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

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

operating the miter saw.

This miter saw accepts the D

• 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.

EWALT worklight and laser attachments.

• 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" (152.4 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 gauge. The smaller the gauge number, the heavier the cord.

• STAY ALERT, WATCH WHAT YOU ARE DOING, AND USE COMMON SENSE. DO

NOT USE THE MACHINE WHEN YOU ARE TIRED OR UNDER THE INFLUENCE OF DRUGS 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, use only zero-degree or negative hook angles when using carbide-tipped blades. 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 [within 6" (152.4 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.

• PROPERLY SUPPORT LONG OR WIDE WORKPIECES. Loss of control of the workpiece can cause injury.

• NEVER cross arms in front of blade while using tool. Always make a dry run (unpowered) before making a finish cut so that you can check the path of the blade or severe personal injury may result.

Familiarization

Your miter saw is fully assembled in the car ton. Open the box and slide the saw out, as shown in Figure 1.

Place the saw on a smooth, flat surface such as a workbench or strong table.

Examine the two figures on Page 7 to become familiar with the saw and its various parts. The section on adjustments will refer to these terms and you must know what and where the parts are.

CAUTION: Risk of personal injury. Keep thumb

underneath handle when pulling handle down otherwise thumb may be pinched between handle and moving lower guard.

The handle is placed close to the guard for special cuts.

Press down lightly on the operating handle and pull out the lock down pin. 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.

FIG. 1

FIG. 2

Bench Mounting

Holes are provided in all 4 feet to facilitate bench mounting, as shown in Figure 4. (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: 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.

IMPORTANT SAFETY INSTRUCTIONS

NOTE: Your miter saw is fully ande ad 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 (FIG. 5)

Place a square against the saw’s fence and blade, as shown. (Do not touch the tips of the blade teeth with the square. To do so will cause an inaccurate measure ment.) Loosen the miter lock handle and swing the miter arm until the miter latch locks it at the 0 miter position. Do not tighten the lock handle. If the saw blade is not exactly perpendicular to the fence, loosen the four screws that hold the miter scale to the base and move the scale left or right until the blade is perpendicular to the fence, as measured with the square. Retighten the four screws. Pay no attention to the reading of the miter pointer at this time.

MITER POINTER ADJUSTMENT (FIG. 6)

Loosen the miter lock handle to move the miter arm to the zero position. With the miter lock handle loose allow the miter latch to snap into place as you rotate the miter arm to zero. Observe the pointer and miter scale shown in Figure 6. If the pointer does not indicate exactly zero, loosen the screw holding the pointer in place, reposition the pointer and tighten the screw.

BEVEL SQUARE TO TABLE ADJUSTMENT (FIG. 8)

To align the blade square to the table, lock the arm in the down position. Place a square against the blade and table taking care to have the square not touch a blade tooth. Loosen the bevel lock handle and ensure the bevel latch has firmly snapped into place at 0º. If the saw blade is not exactly perpendicular to the table, loosen the three nuts which hold the bevel detent plates to the table. Adjust the center nut to allow slight drag between it and the table. Gently tap the motor or the belt cover to move the upper assembly until the blade is square to the table. Tighten the center nut. The 45 bevel stops require adjustment after the bevel square to table adjustment is complete.

BEVEL POINTER (FIG. 8)

If the bevel pointer does not indicate zero, loosen the screw that holds it in place and move it as necessary.

BEVEL STOP 45º RIGHT AND LEFT ADJUSTMENT (FIG. 8)

Your saw has two 45º bevel adjustments, one for the right, and one for the left. The procedure is the same for each.

To align the 45º stops, lock the arm in the down position. Place a speed square against the blade and table taking care to have the square not touch a blade tooth. Loosen the bevel lock lever and ensure the bevel latch has firmly snapped into place at 45º. If the saw blade is not 45º to the table, loosen the nut which holds the 45 bevel latch plate to the table. Rotate the adjustment screw counterclockwise one or two turns so that the blade is less than 45º to the table. Turn the adjustment screw clockwise until the blade is 45º to the table. Tighten the lock nut.

FENCE ADJUSTMENT (FIG. 9)

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.

In order that the saw can bevel to a full 48º left or right, one of the fences can be adjusted to provide clearance. To adjust the fences, loosen a plastic knob 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 max imum 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 you notice that it is becoming clogged, use a stick or some low pressure air to clear the guide groove.

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.

GUARD ACTUATION AND VISIBILITY

CAUTION: Risk of personal injury. Keep thumb

underneath handle when pulling handle down otherwise thumb may be pinched between handle and moving lower guard. The handle is placed close to the guard for special cuts.

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 UN LESS THE SAW IS TURNED OFF.

NOTE: Certain special cuts of large material will require that you manually raise the guard. See Page 13.

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.

