[. . . ] 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. CAUTION: If saw is dropped, lower guard may be bent, restricting full return. Large panels must be supported as shown in Figure 14 to minimize the risk of blade pinching and kickback. [. . . ] 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. (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. On the front of the saw is a bevel angle adjustment mechanism consisting of a calibrated quadrant (J) and a knob, (K). To set the saw for a bevel cut, loosen (counterclockwise) the quadrant 8) The front of the saw shoe has a kerf indicator (L) for vertical and bevel cutting. This indicator enables you to guide the saw along cutting lines penciled on the material being cut. The indicator lines up with the left (inner) side of the saw blade, which makes the slot or "kerf" cut by the moving blade fall to the right of the indicator. Snagging the lower guard on a surface below the material being cut momentarily reducing operator control. The saw can lift partially out of the cut increasing the chance of blade twist. IMPROPER DEPTH OF CUT SETTING ON SAW Using the saw with an excessive depth of cut setting increases loading on the unit and susceptibility to twisting of the blade in the kerf. It also increases the surface area of the blade avaliable for pinching under conditions of kerf close down. When retracting the lower blade guard to install the blade, check the condition and operation of the lower blade guard to assure that it is working properly. Make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. Place outer clamp washer (F) on saw spindle with the large flat surface against the blade and the wording on the outer clamp washer facing you. Thread blade clamping screw (G) into saw spindle by hand (screw has right-hand threads and must be turned clockwise to tighten). Depress the blade lock (B) while turning the saw spindle with the blade wrench until the blade lock engages and the blade stops rotating (Fig. NOTE: Never engage the blade lock while saw is running, or engage in an effort to stop the tool. To loosen the blade clamping screw (G), depress the blade lock (B) and turn the saw spindle with the blade wrench until the blade lock engages and the blade stops rotating. [. . . ] As examples, Figure15 illustrates the RIGHT way to cut off the end of a board, and Figure 16 the WRONG way. CUTTING Be sure saw is up to full speed before blade contacts material to be cut. Starting saw with blade against material to be cut or pushed forward into kerf can result in kickback. Push the saw forward at a speed which allows the blade to cut without laboring. [. . . ]
