TERMINOLOGY

Terms: the following terms will be used throughout the manual and you should become familiar with them.

•Through-cut refers to any cut that completely cuts through the workpiece.

•Non through-cut refers to any cut that does not completely cut through the workpiece.

•Push stick refers to a wooden or plastic stick, usually homemade, that is used to push small workpiece 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 workpiece 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 workpiece

other than the operator’s hand.

Never perform freehand cutting.

•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.

Never perform plunge cutting.

•Resawing - Flipping material to make a cut the saw is not capable of making in one pass. Resawing is not recommended.

•Cove cutting - Coving is an operation where the work is fed at an angle across the blade. To reduce the risk of personal injury, do not perform cove cutting because table saw blades are not designed for

the excessive side loading needed.

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 through cutting operations. Keep the guard assembly in working order.

MAKING A PUSH STICK

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 end of the English section 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 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 DELTA 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.

OPERATION

NOTICE

OPERATIONAL CONTROLS AND ADJUSTMENTS

To reduce the risk of personal injury, turn

unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can

cause injury.

STARTING AND STOPPING THE SAW

Make sure that the saw has been turned

"OFF" before plugging cord into outlet. Do not touch the plug’s metal prongs when unplugging or plugging

in the cord.

1. The POWER switch (X) Fig. 19 is located underneath

the front left extension wing. To turn the saw "ON", push the round button (X) Fig. 19.

2. To turn the saw "OFF", push the button (Y) Fig. 19.

LOCKING SWITCH IN THE "OFF" POSITION

IMPORTANT: When the machine is not in use, the saw

should be turned off and the "ON" button locked out to prevent unauthorized use. To lock out “ON” button, use a standard long shackle lock (Z) Fig. 20, with a shackle that is at least 2-3/4" (70 mm) long and with shackle posts no larger than 9/32" (7 mm) thick.

FIG. 19

FIG. 20

In the event of a power outage (such as

a breaker or fuse trip), always move the switch to the "OFF" position until the main power is restored.

OVERLOAD PROTECTION

Your saw is supplied with overload protection. If the

FIG. 21

motor shuts off or fails to start due to overloading (cutting stock too fast, using a dull blade, using the saw beyond its capacity, etc.) or low voltage, let the motor cool three to five minutes. The overload will automatically reset itself and the machine can then be started again by pressing the "ON" button.

If the motor continually shuts off due to

overloading, contact a qualified electrician.

RAISING AND LOWERING THE BLADE

Raise or lower the blade with the left handwheel (AA) Fig. 21. Before raising or lowering the blade, be sure to loosen the lock knob (BB) Fig. 21 by turning it counterclockwise.

To raise the saw blade, turn the handwheel (AA), clockwise. To lower the saw blade, turn handwheel (AA) counterclockwise.

Tighten lock knob (BB) Fig. 21 to keep blade raised to your desired height. Only a small amount of force is required to lock the blade raising mechanism securely. Any added force merely puts unnecessary strain on the locking device.

For most applications, it is recommended that you raise the blade 1/8" (3.2 mm) to 1/4" (6.4 mm) above the top surface of the workpiece, as shown in Fig. 22. (NOTE: Guard removed for clarity only.)

NOTE: With hollow-ground blades, raise the blade to its maximum height to provide greater clearance.

FIG. 22

Lock the blade in position before starting the saw.

TILTING THE BLADE

Tilt the blade to the left using the right handwheel (CC) Fig. 23.

The blade tilting mechanism allows the blade to be tilted up to 45° to the left.

To tilt the saw blade, loosen the lock knob (DD) Fig. 23 counterclockwise and turn handwheel (CC). A pointer (EE) Fig. 24 indicates the angle of tilt on the scale, marked in 1/2-degree increments.

To lock the saw blade at your desired angle, tighten the lock knob (DD).

THROAT PLATE ADJUSTMENT

The throat plate (FF) Fig. 25 needs to be level to the saw table. If the throat plate is not level with the saw table, adjust the plate using four set screws (GG). Lower or raise set screws as needed to align throat plate level to the saw table.

RIVING KNIFE OPERATION AND ADJUSTMENT

POSITIONING THE RIVING KNIFE

The riving knife (J) Fig. 26 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.

