Safety Warnings Specifi C For Grinding And Abrasive Cutting-Off Operations; Safety Warnings Specifi C For Wire Brushing Operations - DeWalt DC411 Manual De Instrucciones

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 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 Specifi c 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
40
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 Specifi c
for Abrasive Cutting-Off Operation
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 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.
Safety Warnings Specifi c for Wire
Brushing Operations
a) Be aware that wire bristles are thrown by
the brush even during ordinary operation.
