Important Safety Instructions

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

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

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

• 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.

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

• DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.

• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.

• MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.

• 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.

• WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or other jewelry to get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair.

• ALWAYS WEAR SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses have only impact resistant lenses, they are NOT safety glasses.

• SECURE WORK. Use clamps or vise when you cannot secure the workpiece on the table and against the fence by hand or when your hand

will be dangerously close to the blade (within 6”).

• DON’T OVERREACH. Keep proper footing and balance at all times.

• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories.

• DISCONNECT TOOLS before servicing; when changing accessories such as blades, bits, cutters, etc.

• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in OFF position before plugging in.

• USE RECOMMENDED ACCESSORIES. Consult the instruction manual for recommended accessories. The use of improper accessories may cause risk of injury to persons.

• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.

• CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function—check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. Do not use tool if switch does not turn it on and off.

• NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool until it comes to a complete stop.

• DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN GASEOUS OR EXPLOSIVE ATMOSPHERES. Motors in these tools may spark and ignite fumes.

• EXTENSION CORDS. Make sure your extension cord is in good condition. 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 gage. The smaller the gage number, the heavier the cord.

English

• DO NOT - Move either hand from saw or workpiece or raise arm until blade has stopped.

• DO NOT - Use without Kerf Plate or when kerf slot is wider than 3/8".

CAUTION: Wear appropriate personal hearing protection during use. Under some

conditions and duration of use, noise from this product may contribute to hearing loss.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding,

drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or

lay on the skin may promote absorption of harmful chemicals.

CAUTION: Do not connect unit to electrical power source until complete instructions

are read and understood.

For your convenience and safety, the following warning labels are on your miter saw.

ON MOTOR HOUSING: WARNING: FOR YOUR OWN SAFETY, READ INSTRUCTION MANUAL BEFORE

OPERATING SAW. WHEN SERVICING, USE ONLY IDENTICAL

REPLACEMENT PARTS. ALWAYS WEAR EYE PROTECTION. DO NOT EXPOSE TO RAIN OR USE IN DAMP

LOCATIONS. ON MOVING FENCE: ALWAYS ADJUST FENCE PROPERLY BEFORE USE. Clamp small

pieces before cutting. See manual. ON GUARD:DANGER – KEEP AWAY FROM BLADE. ON GUARD RETAINER PLATE: “PROPERLY SECURE BRACKET

WITH BOTH SCREWS BEFORE USE. ON DETENT PLATE: (2 PLACES) ALWAYS TIGHTEN ADJUSTMENT KNOBS BEFORE USE. KEEP

HANDS 6" FROM PATH OF SAW BLADE. NEVER PERFORM ANY OPERATION FREEHAND. NEVER CROSS ARMS IN FRONT OF BLADE. THINK! YOU CAN PREVENT ACCIDENTS. DO NOT OPERATE SAW WITHOUT GUARDS IN PLACE. NEVER REACH IN BACK OF SAW BLADE. TURN OFF TOOL, KEEP SAW HEAD DOWN AND WAIT FOR SAW BLADE TO STOP BEFORE MOVING HANDS, WORKPIECE OR CHANGING SETTINGS. UNPLUG TOOL BEFORE CHANGING BLADE, MOVING OR SERVICING UNIT.

Additional Safety Rules For Miter Saws

• CAUTION: FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL INJURY AND SERIOUS DAMAGE TO THE SAW.

• DO-Protect electric supply line with at least a 15 ampere time-delay fuse or a circuit breaker.

• DO-Make certain the blade rotates in the correct direction and that the teeth at the bottom of the blade are pointing to the rear of the miter saw.

• DO-Be sure all clamp handles are tight before starting any operation.

• DO-Be sure all blade and clamp washers are clean and recessed sides of collars are against blade. Tighten arbor screw securely.

• DO- Keep saw blade sharp.

English

Electrical Connection

Be sure your power supply agrees with the nameplate marking. 120 volts, AC/DC means that your saw will operate on alternating or direct current. A voltage decrease of 10 percent or more will cause a loss of power and overheating. All D

EWALT tools are factory tested. If this tool does not operate,

check the power supply.

Accessories

Recommended accessories for use with your tool are available at extra cost from your local service center.

CAUTION: The use of any non-recommended accessory such as dado sets, molding cutters, or abrasive wheels may be hazardous.

If you need assistance in locating any accessory, please contact D

EWALT Industrial Tool Co., 701 East Joppa

Road, Baltimore, MD 21286 or call 1-800-4-D

EWALT

(1-800-433-9258).

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" 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.