(NOTE: Safety devices removed for clarity in Fig. 26. Be sure to always use safety devices when possible.)

The riving knife (J) Fig. 27 and Fig. 28 can be used in through cuts (where the workpiece is completely cut in two) and non-through cuts. The riving knife can be moved to the high position (Fig. 27) for through cuts and to the low position (Fig. 28) for non-through cuts.

NOTE: When adjusting the riving knife up or down, be sure to pull in a radial motion, as shown in Fig. 28A.

FIG. 24

FIG. 23

FIG. 26

FIG. 28A

To adjust the riving knife position, there are two methods:

FRONT-RELEASE (PRIMARY METHOD)

1. Pull front riving knife release handle (II) Fig. 29 in front

of the saw under the table, just above the gauge.

2. While holding handle, pull riving knife up until detent

(JJ) Fig. 30 engages for the through-cutting position.

3. While holding handle, push riving knife down until

detent (KK) Fig. 30 engages for the non-throughcutting position.

4. Release handle and pull on riving knife to make sure it

is in the locked position.

5. Replace throat plate.

RIVING KNIFE RELEASE LEVER (ALTERNATIVE METHOD)

1. Remove throat plate (FF) Fig. 25.

2. Push riving knife release lever (MM) Fig. 31 away from

the blade and pull riving knife up to lower detent (JJ) Fig. 30 for the through-cutting position.

3. Push riving knife release lever away from the blade

and push riving knife down to upper detent (KK) Fig. 30 for the non-through-cutting position.

4. Release lever and pull on riving knife to make sure it is

in the locked position.

5. Replace throat plate.

FIG. 29

Before connecting the table saw to the power source or operating the saw, always inspect the blade guard assembly and riving knife for proper alignment and clearance with saw blade. Check

alignment after each change of bevel angle. NOTE: DO NOT operate saw if riving knife is not locked

in the through-cutting or non through-cutting position. Fig. 31A shows the riving knife clamp locked down properly. Fig. 31B shows the clamp unlocked

When properly aligned, the riving knife will be in line with the blade at both table top level, and at the top of the blade.

Using a straight edge (NN), ensure that the blade (OO) is aligned with the riving knife (J) as shown in Fig. 32. (BE SURE THE STRAIGHT EDGE GOES BETWEEN THE TEETH AND RESTS ON THE BLADE BODY AND THE RIVING KNIFE FOR PROPER ALIGNMENT.)

If the riving knife and blade are out of line, see section,

Riving knifes must be matched to saw blade

Abrasive wheels or blades (including diamond)

RIVING KNIFE SELECTION

To minimize the risk of kickback and to insure proper cutting, the riving knife must be the proper thickness for the blade used.

The riving knife supplied with this table saw is the correct size for the blade supplied with the saw.

If a different blade is used, check the blade body, or plate, thickness and the blade kerf, or cutting, width marked on the blade or on the blade packaging. The riving knife thickness must be greater than the body thickness and less than the kerf width as shown in Fig. 39. If it is not, the riving knife MUST be replaced with one that has the correct thickness.

The riving knife provided with this saw is either 2.7 mm thick or 2.8 mm thick and will be marked in one of two ways:

The riving knife available as an accessory marketed by DELTA is marked as follows:

All DELTA blade body thickness and kerf width information is provided at www.deltaportercable.com.

If a different blade is used and the body thickness and kerf width dimensions are not provided, use the following procedure to determine the correct riving knife thickness:

1. Measure the body thickness of the blade.

2. Make a shallow cut in scrap material and measure the kerf

width.

3. Select the riving knife as shown in Fig. 39.

4. Slide the riving knife through the shallow cut (Fig. 41) made in step 2 to confirm the correct riving knife has been selected. The riving knife should not bind or drag through the cut.

IMPORTANT: If any dragging or binding of the material is encountered as it reaches the riving knife, turn unit off and disconnect machine from power source. Repeat steps 1–4 to make the proper riving knife selection before attempting another cut.

