GENERAL SAFETY RULES

READ AND UN DER STAND ALL WARNINGS AND OP ER AT ING IN STRUC TIONS BE FORE USING THIS EQUIP MENT. Failure to follow all instructions listed below, may result in electric shock, fire, and/or serious personal injury or property damage.

IMPORTANT SAFETY INSTRUCTIONS

1. FOR YOUR OWN SAFETY, READ THE INSTRUCTION MANUAL BEFORE OPERATING THE MACHINE. Learning

the machine’s application, limitations, and specific hazards will greatly minimize the possibility of accidents and injury.

2. WEAR EYE AND HEARING PROTECTION. ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye protection equipment should comply with ANSI Z87.1 standards. Hearing equipment should comply with ANSI S3.19 standards.

3. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip protective footwear is recommended. W ear pr otective hair covering to contain long hair.

4. 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 prevent tripping or placing arms, hands, and fingers in danger.

5. MAINTAIN ALL TOOLS AND MACHINES IN PEAK CONDITION. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Poorly maintained tools and machines can further damage the tool or machine and/or cause injury.

6. CHECK FOR DAMAGED PARTS. Before using the machine, check for any damaged parts. Check for alignment of moving parts, binding of moving parts, breakage of parts, and any other conditions that may affect its operation. A guard or any other part that is damaged should be properly repaired or replaced with Delta or factory authorized replacement parts. Damaged parts can cause further damage to the machine and/or injury.

7. KEEP THE WORK AREA CLEAN. Cluttered areas and benches invite accidents.

8. KEEP CHILDREN AND VISITORS AWAY. Your shop is a potentially dangerous environment. Children and visitors can be injured.

9. 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. Do not touch the plug’s metal prongs when unplugging or plugging in the cord.

10. USE THE GUARDS. Check to see that all guards are in place, secured, and working correctly to prevent injury.

11. REMOVE ADJUSTING KEYS AND WRENCHES BEFORE STARTING THE MACHINE. Tools, scrap pieces, and other debris can be thrown at high speed, causing injury.

12. USE THE RIGHT MACHINE. Don’t force a machine or an attachment to do a job for which it was not designed. Damage to the machine and/or injury may result.

13. USE RECOMMENDED ACCESSORIES. The use of accessories and attachments not recommended by Delta may cause damage to the machine or injury to the user.

14. USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. 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. See the Extension Cord Chart for the correct size depending on the cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

15. SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece when practical. Loss of control of a workpiece can cause injury.

16. FEED THE WORKPIECE AGAINST THE DIRECTION OF

THE ROTATION OF THE BLADE, CUTTER, OR ABRASIVE SURFACE. Feeding it from the other direction will cause the

workpiece to be thrown out at high speed.

17. DON’T FORCE THE WORKPIECE ON THE MACHINE. Damage to the machine and/or injury may result.

18. DON’T OVERREACH. Loss of balance can make you fall into a working machine, causing injury.

19. NEVER STAND ON THE MACHINE. Injury could occur if the tool tips, or if you accidentally contact the cutting tool.

20. NEVER LEAVE THE MACHINE RUNNING UNATTENDED. TURN THE POWER OFF . Don’ t leave the machine until it comes to a complete stop. A child or visitor could be injured.

21. TURN THE MACHINE “OFF”, AND DISCONNECT THE MACHINE FROM THE POWER SOURCE before installing or removing accessories, changing cutters, adjusting or changing set-ups. When making repairs, be sure to lock the start switch in the “OFF” position. An accidental startup can cause injury.

22. MAKE YOUR WORKSHOP CHILDPROOF WITH

PADLOCKS, MASTER SWITCHES, OR BY REMOVING STARTER KEYS. The accidental start-up of a machine by

a child or visitor could cause injury.

23. 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 injury.

24.

AND DISBURSE DUST OR OTHER AIRBORNE PARTICLES, INCLUDING WOOD DUST, CRYSTALLINE SILICA DUST AND ASBESTOS DUST . Dir ect 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. Exposure to the dust may cause serious and permanent respiratory or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid breathing the dust, and avoid prolonged contact with dust. Allowing dust to get into your mouth or eyes, or lay on your skin may promote absorption of harmful material. Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for the dust exposure, and wash exposed areas with soap and water .

USE OF THIS TOOL CAN GENERATE

ADDITIONAL SPECIFIC SAFETY RULES

FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY.

1. DO NOT OPERATE THIS MACHINE until it is assembled and installed according to the instructions.

2. OBTAIN ADVICE FROM YOUR SUPERVISOR, instructor, or another qualified person if you are not familiar with the operation of this machine.

