DeWalt D23550 Traducido De Las Instrucciones Originales página 33

the motor reaction drives the unit rapidly back
toward the operator;
– If the blade becomes twisted or misaligned
in the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and
jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be
avoided by taking proper precautions as given
below:
a) Maintain a firm grip with both hands on
the saw and position your arms to resist
kickback forces. Position your body to
either side of the blade, but not in line with
the blade. Kickback could cause the saw to
jump backwards, but kickback forces can be
controlled by the operator, if proper precautions
are taken.
b) When blade is binding, or when interrupting
a cut for any reason, release the trigger and
hold the saw motionless in the material until
the blade comes to a complete stop. Never
attempt to remove the saw from the work
or pull the saw backward while the blade is
in motion or kickback may occur. Investigate
and take corrective actions to eliminate the
cause of blade binding.
c) When restarting a saw in the work piece,
centre the saw blade in the kerf and check
that saw teeth are not engaged into the
material. If saw blade is binding, it may walk up
or kickback from the work piece as the saw is
restarted.
d) Support large panels to minimise the risk of
blade pinching and kickback. Large panels
tend to sag under their own weight. Supports
must be placed under the panel on both sides,
near the line of cut and near the edge of the
panel.
e) Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
f) Blade depth and bevel adjusting locking
levers must be tight and secure before
making cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.
g) The D23550, D23650 has no plunge cutting
function!
Safety Instructions for Saws with a
Pendulum Blade Guard
a) Check lower guard for proper closing
before each use. Do not operate the saw if
lower guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position. If saw is accidentally
dropped, lower guard may be bent. Raise
the lower guard with the retracting handle
and make sure it moves freely and does
not touch the blade or any other part, in all
angles and depths of cut.
b) Check the operation of the lower guard
spring. If the guard and the spring are not
operating properly, they must be serviced
before use. Lower guard may operate
sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
c) Lower guard should be retracted manually
only for special cuts such as "plunge
cuts" and "compound cuts". Raise lower
guard by retracting handle and as soon as
blade enters the material, the lower guard
must be released. For all other sawing, the
lower guard should operate automatically.
d) Always observe that the lower guard is
covering the blade before placing saw
down on bench or floor. An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to
stop after switch is released.
Additional Safety Instructions for All
Saws with Riving Knife
a) Use the appropriate riving knife for the
blade being used. For the riving knife to
work, it must be thicker than the body of the
blade but thinner than the tooth set of the
blade.
b) Adjust the riving knife as described in
this instruction manual. Incorrect spacing,
positioning and alignment can make the riving
knife ineffective in preventing kickback.
c) Always use the riving knife except when
plunge cutting. Riving knife must be
replaced after plunge cutting. Riving knife
causes interference during plunge cutting
and can create kickback.
d) For the riving knife to work, it must be
engaged in the workpiece. The riving knife
is ineffective in preventing kickback during
short cuts.
e) Do not operate the saw if riving knife is
bent. Even a light interference can slow the
closing rate of a guard.
