workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
16. 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 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.
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 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 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 operator from
broken wheel fragments and accidental contact with
wheel.
c) 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.
d) 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.
e) 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