Installing a New Saw Blade (Fig. 5)

(UNPLUG THE MITER SAW) DO NOT CUT FERROUS METAL (THAT WITH AN IRON OR STEEL CONTENT) OR MASONRY WITH THIS MITER SAW.

With the saw arm in the upper position, raise the lower guard as far as possible. Loosen (but do not remove) the guard bracket screw, until the guard bracket can be raised enough to permit access to the blade screw. The blade guard will be held in the raised position by the guard bracket screw. Depress the spindle lock button. Use the supplied blade wrench in the other hand to loosen (clockwise) the left hand threaded blade screw.

NOTE: To use the spindle lock, depress the button as shown and rotate the blade by hand until you feel the lock engage. Continue to hold the lock button in to keep the spindle from turning. Remove the blade screw and the blade.

As shown in Figure 6 the inner clamp washer is installed first, then the blade adapter. The blade adapter is designed to permit the use of saw blades with 1" arbor holes as well as those with 5/8" arbor holes.

When using blades with 1" arbor holes, install the blade adapter over the spindle shaft and against the inner clamp washer, as shown in the figure. Next, install the saw blade making sure that the arbor hole in the blade fits on the blade adapter. Make sure that the teeth at the bottom of the blade are pointing toward the back of the saw (away from the operator). Install the outer clamp washer and install the blade screw. Tighten firmly using the spindle lock and the provided wrench (left hand threads). When using saw blades with 5/8" arbor holes, remove the blade adapter! Save it in a safe place for future use. The rest of the blade assembly is exactly the same.

NEVER DEPRESS THE SPINDLE LOCK PIN WHILE THE BLADE IS ROTATING.

BE SURE TO HOLD THE GUARD BRACKET DOWN AND FIRMLY TIGHTEN THE GUARD BRACKET SCREW WHEN YOU FINISH INSTALLING THE SAW BLADE. FAILURE TO DO SO WILL CAUSE SERIOUS DAMAGE TO THE SAW.

Installing Extension Kit

Side Table Extension (Some Models) BE SURE TO OBSERVE ALL OF THE SAFETY

INSTRUCTIONS IN YOUR MITER SAW INSTRUCTION MANUAL.

UNPLUG THE MITER SAW BEFORE INSTALLING, ADJUSTING OR REMOVING THE EXTENSION KIT.

The extension kit can be used on either or both sides of the saw. The supplied extension kit is factory installed on the left side:

1. Install the self-tapping stud into the hole underneath the saw.

2. Install extension tube as shown (Fig. 2) making sure the clamping bracket will catch the legs.

3. Tighten clamping bracket against the legs.

WARNING: Do not lift, support, or carry the miter saw by the extension kit. To do so may cause tipping and loss of control, leading to personal injury. NOTE: Before transporting the saw, remove the extension or telescope it into the base.

Rear Lower Guard Adjustment

Check the rear lower guard to ensure that it is located such that the saw blade is in the center and equidistant from each side, as shown in Figures 6 & 7. Adjust as necessary by loosening the two screws and moving the guard. Firmly tighten both screws. Never remove this guard.

Transporting the Saw

TURN OFF AND UNPLUG THE MITER SAW BEFORE ATTEMPTING TO MOVE IT OR MAKE ANY ADJUSTMENTS WHAT-SO-EVER!

In order to conveniently carry the miter saw from place to place, a carrying handle has been included on the top of the saw arm, as shown in Figure 3. To transport the saw, lower the arm and depress the lock down pin shown in Figure 4.

Adjustments

PERFORM ALL ADJUSTMENTS WITH THE MITER SAW UNPLUGGED 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 8. (Do not touch the tips of the blade teeth with the square. To do so will cause an inaccurate measurement.) Loosen the miter clamp knob (see Fig. 9) and swing the miter arm until the miter latch locks it at the 0 miter position. Do not tighten the clamp knob. 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. 9) 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

Loosen the miter clamp knob and squeeze the miter latch to move the miter arm to the zero position, as shown in Figure 9. With the miter clamp knob loose allow the miter latch 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 10. If the pointer does not indicate exactly zero, gently pry it left or right using a flat bladed screwdriver.

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 11B. 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 zero degrees bevel to the table. If the Bevel Arm needs adjustment, loosen the lock nut on the right side Bevel

Stop as shown in Figure 12, 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: The bevel pointer is quite thick and for accuracy’s sake set the top edge so that it aligns with zero.

BEVEL STOP

To set the 45 degree bevel stop, first loosen the left side fence clamping knobs 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 degrees, 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 degrees. 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 degree right bevel or 48 degree 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 degree positions after cuts are made.