ADJUSTING 0° AND 45° POSITIVE STOPS

There are built in stops that can position the blade at 0° and 45°. If the blade is not properly at 0° when it is resting on the stop:

1. Adjust blade to 0° stop and back it off slightly.

2. Loosen the bevel stop nut (UU) slightly using supplied arbor wrench.

3. Using blade tilting handwheel (CC), position blade at exactly 0°.

4. Use 6 mm hex wrench inside the bevel stop nut (UU)to turn the stop into place. NOTE: The stop can be rotated either way to position stop against the trunnion.

5. Hold the stop in place and tighten the bevel stop nut (UU) with the supplied arbor wrench.

6. Verify position by beveling off and then coming back to the stop to check blade position.

NOTE: To adjust the 45° stop, use the other bevel stop nut (TT) and follow the same procedure above.

ADJUSTING BLADE TILT SCALE

ADJUSTING MITER SLOT PARALLEL TO BLADE

To reduce the risk of personal injury, turn

unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause

injury. The saw table was aligned at the factory. For accuracy,

check the alignment before beginning operation.

1. Place a combination square (ZZ) Fig. 46 on the table with one edge of the square in the miter gauge slot. Adjust the square so that the ruler's edge touches the face of the saw blade at the forward position. Lock the square.

2. Rotate the saw blade so that the same spot you used in STEP 1 is in the rear position (Fig. 47) and place ruler edge on the face of the saw at this spot. Both the front and rear measure ments should be the same.

3. Then, using a 10 mm hex wrench, loosen the four screws - one shown at (A1) Fig. 48 - that hold the table to the saw cabinet.

4. Adjust the front edge of the saw (as shown in Fig. 49). The pivot point on the rear edge of the saw is shown in Fig. 49.

5. Move table until the miter slot is parallel with the blade, according to the method described in STEPS 1 and 2.

6. Once miter slots are parallel to the blade, finger tighten the four bolts (one shown at (A1) Fig. 48). Check the parallel one last time and fully tighten the bolts.

7. Tilt the blade 45° (as shown in Fig. 50), and turn the saw blade by hand. Ensure that the blade does not contact the throat plate.

TAKING SLACK OUT OF RIVING KNIFE RELEASE CABLE

Over time, the riving knife release cable may develop slack and may not fully open the riving knife release clamp. To remove the slack out of the riving knife release cable:

1. Using a 7/16" open end wrench, move nut (B1) Fig. 51 (located underneath the fence in front of saw) away from saw cabinet.

2. Using a 7/16" wrench, tighten nut (D1) against the bracket (C1) and nut (B1).

To avoid the risk of injury, do not overtighten the cable. If the cable is too tight, the riving knife will be loose and will not function properly. After adjustments always check that the riving knife is securely clamped in the desired position by firmly pulling up on the knife.

ALIGNING THE RIP FENCE AND TABLE BOARD

See your fence instruction manual for instructions on adjusting the rip fence parallel to the miter gauge slot, as well as instructions for making sure the table board is flat to the extension wings and flat across the whole width of saw, wings and table board.

FIG. 51

CHANGING THE SAW BLADE

Use only 10" (254 mm) diameter blades with 5/8" (16 mm) arbor holes, rated at 4,300 rpm or higher.

To reduce the risk of injury, turn unit off

and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

1. Remove the throat plate (FF) Fig. 52, and raise the

saw blade to its maximum height.

2. Remove old blade, if needed, by holding red arbor

lock button (E1) Fig. 52. Use included arbor wrench to remove the blade retaining nut (F1). Remove old blade.

3. Place the new blade on the arbor with the teeth

pointing down as the blade rotates toward the front of the saw table.

4. Replace the blade retaining nut and throat plate.

MAXIMUM BLADE HEIGHT ADJUSTMENT

The saw is designed so that the top of blade can be raised to a maximum distance of 3-1/8" (79 mm) from the table surface. If the saw is not achieving this height, follow these steps:

1. Raise blade to its highest point, then back of slightly.

2. Loosen the blade height stop jam nut (G1) Fig. 53

slightly with a wrench.

FIG. 52

FIG. 53

3. Set blade height to 3-1/8" (79 mm).

4. Use a hex wrench in the stop bolt to turn the blade height stop into place against the arbor bracket. The stop can be

rotated in either direction until it jams against the trunnion.

