f
Never lay the power tool down until the acces-
sory has come to a complete stop.
The spinning
accessory may grab the surface and pull the power
tool out of your control.
f
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.
f
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.
f
Do not operate the power tool near flamma-
ble materials.
Sparks could ignite these materials.
f
Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may
result in electrocution or shock.
Kickback and related warnings
f
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 condi-
tions.
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.
f
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 kick-
back forces, if proper precautions are taken.
f
Never place your hand near the rotating
accessory.
The accessory may kickback over your
hand.
f
Do not position your body in the area where
the power tool will move if kickback occurs.
Kickback will propel the tool in the direction oppo-
site to the wheel’s movement at the point of snag-
ging.
f
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.
f
Do not attach a saw chain woodcarving blade
or toothed saw blade.
Such blades create fre-
quent kickback and loss of control over the power
tool.
Additional safety instructions for grinding and
cutting off operations
f
Always use guard designed for the type of
wheel you are using. The guard must be
securely attached to the power tool and posi-
tioned 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.
f
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.
f
Wheels must be used only for recommended
applications.
For example: do not grind with the
side of the cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding; side forces
applied to these wheels may cause them to shatter.
f
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.
Wheels intended for larger power
tools are not suitable for the higher speed of a
smaller tool and may burst.
Additional safety warnings specific for abrasive
cutting off operations
f
Do not “jam” the cut-off wheel or apply exces-
sive 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.
f
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 spin-
ning wheel and the power tool directly at you.
