IMPORTANT SAFETY INSTRUCTIONS
WARNING: Read all instructions before operating product. Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury.
READ ALL INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate layers of electrical insulation or one double thickness of insulation between you and the tool’s electrical system. Tools built with this insulation system are not intended to be grounded. As a result, your tool is equipped with a two prong plug which permits you to use extension cords without concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety precautions when operating this tool. The insulation system is for added protection against injury resulting from a possible electrical insulation failure within the tool.
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
This miter saw accepts the DEWALT worklight and laser attachments.
WARNING: 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 PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or
other jewelry to get caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair. Air vents may cover moving parts and should also be avoided.
ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
ANSI Z87.1 eye protection (CAN/CSA Z94.3)
• ANSI S12.6 (S3.19) hearing protection
• NIOSH/OSHA/MSHA respiratory protection
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 all times. 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 in good 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 gague. The smaller the gauge number, the heavier the cord.

NOT USE THE MACHINE WHEN YOU ARE TIRED OR UNDER THE INFLUENCE OF DRUGS or ALCOHOL. A moment of inattention while operating power tools may
result in injury.
Additional Safety Rules For Miter Saws
WARNING: Do not allow familiarity (gained from frequent use of your saw) to replace
safety rules. Always remember that a careless fraction of a second is sufficient to inflict severe injury.
DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury.
OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not thoroughly familiar with the operation of this machine. Knowledge is safety.
STABILITY. Make sure the miter saw is placed on a secure supporting surface and does not slip or move during use. If the mobility kit is installed, raise the moveable caster(s) so saw is in its stationary position.
FOLLOW ALL WIRING CODES and recommended electrical connections to prevent shock or electrocution. Protect electric supply line with at least a 15 ampere time-delay fuse or a circuit breaker.”
MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should point in the direction of rotation as marked on the saw.
TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation. Loose clamps can cause parts or the workpiece to be thrown at high speeds.
BE SURE all blade and blade clamps are clean, recessed sides of blade clamps are against blade and arbor screw is tightened securely. Loose or improper blade clamping may result in damage to the saw and possible personal injury.
ALWAYS USE A SHARP BLADE. Check the blade to see if it runs true and is free from vibration. A dull or a vibrating blade can cause damage to the machine and/or serious injury.
DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED VOLTAGE for the saw. Overheating, damage to the tool and personal injury may occur.
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 prior to 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 fly off the blade at high speeds causing serious injury.
DO NOT USE ABRASIVE 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 the machine 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.

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 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: To prevent 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.

ADJUSTMENTS
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 accept as written in laser adjustment instructions.
NOTE: Your miter saw is fully and accurately adjusted at the factory at the time of manufacture. If readjustment due to shipping and handling or any other reason is required, follow the steps below to adjust your saw.
Once made, these adjustments should remain accurate. Take a little time now to follow these directions carefully to maintain the accuracy of which your saw is capable.
MITER SCALE ADJUSTMENT
Place a square against the saw’s fence and blade, as shown in Figure 7. (Do not touch the tips of the blade teeth with the square. To do so will cause an inaccurate measurement.) Unlock miter lock lever (see Fig. 8) and swing the miter arm until the miter detent locks it at the 0˚ miter position. Do not lock miter lock lever. If the saw blade is not exactly perpendicular to the fence, loosen the three screws that hold the miter scale to the base (shown in Fig. 8) and move the scale/miter arm assembly left or right until the blade is perpendicular to the fence, as measured with the square. Retighten the three screws. Pay no attention to the reading of the miter pointer at this point.
MITER POINTER ADJUSTMENT
Unlock miter lock lever and squeeze the miter detent to move the miter arm to the zero position, as shown in Figure 8. Unlock the miter lock lever to allow the miter detent to snap into place as you rotate the miter arm past zero. Observe the pointer and miter scale through the viewing opening shown in Figure 9. If the pointer does not indicate exactly zero, loosen the pointer screw, adjust the pointer to 0˚ and retighten.
BEVEL SQUARE TO TABLE
To align the blade square to the rotary table, lock the arm in the down position. Place a square against the blade taking care to not have the square on top of a tooth, as shown in Figure 10B. Loosen the Bevel Clamp Knob so that you can move the Bevel Arm. Move the Bevel Arm as necessary so that the blade is at 0° bevel to the table. If the Bevel Arm needs adjustment, loosen the lock nut on the right side Bevel Stop as shown in Figure 11, and adjust the stop screw as necessary. Hold the stop screw in place and tighten the lock nut.
BEVEL POINTER
If the bevel pointer does not indicate zero, loosen the screw that holds it in place and move the pointer as necessary.
Suggestion: For accuracy, set the top edge so that it aligns with zero.
BEVEL STOP
To set the 45° bevel stop shown in Figure 12, first loosen the left side fence clamping knob and slide the left side fence as far as it will go to the left. Move the arm to the left until it stops on the left bevel stop screw. If the bevel pointer does not indicate exactly 45°, loosen the left side bevel stop lock nut and turn the screw downwards. Move the arm to the left and tighten the bevel clamp knob firmly

