Kickback And Related Warnings - Craftsman CMEG200 Manual De Instructiones

English
o ) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
p ) Do not use Type 11 (flaring cup) wheels on this
tool. Using inappropriate accessories can result
in injury.
q ) Always use auxiliary handle. Tighten the handle
securely. The auxiliary handle should always be used
to maintain control of the tool at all times.
r ) When starting the tool with a new or
replacement wheel, or a new or replacement
wire brush installed, hold the tool in a well
protected area and let it run for one minute. If
the wheel has an undetected crack or flaw, it
should burst in less than one minute. If the wire
brush has loose wires, they will be detected.
Never start the tool with a person in line with the
wheel. This includes the operator.
s ) To prevent the spindle end from contacting the
bottom of the hole of the abrasive product, use
accessories that have a threaded hole depth of
at least 21 mm. Failure to use an accessory with the
appropriate thread depth could result in damage to
the abrasive product and injury to the operator or
persons in the area.
t ) The arbor size of hubbed wheels, flanges,
backing pads or any other accessory must
properly fit the spindle of the power tool.
Accessories with arbor holes that do not match the
mounting hardware of the power tool will run out
of balance, vibrate excessively and may cause loss
of control.
u ) Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand against your body leaves it
unstable and may lead to loss of control.

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 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
4
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
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 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.
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.
Safety Warnings Specific for Sanding
Operations
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturers 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.
