    SAW BLADES KICKBACK See Figure 6 . 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 . 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 BLADESETTOO DEEP Fig . 6 should never be altered for any reason .

Blade stalling is caused by any action which pinches the blade in the wood . _ i DANGER : When sawing through workpiece , lower blade guard does not cover blade on the underside of workpiece .

KICKBACK IS CAUSED BY : LOWERBLADEGUARD IS IN UP POSITION • 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 .

    TO LESSEN THE CHANCE OF KICKBACK : • When making a cut use steady , even pressure . Never force cuts . • Always keep the correct blade depth setting - the • Do not cut warped or wet lumber . correct blade depth setting for all cuts should not exceed 1 / 4 inch below the material to be cut . See • Always hold your saw firmly with both hands and Figure 8 . 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 See Figure 10 . 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 . For more depth of cut accuracy , a scale is located on the upper blade guard . TO ADJUST BLADE DEPTH • Unplug your saw . CORRECTBLADEDEPTHSETTING = BLADEEXPOSED _ k WARNING : Failure to unplug your saw could 1 / 4 in . OR LESSON UNDERSIDEOF WORKPIECE result in accidental starting causing possible Fig . 8 serious personal injury . • Inspect the workpiece for knots or nails before BRACKET DEPTHOF CUTSCALE 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 . DEPTH ADJUSTMENT TO KNOB TIGHTEN f TO RAISE BAS q TO LOWER ASSEMBLY Fig . lO • Loosen depth adjustment knob . See Figure 10 . • Determine the desired depth of cut . • Locate depth of cut scale on back of upper blade guard .

    TO HELP MAINTAIN CONTROL : STARTING A CUT • Always support your workpiece near the cut . Know the right way to use your saw . See Figure 11 . • 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 solidly supported . See Figure 11 . Never place your saw on that part of the workpiece that will fall off when the cut is made . See Figure 13 . RIGHT Fig . 11 _ L 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 . Never use your saw as shown in Figure 12 . WRONG Fig . 13 Keep the cord away from cutting area .
