Tool Use and Care • Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. • Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. • Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
Specific Safety Rules for Circular Saws (continued) • Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to causing the blade to climb out of the kerf and jump back toward the operator. • NEVER hold piece being cut in your hands or across your leg.
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. Additional Rules For Safe Operation • Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. A wire gage size (A.W.G.

SAW BLADES KICKBACK The best of saw blades will not cut efficiently if they are not kept clean, sharp, and properly set. Using a dull blade will place a heavy load on your saw and increase the danger of kickback. Keep extra blades on hand, so that sharp blades are always available. See Figure 6. Gum and wood pitch hardened on blades will slow your saw down. Use gum and pitch remover, hot water, or kerosene to remove these accumulations. Do not use gasoline.
TO LESSEN • THE CHANCE OF KICKBACK: Always keep the correct blade depth setting - the correct blade depth setting for all cuts should not exceed 1/4 inch below the material to be cut. See • When making a cut use steady, even pressure. Never force cuts. • Do not cut warped or wet lumber. • Always hold your saw firmly with both hands and keep your body in a balanced position so as to resist the forces of kickback should it occur. Figure 8.
STARTING TO HELP MAINTAIN A CUT Know the right way to use your saw. See Figure 11. CONTROL: • Always support your workpiece near the cut. • Support your workpiece so the cut will be on your right. • Clamp your workpiece so it will not move during the cut. Place your workpiece with its good side down. Note: The good side is the side on which appearance is important. Before beginning a cut, draw a guideline along the desired line of cut.
Hold your saw firmly with both hands. See Figure 14. _k CAUTION: When lifting your saw from the workpiece, the blade is exposed on the underside of your saw until the lower blade guard closes. Make sure lower guard is closed before setting your saw down on work surface. TO CROSS CUT OR RIP CUT When making a cross cut or rip cut, align your line of cut with the outer blade guide notch on the saw base as shown in Figure 15. FRONT OF SAW RIGHT Fig. 14 Squeeze the switch trigger to start your saw.
TO BEVEL CUT When making a bevel cut hold your saw firmly with both hands as shown in Figure 17. The angle of cut of your saw may be adjusted to any desired setting between zero and 51.5 °. Note: When making cuts at 51.5 ° blade should be set at full depth of cut, with edge guide screw removed. Rest the front edge of the base on the workpiece. Squeeze the switch trigger to start your saw. Always let the blade reach full speed, then guide your saw into the workpiece.

DOUBLE INSULATION A wire gage size (A.W.G.) of at least 16 is recommended for an extension cord 100 feet or less in length. When working outdoors, use an extension cord that is suitable for outdoor use. The cord's jacket will be marked WA. Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation.
