Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of the
workpiece or of a broken accessory may fly away and
cause injury beyond the immediate area of operation.
Position the compressed air hose clear of the
spinning accessory. If you lose control over the tool,
the compressed air hose may be cut or snagged and
your hand or arm may be pulled into the spinning ac-
cessory.
Never lay the air tool down until the accessory
has come to a complete stop. The spinning acces-
sory may grab the surface and pull the air tool out of
your control.
Do not run the air tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing or your hair, pulling the ac-
cessory into your body.
Do not operate the air tool near flammable mate-
rials. Sparks could ignite these materials.
Further safety instructions for all
operations
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel, backing pad, brush, or any other accessory. Pinch-
ing or snagging causes rapid stalling of the rotating accessory,
which in turn causes the uncontrolled air tool to be forced in
the direction opposite to 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 the direction
of the wheel's movement at the point of pinching. Abrasive
wheels may also break under these conditions.
Kickback is the result of air tool misuse and/or incorrect oper-
ating procedures or conditions and can be avoided by taking
proper precautions as given below.
Maintain a firm grip on the air tool and position
your body and arm to allow you to resist kick-
back forces. Always use the 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 acces-
sory. The accessory may kick back over your hand.
Do not position your body in the area where the
air tool will move if kickback occurs. Kickback will
propel the tool in the 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 ac-
cessory. 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 specific for grinding
and abrasive cutting off operations
Always use a guard designed for the type of
wheel you are using. The guard must be securely
attached to the air tool and positioned for maxi-
mum safety, so the least amount of wheel is ex-
posed toward the operator. Check routinely that
the guard is in proper condition and is securely
attached to the air tool. The guard helps to protect
operator from broken wheel fragments and accidental
contact with the wheel.
Use only wheel types that are recommended for
your air tool and the specific guard designed for
the selected wheel. Wheels for which theair tool
was not designed cannot be adequately guarded and
are unsafe.
Wheels must be used only for recommended ap-
plications. For example: do not grind with the
side of a 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 air
tools. A wheel intended for a larger air tool is not suit-
able for the higher speed of a smaller tool and may
burst.
