User manual DEWALT DW705

[. . . ] have defective switches replaced by authorized service center. Do not use tool if switch does not turn it on and off. CAUTION: When cutting into walls, floors or wherever live electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL!Hold the tool only by insulated grasping surfaces to prevent electric shock if you cut in the live wire. [. . . ] NOTE: To adjust the depth of cut pointer for various blade diameters, loosen the Cutting Depth Adjustment Knob and raise the saw until the blade just touches the workpiece and tighten the knob. if required , loosen the screw that holds the pointer and adjust to the zero indicator mark. The saw is now adjusted to accurately indicate the depth of cut for the blade used. For the most efficient cutting action using a carbide tipped saw blade, set the Depth Adjustment so that about one half of a tooth projects below the surface of the wood to be cut. The height of a whole tooth is the distance from the tip of the tooth to the bottom of the gullet in front of it. Study Figures 5A and 5B to determine what one half tooth means. (5A shows one half tooth projecting below the surface and figure 5B shows a whole tooth projecting below the surface. ) Setting the saw at the proper cutting depth keeps blade friction to a minimum, removes sawdust from between the blade teeth, results in cooler, faster sawing and reduces the chance of kickback. a method of checking for the correct cutting depth is shown in Figure 6. Lay a piece of the material you plan to cut along the side of the blade, as shown in the figure, and observe how much tooth projects beyond the material. NOTE: When using a non carbide tipped blade, make an exception to the above procedure and allow a full tooth to project below the material, as shown in Figure 5B. Now release the blade guard and its contact with the work will keep it in position to open freely as you start the cut. Start the motor and gradually lower the saw until its shoe rests flat on the material to be cut. Advance saw along the cutting line until cut is completed. Release trigger and allow blade to stop completely before withdrawing the blade from the material. When starting each new cut, repeat as above. Never tie the blade guard in a raised position. When the saw blade becomes pinched or twisted in the cut, kickback can occur. The saw is thrust rapidly back 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 backward. When 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 exist. [. . . ] Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and toughness can vary even in the same piece of material, and knotty or damp sections can put a heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep it working without much decrease in speed. Forcing the saw can cause rough cuts, inaccuracy, kickback and over-heating of the motor. [. . . ]