3. FOLLOW ALL WIRING CODES and recommended electrical connections.

4. ALWA YS USE GUARDS, SPLITTER, AND ANTI-KICKBACK PA WLS whenever possible, including through sawing. Check to see that they are in place, secured and working correctly. Test the anti-kickback pawl action before ripping by pushing the wood under the anti-kickback teeth. The teeth must prevent the wood from being thrown toward the front of the saw.

5. CUTTING THE WORKPIECE WITHOUT THE USE OF A

FENCE OR MITER GAUGE IS KNOWN AS “FREEHAND” CUTTING. NEVER perform “free-hand” operations. Use

either the fence or miter gauge to position and guide the workpiece.

6. HOLD THE WORKPIECE FIRMLY against the miter gauge or fence.

7. CUTTING COMPLETELY THROUGH THE WORK-PIECE IS KNOWN AS “THROUGH-SAWING”. Ripping and crosscutting are through-sawing operations. Cutting with the grain is ripping. Use a fence or fence system for ripping. NEVER use a miter gauge for ripping. Use push sticks for ripping a narrow workpiece. Cutting across the grain is crosscutting. Never use a fence or fence system for cross-cutting. Instead, use a miter gauge.

8. KICKBACK IS THE NATURAL TENDENCY OF THE

WORKPIECE TO BE THROWN BACK AT THE OPERATOR

when the workpiece initially contacts the blade or if the workpiece pinches the blade. Kickback is dangerous and can result in serious injury.

AVOID KICKBACK by:

A. keeping blade sharp and free of rust and pitch. B. keeping rip fence parallel to the saw blade. C. using saw blade guard and splitter for every possible

operation, including all through sawing. D. keeping splitter aligned with sawblade. E. keeping the anti-kickback pawls in place and

sharpened. F. pushing the workpiece past the saw blade prior to

release. G. never ripping a workpiece that is twisted or warped, or

does not have a straight edge to guide along the fence. H. using featherboards when the anti-kickback device or

the guard and splitter cannot be used. I. never sawing a large workpiece that cannot be

controlled. J. never using the fence as a guide when crosscutting. K. never sawing a workpiece with loose knots, flaws, nails

or other foreign objects. L. never ripping a workpiece shorter than 10”.

SOME MATERIALS ARE TOO HARD AND

SLIPPERY FOR THE ANTI-KICKBACK PAWLS TO BE EFFECTIVE. Plastic and compositions (like hardboard) may be

cut on your saw, but be especially attentive to following proper set-up and cutting procedures to prevent any kickbacks when cutting these materials.

9. USE THE CORRECT SAWBLADE 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.

10. NEVER USE ABRASIVE WHEELS on this saw.

11. DO NOT CUT METAL WITH THIS SAW.

12. REMOVE CUT-OFF PIECES AND SCRAPS from the table before starting the saw. The vibration of the machine may cause them to move into the saw blade and be thrown out.

13. CUT-OFF PIECES CAN BE THROWN BACK AT THE OPERATOR. For large cut-off pieces, use a push stick to push the piece past the blade and off the back of the saw table. Do not reach across sawblade. Be careful that small pieces do not contact the blade.

14.

NEVER ATTEMPT TO FREE A STALLED SAW BLADE WITHOUT FIRST TURNING THE MACHINE OFF. If a

workpiece 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.

15. NEVER START THE MACHINE with the workpiece against the blade.

16. NEVER run the workpiece between the fence and a moulding cutterhead.

17. KEEP ARMS, HANDS, AND FINGERS away from the blade. Use a push stick to push small workpieces through the saw. A push stick is a small wooden stick, usually homemade, that should be used whenever the size or shape of the workpiece would cause you to place your hands within six inches of the blade. See “CONSTRUCTING A PUSH STICK” in the back of this manual for guidance on making your own.

18. AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause a hand to move into the blade.

19. NEVER have any part of your body in line with the path of the saw blade.

20. NEVER REACH AROUND or over the saw blade.

21. PROPERLY SUPPORT LONG (3 feet or longer) OR WIDE (36” or wider) WORKPIECES. If extension tables wider than 24” are attached to the saw, bolt the saw stand to the floor, or use a sturdy outrigger support to prevent tipping.

22. PREVENT MOTION OF THE SAW WHILE IN USE. If the mobility kit is installed, lower the foot pedal and level the feet so the saw does not rock, walk, slide or tip. If necessary, secure the stand to the floor.

23. NEVER PERFORM LAYOUT, assembly or set-up work on the table/work area when the machine is running.

24. TURN THE MACHINE “OFF” AND DISCONNECT THE MACHINE from the power source before installing or removing accessories, changing the sawblade, or adjusting or changing set-ups. Lock switch in the “OFF” position when making repairs.

25. CLEAN THE TABLE/WORK AREA BEFORE LEAVING THE MACHINE. Lock the switch in the “OFF” position to prevent unauthorized use.

