Kickback Causes And Related Warnings - Milwaukee M18 FUEL 2736-20 Manual Del Operador

Kickback causes and related warnings

Kickback is a sudden reaction of the workpiece due
to a pinched, jammed saw blade or misaligned line of
cut in the workpiece with respect to the saw blade or
when a part of the workpiece binds between the saw
blade and the rip fence or other fixed object. Most
frequently during kickback, the workpiece is lifted from
the table by the rear portion of the saw blade and is
propelled towards 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.
• Never stand directly in line with the saw blade.
Always position your body on the same side of
the saw blade as the fence. Kickback may propel
the workpiece at high velocity towards anyone
standing in front and in line with the saw blade.
• Never reach over or in back of the saw blade
to pull or to support the workpiece. Accidental
contact with the saw blade may occur or kickback
may drag your fingers into the saw blade.
• Never hold and press the workpiece that is being
cut off against the rotating saw blade. Pressing
the workpiece being cut off against the saw blade
will create a binding condition and kickback.
• Align the fence to be parallel with the saw blade.
A misaligned fence will pinch the workpiece against
the saw blade and create kickback.
• Use a featherboard to guide the workpiece against
the table and fence when making non-through
cuts such as rabbeting, dadoing or resawing
cuts. A featherboard helps to control the workpiece
in the event of a kickback.
• Use extra caution when making a cut into blind
areas of assembled workpieces. The protruding
saw blade may cut objects that can cause kickback.
• Support large panels to minimise the risk of saw
blade pinching and kickback. Large panels tend
to sag under their own weight. Support(s) must be
placed under all portions of the panel overhanging
the table top.
• Use extra caution when cutting a workpiece that
is twisted, knotted, warped or does not have a
straight edge to guide it with a mitre gauge or
along the fence. A warped, knotted, or twisted
workpiece is unstable and causes misalignment of
the kerf with the saw blade, binding and kickback.
• Never cut more than one workpiece, stacked
vertically or horizontally. The saw blade could
pick up one or more pieces and cause kickback.
• When restarting the saw with the saw blade in
the workpiece, centre the saw blade in the kerf so
that the saw teeth are not engaged in the material.
If the saw blade binds, it may lift up the workpiece
and cause kickback when the saw is restarted.
• Keep saw blades clean, sharp, and with sufficient
set. Never use warped saw blades or saw blades
with cracked or broken teeth. Sharp and properly set
saw blades minimise binding, stalling and kickback.
Table saw operating procedure warnings
• Turn off the table saw and disconnect the power
cord when removing the table insert, changing
the saw blade or making adjustments to the
riving knife, antikickback device or saw blade
guard, and when the machine is left unattended.
Precautionary measures will avoid accidents.
• Never leave the table saw running unattended.
Turn it off and don't leave the tool until it comes
to a complete stop. An unattended running saw is
an uncontrolled hazard.
• Locate the table saw in a well-lit and level area
where you can maintain good footing and balance.
It should be installed in an area that provides
enough room to easily handle the size of your
workpiece. Cramped, dark areas, and uneven
slippery floors invite accidents.
• Frequently clean and remove sawdust from
under the saw table and/or the dust collection
device. Accumulated sawdust is combustible and
may self-ignite.
• The table saw must be secured. A table saw that
is not properly secured may move or tip over.
• Remove tools, wood scraps, etc. from the table
before the table saw is turned on. Distraction or
a potential jam can be dangerous.
• Always use saw blades with correct size and
shape (diamond versus round) of arbour holes.
Saw blades that do not match the mounting hardware
of the saw will run off-centre, causing loss of control.
• Never use damaged or incorrect saw blade
mounting means such as flanges, saw blade
washers, bolts or nuts. These mounting means were
specially designed for your saw, for safe operation
and optimum performance.
• Never stand on the table saw, do not use it as
a stepping stool. Serious injury could occur if the
tool is tipped or if the cutting tool is accidentally
contacted.
• Make sure that the saw blade is installed to rotate
in the proper direction. Do not use grinding
wheels, wire brushes, or abrasive wheels on a
table saw. Improper saw blade installation or use of
accessories not recommended may cause serious
injury.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
• Some dust created by power sanding,
WARNING
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