English

KERF PLATE ADJUSTMENT

To adjust the kerf plates, loosen the screws holding the kerf plates in place. Adjust so that the kerf plates are as close as possible without interfering with the blade’s movement.

RAIL GUIDE ADJUSTMENT

Periodically check the rails for any play or clearance. The

English

right rail can be adjusted with the set screw shown in Figure 4. To reduce clearance, use a 4 mm hex wrench and rotate the set screw clockwise gradually while sliding the saw head back and forth. Adjust the clearance to be as small as possible without causing any slide resistance.

MITER LOCK ADJUSTMENT

The miter lock rod should be adjusted if the table of the saw can be moved when the miter lock is locked down. To adjust the miter lock handle, put the miter lock handle in the up, unlocked position. Using a 13 mm open end wrench, loosen the lock nut on the miter lock rod (Fig. 10). Using a slotted screwdriver, tighten the miter lock rod by turning it clockwise as shown in Figure 10. Turn the lock rod until it is snug, then turn counterclockwise one turn. To ensure the miter lock handle is functioning properly, re-lock the miter lock to a non-detented measurement on the miter scale – for example, 34º – and ensure the table will not rotate. Tighten lock nut.

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. 4), 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 DEWALT brushes. Use of the correct grade of brush is essential for proper operation of electric brake. New brush assemblies are available at D 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 OTHER WISE LOCK THE TRIGGER SWITCH ON. HOLD BY HAND ONLY.

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 earlier in the manual.

MITER CONTROL (FIG. 7)

The miter adjustment/lock handle and detent trigger allows you to miter your saw to 60 left and 50 right. To miter the saw, lift the miter adjustment/lock handle, push the miter latch button and set the set the miter angle desired on the miter scale. Push down on the lock handle to lock the saw table in place.

TRIGGER SWITCH

The trigger switch (Fig. 4) turns your saw on and off. A hole is provided in the trigger for insertion of a padlock to secure the saw.

MITER LATCH OVERRIDE (FIG. 7)

The miter latch override allows your saw to override the common stop angles. Your saw has two miter latch override knobs, one on each side of the miter control. To override the common stop angles, rotate the miter latch knobs downward. The knobs will return to the off position automatically if the miter latch button is pushed.

BEVEL CONTROL (FIG. 8)

The bevel latch levers and bevel lock handle allow you to bevel the saw to 48º left and right. Your saw has two bevel latch levers, one on either side of the rear support housing. Only one needs to be used to move the bevel to either direction. The bevel lock handle is on top of the rear support housing. To bevel the saw, loosen the bevel lock handle. Lift one of the levers to approximately 45 º and set the bevel angle desired on the bevel scale. Two bevel scales are provided for convenience. Lock the bevel lock handle to lock the bevel in place. The bevel latch levers can be lifted vertically to override the common stop angles. The bevel lock handle is designed to have a limited rotation amount. The handle can be reoriented to compensate for normal wear. The bevel lock handle should be reoriented if the bevel of the saw can be moved when the bevel lock handle is tightened. To adjust the bevel lock handle, remove the screw in the center of the handle. Carefully

pry off the handle using a flat bladed screwdriver. Reorient and install the handle such that it will hold the bevel when tightened. Install and tighten screw.

FIG. 10A

SLIDE STOP (FIG. 10A)

The slide stop control positions your saws rails so that the largest possible verticle moldings can be cut. ALWAYS TIGHTEN THE RAIL LOCK KNOB WHEN USING THE SLIDE STOP TO PREVENT THE SLIDE SYSTEM FROM MOVING UNINTENTIONALLY

RAIL LOCK KNOB (FIG. 4)

The rail lock knob allows you to lock the saw head firmly to keep it from sliding on the rails. This is necessary when making certain cuts or when transporting the saw.

GROOVING STOP (FIG. 4)

The grooving stop allows for groove cutting. Flipping the lever toward the front of the saw and adjusting the thumbscrew changes the depth of the groove cut. Flipping the lever toward the rear of the saw bypasses the grooving stop.

HEAD DOWNLOCK PIN (FIG. 4)

To lock the saw head in the down position, push the head down, push the pin 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.

RAIL LOCK KNOB

SLIDE STOP

Operation

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

If the slide feature is not used, ensure the saw head is pushed back as far as possible and the rail lock knob is

tightened. This will prevent the saw from sliding along its rails as the workpiece is engaged.

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 mat erials. DO NOT CUT FERROUS (IRON AND

STEEL) MAT ERIALS 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. 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.

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 and lock the miter arm at zero, hold the wood firmly on the table and against the fence. With the rail lock knob tightened, turn on the saw by squeezing the trigger switch shown in Figure 4.

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.

