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.
 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.
Safety warnings speci fi c for grinding 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 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 and 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 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.
Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may
burst.

DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