when the bevel pointer indicates exactly 45°. Adjust the left side bevel stop screw upwards until it firmly touches the bevel stop. Retighten the nut while holding the screw from turning.
To achieve 3° right bevel or 48° left bevel, the stop screws must be adjusted to allow the arm to move to the desired location. The bevel stops will need readjustment to the zero and 45° positions after cuts are made.
FENCE ADJUSTMENT
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 accept as written in laser adjustment instructions.
To bevel UP TO 48° left, the left side of the fence can be adjusted to the left to provide clearance. To adjust the fence, loosen the knob shown in Figure 13 and slide the fence to the left. 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 to the right.
GUARD ACTUATION AND VISIBILITY
CAUTION: Pinch Hazard. To reduce 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 will require that you manually raise the guard. See section on Cutting Base Molding Up to 3.5" (88.9 mm) High (page 11). The front section of the guard is louvered 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.
AUTOMATIC ELECTRIC BRAKE
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.
If a delay or “skipping” occurs, turn the saw on and off 4 or 5 times. If the condition persists, have the tool serviced by an authorized D
EWALT service center.

Always be sure the blade has stopped before removing it from the kerf. The brake is not a substitute for guards or for ensuring your own safety by giving the saw your complete attention.
MITER LOCK ADJUSTMENT (FIG. 15)
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 in the 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.
NOTE: Some models may have a set screw as shown in Figure 15. Using a 3/32 hex wrench, loosen the set screw on the pivot pin. Tighten set screw after adjustment is complete.
Brushes
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 accept as written in laser adjustment instructions.
Inspect carbon brushes regularly by unplugging tool, removing the motor end cap (Fig. 2), lift the brush spring and withdraw the 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. Carbon brushes have varying symbols stamped into their sides, and 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. Use only identical
EWALT brushes. Use of the correct grade of brush is
D essential for proper operation of electric brake. New brush assemblies are available at D tool should be allowed to “run in” (run at no load) for 10 minutes before use to seat new brushes. The electric brake may be erratic in operation until the brushes are properly seated (worn in). Always replace the brush inspection cap after inspection or servicing the brushes.

