IMPORTANT SAFETY INSTRUCTIONS

_ WARNING: When using electric tools, basic safety precautions should always be

followed to reduce risk of fire, electric shock, and personal injury, including the following."

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

Double Insulation

Double insulated tools are constructed throughout with two separate layers of electrical insulation or one single layer of reinforced 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 atwo prong plug which permits you to use extension cords without concern for maintaining a ground connection.

NOTE: Double insulation does not take the place of normal safety precautions when operating this tool. The secondary insulation system is for protection against injury resulting from a possible failure of the primary insulation within the tool.

i_CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or

replace damaged cords.

Polarized Plugs

Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk of electric shock. When provided, this plug will fit in the polarized outlet only one way. If the

plug does not fit fully in 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.

Safety Instructions For All Tools

AWARNING: To reduce the risk of eye injury, ALWAYS use eye protection when

operating the miter saw.

• KEEP GUARD IN PLACE and in working order.

• 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,

• DON'T 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,

• WEAR PROPERAPPAREL. 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 $12.6 ($3.19) hearing protection

• NIOSH/OSHA/MSHA respiratory protection

• SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece on the table and against the fence or when your hand will be dangerously close to the blade within 6" (152 mm). It is safer than using your hand and it frees both hands to operate tool

• DON'T OVERREACH. Keep proper footing and balance at alltimes. Loss of balance may cause personal injury,

• MAINTAIN TOOLS WITH CARE. 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,

• 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. An accidental start-up can cause injury, Do not touch the plug's metal prongs when unplugging or plugging in the cord.

• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure that the switch is in the "OFF" position before plugging in the power cord.

• USE PROPER EXTENSION CORD. Make sure your extension cord is ingood condition. If your product is equipped with a cordset, use only 3-wire extension cords that have 3-prong grounding-type plugs and 3-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.

• DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to tool and possible personal injury may occur.

• DO NOT force cutting action. Stalling or partial stalling of motor can cause damage. To the machine or blade and/or serious injury.

• ALLOW THE MOTOR TO COME TO FULL SPEED priorto starting cut. Starting the cut too soon may cause damage to the machine or blade and/or serious injury."

• NEVER CUT FERROUS METALS (Those with any iron or steel content) or masonry. Either of these can cause the carbide tips to flyoff the blade at high speeds causing serious injury.

• DO NOTUSEABRASIVE WHEELS. The excessive heat and abrasive particles generated by them may damage the saw and cause personal injury.

• NEVER have any part of your body in line with the path of the saw blade. Personal injury will occur.

• NEVER apply blade lubricant to a running blade. Applying lubricant could cause your hand to move into the blade resulting in serious injury.

• DO NOT place either hand in the blade area when the saw is connected to the power source. Inadvertent blade activation may result in serious injury.

• DO NOT PERFORM FREE-HAND OPERATIONS (workpiece not supported by table and fence). Hold the work firmly against the fence and table. Free-hand operations on a miter saw could cause the workpiece to be thrown at high speeds, causing serious injury.

• NEVER REACH AROUND or behind the saw blade. A blade can cause serious injury.

• DO NOT reach underneath the saw unless it is unplugged and turned off. Contact with saw blade may cause personal injury.

• SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. Vibration can

possibly cause the machine to slide, walk, or tip over, causing serious injury.

• USE ONLY CROSSCUT SAW BLADES recommended for miter saws. For best results, do not use carbide tipped blades with hook angles in excess of 7 degrees. Do not use

blades with deep gullets. These can deflect and contact the guard, and can cause damage to the machine and/or serious injury.

• USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this tool to

prevent damage to the machine and/or serious injury.

• INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or damaged blade can come apart and pieces can be thrown at high speeds, causing serious

injury. Replace cracked or damaged blades immediately.

• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning the blade and blade clamps allows you to check for any damage to the blade or blade clamps. A

cracked or damaged blade or blade clamp can come apart and pieces can be thrown at high speeds, causing serious injury.

• DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the

plastic guard. The polycarbonate material used in the guard is subject to attack by certain

chemicals.

• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED. Small chip accumulation under the saw may interfere with the saw blade or may cause

instability of workpiece when cutting.

• USE ONLY BLADE CLAMPS specified for this tool to prevent damage to the machine and/or serious injury.

• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can cause themachine to overheat, damaging the machine and possibly causing a short which could cause serious injury.

• KEEP ARMS, HANDS, AND FINGERS away from the blade to prevent severe cuts. Clamp all workpieces that would cause your hand to be within 6" (152 mm) of the saw

blade.

• NEVER LOCK THE SWITCH IN THE "ON" position. Severe personal injury may result.

• TURN OFF THE MACHINE and allow the blade to come to a complete stop before raising the arm and prior to cleaning the blade area, removing debris in the path of the blade, before servicing or adjusting tool A moving blade can cause serious injury.

Press down lightlyon the operating handle and pull out the lock down pin, as shown in Figure 2. Gently release the downward pressure and hold the arm allowing it to rise to its full height. Use

the lock down pin when carrying the saw from one place to another. Always use the carrying handle to transport the saw or the hand indentations shown in Figure 2 and 4.

Bench Mounting

Holes are provided in all four feet to facilitate bench mounting, as shown in Figure 2. (Two different sized holes are provided to accommodate different sizes of screws. Use either hole, it is not necessary to use both.) Always mount your saw firmly to a stable surface to prevent movement. To enhance the tool's portability, it can be mounted to a piece of 1/2" (12.7 mm)

or thicker plywood which can then be clamped to your work support or moved to other job sites and reclamped.

NOTE" If you elect to mount your saw to a piece of plywood, make sure that the mounting screws don't protrude from the bottom of the wood. The plywood must sit flush on the work support. When clamping the saw to any work surface, clamp only on the clamping bosses

where the mounting screw holes are located. Clamping at any other point will surely interfere with the proper operation of the saw.

_CAUTION: Toprevent binding and inaccuracy, be sure the mounting surface is not warped

or otherwise uneven. If the saw rocks on the surface place a thin piece of material under one

saw foot until the saw sits firmly on the mounting surface.

To adjust the right 45° bevel angle, loosen the bevel lock knob (L) and pull the bevel stop

override knob (S)to override the 0° bevel stop. When the saw is fully to the right, if the pointer does not indicate exactly 45°, turn the right bevel stop screw (O)until the pointer indicates 45°.

To adjust the left 45° bevel stop, first loosen the bevel lock knob (L)and tilt the head to the

left. If the pointer does not indicate exactly 45°, turn the left bevel stop screw until the pointer reads 45°.

FIG. 8

ADJUSTING THE BEVEL STOP TO 33.9° (FIG. 8) NOTE: Adjust the 33.9° bevel angles only after performing the 0° bevel angle and pointer

adjustment. Toset the 33.9° bevel angle, flip out the stop pawls (P). Loosen the bevel lock knob (L)and tilt

the head to the left. Ifthe pointer does not indicate exactly 33.9°, turn the screw contacting the pawl until the pointer reads 33.9°. To adjust the right 33.9° bevel angle, flip out the stop pawl. Loosen the bevel lock knob (L) and pull the bevel stop override button (S)to override the 0° bevel stop. When the saw is fully to the right, if the pointer does not indicate exactly 33.9°, turn the screw contacting the pawl

until the pointer indicates 33.9 °.

FENCE ADJUSTMENT (FIG. 8)

_WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect it from the power source before attempting to move it, change

accessories or make any adjustments.

