IMPORTANT SAFETY INSTRUCTIONS
WARNING: Read all instructions before operating product. Failure to follow
all instructions listed below may result in electric shock, fire 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.

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

IMPORTANT SAFETY INSTRUCTIONS
Changing or Installing a New Saw Blade (Fig. 5, 6)
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.
CAUTION:
• Never depress the spindle lock button while the blade is under power or coasting. • Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product
with this miter saw.
Removing the Blade 1. Unplug the saw. 2. Raise the arm to the upper position and raise the lower guard as far as possible. 3. Loosen, but do not remove guard bracket screw until the bracket can be raised far
enough to access the blade screw. Lower guard will remain raised due to the position of the guard bracket screw.
4. Depress the spindle lock button (Fig. 3) while carefully rotating the saw blade by hand
until the lock engages.
Recommended accessories for use with your tool are available for purchase from your local dealer or authorized service center. If you need assistance in locating any accessory for your tool, please contact DEWALT Industrial Tool Co., 701 East Joppa Road, Baltimore,
MD 21286, call 1-800-4-DEWALT (1-800-433-9258) or visit our website www.dewalt.com.
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.

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 DEWALT service center.

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 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.
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 approximately1/2"(12.7 mm),thespringwillnolongerexert pressure and they must be replaced. Use only identical DEWALT brushes. Use of the correct grade of brush is
essential for proper operation of electric brake. New brush assemblies are available at DEWALT service centers. The 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. While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON. HOLD BY HAND ONLY.