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 accept as written in laser adjustment instructions.
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 shown in Figure 14. To turn the tool off, release the switch. 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 switch shown in Figure 14.
When the saw comes up to speed (about 1 second) lower the arm smoothly and slowly to cut through the wood. Let the blade come to a full stop before raising arm.
CAUTION: Always use a work clamp to maintain
control and reduce the risk of workpiece damage and personal injury.
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° left or right. After selecting the desired miter angle, be sure to tighten the 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 is a commonly used technique.
8
BEVEL CUTS
A bevel cut is a crosscut made with the saw blade at a bevel to the wood. In order to set the bevel, loosen the bevel clamp knob and move the saw to the left as desired.
(It is necessary to move the left side of 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 3° right to 48° left and can
be cut with the miter arm set between zero and 50° right or left. Ensure the fence has been adjusted properly. When cutting left bevel, or right miter compound cuts, it will be necessary to remove the adjustable fence.
QUALITY OF CUT
The smoothness of any cut depends on a number of variables. Things like material being cut, blade type, blade sharpness and rate of cut all contribute to the quality of the cut.
When smoothest cuts are desired for molding and other precision work, a sharp (60–80 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, apply a piece of masking tape on the wood where the cut will be made. Saw through the tape and carefully remove tape when the cut is finished. For varied cutting applications, refer to the list of recommended saw blades for your saw and select the one that best fits your needs (Page 4).
BODY AND HAND POSITION (FIG. 16)
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 mm) 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 HANDS, AS SHOWN IN FIGURE 15A.
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.

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.
English
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.
CAUTION: Always use a work clamp to maintain
control and reduce the risk of workpiece damage and personal injury.
If you 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 mm) from the blade, a clamp or other fixture should be used.
For best results use the DW7082 clamp made for use with your saw. It is available through your local retailer or
EWALT service center at extra cost.
D 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 fence will slide from side to side to aid in clamping.
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 180º 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.
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.

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 17. Sketch A in Figure 17 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.
CUTTING TRIM MOLDING AND OTHER FRAMES
Sketch B in Figure 17 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 17 are for four sided 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. 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 or bevel angle.

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 18.
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 shown on page 16 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 19) 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 4 sided box with 26° exterior angles (Angle A, Figure 19), 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.
MITER SCALE
The scale is used when calculating angles. To calculate the proper miter angle, divide 180° by the number of sides of the box or frame. Refer to the chart on page 11 for some examples.
VERNIER SCALE (FIG. 23, 24)
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° (15 minutes). 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 23, with the whole degree number etched in
FIG. 23
CENTER MARK ON VERNIER SCALE ALIGNS WITH

DEGREE MARK ON MITER SCALE (24-1/4° RIGHT MITER)
FIG. 25
the miter scale. Examine Figure 23 closely; the setting shown is 24º 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 24 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 above. (The plastic vernier plate is inscribed with marks for 1/4, 1/2, 3/4 and 1°. Only the 1/2° is 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.

Material up to 3.5" (88.9 mm) can be cut as described above. For wider boards [up to 4.25" (107.95 mm)] several minor concessions must be made.
When cutting a board between 3.5" (88.9 mm) and 4.25" (107.95 mm) in width the roller on the tip of the guard could

hang up on the workpiece. 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 28. Once you have cleared the workpiece, you can release the guard and it will continue to open as the cut progresses.
When mitering to the right side of a base molding wider

than 3.5" (88.9 mm) standing vertically against the fence as in Figure 25, the saw can only cut through the board up to 1 inch from the end of the board. Trying to cut more than an inch will cause the saw’s gear case to interfere with the workpiece. If you want to cut base molding between 3-1/2" (88.9 mm) and 4.25" (107.95 mm) wide vertically follow the directions below.

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 detent points at
31.62° left and right for cutting crown molding at the proper angle (Fig. 27). There is also a mark on the Bevel scale at 33.85°.
The chart below 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.

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
EXTREME LY 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 30. 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 at extra cost 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 (DW7084) 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 30.
2. The angled “flats” on the back of the molding must rest squarely on the fence and base of the saw.

ALUMINUM CUTTING
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM. These are available at your local DEWALT retailer or DEWALT service 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 31. Figure 32 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.
English
13
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 page 4 correct saw blade.
BOWED MATERIAL
When cutting bowed material always position it as shown
English
in Figure 33 and never like that shown in Figure 34. 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. A little extra height can be gained by rolling the guard up out of the way, as shown in Figure 28. Avoid 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.
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. To replace the brushes refer to Brushes on page 8 or return the tool to the nearest service center for repair. A list of service center locations is packed with your tool.