In order that the saw can bevel to a full 48° leftor right, the fences can be adjusted to provide clearance To adjust a fence, loosenthe plastic knob (Figure 8, R),and slide the fence outward

Make a dry run with the saw turned off and check for clearance. Adjust the fence to be as close to the blade as practical to provide maximum workpiece support, without interfering

with arm up and down movement. Tighten knob securely. When the bevel operations are

complete, don't forget to relocate the fence. NOTE: The guide groove of the fences can become clogged with sawdust. If the guide

groove becomes clogged, use a stick, low pressure air or a vacuum to clear.

AUTOMATIC ELECTRIC BRAKE (FIG. 2)

Your saw is equipped with an automatic electric blade brake which stops the saw blade within 5 seconds of trigger release. This is not adjustable.

On occasion, there may be a delay after trigger release to brake engagement. On rare

occasions, the brake may not engage at all and the blade will coast to a stop.

Ifa delay or "skipping" occurs, turn the saw on and off 4 or 5 times. Ifthe condition persists, have the tool serviced by an authorized DEWALT service center.

Always be sure the blade has stopped before removing it from the kerf plate. The brake is not a substitute for guards. Ensure your own safety by giving the saw your complete attention.

GUARD ACTUATION AND VISIBILITY

i_CAUTION: Pinch Hazard. Toreduce the risk of injury, keep thumb underneath the handle when pulling the handle down. The lower guard will move up as the handle is pulled down which could cause pinching.

The blade guard on your saw has been designed to automatically raise when the arm is

brought down and to lower over the blade when the arm is raised.

The guard can be raised by hand when installing or removing saw blades or for inspection of the saw. NEVER RAISE THE BLADE GUARD MANUALLY UNLESS THE SAW IS TURNED

OFF. NOTE: Certain special cuts of large material will require that you manually raise the guard.

Refer to Cutting Large Material under Special Cuts.

The front section of the guard is Iouvered for visibility while cutting. Although the louvers

dramatically reduce flying debris, they are openings in the guard and safety glasses should be worn at all times when viewing through the louvers.

MITER LOCK ADJUSTMENT (FIG. 9)

The miter lock rod should be adjusted if the table of the saw can be moved when the

miter lock handle is locked down. To adjust, put the miter lock handle inthe up position. Using a slotted screwdriver, adjust the lock rod in 1/8 clockwise turn increments to

increase the lock force. To ensure the miter lock is functioning properly, re-lock miter lock handle to a non-detent miter angle.

FIG. 9

Brushes (Fig. 2)

_WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect it from the power source before attempting to move it, change

accessories or make any adjustments.

Inspect carbon brushes regularly by unplugging the tool, removing the motor end cap (Fig. 2) and removing the brush cap that holds the spring-loaded brush assembly. Keep

brushes clean and sliding freely in their guides. Always replace a used brush in the same orientation in the holder as it was prior to its removal. If the brush is worn down to approximately 1/2" (12.7 mm), the spring will no longer exert pressure and they must be

replaced.UseonlyidenticalDEWALTbrushes.Useofthe correctgradeofbrushisessentialforproperoperation

Controls

Your compound miter saw has several main controls, which will be discussed briefly here. For more information on these controls, see the respective sections later in the manual.

MITER CONTROL (FIG. 5, 10)

The miter lock lever (J)and miter latch (K)allows you to miter your saw 50° left and right. To miter the saw, unlock miter lock lever (J) by pulling upward, squeeze the detent trigger (K) and set the miter angle desired on the miter scale. Lock miter lock handle by pressing downward. Override the detent trigger by rotating knob (Fig. 10, V).

FIG.10

TRIGGER SWITCH (FIG. 2)

The trigger switch turns your saw on and off. A hole is provided in the trigger for insertion of a padlock to secure

the saw.

BEVEL LOCK (FIG. 7, 8)

The bevel lock knob (L) allows you to bevel the saw 48° left or right. To loosen the handle and adjust the bevel setting, turn the handle counterclockwise, the saw head bevels easily to the left or to the right once the 0° bevel override knob (S) is pulled. To tighten, turn the handle clockwise. Bevel degree markings are on the bottom front of the saw arm (Fig. 7, M).

