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 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 reaction 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 Grinding and Abrasive
Cutting-Off 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 grinding surface of center depressed wheels
must not be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the plane
of the guard lip cannot be adequately protected.
c ) 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 the operator from broken wheel
fragments, accidental contact with wheel and sparks that
could ignite clothing.
d ) 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.
e ) 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.
f ) 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.

Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations
a ) Do not "jam" the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth
of cut. Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut and
the possibility of kickback or wheel breakage.
b ) Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power tool
directly at you.
c ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to
a complete stop. Never attempt to remove the cut-
off wheel from the cut while the wheel is in motion
otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and carefully
reenter the cut. The wheel may bind, walk up or kickback if
the power tool is restarted in the workpiece.
e ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback. Large
workpieces tend to sag under their own weight. Supports
must be placed under the workpiece near the line of cut and
near the edge of the workpiece on both sides of the wheel.
f ) Use extra caution when making a "pocket cut" into
existing walls or other blind areas. The protruding wheel
may cut gas or water pipes, electrical wiring or objects that
can cause kickback.
Safety Warnings Specific for Sanding Operations
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturer's 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 Wire Brushing
Operations
a ) Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress the
wires by applying excessive load to the brush. The wire
bristles can easily penetrate light clothing and/or skin.
b ) Guard must be used for wire brushing, do not allow
any interference of the wire wheel or brush with the
guard. Wire wheel or brush may expand in diameter due to
work and centrifugal forces.
c ) Safety goggles or safety glasses with side shields
and a full face shield compliant with ANSI Z87.1 MUST
be worn by the operator and others that are within 50'
(15.2 m) of the use of this product.
Additional Safety Information

WARNING: Never modify the power tool or any part of it.
Damage or personal injury could result.

WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or dust
mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