POWER CONNECTIONS

A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of the same characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the machine.

Do not expose the machine to rain or operate the machine in damp locations.

MOTOR SPECIFICATIONS

Your machine is wired for 120/240 Volt, 60 HZ alternating current. Before connecting the machine to the power source, make sure the switch is in the “OFF” position.

GROUNDING INSTRUCTIONS

This machine must be grounded while in use to protect the operator from electric shock.

1. All grounded, cord-connected machines:

In the event of a malfunction or breakdown, grounding provides a path of least resistance 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 yellow 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 instructions are not completely understood, or

if in doubt as to whether the machine is properly grounded. Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that

accept the machine’ s plug, as shown in Fig. A. Repair or replace damaged or worn cord immediately.

2. 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 illustrated 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 2-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 .

NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.

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.

BLADE GUARD AND SPLITTER USE

Delta saws (Fig. 63) must be used for all through-sawing operations. The splitter prevents the kerf from closing and

binding the blade, causing kickback. The anti-kickback pawls (A) Fig. 62 prevent the workpiece and the cut-off piece from being thrown back at the operator. The plastic guard prevents dust and debris from being thrown at the operator. To use the guard properly:

1. Make sure that the splitter is aligned with the blade as described in the section “BLADE GUARD AND

SPLITTER ASSEMBLY AND ALIGNMENT.”

2. Replace or sharpen the anti-kickback pawls when they become dull.

3. Keep the guard clean for visibility and free motion.

4. Do not use solvent or lubricants on the guard. They may severely damage the plastic.

5. Use caution when feeding workpieces that may catch on the guard and cause a bind, or force the guard into the blade (such as when cutting moulding).

The blade guard assembly provided with

Fig. 63

CROSS-CUTTING

Cross-cutting requires the use of the miter gauge to posi tion and guide the work. Before starting the cut, raise the blade so that it is about 1/8” (3.2mm) higher than the top of the workpiece. Place the work against the miter gauge and advance both the gauge and work toward the saw blade (Fig. 64). You can use the miter gauge in either table slot. Start the cut slowly and hold the work firmly against the miter gauge and the table. Keep both hands on the miter gauge and workpiece. Do not touch the cut-off piece. Feed the workpiece steadily through the blade until the workpiece is completely cut. Shift the workpiece slightly sideways away from the blade, then pull the workpiece and miter gauge back to the starting position. Remove the workpiece, then use a push stick to push the cut-off piece past the blade and off the table before beginning the next cut.

For added safety and convenience, you can attach an auxiliary wood-facing (C) Fig. 65 to the miter gauge. This facing should be at least 1" higher than the maximum depth of cut, and should extend out 12" or more to one side or the other depending on which miter gauge slot is used. Attach this auxiliary wood-facing (C) to the front of the miter gauge by using two wood screws (A) through the holes provided in the miter gauge body.

Fig. 64

Never use the fence as a cut-off gauge when cross-cutting.

When cross-cutting a number of pieces to the same length, clamp a block of wood (B) to the fence and use it as a cutoff gauge (Fig. 66). The block (B) must be at least 3/4" thick to prevent the cut-off piece from binding between the blade and the fence during removal from the saw table. Always position this block of wood in front of the saw blade. Once the cut-off length is determined, lock the fence and use the miter gauge to feed the work into the cut.

greater than 45° may force the guard into the saw blade and damage the guard. Before starting the motor, test the operation by feeding the workpiece into the guard. If the guard contacts the blade, place the workpiece under the guard, not touching the blade, before starting the motor. Certain workpiece shapes, such as mouldings, may not lift the guard properly. Feed the work slowly to start the cut.

the miter gauge and your hands.

COMPOUND MITERING

Compound Mitering (Fig. 69) is a combination of bevel crosscutting and mitering, where the blade is beveled to an angle other than 0° and the miter gauge is locked at an angle other than 0 degrees. Always use the miter slot (D) which allows the blade to tilt away from the miter gauge and hands.

When possible, use the right miter gauge slot when bevel crosscutting so that the blade tilts away from

Use caution when starting the cut to prevent binding of the guard against the workpiece.

RIPPING

Ripping (Fig. 70) is cutting lengthwise through a board. The rip fence (A) is used to position and guide the work. One edge of the work rides against the rip fence while the flat side of the board rests on the table.

You must use the saw blade guard. On Delta saws, the guard has anti-kickback pawls to prevent kickback, and a splitter to prevent the wood kerf from closing and binding the blade. Be sure to replace or sharpen the anti-kickback devices when the points become dull.

Always use a rip fence for ripping operations. NEVER perform a ripping operation free-hand. Always lock the fence to the rail.

The workpiece must have a straight edge against the fence, and must not be warped, twisted or bowed.