5. Hold hex wrench in place and tighten the blade height stop jam nut.

6. Lower the blade and re-position against the blade height stop. Verify the height is still 3-1/8" (79 mm).

ADJUSTING BELT TENSION

1. Open the motor cover.

2. Loosen the bolt (H1) Fig. 54A, and carefully let the motor rest on the belts.

3. Correct belt tension is indicated with a 1/4" (6.4 mm) deflection in the center span of the pulleys, using light finger pressure.

4. When proper tension is achieved, tighten bolt (H1) Fig. 54A.

NOTE: For instructions on replacing the belts see the Maintenance section.

BLADE GUARD OPERATION

To reduce the risk of injury, turn unit off

and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

If there is a need to briefly raise the blade guard (for example, to make a measurement) the guard can be parked in a raised position. Lift the guard from the front (as shown in Fig. 54B) and raise guard shield until it snaps into a locked position above the table. One or both guard shields can be raised.

When done making the measurement (Figure 54C), return guard to operating position (Figure 54D).

Keep arms, hands and fingers away from

the blade to prevent serious injury.

To reduce the risk of injury, you must use

the saw blade guard for all through-cuts.

FIG. 54D

MACHINE USE

KICKBACK

Kickback is a dangerous condition! It is caused by the workpiece binding against the blade. The result is that the workpiece can move rapidly in a direction opposite to the feed direction. During kickback, the workpiece could be thrown back at the operator. It can also drag the operator’s hand back into the blade if the operator’s hand is at the rear of the blade. If kickback occurs, turn the saw "OFF" and verify the proper functioning of the riving knife, anti-kickback assembly and blade guard assembly before resuming work.

See Additional Safety Rules for Table Saws and follow all warnings provided regarding kickback.

Common sawing operations include through cuts (like ripping and cross cutting), non-through cuts (like dados and rabbets) 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.

TABLE SAW OPERATION SAFETY

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

Before using the saw, verify the following each and every time:

1. A. Always wear proper eye, hearing and respiratory equipment. B. Blade is tight. C. Bevel angle and height lock knobs are tight. D. If ripping, ensure fence lock lever is tight and fence is parallel to the blade. E. If crosscutting, miter gauge knob is tight. F. The blade guard /riving knife assemblies are properly attached and the anti-kickback teeth are functioning. G. Always inspect the guard and riving knife for proper alignment operation and clearance with saw blade. H. ALWAYS make sure both guards are in the down position in contact with the table before operating. 2 . To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and

removing accessories, before adjusting or changing set-ups or when making repairs. An accidental start-up can cause injury.

3. Before connecting the table saw to the power source or operating the saw, always inspect the guard and riving knife for proper operation, alignment and clearance with saw blade. Otherwise, personal injury may result.

4. This instruction manual does not provide information regarding the installation of a fence system. A fence system must be installed before use of the saw. Please refer to the fence instruction manual regarding the proper installation, alignment, and operation of the fence system.

5. The use of attachments and accessories not recommended by DELTA may result in injury.

6. You must use the saw blade guard and riving knife and anti-kickback assemblies for all through cuts. The anti-

kickback fingers mount to the riving knife and aid in preventing kickback. The riving knife prevents the wood kerf from closing and binding the blade. Be sure to replace or sharpen the anti-kickback fingers when the points become dull.

7. Ripping or crosscutting may cause saw to tip over while operating. If you desire to secure the saw to a stable surface, see instructions in section Securing Saw to a Permanent Location.

8. Never use the fence and miter gauge together. This may cause a kickback condition and injure the operator. The proper throat plate must be in place at all times to reduce the risk of a thrown workpiece and possible injury.

10. If your saw makes an unfamiliar noise or if it vibrates excessively, cease operating immediately until the source

has been located and the problem corrected.

11. Never perform freehand cutting, plunge cutting, resawing or cove cutting.

MAKING CUTS

There are two basic types of cutting with table saws: ripping and crosscutting. Cutting with the grain is ripping and cutting against the grain is crosscutting. With manmade materials, the distinction is made such that ripping is cutting to a different width and crosscutting describes cutting material across the shorter dimension.

When ripping, always use the fence to provide a guide for the material and guard against a kickback

situation.

