English The riving knife provided with this saw is marked as follows: .063" (1.6 mm) THICK RIVING KNIFE. ONLY FOR USE WITH 8-1/4" (210 mm) BLADE WITH .071" (1.8 mm) MIN KERF WIDTH AND .055" (1.4 mm) MAX BODY THICKNESS. Blade body thickness and kerf width dimensions for all DeWALT table saw blades are available at www.dewalt.com If a different blade is used and the body thickness and kerf width dimensions are not provided, use the following procedure to determine the correct riving knife thickness: 1. Measure the body thickness of the blade. 2. Make a shallow cut in scrap material and measure the kerf width. 3. Select the riving knife 21 . 4. Slide the riving knife through the shallow cut made in step 2 to confirm the correct riving knife has been selected. The riving knife should not bind or drag through the cut. WARNING: If any dragging or binding of the material is encountered as it reaches the riving knife, turn unit off and disconnect machine from power source. Repeat steps 1-4 to make the proper riving knife selection before attempting another cut. Kickback Kickback is a dangerous condition! It is caused by the workpiece binding against the blade. The result is that the workpiece can move rapidly in a direction opposite to the feed direction. During kickback, the workpiece could be thrown back at the operator. It can also drag the operator's hand back into the blade if the operator's hand is at the rear of the blade. If kickback occurs, turn the saw OFF and verify the proper functioning of the riving knife, anti-kickback assembly and blade guard assembly before resuming work. WARNING: See Additional Safety Rules for Table Saws and follow all warnings provided regarding KICKBACK. OPERATION WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. WARNING: Before using the saw, verify the following each and every time: • ALWAYS wear proper eye, hearing and respiratory equipment. • Blade is securely tightened. • Bevel angle and rail lock levers are locked. • If ripping, ensure that rip fence locked lever is locked and that the fence is parallel to the blade. • If crosscutting, miter gauge knob is securely tightened. • The blade guard assembly is properly attached and the anti-kickback assembly is functioning. • ALWAYS inspect the blade guard assembly and riving knife for proper alignment, operation and clearance with saw blade. • ALWAYS make sure both guards are in the down position in contact with the table before operating. WARNING: To reduce the risk of serious personal injury, have push stick ready to use before starting cut. Failure to adhere to these common safety rules can greatly increase the likelihood of injury. WARNING: Before connecting the table saw to the power source or operating the saw, always inspect the blade guard assembly and riving knife for proper operation alignment and clearance with saw blade. Personal injury may result. WARNING: Ripping or crosscutting may cause saw to tip over while operating. Make sure  saw is securely mounted to a stable surface. WARNING: Never use the fence and miter gauge together. This may cause a kickback condition and injure the operator. CAUTION: If this saw makes an unfamiliar noise or if it vibrates excessively, cease operating immediately, turn unit off and disconnect from power source until the problem has been located and corrected. Contact a DeWALT factory service center, a DeWALT authorized service center or other qualified service personnel if the problem cannot be found. WARNING: The proper throat plate must be in place at all times to reduce the risk of a thrown workpiece and possible injury. There are two basic types of cutting with table saws: ripping and crosscutting. Regardless of material, man made or natural wood, the distinction between ripping and crosscutting is as follows: Ripping is cutting to a different width (usually with the grain) and crosscutting describes cutting material across the shorter dimension (usually against the grain). WARNING: When ripping, always use the fence to provide a guide for the material and blade  guard assembly to protect against a kickback situation. WARNING: Never perform any cutting operation freehand. Never perform plunge cutting. WARNING: When crosscutting, always use the miter gauge. Do not use both the rip fence and miter gauge together. ON/OFF Switch (Fig. O) WARNING: To reduce the risk of injury, be sure the switch is in the OFF position before plugging machine in. Push green button 44 in to turn this saw on and push down the red paddle 46 to turn this saw off. Lock Off Feature Instructions A cover above the switch folds down for insertion of a padlock to lock the saw off. A padlock with a maximum diameter of 1/4" (6.35 mm) and minimum clearance of 3" (76.2 mm) is recommended. Fig. O 44 46 Guard Operating Feature (Fig. P) WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. 1. The guard arms 48 will lock in place when in the raised position. 2. This feature improves visibility when measuring the blade to fence distance. 3. Push down on guard(s) and they will release to the operating position. NOTE: Pull on the anti-kickback assembly to ensure it is locked in place. ALWAYS make sure both guards are in the down position in contact with the table before operating. Fig. P 48 Rip Fence Operation (Fig. A, Q) Rail Lock Lever (Fig. A) The rail lock lever 5 locks the fence in place preventing movement during cutting. To lock the rail lever, push it down and toward the rear of the saw. To unlock, pull it up and toward the front of the saw. WARNING: When ripping, always lock the rail lock lever. Fig. Q 50 49 Work Support Extension/Narrow Ripping Fence (Fig. A, Q) The table saw is equipped with a narrow ripping fence 18 that also supports work that extends beyond the saw table. To use the narrow ripping fence in the work support position, rotate it from its stored position as shown in Figure Q, and slide the pins into the lower sets of slots 49 on both ends of the fence. To use the narrow ripping fence in the narrow ripping position, snap the pins into the upper sets of slots 50 on both ends of the fence. This feature will allow 2" (51 mm) of extra clearance to the blade. Refer to Figure T. NOTE: When not in use, the narrow ripping fence should be placed in its stored position. 8
