personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
j.
Hold the 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 could give the operator an
electric shock.
Position the cord clear of the spinning accessory.
k.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
accessory.
Never lay the power tool down until the accessory
l.
has come to a complete stop. The spinning accessory
may grab the surface and pull the power tool out of
your control.
Do not run the power tool while carrying it at your
m.
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body.
Regularly clean the power tool's air vents. The
n.
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal may
cause electrical hazards.
Do not operate the power tool near flammable
o.
materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
p.
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.
Maintain a firm grip on the power tool and position
a.
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.
b.
Accessory may kickback over your hand.
Do not position your body in the area where power
c.
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
d.
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
e.
toothed saw blade. Such blades create frequent
kickback and loss of control.
Safety Warnings Specific for Grinding:
Use only wheel types that are recommended for your
a.
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 centre 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
c.
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 and
sparks that could ignite clothing.
Wheels must be used only for recommended
d.
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
e.
