VERNIER SCALE
Your saw is equipped with a vernier scale for added precision. The vernier scale allows you to accurately set miter angles to the nearest 1/4°. To use the vernier scale follow the steps listed below.
(As an example, let’s assume that the angle you want to miter is
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° right miter.
3.To set the additional 1/4°, squeeze the miter arm lock and carefully move the arm to the RIGHT until the 1/4° vernier mark aligns with the CLOSEST degree mark on the miter scale. In our example, the closest degree mark on the miter scale happens to be 25°. Figure V2 shows a setting of
For settings that require partial degrees (1/4, 1/2, 3/4°) align the desired vernier mark with the CLOSEST degree mark on the miter scale, as described below (The plastic vernier plate is inscribed with marks for 1/4, 1/2, 3/4 and 1°. Only the 1/2° and the 1° are numerically labeled.)
WHEN MITERING TO THE RIGHT
To increase the miter angle when mitering to the right, move the arm to align the appropriate vernier mark with the closest mark on the miter scale to the right. To decrease the miter angle when mitering to the right, move the arm to align the appropriate vernier mark with the closest mark on the miter scale to the left.
WHEN MITERING TO THE LEFT
To increase the miter angle when mitering to the left, move the arm to align the appropriate vernier mark with the closest mark on the miter scale to the left. To decrease the miter angle when mitering to the left, move the arm to align the appropriate vernier mark with the closest mark on the miter scale to the right.
CUTTING BASE MOLDING
ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS. Straight 90° cuts:
Position the wood against the fence and hold it in place as shown in Figure 16. Turn on the saw, allow the blade to reach full speed and lower the arm smoothly through the cut.
CUTTING BASE MOLDING UP TO 6" (152 MM) VERTICALLY AGAINST THE FENCE
Position material as shown in Figure 16.
All cuts made with the back of the molding against the fence and bottom of the molding against the base.

CUTTING CROWN MOLDING
Your miter saw is better suited to the task of cutting crown molding than any tool made. In order to fit properly, crown molding must be compound mitered with extreme accuracy.
The two flat surfaces on a given piece of crown molding are at angles that, when added together, equal exactly 90°. Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52° and a bottom rear angle (the part that fits flat against the wall) of 38°.
Your miter saw has special
The chart below gives the proper settings for cutting crown molding. (The numbers for the miter and bevel settings are very precise and are not easy to accurately set on your saw.) Since most rooms do not have angles of precisely 90°, you will have to fine tune your settings anyway.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!
INSTRUCTIONS FOR CUTTING CROWN MOLDING LAYING FLAT AND USING THE COMPOUND FEATURES:
1.Molding laying with broad back surface down flat on saw table (Figure 17).
2.The settings below are for All Standard (U.S.) crown molding with 52° and 38° angles.

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 17A. Use of the crown molding fence accessory (DW7084) is highly recommended because of its degree of accuracy and convenience. The crown molding fence accessory is available for purchase from your local dealer.
The advantage to cutting crown molding using this method is that no bevel cut is required. Minute changes in the miter angle can be made without affecting the bevel angle. This way, when corners other than 90° are encountered, the saw can be quickly and easily adjusted for them. Use the crown molding fence accessory to maintain the angle at which the molding will be on the wall.
INSTRUCTIONS FOR CUTTING CROWN MOLDING ANGLED BETWEEN THE FENCE AND BASE OF THE SAW FOR ALL CUTS:
1.Angle the molding so the bottom of the molding (part which goes against the wall when installed) is against the fence and the top of the molding is resting on the base of the saw, as shown in Figure 17A.
2.The angled “flats” on the back of the molding must rest squarely on the fence and base of the
saw.

Special Cuts
ALUMINUM CUTTING
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM. These are available at your local DEWALT retailer or DEWALT service center. Certain workpieces, due to their size, shape or surface finish, may require the use of a clamp or fixture to prevent movement during the cut. Position the material so that you will be cutting the thinnest cross section, as shown in Figure 18. Figure 18A illustrates the wrong way to cut these extrusions. Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax directly to the saw blade before cutting. Never apply stick wax to a moving blade.
The wax, available at most hardware stores and industrial mill supply houses, provides proper lubrication and keeps chips from adhering to the blade.
Be sure to properly secure workpiece.
Refer to Saw Blades under Optional Accessories for correct saw blade.
BOWED MATERIAL
When cutting bowed material always position it as shown in Figure 19 and never like that shown in Figure 19A. Positioning the material incorrectly will cause it to pinch the blade near the completion of the cut.
CUTTING PLASTIC PIPE OR OTHER ROUND MATERIAL
Plastic pipe can be easily cut with your saw. It should be cut just like wood and CLAMPED OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important when making angle cuts.
CUTTING LARGE MATERIAL
Occasionally you will encounter a piece of wood a little too large to fit beneath the blade guard. If this occurs, simply place your right thumb on the upper side of the guard and roll the guard up just enough to clear the workpiece, as shown in Figure 20. 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 10" (406 mm)] workpieces when a special set up is used. To set the saw up for these workpieces, follow these steps:
1.Remove both left and right sliding fences from the saw and set aside. To remove them, unscrew the fence knobs several turns and slide each fence outward. Adjust and lock the miter control so that it is at 0° miter.
2.Make a platform using a piece of 1.5 inch (38 mm) thick particleboard or similar flat strong 1.5" (38 mm) thick wood to the dimensions: 10" x 24" (254 x 610 mm). The platform must be flat otherwise the material could move during cutting and cause injury.
3.Mount the 10" x 24" (254 x 610 mm) platform to the saw using 4
WARNING: Ensure the saw is mounted firmly to a stable flat surface. Failure to do so could cause the saw to be unstable and fall causing personal injury.
4.Place the workpiece to be cut on top of the platform mounted to the table. Ensure the workpiece is firmly against the backfence (Fig. 9).
5.Secure the material before cutting. Cut slowly through the material. Failure to clamp securely or cut slowly could result in the material coming loose and causing injury.
After several cuts are made at various miter angles other than 0º, the platform may weaken and not properly support the work. Install a new, unused platform to the saw after presetting the desired miter angle.
CAUTION: Continued use of a platform with several kerfs may cause loss of material control and possible injury.
Removing and Replacing Belt
The belt is designed to last the life of the tool. However, abuse of the tool could cause the belt to fail.
If the blade does not turn when the motor is running, the belt has failed. To inspect or replace the belt, remove the belt cover screws. Remove the belt cover. Inspect the ribs of the belt for wear or failure. Check belt tension by squeezing the belt as shown in Figure 21. 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 or return the tool to the nearest service center for repair. Service center locations are packed with your tool.