When crosscutting, always use the miter gauge.

RIPPING

Never touch the free end of the workpiece or a free piece that is cut off, while the power is on and/or the saw blade is rotating. Piece may contact the blade resulting in a thrown workpiece or possible injury.

A rip fence should ALWAYS be used for ripping operations to prevent loss of control and personal injury. NEVER perform a ripping operation freehand. Always lock the fence to the rail.

When bevel ripping and whenever possible, place the fence on the side of the blade so that the blade is tilted away from the fence and hands. Keep hands clear of the blade and use a push stick to feed the workpiece if there is less than 6" (152 mm) between the fence and the blade.

Keep hands clear of the blade

Use a push stick to feed the workpiece if there is 2" to 6" (51 to 152 mm) between the fence and the blade. Use a narrow rip auxiliary fence and push block to feed the workpiece if there is 2" (51 mm) or narrower between the fence and the blade.

1. Lock the fence down where you want it to be. Remove the miter gauge.

2. Raise the blade so it is about 1/8" (3.2 mm) higher than the top of the workpiece.

3. Hold the workpiece flat on the table and against the fence (A) Fig. 55. Keep the workpiece about 1" (25 mm) away

from the blade.

FIG. 55

The workpiece must have a straight edge against the fence and must not be warped, twisted or bowed. Keep both hands away from the blade and away from the path of the blade. See proper hand position in Fig. 55.

4. Turn the saw on and allow the blade to come up to speed. Both hands can be used in starting the cut. When there is

approximately 12" (305 mm) left to be ripped, use only one hand, with your thumb pushing the material, your index and second finger holding the material down and your other fingers hooked over the fence. Always keep your thumb along side your first two fingers and near the fence.

5. Keep the workpiece against the table and fence and slowly feed the workpiece rearward all the way through the saw

blade. Continue pushing the workpiece until it is clear of the guard and it falls off the rear of the table. Do not overload the motor.

6. Never try to pull the workpiece back with the blade turning. Turn the switch off, allow the blade to stop, raise the anti-

kickback teeth on each side of the riving knife if necessary and slide the workpiece out.

7. When sawing a long piece of material or a panel, always use a work support. A sawhorse, rollers or outfeed assembly

provides adequate support for this purpose. The work support must be at the same height as the saw table.

Never push or hold onto the free or cut off side of the workpiece.

RIPPING SMALL PIECES

It is unsafe to rip small pieces. It is not safe to put your hands close to the blade. Instead, rip a larger piece to obtain the desired piece. When a small width is to be ripped and the hand cannot be safely put between the blade and the rip fence, use one or more push sticks. A pattern is included at the end of this manual to make push sticks. A push stick (B) Fig. 56 is included with this saw. Use the push stick(s) to hold the workpiece against the table and fence, and push the workpiece fully past the blade. See Fig. 56.

FIG. 56

BEVEL RIPPING

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

Before connecting the table saw to the power source or operating the saw, always inspect the blade guard assembly and riving knife for proper alignment and clearance with saw blade. Check alignment after each change of bevel angle.

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" (152 mm) between the fence and the blade.

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

CROSSCUTTING

NEVER touch the free end of the workpiece or a free piece that is cut off, while the power is ON and/or the saw blade is rotating. Piece may contact the blade resulting in a thrown workpiece and possible injury.

FIG. 57

To reduce the risk of injury, NEVER use the fence as a guide or length stop when crosscutting.

NEVER use a length stop on the free end of the workpiece when crosscutting. In short, the cut-off piece in any through-sawing (cutting completely through the workpiece) operation must never be confined — it must be allowed to move away from saw blade to prevent contact with blade resulting in a thrown workpiece and possibly injury.

Use caution when starting the cut to prevent binding of the blade guard assembly against the workpiece resulting in damage to saw and possible injury.

When using a block as a cut-off gauge, the block must be at least 3/4" (19 mm) thick and is very important that the rear end of the block be positioned so the workpiece is clear of the block before it enters the blade to prevent contact with blade resulting in a thrown workpiece and possibly injury.

Cross-cutting is cutting the wood across the grain. It 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" (3.2 mm) 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. 58).