When cutting anything larger than 4.4" (111.8 mm) [3" (76.2 mm) 45º miter] use an out-down-back motion with the rail lock knob loosened. Pull the saw out, toward you, lower the saw head down toward the workpiece, and slowly push the saw back to complete the cut. Do not allow the saw to contact the top of the workpiece while pulling out. The saw may run toward you, possibly causing personal injury or damage to the workpiece.

CAUTION: Always use a work clamp to maintain

control and reduce the risk of workpiece damage and personal injury.

NOTE: The rail lock knob shown in Figure 4 must be loose to allow the saw to slide along its rails.

Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often 45º for making corners, but can be set anywhere from left or right. Make the cut as described above.

When cutting wider workpieces wider than a 2 x 6 that are shorter in length, always place the longer side against the fence (Fig. 12).

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.

BEVEL CUTS

A bevel cut is a crosscut made with the saw blade at an angle to the wood. In order to set the bevel, loosen the bevel lock handle, lift the bevel latch lever, Figure 4, and move the saw to the left or right as desired. (It is necessary

FIG. 11

FIG. 12

to move the fence to allow clearance). Once the desired bevel angle has been set, tighten the bevel clamp handle firmly.

Bevel angles can be set from 48º right to 48º left and can be cut with the miter arm set between 50º right or 60º 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 fence adjustment knob several turns and slide the fence out.

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 tooth carbide) blade and a

FIG. 13A

PROPER CUT

FIG. 13B

IMPROPER CUTS

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.

English

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 5).

BODY AND HAND POSITION (FIG. 13A)

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

English

no closer than 6" (152.4 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 13B. 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 accept as written in laser adjustment instructions.

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.

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.

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" (152.4 mm) from the blade, a clamp or other fixture must be used.

For best results use the DW7082 clamp made for use with your saw. Another type of clamp may be supplied with your DW717. To purchase the DW7082 contact your local retailer or D

EWALT service 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. 14

FIG. 16

FIG. 15

ANGLE “A”

TO INSTALL CLAMP

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.

WARNING: The clamp foot must remain clamped above

SUPPORT FOR LONG PIECES

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.

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 to extend the table width of your saw. 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 14. Sketch A in Figure 15 shows a joint made by using the bevel adjustment to bevel the edges of the two boards at 45º each to produce a 90º corner. For this joint the miter arm was locked in the zero position and the bevel adjustment was locked at 45º. 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 14 shows a joint made by setting the miter arm at 45º to miter the two boards to form a 90º corner. To make this type of joint, set the bevel adjustment to zero and the miter arm to 45º. 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 15 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.

(The chart assumes that all sides are of equal length.) For a shape that is not shown in the chart, use the following formula. 180º divided by the number of sides equals the miter (if the material is cut vertically) or bevel angle (if the 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 16.

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 16) 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 26º exterior angles (Angle A, Figure 15), 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.

CUTTING BASE MOLDING

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

Straight 90º cuts: Position the wood against the fence and hold it in

place as shown in Figure 11. 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 other type 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 90º. Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52º and a bottom rear angle (the part that fits flat against the wall) of 38º.

Your miter saw has special pre-set miter latch points at

31.62º left and right for cutting crown molding at the proper

angle and bevel stop pawls at 33.85º left and right. There is also a mark on the Bevel scale at 33.85º.

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 90º, you will have to fine tune your settings anyway.

PRETESTING WITH SCRAP MATERIAL IS

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 18. 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 90º 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 18.

Special Cuts

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

ALUMINUM CUTTING

ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM. These are available at your local D 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 19. Figure 20 illustrates the wrong way to cut these extrusions. Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax cutting lubricant 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 Page 5 for correct saw blade.

BOWED MATERIAL

When cutting bowed material always position it as shown in Figure 21 and never like that shown in Figure 22. 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

EWALT retailer or DEWALT

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 23. 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.

SPECIAL SET-UP FOR WIDE CROSSCUTS

Your saw can cut very wide [up to 15.4 inch (391 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 degrees miter.

2. Remove backfence screws from right rear foot and install them into the right hand fence screw holes (FIG 25).

WARNING: Do not cut material using the special setup

without properly installing the backfence screws, otherwise the material will not be supported properly and may cause loss of control and possible injury.

3. Make a platform using a piece of 1.5 inch (38 mm) thick particleboard or similar flat strong 1.5 inch thick wood to the dimensions: 14.5" x 26" (368 x 660 mm). The platform must be flat otherwise the material could move during cutting and cause injury.

4. Mount the 14.5" x 26" platform to the saw using 4 three-inch long wood screws through the holes in the base fence (Fig. 24). 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.

5. Place the workpiece to be cut on top of the platform mounted to the table. Ensure the workpiece is firmly against the backfence screws (Fig. 25).

6. Secure the material before cutting. Cut slowly through the material using a out-down-and-back motion. 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 0º, the platform may weaken and not properly support

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 26. 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 on Page 9 or return the tool to the nearest service center for repair. Service center locations are packed with your tool.
