FURTHER SAFETY INSTRUCTIONS
FOR ALL OPERATIONS
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 SPECIFIC
FOR GRINDING AND ABRASIVE
CUTTING-OFF 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 are unsafe.
• The grinding surface of center
depressed wheels must 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.
• 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.
• 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
anges support the wheel thus reducing
the possibility of wheel breakage.
Flanges for cut-off wheels may be
different from grinding wheel anges.
• 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
• 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
