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, al ways wear NIOSH/OSHA approved, properly fit ting face mask or res pi ra tor when us ing such tools.

GENERAL SAFETY RULES

Failure to follow these rules may result in serious personal injury.

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. Wear protective 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 startup 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. 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. 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. ALWAYS USE GUARDS, SPLITTER, AND ANTI- KICKBACK PAWLS 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 WORKPIECE 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 cross-cutting. Never use a fence or fence system for crosscutting. 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.

HOW TO ADJUST THE POSITIVE STOPS

This machine has positive stops that will allow you to quickly and accurately position the blade at 90° and 45° to the table. To check and adjust the positive stops:

1. Raise the blade to its fullest height.

2. Position a square (A) Fig. 40 against the blade and the table to check the angle.

3. If the blade is not 90° to the table, remove the lock screw located inside the hole (B) and slightly loosen the adjustment screw located underneath the lock screw. Rotate the tilting handwheel until the blade is at the correct angle. Tighten the adjustment screw until it bottoms. Replace the lock screw. Check the angle of tilt indicator on the handwheel is pointing to "0". If not, adjust it.

4. Tilt the blade as far as it will go by turning the tilting handwheel counter-clockwise.

5. Position a square (A) Fig. 41 against the blade and the table to check the angle.

6. If the blade is not 45° to the table, remove the lock screw located inside the hole (C) and slightly loosen the adjustment screw located underneath the lock screw. Rotate the tilting handwheel until the blade is 45° to the table. Tighten the adjustment screw until it bottoms. Replace the lock screw.

HOW TO ADJUST THE FENCE PARALLEL TO THE MITER GAUGE SLOTS

IMPORTANT: Be certain that the miter gauge slots are parallel with the blade before adjusting the fence.

Move the fence (A) Fig. 45 until the bottom edge is aligned with the edge of one of the miter gauge slots and lock it in place with the lock clamp (B). If the fence is not parallel to the slot, raise the lock clamp, and lift the fence off of the guide tube. Use a 3/16" hex wrench (not supplied) to tighten or loosen the adjustment screw (either C or D) Fig. 46 that applies.

IMPORTANT: Any necessary adjustments should be very small.

HOW TO CHANGE SPEEDS AND ADJUST BELT TENSION

This saw has a double V-belt drive that provides blade speeds of 3000 and 4500 RPM. To achieve the faster speeds, place the belts on the largest steps of the motor pulley and the smallest steps of the arbor pulley.

Shut off the power source to the machine.

1. Position the blade in the 90° position and lower the blade about two turns.

2. Loosen the bolt (A) Fig. 51 and remove the bolt (B).

3. Place a block of wood (C) Fig. 51A between the motor and the inside of the saw cabinet. Lower the motor against the block of wood until the belt tension is released.

4. Position the belts on the motor and spindle pulleys and raise the blade. The weight of the motor is sufficient to provide proper tension.

5. Tighten the bolt (A). Replace and tighten the bolt (B).

MACHINE USE

Common sawing operations include ripping and cross cutting plus a few other standard operations. As with all power machines, a certain amount of hazard is involved with the operation and use of the machine. Using the machine with the respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or completely ignored, personal injury can result. The following information describes the safe and proper method for performing the most common sawing operations.

The use of attachments and accessories not recommended be Delta may result in injury. Never operate the saw without the proper table insert for the saw blade or cutter installed.

QUICK OPERATIONS CHECKLIST

Before using the saw each time, verify the following:

1, The blade is tight.

2. The bevel angle and height lock-knobs are tight.

3. If ripping, ensure that the fence lock lever is tight and that the fence is parallel to the blade.

4. If crosscutting, ensure that the miter gauge knob is tight.

5. Proper eye, hearing, and respiratory equipment are being used.

6. The blade guard is properly attached and the anti-kickback pawls are functioning.

Failure to adhere to these common safety rules can greatly increase the likelihood of injury.

BLADE GUARD AND SPLITTER USE

The blade guard assembly provided with Delta saws (Fig. 52) 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. 52 prevent the workpiece and the cut-off piece from being thrown back at the operator. The 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.

4. 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).

Fig. 52

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. 53). 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. 54 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 with a washer through the slots provided in the miter gauge body.

Fig. 53

Fig. 54

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. 55). 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.

When using the block (B) Fig. 55 as a cut-

off gauge, position the rear end of the block so that the workpiece is clear of the block before it enters the blade.

Fig. 55

MITERING

Mitering (Fig. 56) is the same as crosscutting except the miter gauge (C) is locked at an angle other than 0°. Hold the workpiece firmly against the miter gauge and feed the work slowly into the blade to prevent the workpiece from moving.

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

Fig. 56

BEVEL CROSSCUTTING

Bevel crosscutting (Fig. 57) is the same as crosscutting except the bevel angle is set to an angle other than 0°.

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

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

COMPOUND MITERING

Compound Mitering (Fig. 58) 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.

RIPPING

Ripping (Fig. 59) 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.

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.

NEVER perform a ripping operation free-hand. Always lock the fence to the rail.

Always use a rip fence for ripping operations.

The workpiece must have a straight edge

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. 59). 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

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.

BEVEL RIPPING

Bevel ripping (Fig. 63) is the same as ripping except the bevel angle is set to an angle other than 0°.

When possible, place the fence on the right side of the blade so that the blade is tilted away from the fence and hands. keep your hands clear of the blade and use a pushstick to feed the workpiece if there is less than 6” between the fence and the blade.

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

USING AN ACCESSORY DADO HEAD

The blade guard and splitter assembly cannot be used when dadoing or moulding. It must be removed as described in “USING AN ACCESSORY MOULDING CUTTERHEAD” section.

Use pushsticks, hold-downs, jigs, fixtures, or featherboards to help guide and control the workpiece when the guard cannot be used.

You must make your own table insert (throat

plate) to use when cutting dados. The standard table insert will not work with dado cutters.

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. 64). 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.

65). The saw and cutter overlap is shown in Fig. 66 - (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.

Do not attempt to stack dado blades thicker than 13/16” (20mm) Do not use dado blades larger than 12” (305 mm) in diameter. Also, your accessory dado set must have a 1" arbor hole.

Attach the dado head set (D) Fig. 67 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.

Never use the dado head in a bevel position.

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

CONSTRUCTING A FEATHERBOARD

Featherboards are used to keep the work in contact with the fence and table (Fig.

69), and help prevent kickbacks. Dimensions for making a typical featherboard are shown in Fig. 70. Make your featherboard from a straight piece of wood that is free of knots and cracks. Clamp the featherboard to the fence and table so that the leading edge of the featherboard will support the workpiece until the cut is complete. An 8" high flat board can be clamped to the rip fence and the featherboard can be clamped to the 8" high board.

guard and splitter assembly cannot be used. Always replace the guard and

Use featherboards for all non-thru-sawing operations where the

splitter assembly when the non-thru-sawing operation is complete. Make sure the featherboard presses only on the portion of the workpiece in front of the blade.
