel fragments
and accidental contact with wheel.
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 grinding wheel flanges.
e) Do not use worn down wheels from larger
power tools. A wheel intended for a larger
power tool is not suitable for the higher speed
of a smaller tool and may burst.
