SAVE THESE INSTRUCTIONS

General Safety Rules

WARNING: Read all instructions before operating product. Failure to follow all

instructions listed below may result in electric shock, fire and/or serious injury.

SAVE THESE INSTRUCTIONS

WARNING: FOLLOW ALL WIRING CODES and recommended electrical connections

to prevent shock or electrocution.

Grounding Instructions

If saw is of grounded construction, read the following instructions.

DANGER: SHOCK HAZARD. THIS MACHINE MUST BE GROUNDED WHILE IN USE.

SERIOUS INJURY COULD RESULT.

ALL GROUNDED, CORD-CONNECTED MACHINES

In the event of a malfunction or breakdown, grounding provides a path of least resis-

tance for electric current to reduce the risk of electric shock. This machine is equipped

with an electric cord having an equipment-grounding conductor and a grounding plug.

The plug must be plugged into a matching outlet that is properly installed and grounded

in accordance with all local codes and ordinances. Do not modify the plug provided - if

it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper

connection of the equipment-grounding conductor can result in risk of electric shock.

The conductor with insulation having an outer surface that is green with or without yel-

low stripes is the equipment-grounding conductor. If repair or replacement of the electric

cord or plug is necessary, do not connect the equipment-grounding conductor to a live

terminal. Check with a qualified electrician or service personnel if the grounding instruc-

tions are not completely understood, or if in doubt as to whether the machine is properly

grounded. Use only three-wire extension cords that have three-prong grounding type

plugs and matching three-conductor receptacles that accept the machine’s plug, as

shown in Fig. A. Repair or replace damaged or worn cord immediately.

GROUNDED, CORD-CONNECTED MACHINES INTENDED FOR USE ON A SUPPLY

CIRCUIT HAVING A NOMINAL RATING LESS THAN 150 VOLTS

If the machine is intended for use on a circuit that has an outlet that looks like the one

illustrated in Fig. A, the machine will have a grounding plug that looks like the plug illus-

trated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig. B,

may be used to connect this plug to a matching two-conductor receptacle as shown in

Fig. B if a properly grounded outlet is not available. The temporary adapter should be

used only until a properly grounded outlet can be installed by a qualified electrician. The

green-colored rigid ear, lug, and the like, extending from the adapter must be connected

to a permanent ground such as a properly grounded outlet box. Whenever the adapter

is used, it must be held in place with a metal screw.

DANGER: IN ALL CASES, MAKE CERTAIN THAT THE RECEPTACLE IN QUESTION IS

PROPERLY GROUNDED. IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN

CHECK THE RECEPTACLE.

Double Insulation

If saw is of double-insulated construction, read the following instructions.

Double insulated tools are constructed throughout with two separate

layers of electrical insulation or one double thickness of insulation between

you and the tool’s electrical system. Tools built with this insulation system

are not intended to be grounded. As a result, your tool is equipped with a

two prong plug which permits you to use extension cords without concern

for maintaining a ground connection. Repair or replace damaged or worn

cord immediately

NOTE: Double insulation does not take the place of normal safety precautions when oper-

ating this tool. The insulation system is for added protection against injury resulting from a

possible electrical insulation failure within the tool.

POLARIZED PLUGS

To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider

than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit

fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to

install the proper outlet. Do not change the plug in any way.

Important Safety Instructions

• TO REDUCE THE RISK OF KICKBACK AND OTHER INJURIES, KEEP GUARDS IN

PLACE and in working order at all times.

• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that

keys and adjusting wrenches are removed from spindle before turning tool on. Tools,

scrap pieces, and other debris can be thrown at high speed, causing injury.

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

• DO NOT USE THE MACHINE IN A DANGEROUS ENVIRONMENT. The use of power

tools in damp or wet locations or in rain can cause shock or electrocution. Keep your

work area well-lit to avoid tripping or placing arms, hands, and fingers in danger.

• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.

Your shop is a potentially dangerous environment.

• MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing

starter keys. The unauthorized start-up of a machine by a child or visitor may result in

injury.

• DO NOT FORCE TOOL. It will do the job better and be safer at the rate for which it was

designed.

• USE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not

designed. Using the incorrect tool or attachment may result in personal injury.