1. Before starting the cut, raise the blade so that it is about 1/8” (3.2mm) higher than the top of the workpiece. Start the motor and advance the work, holding it down and against the fence. Never stand in the line of the saw cut when ripping. When the rip width is 6 inches or wider, hold the work with both hands and push it along the fence and into the saw blade (Fig.

70). Feed force when ripping should always be applied between the saw blade and the fence. Never pull the workpiece from the back of the saw. The work should then be fed through the saw blade with the right hand. Keep pressure on the workpiece against the fence and down on the saw table. Ensure that you have adequate outfeed support for the workpiece and KEEP YOUR HANDS AWAY FROM THE SAW BLADE.

2. When the workpiece is past the blade, the work will either stay on the table or tilt up slightly and be caught by the end of the guard. Alternately, the feed will continue to the end of the table, and be lifted and brought along the outside edge of the fence. When ripping boards longer than three feet, use a work support at the rear of the saw to keep the workpiece from falling off the saw table.

3. If the size or shape of the workpiece would cause your hands to be within six inches of the saw blade, use a push stick to complete the cut (Fig. 71) The push stick can easily be made from scrap material as explained in the section

“CONSTRUCTING A PUSH STICK.”

4. Ripping narrow pieces can be dangerous. If possible, rip the narrow piece from the larger piece. If the workpiece is short enough, use a pushboard. (A pushboard can be constructed as shown in Fig. 72 and used as shown in Fig. 73.)

”

NOTE: In Fig. 73, the guard and splitter have been removed for clarity. Use the guard and splitter when ripping.

5. For longer pieces, use one or more pushsticks to avoid placing your hands between the fence and the blade. Always use care to avoid binding narrow strips between the anti-kickback pawls and the splitter.

NOTE: Some special operations (moulding cutterhead, etc.) require the addition of an auxiliary wood facing to the fence, as

explained in the section “USING AUXILIARY WOOD FACING,” and use of a push stick.

USING A MOULDING CUTTERHEAD

Moulding is cutting a shape on the edge or face of the workpiece with a special moulding cutterhead.

The moulding head consists of a cutterhead in which can be mounted various shapes of steel knives (Fig. 75). Each of the three knives in a set is fitted into a groove in the cutterhead and securely clamped with a screw. Keep the knife grooves free of sawdust to allow the cutter to seating properly.

1. You can easily attach a moulding cutterhead (A) Fig. 77 to the saw arbor. Also, you must use the accessory moulding cutterhead table insert (B) in place of the standard table insert.

2. When using the moulding cutterhead, add wood-facing (C) to the face of the rip fence (Fig. 78). The wood-facing is attached to the fence with wood screws through holes which must be drilled in the fence. Stock that is 3/4" inch thick is suitable for most work, although an occasional job may require 1" facing.

3. Position the wood-facing over the cutterhead with the cutterhead below the surface of the table. Turn the saw on and raise the cutterhead. The cutterhead will cut its own groove in the wood-facing. Fig. 78 shows a typical moulding operation.

Never use a moulding cutterhead in a bevel position.

Dadoing is cutting a rabbet or wide groove into the workpiece. Most dado head sets are made up of two outside saws and four or five inside cutters, (Fig. 80). Various combinations of saws and cutters are used to cut grooves from 1/8" to 13/16" for use in shelving, making joints, tenoning, grooving, etc. The cutters are heavily swaged and must be arranged so that the teeth do not hit each other during rotation. The heavy portion of the cutters should fall in the gullets of the outside saws (Fig. 80). The saw and cutter overlap is shown in Fig. 81 - (A) being the outside saw, (B) an inside cutter, and (C) a paper washer or washers, used as needed to control the exact width of groove. A 1/4"groove is cut by using the two outside saws. Position the teeth of the saws so that the raker on one saw is beside the cutting teeth on the other saw.

Attach the dado head set (D) Fig. 82 to the saw arbor. NOTE: If the arbor nut does not fully engage the thread on the arbor, remove the outside arbor flange and tighten the arbor

nut against the dado head set body. Do not lose the outside arbor flange. It will be needed when reattaching a blade to the arbor.

Do not attempt to stack dado blades thicker than 13/16” (20mm) Do not use dado blades larger than 8”

Never use the dado head in a bevel position.

Always install the blade guard and standard table insert after the operation is complete.

A typical dado operation is illustrated in Fig. 83.

USING AUXILIARY WOOD FACING

Add a wood facing (A) Fig. 84 to one or both sides of the rip fence when you perform special operations (moulding cutterhead, etc.). Depending on the fence, attach the wood facing or the fence either with wood screws through holes drilled in the fence, or with two clamps. For most work, 3/4” stock is suitable, although an occasional job may require 1” facing.
