Safety Warnings Specific For Grinding And Abrasive Cutting-Off Operations - KRESS KUS10P Manual De Instrucciones

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 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.
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 operator from broken
wheel fragments and accidental contact with
wheel and sparks that could ignite clothing.
d) 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.
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.

INSTRUCTIONS
FOR CUTTING-OFF
OPERATIONS
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 re-enter the cut. The wheel
may bind, walk up or kickback if the power tool is
restarted in the workpiece.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
f) Use extra caution when making a "pocket
cut" into existing walls or other blind
areas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can
cause kickback.
