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. 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. BLADE GUARD SYSTEM The lower blade guard attached to your circular saw is there for your protection and safety. It should never be altered for any reason. If it becomes damaged or begins to return slow or sluggish, do not operate your saw until the damage has been repaired or replaced, Always leave guard in operating position when using saw. DANGER: When sawing through workpiece, lower blade guard_does not cover blade on the underside of workpiece. Since blade is exposed on underside of workpiece, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury. See Figure 5. LOWERBLADEGUARD IS INUPPOSITION WHENMAKINGA CUT KICKBACK See Figure 6. KICKBACK=_ /7, -..--= BLADESETTOODEEP Fig. 6 The best guard against kickback is to avoid dangerous practices. Kickback occurs when the blade stalls rapidly and the saw is driven back towards you, Blade stalling is caused by any action which pinches the blade in the wood, ,_ DANGER: Release switch immediately if blade binds or saw stalls. Kickback could cause you to lose control of your saw. Loss of control can lead to serious injury. KICKBACK IS CAUSED BY: • Incorrect blade depth setting. See Figure 6. • Sawing into knots or nails in workpiece. • Twisting blade while making a cut. • Making a cut with a dull, gummed up, or improperly set blade. • Incorrectly supporting workpiece. See Figure 7. A BLADEEXPOSEDON UNDERSIDEOF WORKRECE Fig, 5 CAUTION: Never use saw when guard is not operating correctly. Guard should be checked for correct operation before each use. If you drop your saw, check the lower blade guard and bumper for damage at all depth settings before reuse. NOTE: The guard is operating correctly when it moves freely and readily returns to the closed position. If for any reason your lower blade guard does not close freely, take it to the nearest Sears Parts and Repair Center for service before using. WRONG Fig, 7 • Forcing a cut. • Cutting warped or wet lumber. • Tool misuse or incorrect operating procedures. Page 9 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 Figure 8. CORRECTBLADEDE!_'H SETTING= BLADEEXPOSED1/4 in. OR LESS ON UNDERSIDEOF WORKPIECE Fig. 8 • Inspect the workpiece for knots or nails before beginning a cut. 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 in the cut. • Always use clean, sharp and properly set blades. Never make cuts with dull blades. • To avoid pinching the blade, support the workpiece properly before beginning a cut. The right and wrong ways to support large pieces of work are shown in figures 7 and 9. RIGHT Fig. 9 • 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• When using your saw, always stay alert and exercise control. Do not remove your saw from workpiece while the blade is moving, DEPTH OF CUT ADJUSTMENT Always keep correct blade depth setting, The correct blade depth setting for all cuts should not exceed 1/4 inch below the material to be cut. More blade depth will increase the chance of kickback and cause the cut to be rough, TO ADJUST BLADE DEPTH • Unplug your saw. _, WARNING: Failure to unplug your saw could result in accidental starting causing possible serious personal injury. • Loosen wing nut. See Figure 10. WING BASE NUT ASSEMBLY Fig. 10 • Hold base flat against the workpiece and raise or lower saw until the required depth is reached. • Tighten wing nut securely. Page 10 STARTING A CUT Know the right way to use your saw. See Figure 11. O RIGHT 1,- Fig. 11 Never use your saw as shown In figure 12. WRONG Fig. 12 Never place your hand on the workpiece behind your saw while making a cut. _IL WARNING: To make sawing easier and safer, always maintain proper control of your saw. Loss of control of your saw could cause an accident resulting in possible serious injury. TO HELP MAINTAIN 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. Then place front edge of base on that part of your workpiece that is solidi...
