OPERATION DANGER: Release switch immediately if blade binds or saw stalls. Kickback could cause you to lose control of the saw. Loss of control can lead to serious injury. To guard against kickback, avoid dangerous practices such as the following:  Setting blade depth incorrectly  Sawing into knots or nails in workpiece  Twisting the blade while making a cut  Making a cut with a dull, gummed up, or improperly set blade  Supporting the workpiece incorrectly  Forcing a cut  Cutting warped or wet lumber  Operating the tool incorrectly or misusing the tool To lessen the chance of kickback, follow these safety ­practices:  Keep the blade at the correct depth setting. Less than a full tooth of the blade teeth should be visible below the workpiece.  Inspect the workpiece for knots or nails before cutting. Never saw into a knot or nail.  Make straight cuts. Always use a straight edge guide when rip cutting. This helps prevent twisting the blade.  Use clean, sharp, and properly set blades. Never make cuts with dull blades.  Support and clamp the workpiece properly before beginning a cut.  Use steady, even pressure when making a cut. Never force a cut.  Do not cut warped or wet lumber.  Hold the saw firmly with both hands and keep your body in a balanced position so as to resist the forces if kickback should occur. WARNING: When using the saw, always stay alert and exercise control. Do not remove the saw from the workpiece while the blade is moving. SAW BLADES 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 the saw and increase the danger of kickback. Keep extra blades on hand, so that sharp blades are always available. Gum and wood pitch hardened on blades will slow the saw down. Remove saw blade from the saw and use gum and pitch remover, hot water, or kerosene to remove these accumulations. DO NOT USE GASOLINE. BLADE GUARD SYSTEM See Figure 8, page 16. The lower blade guard attached to the circular saw is there for your protection and safety. Do not alter it for any reason. If it becomes damaged, do not operate the saw until you have the guard repaired or replaced. Always leave guard in operating position when using the saw. DANGER: When sawing through work, lower blade guard does not cover blade on the underside of work. Since blade is exposed on underside of work, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury. WARNING: Never tie the lower blade guard in a raised position. Leaving the blade exposed could lead to serious injury. CAUTION: Never use saw when guard is not operating correctly. Check the guard for correct operation before each use. The guard is operating correctly when it moves freely and readily returns to the closed position. If you drop the saw, check the lower blade guard and bumper for damage at all depth settings before reuse. If at any time the lower blade guard does not snap closed, unplug the saw from the power supply. Exercise the lower guard by moving it rapidly back and forth from the full open position to the closed position several times. Normally this will restore the guard to its normal operating condition. If it does not correct a slow or sluggish closing lower guard, do not use the saw. Take it to an authorized factory service center for repair. 9 - English
