English FIG. 29 KERF WIDTH (WIDTH OF CUT MADE BY THE BLADE) RIVING KNIFE THICKNESS FIG. 30 BODY (OR PLATE) THICKNESS OF THE BLADE All DEWALT blade body thickness and kerf widths are provided 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. FIG. 31 2. Make a shallow cut in scrap material and measure the kerf width. 3. Select the riving knife as shown in Figure 29. 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. IMPORTANT: 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: Refer to Additional Safety Rules for Table Saws and follow all warnings provided regarding KICKBACK. OPERATION WARNING: Before using the saw, verify the following each and every time: 1. ALWAYS wear proper eye, hearing and respiratory equipment. 2. Blade is tight. 3. Bevel angle and height lock knobs are tight. 4. If ripping, ensure fence lock lever is tight and fence is parallel to the blade. 5. If crosscutting, miter gauge knob is tight. 6. The blade guard assembly is properly attached and the anti-kickback assembly is functioning. 7. ALWAYS inspect the blade guard assembly and riving knife for proper alignment, operation and clearance with saw blade. 8. ALWAYS make sure both guards are in the down position in contact with the table before operating. Failure to adhere to these common safety rules can greatly increase the likelihood of injury. WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing setups or when making repairs. An accidental start-up can cause 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 your 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. CAUTION: 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. Cutting with the grain is ripping and cutting against the grain is crosscutting. With manmade materials, the distinction is made such that ripping is cutting to a different width and crosscutting describes cutting material across the shorter dimension. WARNING: When ripping, always use the fence to provide a guide for the material and blade guard assembly against a kickback situation. WARNING: Never perform any cutting operation freehand. Never perform plunge cutting. CAUTION: When crosscutting, always use the miter gauge. Guard Operating Feature (Fig. 32) WARNING: To reduce the risk of injury, turn unit off and disconnect machine from power source before installing and removing accessories, before adjusting or changing setups or when making repairs. An accidental start-up can cause injury. 1. The guard(s) will lock in place when in the raised position. 2. This feature increases visability when measuring the blade to fence distance. 3. Push down on guard(s) and they will release to the operating position. • ALWAYS make sure both guards are in the down position in contact with the table before operating.