0° BEVEL OVERRIDE (FIG. 8) The bevel stop override (S)allows you to bevel the saw to the

right past the 0° mark. The saw will automatically stop at 0° when brought up from

the left. To move past 0°to the right, pull the bevel stop knob. The stop knob can be locked out by pulling the knob out and rotating it 180°.

45° BEVEL STOP OVERRIDES (FIG. 8}

The bevel stop overrides (N) are held secure with their attachment screw to prevent inadvertent movement. Use the

bit on the blade wrench to loosen the attachment screw. This allows the slides, to be pulled outward and the saw head to

pivot past the 45° mark. Be sure to retighten the attachment screw when finished.

33.9° BEVEL STOPS (FIG. 8)

The two pawls (P) are used to stop the saw head bevel setting at 33.9°. This setting is used primarily for cutting crown moldings laid flat on the table.

HEAD DOWNLOCK PIN (FIG. 8}

To lock the saw head in the down position, push the head down, push the pin (U) in and release the saw head. This will hold the saw head safely down for moving the saw from place to place. To release, press the saw head down and pull the pin out.

OPERATION

_WARNING: To reduce the risk of serious personal injury, turn off the tool and disconnect it from the

power source before attempting to move it, change

accessories or make any adjustments.

_WARNING: Always use eye protection. All users and bystanders must wear eye protection that conforms to ANSI

Z87.1 (CAN/CSA Z94.3).

Plug the saw into any household 60 Hz power source. Refer to the nameplate for voltage. Be sure the cord will not interfere with your work.

SWITCH

To turn the saw on, depress the trigger switch. To turn the tool off, release the switch. Allow the blade to spin up to full operating rpm before making the cut. Release the trigger switch and allow the brake to stop the blade before raising the saw head. There is no provision for locking the switch on, but a hole is provided in the trigger for insertion of a padlock

to lock the saw off.

CUTTING WITH YOUR SAW NOTE: Although this saw will cut wood and many non-

ferrous materials, we will limit our discussion to the cutting of wood only. The same guidelines apply to the other materials. DO NOT CUT FERROUS (IRON AND STEEL)

MATERIALS OR MASONRY WITH THIS SAW. Do not use any abrasive blades.

CROSSCUTS

Cutting of multiple pieces is not recommended but can be done safely by ensuring that each piece is held firmly against the table and fence. A crosscut is made by cutting wood across the grain at any angle. A straight crosscut is made with the miter arm at the zero degree position. Set the miter arm at zero, hold the wood on the table and firmly against the fence. Turn on the saw by squeezing the trigger.

CAUTION: Always use a work clamp to maintain control

and reduce the risk of workpiece damage and personal

injury. When the saw comes up to speed (about 1 second) lower the

arm smoothly and slowlyto cut through the wood. Let the blade come to afullstop before raising arm.

Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often 45° for making corners, but can be set anywhere from zero to 50°leftor right. After selecting the desired miter angle, be sure to lock miter lock lever. Make

the cut as described above. To cut through an existing pencil line on a piece of wood,

match the angle as close as possible. Cut the wood a little too long and measure from the pencil line to the cut edge

to determine which direction to adjust the miter angle and recut. This will take some practice, but it isa commonly used technique.

BEVEL CUTS

A bevel cut is a crosscut made with the saw blade at a bevel to the wood. Inorder to set the bevel, loosen the bevel

clamp knob and move the saw to the left as desired. (It is necessary to move the fence to allow clearance). Once the desired bevel angle has been set, tighten the bevel clamp knob firmly.

Bevel angles can be set from 48 ° right to 48° left and can be cut with the miter arm set between zero and 50° right or left. At some extreme angles, the right or left side fence might have to be removed. To remove the left or right fence,

unscrew the knobs several turns and slide the fence out.

QUALITY OF CUT

The smoothness of any cut depends on a number of variables. Things likematerial being cut, blade type, blade sharpness and rate of cut allcontribute to the quality of the cut.

