AIR VENTS OFTEN COVER MOVING PARTS AND SHOULD BE AVOIDED
Loose clothes, jewelry or long hair can be caught in moving parts.

AN EXTENSION CORD MUST HAVE ADEQUATE WIRE SIZE (AWG OR AMERICAN WIRE GAUGE) FOR SAFETY
The smaller the gauge number of the wire, the greater the capacity of the cable, that is, 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

ENVIRONMENT & MATERIALS HANDLING
CUTTING PLASTICS, SAP COATED WOOD, AND OTHER MATERIALS MAY CAUSE MELTED MATERIAL TO ACCUMULATE ON THE BLADE TIPS AND THE BODY OF THE SAW BLADE INCREASING THE RISK OF BLADE OVERHEATING AND BINDING WHILE CUTTING
If cutting plastic materials, avoid melting the plastic.
NEVER CUT METALS, 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 LOCKED IN PLACE AT ALL TIMES TO REDUCE THE RISK OF A THROWN WORKPIECE AND POSSIBLE INJURY
AVOID OVERHEATING THE SAW BLADE TIPS
Keep material moving and parallel with the fence. Do not force work into the blade.
DO NOT LEAVE A LONG BOARD (OR OTHER WORKPIECE) 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 workpiece, 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.
NEVER ATTEMPT TO CUT A STACK OF LOOSE PIECES OF MATERIAL WHICH COULD CAUSE LOSS OF CONTROL OR KICKBACK
Support all materials securely.
ACCESSORIES SELECTION, USE & MAINTENANCE
DO NOT INSTALL A DIAMOND* MASONRY BLADE AND ATTEMPT TO USE THE TABLE SAW AS A WET SAW
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 or dull blade.
NEVER ATTEMPT TO FREE A STALLED SAW BLADE WITHOUT FIRST TURNING THE MACHINE OFF AND DISCONNECT THE PLUG FROM THE POWER SOURCE
If a workpiece or cut-off piece becomes trapped inside the blade guard assembly, turn saw off and wait for blade to stop before lifting the blade guard assembly and removing the piece.
DO NOT USE SAW BLADES THAT DO NOT CONFORM TO THE DIMENSIONS STATED IN THE SPECIFICATIONS
Do not use any spacers to make a blade fit onto the spindle. Use only the blades specified in this manual, complying with EN847-1, if intended for wood and similar materials.
CONSIDER APPLYING SPECIALLY DESIGNED NOISE-REDUCTION BLADES

Updated 04/2024 | For educational purposes only. Copyright ©2024 DEWALT. The yellow/black color scheme is a trademark for DEWALT power tools, accessories, anchors, and concrete adhesives. Always follow the guidance in the instruction manual.

