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.
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 Sanding Operations:
a)
Do not use excessively oversized sanding disc paper. Follow
manufacturers recommendations, when selecting sanding paper.
Larger sanding paper extending beyond the sanding pad presents
a laceration hazard and may cause snagging, tearing of the disc or
kickback.
Safety Warnings Specific for Polishing Operations:
a)
Do not allow any loose portion of the polishing bonnet or its
attachment strings to spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning attachment strings can
entangle your fingers or snag on the work piece.
entering the work area must wear personal protective equipment.
Fragments of work piece or of a broken accessory 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.
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 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 work
piece, the edge of the wheel that is entering into the pinch point can dig