When smoothest cuts are desired for molding and other precision work, a sharp (60 tooth carbide) blade and a slower, even cutting rate will produce the desired results.

Ensure that material does not creep while cutting, clamp it securely in place. Always let the blade come to a full stop before raising arm.

If small fibers of wood still split out at the rear of the workpiece, stick a piece of masking tape on the wood where the cut will be made. Saw through the tape and carefully remove tape when finished.

Forvariedcuttingapplications,refertothelistofrecommended sawbladesforyoursawandselecttheonethatbestfitsyour needs.RefertoSaw Blades under Optional Accessories.

BODY AND HAND POSITION (FIG. 11)

Proper positioning of your body and hands when operating the miter saw will make cutting easier, more accurate and safer. Never place hands near cutting area. Place hands no closer than 6" (152 ram) from the blade. Hold the workpiece tightly to the table and the fence when cutting. Keep hands in position until the trigger has been released and the blade has completely stopped. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT YOU

CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS

ARMS, AS SHOWN IN FIGURE 11A.

Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm left and right, follow it and stand slightly to the side of the saw blade. Sight through the guard louvers when following a pencil line.

CLAMPING THE WORKPIECE

_WARNING: To reduce the risk of serious personal

injury, turn off the tool and disconnect it from the power source before attempting to move it, change accessories or make any adjustments.

i_WARNING: A workpiece that is clamped, balanced and

secure before a cut may become unbalanced after a cut is

completed. An unbalanced load may tip the saw or anything the saw is attached to, such as a table or workbench.

When making a cut that may become unbalanced, properly support the workpiece and ensure the saw is firmly bolted to a stable surface. Personal injury may occur.

i_WARNING: The clamp foot must remain clamped above

the base of the saw whenever the clamp is used. Always

clamp the workpiece to the base of the saw-not to any other part of the work area. Ensure the clamp foot is not clamped

on the edge of the base of the saw.

A CAUTION: Always use a work clamp to maintain control

and reduce the risk of workpiece damage and personal

injury.

Ifyou cannot secure the workpiece on the table and against

the fence by hand, (irregular shape, etc.) or your hand would

be less than 6" (152 ram) from the blade, a clamp or other

fixture must be used.

For best results use the DW7082 clamp made for use with

your saw. It is available for purchase at your local retailer or

DEWALTservice center.

Other aids such as spring clamps, bar clamps or C-clamps

may be appropriate for certain sizes and shapes of material.

Use care in selecting and placing these clamps. Take time to

make a dry run before making the cut. The left or right fence will slide from side to side to aid in clamping.

FIG. 11

FIG. 12

FIG. 11A

PROPER CUT

IMPROPER CUT

TO INSTALL CLAMP (SOLD SEPARATELY}

1. Insert it into the hole behind the fence. The clamp should be facing toward the back of the miter saw. The groove on the clamp rod should be fully inserted into the base. Ensure this groove is fully inserted into the base of the miter saw. If the groove is visible, the clamp will not be

secure.

2. Rotate the clamp 180° toward the front of the miter saw.

3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly clamp the workpiece.

NOTE: Place the clamp on the opposite side of the base when beveling. ALWAYS MAKE DRY RUNS (UNPOWERED)

BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE CLAMP DOES NOT INTERFERE WITH THE ACTION OF THE SAW OR GUARDS.

SUPPORT FOR LONG PIECES J_WARNING: To reduce the risk of serious personal

injury, turn off the tool and disconnect R from the

power source before attempting to move it, change

accessories or make any adjustments.

ALWAYS SUPPORT LONG PIECES. Never use another person as a substitute for a table

extension; as additional support for a workpiece that is longer or wider than the basic miter saw table or to help feed, support or pull the workpiece.

For best results, use the DW7080 extension work support or the DWX723, DWX724 or DWX725B miter saw stand to

extend the table width of your saw. These are available from your dealer at extra cost.