FENCE ADJUSTMENT Turn Off and Unplug the Miter Saw

In order that the saw can bevel to a full 48 degrees left, the left side of the fence can be adjusted to the left to provide clearance. To adjust the fence, loosen the two plastic knobs 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 & down movement. Tighten both knobs securely. When the bevel operations are complete, don’t forget to relocate the fence to the right.

NOTE: The guide groove, shown in Figure 14, of the left side fence 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.

GUARD ACTUATION AND VISIBILITY

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 3-7/8” high. Page 10.

MITER LATCH

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 (120 VOLT ONLY)

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

Walt 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.

Brushes

DISCONNECT PLUG FROM POWER SUPPLY

Inspect carbon brushes regularly by unplugging tool, removing the brush inspection cap (Figure 3) and withdrawing 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 the line closest to the spring, they must be replaced. Use only identical D

EWALT 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).

While “running in” DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER SWITCH ON. HOLD BY HAND ONLY.

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 as shown in Figure 15. 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 as shown in Figure 15.

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.

Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often 45 degrees for making corners, but can be set anywhere from zero to 48 degrees left or right. After selecting the desired miter angle, be sure to tighten the miter clamp knob. Make the cut as described above.

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 degrees right to 48 degrees left and can be cut with the miter arm set between zero and 48 degrees right or left.

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 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.

For varied cutting applications, refer to the list of recommended saw blades for your saw and select the

BODY AND HAND POSITION (SEE 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" 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 16.

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 Turn Off and Unplug 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” from the blade, a clamp or other fixture should be used.

For best results us the DW7052 clamp made for use with your saw. It is available through your local retailer or D

EWALT service center at extra cost.

Other aids such as spring clamps, bar clamps or Cclamps 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.

SUPPORT FOR LONG PIECES Turn Off and Unplug Saw

ALWAYS SUPPORT LONG PIECES For best results, use the DW7050 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 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 degrees each to produce a 90 degree corner. For this joint the miter arm was locked in the zero position and the bevel adjustment was locked at 45 degrees. 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 degrees to miter the two boards to form a 90 degree corner. To make this type of joint, set the bevel adjustment to zero and the miter arm to 45 degrees. 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 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. 180 degrees 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 13 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.

DUAL RANGE MITER SCALE

The miter scale has two ranges of numbers for convenience, as shown in Figure 20. One scale indicates 0 degrees when the blade is square to the fence. At this position the other scale reads 90 degrees.

The 0 degree scale (larger numbers closer to the front edge) is used when calculating angles. To calculate the proper miter angle, divide 180 degrees by the number of sides of the box or frame. Refer to the chart on page 8 for some examples.

The 90 degree scale (smaller numbers behind the zero degree scale) is used when a corner of your box or frame is measured with a protractor. For example: if you measure the corner of an 8 sided box, the protractor will read 135 degrees. To determine the proper miter setting, divide the measured angle by two. The proper miter setting in this example is 67-1/2 degrees. Set this angle on the 90 degree scale. This is most useful when a corner is at an odd angle.

VERNIER SCALE

Your saw is equipped with a vernier scale for added precision. The vernier scale allows you to accurately set miter angles to the nearest 1/4 degree (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 degree 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 V1, with the whole degree number etched in the miter scale. Examine Figure V2 closely; the setting shown is 24 degrees right miter.

3. To set the additional 1/4 degree, squeeze the miter arm lock and carefully move the arm to the RIGHT until the 1/4 degree 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 degrees. Figure V2 shows a setting of 24-1/4 degrees right miter.

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

WHEN MITERING TO THE RIGHT

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

WHEN MITERING TO THE LEFT

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

CUTTING BASE MOLDING

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

Straight 90 degree cuts :

Position the wood against the fence and clamp it in place as shown in Figure 21. Turn on the saw, allow the blade to reach full speed and lower the arm smoothly through the cut.

above. For wider boards [up to 5.5" (5-1/2")] several minor concessions must be made.

When cutting a board between 3.9" (3-7/8") and 5.5" (5-1/2") in width the roller on the tip of the guard will 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 25. 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 3.9" (3-7/8") standing vertically against the fence as in Figure 22, 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 3-7/8" and 5-1/2" wide vertically follow the directions on next page.

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 degrees. Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52 degrees and a bottom rear angle (the part that fits flat against the wall) of 38 degrees.

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

31.62 degrees left and right for cutting crown molding at the proper angle. There is also a mark on the Bevel scale at 33.85 degrees.

The chart on this page 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 degrees, you will have to fine tune your settings anyway.

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

The angles presented for crown moldings are very

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

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

ALTERNATIVE METHOD FOR CUTTING CROWN MOLDING

Place the molding on the table at an angle between the fence and the saw table, as shown in Figure 26A. Use of the crown molding fence accessory (DW7054) 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.
