ELECTRICAL SAFETY cont. 8. When operating a power tool outside, ALWAYS use an outdoor extension cord marked "#V-A" or "W". These cords are rated for outdoor use and reduce the risk of electric shock. NOTE: The extension cord must have adequate wire size AWG (American Wire Gauge) for safe, efficient use. Smaller gauge wires, have greater capacity (16 gauge wire has more capacity than 18 gauge wire). Minimum Gauge for Extension Cords (AWG) Volts Total Length of Cord in Feet 120V 025ft. 26 50ft.
TOOL USE AND CARE SAFETY 1. ALWAYS use clamps or other practical ways 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. 2. DO NOT force tool. Use the correct tool and blade for your application. The correct tool and blade will do the job better and safer at the rate for which it is designed. 3. DO NOT use tool if switch does not turn it "On" or "Off".
SAFETY RULES FOR CIRCULAR SAWS Z_ DANGER! Keep hands away from cutting area and blade. Keep your second hand on the auxiliary handle or motor housing. If both hands are holding the saw, they cannot be cut by the blade. 1. ALWAYS keep your body positioned to either side of the saw blade, but not in line with the saw blade. Kickback could cause the saw to jump backwards. (See Kickback...What Causes It and Ways to Prevent It on pages 7-8). 2. DO NOT reach underneath the work.
SAFETY RULES FOR CIRCULAR SAWS cont. 11. ALWAYS BE SURE that all adjusting screws and the blade holder are fastened tightly BEFORE making a cut. Loose adjusting screws and holders can cause the tool or blade to slip and loss of control may result. 12. When removing the blade from the tool, ALWAYS avoid contact with skin and ALWAYS wear protective gloves when grasping the blade or accessory. Accessories may be hot after prolonged use. KICKBACK...
Ways to Prevent Kickback cont. 5. DO NOT use a dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf which causes excessive friction, blade binding and KICKBACK. 6. ALWAYS be sure that the blade depth and adjusting locking levers are tight and secure BEFORE making a cut. If blade adjustment shifts while cutting, it may cause binding and KICKBACK. 7. ALWAYS use extra caution when making a "Pocket Cut" into existing walls or other blind areas.
ADDITIONAL RULES FOR SAFE OPERATION cont. 6. ALWAYS check for damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine if it will operate properly and perform its intended function. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. A guard or other part that is damaged, should be properly repaired or replaced at a Sears Service Center.
ADDITIONAL RULES FOR SAFE OPERATION cont. WARNING: Some dust particles created by power sanding, sawing, grinding, drilling and other construction jobs contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead-based paints. • Crystalline silica from bricks and cement and other masonry products. • Arsenic and chromium from chemically-treated lumber.
Before attempting to use any tool, be sure to familiarize yourself with all the operating features and safety instructions. KNOWYOUR SAW (See Fig. 1) Your circular saw has many built-in convenience features for fast, efficient cutting. These features include easy to operate adjustments for depth-of-cut and bevel cutting. Electrical Connection Your circular saw has a precision-built electric motor and it should only be connected to a 120-volt, 60-Hz. power supply (normal household current).
UNPACKING Your circular saw has been shipped completely assembled, except for the blade, which is packed unassembled.

SAW BLADES All saw blades need to be kept clean, sharp and properly set in order to cut efficiently. Using a dull blade places a heavy load on the saw and increases the danger of kickback. Keep extra blades on hand, so sharp blades are always available. Gum and wood pitch hardened on the blade slows the saw down.
KICKBACK 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.

SERVICE WARNING: Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components, which could cause a serious hazard, 1. Tool service MUST BE performed only by a Sears Service Center. Service or maintenance performed by unqualified personnel could result in a risk of injury. IMPORTANT NOTE: All service that requires opening the saw should only be performed at a Sears Service Center. 2. When servicing a tool, ALWAYS use only identical replacement parts.
DOUBLE INSULATION Double insulation is a concept in safety in electric power tools, which eliminates the need for the standard 3-wire grounded power cord. All exposed metal parts are isolated from the internal motor components with protecting insulation. Double insulated tools do not need to be grounded. IMPORTANT The servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician.