Support long workpieces using any convenient means such as sawhorses or similar devices to keep the ends from dropping.

CUTTING PICTURE FRAMES, SHADOW BOXES AND OTHER FOUR-SIDED PROJECTS

To best understand how to make the items listed here, we suggest that you try a few simple projects using scrap wood until you develop a "FEEL" for your saw.

Your saw is the perfect tool for mitering corners like the one shown in Figure 13. Sketch A in Figure 12 shows a joint made by using the bevel adjustment to bevel the edges of

the two boards at 45° each to produce a 90° corner. For this joint the miter arm was locked in the zero position and the bevel adjustment was locked at 45°. The wood was positioned with the broad flat side against the table and the narrow edge against the fence. The cut could also be made

by mitering right and left with the broad surface against the fence.

FIG. 14

ANGLE "A"

CUTTING TRIM MOLDING AND OTHER FRAMES Sketch B in Figure 12 shows a joint made by setting the miter arm at 45° to miter the two

boards to form a 90° corner. To make this type of joint, set the bevel adjustment to zero and the miter arm to 45 °. Once again, position the wood with the broad flat side on the table and the narrow edge against the fence.

The two sketches in Figure 12 are for four side objects only. As the number of sides changes, so do the miter and bevel angles. The chart below gives

the proper angles for a variety of shapes.

- EXAMPLES-

NO. SIDES ANGLE MITER OR BEVEL

4 45°

5 36° 6 30°

7 25.7 ° 8 22.5 °

9 20°

10 18°

(The chart assumes that all sides are of equal length.) For a shape that is not shown in the chart, use the following formula. 180° divided by the number of sides equals the miter (if the material is cut vertically) or bevel angle (ifthe material is cut laying flat).

CUTTING COMPOUND MITERS

A compound miter is a cut made using a miter angle and a bevel angle at the same time. This is the type of cut used to make frames or boxes with slanting sides like the one shown

in Figure 14. NOTE: If the cutting angle varies from cut to cut, check that the bevel clamp knob and the

miter lock knob are securely tightened. These knobs must be tightened after making any changes in bevel or miter.

The chart (Table 1) will assist you in selecting the proper bevel and miter settings for

common compound miter cuts. To use the chart, select the desired angle "A" (Figure 14) of your project and locate that angle on the appropriate arc in the chart. From that point follow the chart straight down to find the correct bevel angle and straight across to find the correct miter angle.

Set your saw to the prescribed angles and make a few trial cuts. Practice fitting the cut pieces together until you develop a feel for this procedure and feel comfortable with it.

Example: To make a four-sided box with 26° exterior angles (Angle A, Figure 14), use the upper right arc. Find 26° on the arc scale. Follow the horizontal intersecting line to either side

to get miter angle setting on saw (42°). Likewise, follow the vertical intersecting line to the top or bottom to get the bevel angle setting on the saw (18°). Always try cuts on a few scrap

pieces of wood to verify settings on saw.

VERNIER SCALE Your saw is equipped with a vernier scale for added precision. The vernier scale allows you

to accurately set miter angles to the nearest 1/4°. To use the vernier scale follow the steps listed below.

(As an example, let's assume that the angle you want to miter is 24-1/4 ° right).

1. Turn off miter saw.

2. Set the miter angle to the nearest whole degree desired by aligning the center mark in the vernier scale, shown in Figure 15, with the whole degree number etched in the miter scale. Examine Figure 16 closely; the setting shown is 24° right miter.

3. To set the additional 1/4°, squeeze the miter arm lock and carefully move the arm to the RIGHT until the 1/4° vernier mark aligns with the CLOSEST degree mark on the miter scale. In our example, the closest degree mark on the miter scale happens to be 25°. Figure 16 shows a setting of 24-1/4 ° right miter.