FIG. 58

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 guage 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 fit the miter gauge with an auxiliary wood-facing that should be at least 1" (25 mm) higher than the maximum depth of cut, and should extend out 12" (305 mm) or more to one side or the other depending on which miter gauge slot is being used. This auxiliary wood-facing can be fastened to the front of the miter gauge by using two wood screws through the holes (D) Fig. 59 provided in the miter gauge body and into the wood-facing.

When cross-cutting a number of pieces to the same length, clamp a block of wood (E) Fig. 60 to the fence and use it as a cut-off gauge. The block (E) must be at least 3/4" (19 mm) 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.

FIG. 59

BEVEL CROSSCUTTING

Bevel crosscutting (Fig. 61) 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.

FIG. 60

FIG. 61

MITERING

Miter angles greater than 45˚ may force the blade guard assembly into the saw blade causing damage to the blade guard assembly and personal injury. Before starting the motor, test the operation by feeding the workpiece into the blade guard assembly. If the blade guard assembly contacts the blade, place the workpiece under the blade guard assembly, not touching the blade, before starting the motor.

Certain workpiece shapes, such as molding may not lift the blade guard assembly properly. With the power off, feed the workpiece slowly into the blade guard area and until the workpiece touches the blade. If the blade guard assembly contacts the blade, place the workpiece under the blade guard assembly, not touching the blade, before starting the motor.

This operation is the same as crosscutting except the miter gauge is locked at an angle other than 0°. Hold the workpiece FIRMLY against the miter gauge and feed the workpiece slowly into the blade (to prevent the workpiece from moving). See Fig. 62.

MITER GAUGE OPERATION

The miter gauge is equipped with adjustable index stops at 90°, 75°, 60°, 45° and 30°.

To rotate the miter gauge, loosen handle (G) Fig. 63, push the thumb lever (H) down and move the body of the miter gage (I) to the desired angle.

The miter gauge is equipped with a washer on the end of the bar which fits into the T-Slot groove (J) in the table. This allows the miter gauge to be pulled off the front edge of the table without falling. This allows for a longer cut-off capacity in front of the blade.

FIG. 62

To adjust the stops, loosen screws — two shown at (X) Fig. 63. Move stop to proper position and re-tighten screws (X).

COMPOUND MITERING

This is a combination of bevel crosscutting and mitering. Follow the instructions for both bevel crosscutting and mitering.

NOTE: Always use the miter slot (K) Fig. 64 which allows the blade to tilt away from the miter gauge and hands.

USING AN ACCESSORY DADO HEAD

To reduce the risk of injury, turn unit off and disconnect it from power source before installing and removing accessories, before adjusting or when making repairs. An accidental start-up can cause injury.

Do not attempt to stack dado blades thicker than 1" (25.4 mm) Do not use dado blades larger than 8" (200 mm) in diameter.

The riving knife and blade guard assemblies cannot be used when dadoing or molding. It must be removed as described in Riving Knife and Blade Guard Operations section. Use EXTREME care when using the dado without the blade guard assembly and riving knife.

FIG. 63

FIG. 64

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

The accessory dado head set throat plate (L) Fig. 65 must be used in place of the standard throat plate. Be sure the throat plate is level to the table before you proceed.

Always check dado blade clearance before plugging in the saw.

To reduce the risk of injury,

be sure to place the blade guard assembly and standard throat plate back in position and check adjustments when the dado cuts are complete. Reinstall blade guard assembly, anti-kickback assembly and riving knife.

Never use the dado head in a bevel

position.

Dadoing is cutting a rabbet or wide groove into the workpiece, as shown in Fig. 66. Most dado head sets are made up of two outside blades and four or five inside chippers, (Fig. 67). Various combinations of blades and chippers are used to cut grooves from 1/8" (3.2 mm) to 1" (25.4 mm) for use in shelving, making joints, tenoning, grooving, etc.

NOTE: The standard outer arbor flange nut assembly (M) Fig. 65 cannot be used with dado blade sets. A special nut (N) is included with the Unisaw to be used in dado applications. Tighten this arbor nut against the dado blade set. Do not discard the outer arbor flange nut. It

will be needed when reattaching the standard blade to the arbor.

