WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss. WARNING: NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE FENCE. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California 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. 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. WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body. 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 MITER SAW. WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS. DO NOT EXPOSE TO RAIN OR USE IN DAMP LOCATIONS. ALWAYS USE PROPER EYE AND RESPIRATORY PROTECTION. ON MOVING FENCES: ALWAYS ADJUST FENCE PROPERLY BEFORE USE. CLAMP SMALL PIECES BEFORE CUTTING. SEE MANUAL. ON GUARD: DANGER-KEEP AWAY FROM BLADE. ON UPPER GUARD: PROPERLY SECURE BRACKET WITH BOTH SCREWS BEFORE USE. ON TABLE: (2 PLACES) WARNING: FOR YOUR OWN SAFETY, READ INSTRUCTION MANUAL BEFORE OPERATING MITER SAW. KEEP HANDS OUT OF PATH OF SAW BLADE. DO NOT OPERATE SAW WITHOUT GUARDS IN PLACE. CHECK LOWER GUARD FOR PROPER CLOSING BEFORE EACH USE. ALWAYS TIGHTEN ADJUSTMENT KNOBS BEFORE USE. DO NOT PERFORM ANY OPERATION FREEHAND. NEVER REACH IN BACK OF SAW BLADE. NEVER CROSS ARMS IN FRONT OF BLADE. TURN OFF TOOL AND WAIT FOR SAW BLADE TO STOP BEFORE MOVING WORKPIECE, CHANGING SETTINGS OR MOVING HANDS. DISCONNECT POWER BEFORE CHANGING BLADE OR SERVICING. TO REDUCE THE RISK OF INJURY, RETURN CARRIAGE TO THE FULL REAR POSITION AFTER EACH CROSSCUT OPERATION. THINK! YOU CAN PREVENT ACCIDENTS. ON BASE: (2 PLACES) FIG. 1 DW7080 END PLATE DW7082 LOCKNUTS KNOBS Electrical Connection Be sure your power supply agrees with the nameplate marking. 120 volts, AC means that your saw will operate on alternating current. The switch is susceptible to failure if direct current is used. A voltage decrease of 10 percent or more will cause a loss of power and overheating. All DEWALT tools are factory tested. If this tool does not operate, check the power supply. Accessories WARNING: Since accessories, other than those offered by DEWALT, have not been tested with this product, use of such accessories with this tool could be hazardous. To reduce the risk of injury, only DEWALT recommended accessories should be used with this product.

Optional Accessories (Fig. 1) The following accessories, designed for your saw, may be helpful. In some cases, other locally obtained work supports, length stops, clamps, etc., may be more appropriate. Use care in selecting and using accessories. Extension Work Support: DW7080 Used to support long overhanging workpieces, the work support is user assembled. Your saw base is designed to accept two work supports, one on each side. Adjustable Length Stop: DW7051 Requires the use of one Extension Work Support (DW7080) (refer to Figure 1). It is used to make repetitive cuts of the same length from 0 to 42" (107 cm). Clamp: DW7082 (similar model included) Used for firmly clamping workpiece to the saw table for precision cutting. Dust Bag: DW7053 (included with some models) Equipped with a zipper for easy emptying, the dust bag will capture the majority of the sawdust produced. Crown Molding Fence: DW7084 Used for precision cutting of crown molding. SAW BLADES: ALWAYS USE 12" (305 mm) SAW BLADES WITH EITHER 1" (25.4 mm) OR 5/8" (15.88 mm) ARBOR HOLES. SPEED RATING MUST BE AT LEAST 4800 RPM. Never use a smaller diameter blade. It will not be guarded properly. Use crosscut blades only! Do not use blades designed for ripping, combination blades or blades with hook angles in excess of 7°.