For settings that require partial degrees (1/4, 1/2, 3/4 °) align the desired vernier mark with the CLOSEST degree mark on the miter scale, as described below (The plastic vernier plate is inscribed with marks for 1/4, 1/2, 3/4 and 1°. Only the 1/2° and the 1° are numerically labeled.)

WHEN MITERING TO THE RIGHT To increase the miter angle when mitering to the right, move the arm to align the appropriate

vernier mark with the closest mark on the miter scale to the right. To decrease the miter angle when mitering to the right, move the arm to align the appropriate vernier mark with the closest

mark on the miter scale to the left. WHEN MITERING TO THE LEFT

To increase the miter angle when mitering to the left, move the arm to align the appropriate vernier mark with the closest mark on the miter scale to the left. To decrease the miter

angle when mitering to the left, move the arm to align the appropriate vernier mark with the closest mark on the miter scale to the right.

CUTTING BASE MOLDING

ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS.

Straight 90° cuts:

Position the wood against the fence and hold it in place as shown in Figure 17. Turn on the saw, allow the blade to reach full speed and lower the arm smoothly through

the cut.

CUTTING CROWN MOLDING

Your miter saw is better suited to the task of cutting crown molding than any tool made. In order to fit properly, crown molding must be compound mitered with extreme

accuracy. The two flat surfaces on a given piece of crown molding are at angles that, when added together, equal exactly 90°.

Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52° and a bottom

rear angle (the part that fits flat against the wall) of 38°. Your miter saw has special pre-set miter latch points at

31.62 ° left and right for cutting crown molding at the proper angle and bevel stop pawls at 33.9 ° left and right. There is also a mark on the bevel scale at 33.9 °.

The Bevel Setting/Type of Cut chart gives the proper settings for cutting crown molding. (The numbers for the miter and bevel settings are very precise and are not easy to accurately set on your saw.) Since most rooms do not have angles of precisely 90°, you will have to fine tune your settings anyway.

When setting bevel and miter angles for all compound miters, remember that:

The angles presented for crown moldings are very precise and difficult to set exactly. Since they can easily shift slightly and very few rooms have exactly square corners, all settings should be tested on scrap molding.

PRETESTING WITH SCRAP MATERIAL IS

EXTREMELY IMPORTANT!

ALTERNATIVE METHOD FOR CUTTING CROWN

MOLDING

Place the molding on the table at an angle between the fence and the saw table, as shown in Figure 18A. Use of the crown molding fence accessory (DW7084) is highly recommended because of its degree of accuracy and convenience. The crown molding fence accessory is available for purchase from your local dealer.

The advantage to cutting crown molding using this method

is that no bevel cut is required. Minute changes in the miter angle can be made without affecting the bevel angle. This

way, when corners other than 90° are encountered, the saw

can be quickly and easily adjusted for them. Use the crown molding fence accessory to maintain the angle at which the molding will be on the wall.

INSTRUCTIONS FOR CUTTING CROWN MOLDING ANGLED BETWEEN THE FENCE AND BASE OF THE SAW FOR ALL CUTS:

1. Angle the molding so the bottom of the molding (part which goes against the wall when installed) is against the fence and the top of the molding is resting on the base of the saw, as shown in Figure 18A.

2. The angled "flats" on the back of the molding must rest squarely on the fence and base of the saw.

Special Cuts

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE FENCE.

ALUMINUM cu'n'ING

ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM. These are

available at your local DEWALT retailer or DEiWALTservice center. Certain workpieces, due to their size, shape or surface finish, may require the use of a clamp or fixture to prevent movement during the cut. Position the material so

that you will be cutting the thinnest cross section, as shown in Figure 19. Figure 19A illustrates the wrong way to cut

these extrusions. Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax directly to the saw

blade before cutting. Never apply stick wax to a moving blade.

The wax, available at most hardware stores and industrial mill

supply houses, provides proper lubrication and keeps chips from adhering to the blade.

Be sure to properly secure workpiece. Refer to Saw Blades under Optional Accessories for

correct saw blade.