• USE PROPER EXTENSION CORD. Make sure your extension cord is in good condi-

tion. If your product is equipped with a cord set, use only three-wire extension cords

that have three-prong grounding-type plugs and three-pole receptacles that accept the

tool’s plug. When using an extension cord, be sure to use one heavy enough to carry

the current your product will draw. An undersized cord will cause a drop in line voltage

resulting in loss of power and overheating. 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 smaller the gauge number, the heavier the cord.

• WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or

other jewelry to get caught in moving parts. Non-slip footwear is recommended. Wear

protective hair covering to contain long hair. Air vents may cover moving parts and

should also be avoided.

• 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.

• DO NOT OVERREACH. Keep proper footing and balance at all times. Loss of balance

may cause personal injury.

• MAINTAIN TOOLS WITH CARE. Keep blades sharp and clean for best and safest

performance. Follow instructions for lubricating and changing accessories. Poorly

maintained blades and machines can further damage the blade or machine and/or

cause injury.

• TURN THE MACHINE “OFF”, AND DISCONNECT THE MACHINE FROM THE

POWER SOURCE before installing or removing accessories, before adjusting or

changing set-ups, when making repairs or changing locations. Do not touch the plug’s

metal prongs when unplugging or plugging in the cord. An accidental start-up can cause

injury.

• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure that the switch is

in the “OFF” position before plugging in the power cord. In the event of a power failure,

move the switch to the “OFF” position. An accidental start-up can cause injury.

• USE RECOMMENDED ACCESSORIES. Use only accessories that are recommended

by the manufacturer for your model. Accessories that may be suitable for one tool may

be hazardous when used on another tool. Consult the instruction manual for recom-

mended accessories. The use of improper accessories may cause risk of injury to

persons.

• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cut-

ting tool is unintentionally contacted.

• CHECK FOR DAMAGED PARTS. Before further use of the tool, a guard or other part

that is damaged should be carefully checked to determine that it will operate properly

and perform its intended function—check for alignment of moving parts, binding of

moving parts, breakage of parts, mounting and any other conditions that may affect

its operation. A guard or other part that is damaged should be properly repaired or

replaced. Do not use tool if switch does not turn it on and off. Damaged parts can cause

further damage to the machine and/or personal injury.

• DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation

of the blade or cutter only.

• NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave

tool until it comes to a complete stop. Serious injury can result.

• DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN

GASEOUS OR EXPLOSIVE ATMOSPHERES. Motors and switches in these tools may

spark and ignite fumes.

• STAY ALERT, WATCH WHAT YOU ARE DOING, AND USE COMMON SENSE. DO

NOT USE THE MACHINE WHEN YOU ARE TIRED OR UNDER THE INFLUENCE

OF DRUGS, ALCOHOL, OR MEDICATION. A moment of inattention while operating

power tools may result in serious injury.

• DO NOT ALLOW FAMILIARITY (gained from frequent use of your saw) TO

REPLACE SAFETY RULES. Always remember that a careless fraction of a second is

sufficient to inflict severe injury.

Additional Safety Rules for Table Saws

WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety

glasses. Also use face or dust mask if cutting operation is dusty. All users and bystanders

MUST 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.

• 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 work piece.

• KEEP ARMS, HANDS AND FINGERS AWAY from the blade to prevent serious injury.

• USE A PUSH STICK OR PUSH BLOCK THAT IS APPROPRIATE TO THE APPLICA-

TION TO PUSH WORK PIECES THROUGH THE SAW. A push stick is a wooden or

non-metallic stick, usually homemade, that should be used whenever the size or shape

of the work piece would cause you to place your hands within six inches of the blade.

Use hold-downs, jigs, fixtures or feather boards to help guide and control the

work piece when the guard cannot be used. Use saw-blade guard and splitter for

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

• DO NOT PERFORM RIPPING, CROSSCUTTING OR ANY OTHER OPERATION

FREEHAND.

• NEVER reach around or over saw blade.

• STABILITY. Make sure the table saw is firmly mounted to a secure surface before use

and does not move.

3

English

• 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

EWALT service center for repair. The splitter must be in alignment with the saw blade

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".

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:
