Set and test the anti-kickback device the same as in RIPPING even though only one of the fingers will take the main “bite”, if needed.-Remember to raise the front, lower blade guard to clear rip fence if needed. Figure §13 20 DADO & PLOUGH CUTS (CUTTING GROOVES) Figure S14 A “Dado” is a grmm mmm the wood grain Ccrosscut) (figure S14). A “Plough" is a groove with the wood grain (rip) (Figure $15). These cuts can be made to any width with a regular saw blade by miking one cut next to another until the desired width is .achieved.: The .depth-, of the groove is controlled by the amount of elevation given to the saw blade. A 6* diameter Dado Set (or Oado Head) will make dados or ploughs in widths from 1/8" to 13/16" in one cut. The Dado set consists of 2 saw.....blades........1/8" thick, 4 chipper*......1/8" thick, and one chipper 1/16* thick. The 2 blades, when placed together cut a groove 1/4" wide. As chippers are placed between the blades the cutting width will be increased accordingly. The chippers are “swedged” (their cutting ends are flared out), and when placing them between the blades, the swedges must fall in the tooth gullets of any blade next to them (see Figure $16). When using 2 or more chippers their ends can be spaced evenly around the circumference or not—it doesn't matter. As you make the dado wider you will have to remove the spacer washers on the saw arbor (see Figure S17). The easiest method for setting the proper depth of cut, is to measure the thickness of the lumber and subtract from this the depth of the desired dado. The result will be the dimen* sion that the bottom of the dado head should be set above the table top. Follow the same procedure in making cuts with the dado head as you would with a regular saw blade, although slower cutting is recommended, When ploughing, be sure to lower the guard extension to 1/8* above the-wood and lower the anti-kickback assembly so that the fingers hang to 1 /8" lower than the top surface of the material being cut. Test the grabbing action of the fingers as previously explained under RIPPING* Also, when feeding -material into a plough cut, push the wood down as well as forward, as the dado head will have a tendency to lift the wood as it cuts. CAUTION ALWAYS WEAR PROTECTIVE GOGGLES, WEAR OUST MASK IF OPERATION IS DUSTY. Figure $16 Figure SJ7 If saw blade jams, check the tightness of the roller head.

Using the proper blade is most important and no matter what type of blade you use it’s wrong if it is not sharp. A dull blade can do harm to the material you are cutting, to your DeWalt saw, and last but not least to you. A sharp blade is the most efficient. The proper blade will produce the best results. We suggest three (3) basic blades. First the one which comes with the saw—a COMBINATION BLADE for all around cutting of hard or soft woods. It will lose its edge quickly if used on plywood, chipboard, masonite, plastics, dirty lumber, and painted or varnished boards. This blade makes an ordinary saw cut that usually must be sanded or planed if a smooth finish is desired. Second, to cut plywood, chipboards, masonite, etc, use a PLYWOOD BLADE (small teeth). It will hold an edge longer, does not splinter plywood, and cuts quite smoothly. Third, to cut a finished or planed edge, a HOLLOW GROUND PLANER blade is best (Not for plywood, masonite etc.) It requires more power to drive a hollow ground blade since this blade has a tendency to burn the wood. It must be kept very sharp and clean. To assist you in selecting blades a saw blade selection chart is shown below. _ .