BOWED MATERIAL

When cutting bowed material always position it as shown in Figure 20 and never like that shown in Figure 20A. Positioning the material incorrectly will cause it to pinch the blade near the completion of the cut.

CUTTING PLASTIC PIPE OR OTHER ROUND MATERIAL

Plastic pipe can be easily cut with your saw. It should be cut

just like wood and CLAMPED OR HELD FIRMLY TO THE

FENCE TO KEEP IT FROM ROLLING. This is extremely important when making angle cuts.

CUTTING LARGE MATERIAL Occasionally you will encounter a piece of wood a little too

large to fit beneath the blade guard. If this occurs, simply place your right thumb on the upper side of the guard and roll the guard up just enough to clear the workpiece, as shown in Figure 21. Release the lower blade guard before turning the saw on and beginning the cut. Avoid doinAvoid doing this as much as possible, but if need be, the saw

will operate properly and make the bigger cut. NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN

OPERATING THIS SAW. SPECIAL SET-UP FOR WIDE CROSSCUTS

Your saw can cut very wide [up to 10" (406 mm)] workpieces when a special set up is used. To set the saw up for these workpieces, follow these steps:

1. Remove both left and right sliding fences from the saw and set aside. To remove them, unscrew the fence

knobs several turns and slide each fence outward. Adjust and lock the miter control so that it is at 0° miter.

FIG. 20A

2. Make a platform using a piece of 1.5 inch (38 mm) thick particleboard or similar flat strong 1.5" (38 mm) thick

wood to the dimensions: 10" x 24" (254 x 610 mm). The platform must be flat otherwise the material could move

during cutting and cause injury.

3. Mount the 10" x 24" (254 x 610 mm) platform to the saw using 4 three-inch (76 mm) long wood screws through the holes in the base fence (Fig. 22). Four screws must be used to properly secure the material. When the special set up is used, the platform will be cut into two pieces. Ensure the screws are tightened properly otherwise material could loosen and cause injury. Ensure the platform is firmly flat on the table, against the fence, and centered evenly from left to right.

_WARNING: Ensure the saw is mounted firmly to a stable

flat surface. Failure to do so could cause the saw to be unstable and fall causing personal injury.

4. Place the workpiece to be cut on top of the platform mounted to the table. Ensure the workpiece is firmly against the backfence (Fig. 22).

5. Secure the material before cutting. Cut slowly through the material. Failure to clamp securely or cut slowly could result in the material coming loose and causing injury.

After several cuts are made at various miter angles other than 0°, the platform may weaken and not properly support the work. Install a new, unused platform to the saw after presetting the desired miter angle.

_, CAUTION: Continued use of aplatform with several kerfs

may cause loss of material control and possible injury.

Removing and Replacing Belt

The belt is designed to last the life of the tool. However, abuse of the tool could cause the belt to fail.

If the blade does not turn when the motor is running, the belt has failed. To inspect or replace the belt, remove the belt cover screws. Remove the belt cover. Inspect the ribs of the belt for wear or failure. Check belt tension by squeezing the belt as shown in Figure 23. The belt halves should almost touch when squeezing firmly with the thumb and index finger.

To adjust the tension, loosen, but do not remove, the four Phillips head screws shown. Then rotate the set screw on the top of the motor plate casting until the proper tension is achieved. Tighten the four screws securely and replace the

belt cover. NOTE: Over tightening the belt will cause premature motor

failure.

MAINTENANCE

DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic guard. The polycarbonate material used in the guard is subject to attack by certain

chemicals.

1. All bearings are sealed. They are lubricated for life and need no further maintenance.

2. Periodically clean all dust and wood chips from around AND UNDER the base and the rotary table. Even though slots are provided to allow debris to pass through, some

dust will accumulate.

3. The brushes are designed to give you several years of use. If they ever need replacement follow the

instructions under Brushes or return the tool to the nearest service center for repair.
