English center or other qualified service organization, always using identical replacement parts. Blades WARNING: To minimize the risk of eye injury, always use eye protection. Carbide is a hard but brittle material. Foreign objects in the workpiece such as wire or nails can cause tips to crack or break. Only operate saw when proper saw blade guard is in place. Mount blade securely in proper rotation before using, and always use a clean, sharp blade. WARNING: Do not cut metal, plastic, concrete, masonry or fiber cement materials with this saw. Do not use abrasive wheels or blades. A dull blade will cause slow inefficient cutting, overload on the saw motor, excessive splintering, and could increase the possibility of kickback. Please refer to the table below to determine the correct size replacement blade for your model saw. RECOMMENDED BLADE TYPES Combination Framing 5/8" Round arbor, 24 teeth All purpose fast rip and cross cuts. Pressure Treated/Wet Lumber 5/8" Round arbor, 20 teeth Coated, resistant to gum build-up Extreme Durability 5/8" Round arbor, 18 teeth Coated, rock carbide Finishing 5/8" Round arbor, 36 teeth More teeth for finer finish cuts. Fast Cut Framing 5/8" round arbor, 18 teeth Fastest blade for rips and cross cuts If you need assistance regarding blades, please call 1-800-4-DeWALT (1-800-433-9258). KICKBACK Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator. When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator. If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is more likely to occur when any of the following conditions exists. 1. IMPROPER WORKPIECE SUPPORT A. Sagging or improper lifting of the cut off piece can cause pinching of the blade and lead to kickback. B. C utting through material supported at the outer ends only can cause kickback. As the material weakens it sags, closing down the kerf and pinching the blade (Fig. 14). C. C utting off a cantilevered or overhanging piece of material from the bottom up in a vertical direction can cause kickback. The falling cut off piece can pinch the blade. D. C utting off long narrow strips (as in ripping) can cause kickback. The cut off strip can sag or twist closing the kerf and pinching the blade. E. S nagging the lower guard on a surface below the material being cut momentarily reduces operator control. The saw can lift partially out of the cut increasing the chance of blade twist. 2. IMPROPER DEPTH OF CUT SETTING ON SAW To make the most efficient cut, the blade should protrude only far enough to expose one-half of a tooth as shown in Figure 8. This allows the shoe to support the blade and minimizes twisting and pinching in the material. See the section titled Cutting Depth Adjustment. 14
