GENERAL POWER TOOLS WARNING
may fly away and cause injury beyond
immediate area of operation.
j) Hold 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 shock
the operator.
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.
KICKBACK 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.
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.
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.
Safety warnings for grinding and cutting:
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. Wheel intended
for larger power tool is not suitable
for the higher speed of a smaller tool
and may burst.
