Batteries And Chargers; Important Safety Instructions For All Battery Packs - DeWalt DCS7485 Manual De Instrucciones

Terms: The following terms will be used throughout the manual
and you should become familiar with them.
• Thru-sawing refers to any cut that completely cuts through the workpiece.
• Non thru-sawing refers to any cut that does not completely cut through the workpiece.
• Push Stick refers to a wooden or plastic stick, usually homemade, that is used to push small
workpiece through the saw and keeps the operator's hands clear of the blade.
• Kickback occurs when the saw blade binds in the cut and violently thrusts the workpiece back
toward the operator. Even more serious and dangerous kickback will result from using the saw
without the guard or riving knife. Material that contacts the outer rim of the blade will be thrown
violently and unpredictably at the operator.
• Freehand refers to cutting without the use of a miter gauge or rip fence or any other means of
guiding or holding the workpiece other than the operator's hands.

WARNING: Never perform freehand cutting with this saw.
Plunge cutting refers to cutting where the workpiece is either lowered down onto the blade with
•
the workpiece controlled by the user's hands or the workpiece is supported by the user's hands on
the table surface and the blade is then raised up through the workpiece.

WARNING: Never perform plunge cutting with this saw.
• Resawing - Flipping material to make a cut the saw is not capable of making in one pass.

WARNING: Do not perform resaw cuts on this saw.
• Outfeed - The distance behind the saw required to pass the material all the way through the cut.
• Dado cutting - Using a dado head or other type of shaping cutter head to cut dadoes or
decorative grooves.

WARNING: Do not install dado head or shaping head cutters on this saw.
Saw Blade Guard Assembly, Anti-kickback Assembly and
Riving Knife
This table saw is equipped with a blade guard assembly with splitter and anti-kickback assembly that
covers the blade and reduces the possibility of accidental blade contact. A riving knife is also provided
for use when making non-thru cuts. The riving knife and splitter are flat plates that are positioned
behind the saw blade and fit into the cut made by the saw blade. Two anti-kickback pawls are
located on the sides of the splitter that allow the wood to pass through the blade in the cutting
direction but reduce the possibility of the material being thrown backwards toward the operator.
They help prevent kickbacks caused by binding or pinching of the cut material at the back of the
saw blade. The blade guard assembly and anti-kickback assembly can only be used when
making thru-cuts that sever the wood. When making rabbets, dadoes, tenons, lap joints
or other non-thru cuts, the blade guard assembly and anti-kickback assembly must be
removed and the riving knife must be installed.
Use all components of the guarding system (blade guard assembly, riving knife and anti-kickback
assembly) for every operation for which they can be used including all thru-cutting. If you elect not
to use any of these components for a particular application exercise additional caution regarding
control of the workpiece, the use of push sticks, the position of your hands relative to the blade, the
use of safety glasses, the means to avoid kickback and all other warnings contained in this manual
and on the saw itself. Replace the guarding systems as soon as you return to thru-cutting
operations. Keep the guard assembly in working order.
Making a Push Stick (Inside Back Cover)
• In order to operate this table saw safely you must use a push stick whenever the size or shape of
the workpiece would cause your hands to be within 6" (152 mm) of the saw blade or other cutter.
A push stick is included with this saw.
• You may need additional push sticks to accommodate materials of different thicknesses. Plans
for making push sticks are included in the back of this instruction manual. Push sticks should
be made from solid wood, plywood, plastic or other strong but soft material. A length of 15.7"
(400 mm) is recommended with a notch that fits against the edge of the workpiece to prevent
slipping. It's a good idea to have several push sticks of the same length (15.7" [400 mm] with
different size notches for different workpiece thicknesses.
Kickbacks
Kickbacks can cause serious injury. A kickback occurs when a part of the workpiece binds between
the saw blade and the rip fence, or other fixed object, and rises from the table and is thrown toward
the operator. Kickbacks can be avoided by attention to the following conditions.
How to Avoid Them and Protect Yourself from Possible Injury
a ) Use the blade guard with splitter, or use the riving knife whenever possible.
b ) Be certain that the rip fence is parallel to the saw blade.
c ) Do not rip by applying the feed force to the section of the workpiece that will
become the cut-off (free) piece. Feed force when ripping should always be applied
between the saw blade and the fence; use a push stick for narrow work, 6" (152 mm) wide
or less.
d ) Keep saw blade guard assembly, riving knife and anti-kickback assembly in place
and operating properly. If anti-kickback assembly is not operational, return your unit to
the nearest authorized D WALT service center for repair. The splitter and riving knife must be
e
in alignment with the saw blade and the anti-kickback assembly must stop a kickback once
it has started. Check their action before ripping by pushing the wood under the anti-kickback
assembly. The teeth must prevent the wood from being pulled toward the front of the saw.
e ) Plastic and composite (like laminate flooring) materials may be cut on this saw.
These materials may have hard or slippery surfaces which limit the effectiveness of the anti-
kickback assembly. When cutting these materials, pay particular attention to the instructions
for ripping.
f ) Use saw blade guard assembly, anti-kickback assembly and riving knife for every
operation for which it can be used, including all thru-sawing.
g ) Push the workpiece past the saw blade prior to release.
h ) NEVER rip a workpiece that is twisted or warped, or does not have a straight edge to
guide along the fence.
i ) NEVER saw a large workpiece that cannot be controlled.
j ) NEVER use the fence as a guide or length stop when crosscutting.
k ) NEVER saw a workpiece with loose knots, flaws, nails or other foreign objects.
l ) NEVER rip a workpiece shorter than 10" (254 mm).
m ) NEVER use a dull blade – replace or have resharpened.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also
use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY
EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California to cause cancer,
birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• 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.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles away from face and body.
NOTICE: Under certain conditions of use, such as extended operation in low-humidity
conditions, or cutting certain materials such as vinyl trim, static charges may build up on
the metal portions of the saw. Touching the metal parts will discharge this static build up
and may result in a short, mild, but harmless electrical shock. However, if you are concerned
about this, you may bring the saw into a D
that there is no electrical malfunction of the saw.
