• NEVER CUT FERROUS METALS (those with any iron or steel content), CEMENT
BOARD OR MASONRY. Certain man-made materials have special instructions for
cutting on table saws. Follow the manufacturer's recommendations at all times.
Damage to the saw and personal injury may result.
• THE PROPER THROAT PLATE MUST BE IN PLACE AT ALL TIMES to reduce the
risk of a thrown work piece and possible injury.
• USE THE CORRECT SAW BLADE FOR THE INTENDED OPERATION. The blade
must rotate toward the front of the saw. Always tighten the blade arbor nut securely.
Before use, inspect the blade for cracks or missing teeth. Do not use a damaged
blade.
• NEVER ATTEMPT TO FREE A STALLED SAW BLADE WITHOUT FIRST TURNING
THE MACHINE OFF AND DISCONNECTING THE SAW FROM THE POWER
SOURCE. If a work piece or cut-off piece becomes trapped inside the guard, turn saw
off and wait for blade to stop before lifting the guard and removing the piece.
• NEVER START THE MACHINE with the work piece against the blade to reduce the risk
of a thrown work piece and personal injury.
• NEVER run the work piece between the fence and a molding cutterhead to reduce the
risk of a thrown work piece and personal injury.
• NEVER have any part of your body in line with the path of the saw blade. Personal
injury will occur.
• NEVER PERFORM LAYOUT, ASSEMBLY OR SET-UP WORK on the table/work area
when the machine is running. A sudden slip could cause a hand to move into the blade.
Severe injury can result.
• CLEAN THE TABLE/WORK AREA BEFORE LEAVING THE MACHINE. Lock
the switch in the "OFF" position and disconnect from the power source to prevent
unauthorized use.
• DO NOT leave a long board (or other work piece) unsupported so the spring of
the board causes it to shift on the table resulting in loss of control and possible
injury. Provide proper support for the work piece, based on its size and the type of
operation to be performed. Hold the work firmly against the fence and down against the
table surface.
• DO NOT OPERATE THIS MACHINE until it is completely assembled and installed
according to the instructions. A machine incorrectly assembled can cause serious
injury.
• OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are
not thoroughly familiar with the operation of this machine. Knowledge is safety.
• ADDITIONAL INFORMATION regarding the safe and proper operation of power
tools (i.e., a safety video) is available from the Power Tool Institute, 1300 Sumner
Avenue, Cleveland, OH 44115-2851 (www.powertoolinstitute.com). Information is also
available from the National Safety Council, 1121 Spring Lake Drive, Itasca, IL 60143-
3201. Please refer to the American National Standards Institute ANSI 01.1 Safety
Requirements for Woodworking Machines and the U.S. Department of Labor OSHA
1910.213 Regulations.
TERMS: THE FOLLOWING TERMS WILL BE USED THROUGHOUT THE MANUAL
AND YOU SHOULD BECOME FAMILIAR WITH THEM.
• Through-sawing refers to any cut that completely severs the work piece.
• Push Stick refers to a wooden stick, usually homemade, that is used to push small
work piece 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 work
piece back toward 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 work piece other than the operator's hand.
SAW BLADE GUARD AND SPLITTER
Your table saw is equipped with a blade guard and splitter assembly that covers the blade
and prevents accidental contact. The splitter is a flat plate that fits into the cut made by the
saw blade and effectively fights kickback by lessening the tendency of the blade to bind
in the cut. The splitter can only be used when making through cuts that sever the wood.
When making rabbets and other cuts that make less than through cuts, the blade guard
and splitter assembly must be removed from the saw. 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 lock it if it tries to move backwards toward the operator.
MAKING A PUSH STICK (Inside Back Cover)
• In order to operate your table saw safely you must use a push stick whenever the size
or shape of the work piece 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.
• No special wood is needed to make additional push-sticks as long as it's sturdy and
long enough. A length of 12" (305 mm) is recommended with a notch that fits against
the edge of the work piece to prevent slipping. It's a good idea to have several push
sticks of the same length [12" (305 mm)] with different size notches for different work
piece thicknesses.
• See the inside back cover for a picture of a push stick. The shape can vary to suit your
own needs as long as it performs its intended function of keeping your hands away from
the blade.
KICKBACKS
How to Avoid Them and Protect Yourself from Possible Injury
a. Be certain that the rip fence is parallel to the saw blade.
b. Do not rip by applying the feed force to the section of the work piece 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 short work, 6" (152 mm) wide or less. For
less than 2" (51 mm) wide, you must use a special fixture.
c. Keep saw blade guard, splitter and anti-kickback teeth in place and operating properly.
Keep teeth sharp. If teeth are not operational, return your unit to the nearest authorized
D WALT service center for repair. The splitter must be in alignment with the saw blade
E
and the teeth must stop a kickback once it has started. Check their action before ripping
by pushing the wood under the anti-kickback teeth. The teeth must prevent the wood
from being pulled toward the front of the saw.
d. Plastic and composition (like hardboard) materials may be cut on your saw. However,
since these are usually quite hard and slippery, the anti-kickback pawls may not stop
a kickback. Therefore, be especially attentive to following proper set up and cutting
procedures for ripping.
e. Use saw blade guard and splitter for every operation for which it can be used, including
all through-sawing.
f. Push the work piece past the saw blade prior to release.
g. NEVER rip a work piece that is twisted or warped, or does not have a straight edge to
guide along the fence.
h. Use featherboards when the anti-kickback device or the guard and splitter cannot be
used.
i. NEVER saw a large work piece that cannot be controlled.
j. NEVER use the fence as a guide or length stop when crosscutting.
k. NEVER saw a work piece with loose knots, flaws, nails or other foreign objects.
l. NEVER rip a work piece shorter than 10".

construction activities contains chemicals known to the State of California to cause cancer,
