English

• 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 hand.

WARNING: Never perform freehand cutting with this saw.

• Plunge cutting refers to blind cuts in the workpiece made by either raising the blade

through the workpiece or lowering the workpiece down to the blade.

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: Resawing IS NOT recommended.

SAW BLADE GUARD ASSEMBLY, ANTI-KICKBACK ASSEMBLY AND RIVING KNIFE

Your table saw is equipped with a blade guard assembly, anti-kickback assembly and riving

knife that covers the blade and reduces the possibility of accidental blade contact. The riving

knife 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 blade guard assembly and anti-

kickback assembly can only be used when making through cuts that sever the wood.

When making rabbets and other cuts that make non through cuts, the blade guard

assembly and anti-kickback assembly must be removed and riving knife lowered to

the non through cut position marked on the riving knife. Two anti-kickback pawls are

located on the sides of the riving knife 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.

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 through

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 your 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.

• No special wood is needed to make additional push-sticks as long as it’s sturdy and long

enough. 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.

• 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

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. 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 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.

c. 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

EWALT service center for repair. The riving knife must be 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.

d. Plastic and composite (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 assembly, anti-kickback assembly and riving knife for every

operation for which it can be used, including all through-sawing.

f. Push the workpiece past the saw blade prior to release.

g. NEVER rip a workpiece that is twisted or warped, or does not have a straight edge to

guide along the fence.

h. NEVER saw a large workpiece that cannot be controlled.

i. NEVER use the fence as a guide or length stop when crosscutting.

j. NEVER saw a workpiece with loose knots, flaws, nails or other foreign objects.

k. NEVER rip a workpiece shorter than 10" (254mm).

l. NEVER use a dull blade – replace or have resharpened.

WARNING: Some dust created by power sanding, 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 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 disburse 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. Always operate tool in well-ventilated area and provide for proper dust removal. Use

dust collection system wherever possible.