DO NOT USE HIGH STEEL (HS) SAW BLADES, CRACKED OR DAMAGED SAW BLADES AND ENSURE THAT THE CHOSEN SAW BLADE IS SUITABLE FOR THE MATERIAL TO BE CUT
ALWAYS USE BLADES WITH CORRECT SIZE AND SHAPE OF ARBOR HOLES (DIAMOND VS. ROUND)
Blades that do not match the mounting hardware of the saw will run off-center, causing loss of control.
BODY POSITIONING
AVOID AWKWARD POSITIONS, WHERE A SUDDEN SLIP COULD CAUSE A HAND TO MOVE INTO A SAW BLADE
NEVER REACH IN BACK OF, OR AROUND, THE CUTTING TOOL WITH EITHER HAND TO HOLD DOWN THE WORKPIECE OR RETRIEVE MATERIALS
Never reach around or over saw blade while the blade is spinning.
DO NOT REACH UNDERNEATH THE WORKPIECE
The guard cannot protect you from the blade below the workpiece.
KEEP ARMS, HANDS AND FINGERS AWAY FROM THE BLADE TO PREVENT SERIOUS INJURY
Keep your second hand on auxiliary handle or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
DO NOT HAVE ANY PART OF YOUR BODY IN LINE WITH THE BLADE
Personal injury may occur. Stand to either side of the blade.
NEVER PERFORM LAYOUT, ASSEMBLY OR SET-UP WORK ON THE TABLE/WORK AREA WHEN THE MACHINE IS RUNNING
Never perform any adjustments while the saw is running such as fence repositioning or removal, bevel lock adjustment, or blade height adjustment. A sudden slip could cause a hand to move into the blade. Severe injury can result.
NEVER HOLD THE WORKPIECE IN YOUR HANDS OR ACROSS YOUR LEG WHILE CUTTING
Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
HOLD THE POWER TOOL BY INSULATED GRIPPING SURFACES, WHEN PERFORMING AN OPERATION WHERE THE CUTTING TOOL MAY CONTACT HIDDEN WIRING
Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock
GUARDING-RELATED WARNING
KEEP GUARDS IN PLACE
Guards must be in working order and be properly mounted. A guard that is loose, damaged, or is not functioning correctly must be repaired/replaced.
ALWAYS USE SAW BLADE GUARD, RIVING KNIFE AND ANTI-KICKBACK PAWLS FOR EVERY THROUGH-CUTTING OPERATION
For through-cutting operations where the saw blade cuts completely through the thickness of the workpiece, the guard and other safety devices help reduce the risk of injury.
IMMEDIATELY REATTACH THE GUARDING SYSTEM AFTER COMPLETING AN OPERATION
(such as rabbeting cuts) which requires removal of the guard, riving knife and/or anti kickback device. These devices help to reduce the risk of injury.
MAKE SURE THE SAW BLADE IS NOT CONTACTING THE GUARD, RIVING KNIFE OR THE WORKPIECE BEFORE THE SWITCH IS TURNED ON
Inadvertent contact of these items with the saw blade could cause a hazardous condition.
ADJUST THE RIVING KNIFE AS DESCRIBED IN THIS INSTRUCTION MANUAL
Incorrect spacing, positioning and alignment can make it ineffective in reducing the likelihood of kickback.
FOR THE RIVING KNIFE AND ANTI-KICKBACK PAWLS TO WORK, THEY MUST BE ENGAGED IN THE WORKPIECE
These devices are ineffective when cutting workpieces that are too short to with them. Under these conditions a kickback cannot be prevented by the riving knife and anti-kickback pawls.
USE THE APPROPRIATE SAW BLADE FOR THE RIVING KNIFE
For the riving knife to function properly, the saw blade diameter must match the appropriate riving knife and the body of the saw blade must be thinner than the thickness of the riving knife and the cutting width of the saw blade must be wider than the thickness of the riving knife.
CUTTING PROCEDURE WARNINGS
DO NOT PERFORM ANY OPERATION “FREEHAND”
Always use the rip fence or the miter gauge to position and guide the workpiece. “Freehand” means using your hands to support or guide the workpiece in lieu of a rip fence or miter gauge. Freehand sawing leads to misalignment, binding and kickback.
ADJUST THE CUTTING DEPTH TO THE THICKNESS OF THE WORKPIECE
Less than a full tooth of the blade teeth should be visible below the workpiece.
FEED THE WORKPIECE INTO THE SAW BLADE OR CUTTER ONLY AGAINST THE DIRECTION OF ROTATION
Feeding the workpiece in the same direction that the saw blade is rotating above the table may result in the workpiece, and your hand, being pulled into the saw blade.
FEED WORKPIECE AT AN EVEN PACE
Do not bend or twist the workpiece. If jamming occurs, turn the tool off immediately, unplug the tool then clear the jam. Jamming the saw blade by the workpiece can cause kickback or stall the motor.
USE HOLD-DOWNS, JIGS, FIXTURES OR FEATHER BOARDS TO HELP GUIDE AND CONTROL THE WORKPIECE
Accessories for use with your tool are available at extra cost from your local dealer or authorized service center. Instructions for making a push stick, a narrow rip auxiliary fence, a push block and feather boards are included in this manual.
NEVER USE THE MITER GAUGE TO FEED THE WORKPIECE WHEN RIPPING AND DO NOT USE THE RIP FENCE AS A LENGTH STOP WHEN CROSS CUTTING WITH THE MITER GAUGE
Guiding the workpiece with the rip fence and the miter gauge at the same time increases the likelihood of saw blade binding and kickback.
USE ONLY THE PUSH STICK PROVIDED BY THE MANUFACTURER OR CONSTRUCTED IN ACCORDANCE WITH THE INSTRUCTIONS AND IS APPROPRIATE TO THE APPLICATION
A push stick is a wooden or plastic stick, often homemade, that should be used whenever the size or shape of the workpiece would cause you to place your hands within 6″ (152 mm) of the blade. Never use a damaged or cut push stick because it may break causing your hand to slip into the saw blade.
WHEN RIPPING, ALWAYS APPLY THE WORKPIECE FEEDING FORCE BETWEEN THE FENCE AND THE SAW BLADE
Use a push stick when the distance between the fence and the saw blade is less than 5.9″ (150 mm) and use a push block when this distance is less than 2″ (50 mm). “Work helping” devices keep your hand a safe distance from the saw blade.
PROVIDE AUXILIARY WORKPIECE SUPPORT TO THE REAR AND/OR SIDES OF THE SAW TABLE FOR LONG AND/OR WIDE WORKPIECES TO KEEP THEM LEVEL
A long and/or wide workpiece may pivot on the table’s edge, causing loss of control, saw blade binding and kickback.
USE AN AUXILIARY FENCE IN CONTACT WITH THE TABLETOP WHEN RIPPING WORKPIECES LESS THAN (2 MM) THICK
A thin workpiece may wedge under the rip fence and create a kickback.
