Safety Warnings Specifi C For Grinding And Abrasive Cutting-Off Operations - DeWalt DWE4887 Manual De Instrucciones

b) 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.
c) Do not attach a toothed saw blade. Such blades create
frequent kickback and loss of control.
d) Always feed the bit into the material in the same
direction as the cutting edge is exiting from the material
(which is the same direction as the chips are thrown).
Feeding the tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and pull the tool in the
direction of this feed.
e) When using rotary files, cut-off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if they
become slightly canted in the groove, and can kickback. When
a cut-off wheel grabs, the wheel itself usually breaks. When a
rotary file, high-speed cutter or tungsten carbide cutter grabs,
it may jump from the groove and you could lose control of the
tool.
Safety Warnings Specifi c for Grinding and
Abrasive Cutting-Off Operations
a) Use only wheel types that are recommended for your
power tool and only for recommended applications. For
example: do not grind with the side of a cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding,
side forces applied to these wheels may cause them to shatter.
b) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved shoulder
flange that are of correct size and length. Proper mandrels
will reduce the possibility of breakage.
c) 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 snagging of the wheel in the cut and
the possibility of kickback or wheel breakage.
d) Do not position your hand in line with and behind the
rotating wheel. When the wheel, at the point of operation,
is moving away from your hand, the possible kickback may
propel the spinning wheel and the power tool directly at you.
e) When wheel is pinched, snagged 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.
f) 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.
g) 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.
h) 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.