To arrange a typical dado set:

1. The blades and chippers (DELTA 35-7670 is used

in this example) are heavily swaged and must be arranged so that the teeth do not hit each other during rotation. The heavy portion of the chippers should fall in the gullets of the outside blades (Fig. 68).

2. The blade and chipper profile is shown in Fig. 69.

Washers, if needed for fine width adjustment, can be placed anywhere between the outside blades and the chippers. A 1/4" (6.4 mm) groove is cut by using the two outside saws alone.

3. Position the teeth of the blade/chipper so that the

raker on one is beside the cutting teeth on the other.

4. Attach the dado head set to the saw arbor using the

arbor nut (N) Fig. 65.

NOTE: If a deep cut is required. Use several successive passes rather than attempting to make it with one pass. Maximum dado width on this saw is 1" (25.4 mm). DO NOT USE WIDER COMBINATIONS.

FIG. 65

FIG. 66

FIG. 67

To reduce the risk of injury, always return and fasten the riving knife and blade guard assemblies to the proper operating position for normal through sawing operations. Also, be sure the standard throat plate is back in position.

HOW TO USE A MOLDING CUTTERHEAD

The riving knife and blade guard assemblies cannot be used when dadoing. It must be removed as described in Riving Knife and Blade Guard Operations section. Use EXTREME care when using the dado without the blade guard assembly and riving knife.

Use pushsticks, hold-downs, jigs,

FIG. 70

fixtures or featherboards to help guide and control the workpiece when the guard cannot be used.

Never use a molding cutterhead (R) Fig. 70 in a bevel position. Always use the proper molding cutterhead throat plate (S).

Never run the stock between the fence and the molding cutterhead. Irregular-shaped wood will cause kickback.

Give special attention to the grain

FIG. 71

direction. Make all cuts in the same direction as the grain whenever possible.

Molding is cutting a shape on the edge or face of the workpiece with a special molding cutterhead.

The molding head consists of a cutterhead that can be fitted with various shapes of steel cutters (Fig. 71). 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 seat

properly. NOTE: The standard outer arbor flange nut assembly

(M) Fig. 65 cannot be used with a molding cutterhead. A special nut (N) is included with the Unisaw to be used

FIG. 72

in these applications. Tighten this arbor nut against the molding cutterhead. Do not discard the outer arbor

flange nut. It will be needed when reattaching the standard blade to the arbor.

1. You can easily attach a molding cutterhead (R) Fig. 70 to the saw arbor. Also, you must use the accessory molding cutterhead throat plate (S) in place of the standard throat plate. Be sure the throat plate is level to the table before you proceed.

2. When using the molding cutterhead, add wood-facing (T) to the face of the rip fence (Fig. 72). Attach the wood facing to the fence either with wood screws through holes drilled in the fence, or with two clamps. Stock that is 3/4" (19 mm) thick is suitable for most work, although an occasional job may require 1" (25 mm) 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. 71 shows a typical molding operation.

USING AUXILIARY WOOD FACING

Add a wood facing (U) Fig. 73 to one or both sides of the rip fence when you perform special operations (molding cutterhead, etc.). Depending on the fence, attach the wood facing to the fence either with wood screws through holes drilled in the fence, or with two clamps. For most work, 3/4" (19 mm) stock is suitable, although an occasional job may require 1" (25 mm) facing.

CONSTRUCTING AND USING A FEATHERBOARD

Featherboards are used to keep the work in contact with the fence and table (Fig. 74), and help prevent kickback.

Dimensions for making a typical featherboard are shown in Fig. 75. 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" (203 mm) high flat board can be clamped to the rip fence and the featherboard can be clamped to the 8" (203 mm) high board.

Use featherboards for all non-through sawing operations where the blade guard and antikickback assemblies cannot be used. Always replace the blade guard and anti-kickback assemblies when the non-through sawing operation is complete. Make sure the featherboard presses only on the portion of the workpiece in front of the blade.

If you are using the DELTA accessory featherboard, the one on the table (V) Fig. 76 can be inserted and tightened against the appropriate miter slot. If you use a featherboard on top (not shown) it can be screwed into a board that is clamped to the fence. Be sure all featherboards are tightly fastened before operations.
