SAFETY SYMBOLS Some of these following symbols may be used on this tool. Please study them and learn their meaning. Proper interpretation of these symbols will allow you to operate the tool better and more safely.
SAFETY INSTRUCTIONS The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols and the explanations with them deserve your careful attention and understanding. The symbol warnings do not, by themselves, eliminate any danger. The instructions and warnings they give are no substitutes for proper accident prevention measures.
SAFETY INSTRUCTIONS WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and / or serious injury. Save all warnings and instructions for future reference. The term power tool in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. WARNING: Risk of fire and electric shock. Dry location use only. Do not expose to rain. Risk of injury. WORK AREA SAFETY 1.
SAFETY INSTRUCTIONS 6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. 7. If devices are provided for the connection of dust extraction and collection facilities, ensure that these are connected and properly used. Use of these devices can reduce dust-related hazards. USE AND CARE OF THE POWER TOOLS 1. Do not force the power tool.
SAFETY INSTRUCTIONS SPECIFIC SAFETY RULES FOR CIRCULAR SAWS CAUSES AND OPERATOR PREVENTION OF KICKBACK DANGER: Keep hands away from cutting area and blade. Keep your second hand on auxillary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
SAFETY INSTRUCTIONS 4. Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel. 5. Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerfs causing excessive friction, blade binding and kickback. 6. Blade depth and bevel adjusting locking levers must be tight and secure before making cut.

ASSEMBLY WARNING: If any part is broken or missing, do not attempt to plug in the power cord or operate the tool until the broken or missing part is replaced. Failure to do so could result in possible serious injury.
OPERATION TO ATTACH BATTERY PACK (FIG. 1) FIG. 1 BLADE GUARD SYSTEM (FIG. 2) FIG. 2 Lower blade guard is in up position when making a cut Blade exposed on underside of workpiece NOTICE: Use with the battery packs listed on page 7 only. 1. Make sure that the circular saw is “OFF”. 2. Align the raised rib on the battery pack with the grooves on the bottom of the saw, and then slide the battery forward to attach the battery pack to the saw.
OPERATION SAW BLADES WARNING: When using the saw, always stay alert and exercise control. Do not remove the saw from the workpiece while the blade is moving. WARNING: A 6-1/2-inch blade is the maximum blade capacity of your saw. A blade larger than 6-1/2 inches will come in contact with the blade guards. NEVER use a blade that is so thick that it prevents the outer blade washer from engaging with the flat side of the spindle.
OPERATION To avoid kickback, always follow these instructions: FIG. 6 CORRECT SUPPORT Kickback occurs when the blade stalls rapidly and the saw is driven back towards the operator. Blade stalling is caused by any action that pinches the blade in the wood. To guard against kickback, avoid dangerous practices such as the following: • Setting blade depth incorrectly. • Sawing into knots or nails in the workpiece. • Twisting the blade while making a cut.
OPERATION LOCK-OFF BUTTON (FIG. 7) DEPTH OF CUT ADJUSTMENTS (FIG. 8) FIG. 7 FIG. 8 Lock-off button Trigger switch The lock-off button reduces the possibility of accidental starting. The lock-off button is located on the handle above the trigger switch. The lock-off button must be depressed before you squeeze the trigger switch. NOTICE: The lock-off button can be operated from either the left or right side. Always keep the correct blade depth setting.
OPERATION OPERATING THE SAW (FIG. 9-FIG. 10) It is important to understand the correct method for operating the saw. Refer to the figures in this section to learn the correct and incorrect ways for handling the saw. DANGER: When lifting the saw from the workpiece, the blade is exposed on the underside of the saw until the lower blade guard closes. Make sure the lower blade guard is closed before setting the saw down. WARNING: To make sawing easier and safer, always maintain proper control of the saw.
OPERATION WARNING: ALWAYS clamp and support workpiece securely. ALWAYS maintain proper control of saw. Failure to clamp and support workpiece and loss of control of saw could result in serious injury. INTEGRATED RIP AND CROSSCUT RULERS Marked along the base across the front of the saw is a ruler for measuring repetitive cuts. The markings on the front of the base are in increments of 1/2-inch (12.7 mm). NOTICE: The distance from the line of cut to the guideline is the amount you should offset the guide.
OPERATION MAKING RIP CUTS The combination blade provided with your saw is for both cross cuts and rip cuts. Ripping is cutting lengthwise with the grain of the wood (FIG. 12). FIG. 12 Desired width of cut WARNING: ALWAYS clamp and support workpiece securely. ALWAYS maintain proper control of saw. Failure to clamp and support workpiece and loss of control of saw could result in serious injury. BEVEL CUTTING The angle of cut can be adjusted to any desired setting between 0°and 50°.
OPERATION MAKING A BEVEL CUT (FIG. 15) Line of cut FIG. 15 45°indicator 1. Secure workpiece with clamps. When making a bevel cut, hold the saw firmly with both hands. 2. Rest the front edge of the base on the workpiece. Depress the lock-off button and squeeze the trigger switch to start the saw. Allow the saw to reach full speed before before allowing the saw blade to contact the workpiece. 3. After completing the cut, release the trigger switch and allow the blade to come to a complete stop.
OPERATION WARNING: Always remove the battery pack from the tool when assembling parts, changing blades and making adjustments. Failure to obey this warning could cause serious personal injury. 2. Using a carpenter’s square, check the squareness of the saw blade to the base of the saw. TO ADJUST 0° BEVEL STOP (FIG. 17) FIG. 17 1. 2. 3. 4. 0° bevel stop adjusting screw Remove the battery pack from the saw. Loosen the bevel adjustment knob. Turn over the saw on a workbench.
OPERATION 10. Release the trigger switch and allow the blade to come to a complete stop. 11. Lift the saw from the workpiece. 12. Clear corners out with a hand saw or saber saw. WARNING: Never tie the lower blade guard in the raised position. Leaving the blade exposed could result in serious injury MAINTENANCE WARNING: To ensure safety and reliability, all repairs should be performed by a qualified service technician at an Authorized Service Center.
MAINTENANCE WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc. come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic, which may result in serious personal injury. Periodic maintenance allows for long life and troublefree operation. A cleaning and maintenance schedule should be maintained. As a common preventive maintenance practice, follow these recommended steps: 1.
MAINTENANCE 1. R emove the battery pack from the saw. 2. Loosen the depth of cut adjustment lever. Raise the saw to the maximum height and tighten the depth of cut adjustment lever. 3. Locate and remove the hex key from the storage area. 4. Depress the spindle lock button, place the hex key in the blade screw and move the hex key back and forth until you feel the spindle lock button depress further. This action locks the blade in position so the blade screw can be removed.
TROUBLESHOOTING PROBLEM The blade does not follow a straight line: The blade binds or smokes from friction: Page 23 CAUSE SOLUTION Teeth are dull. This is caused by hitting a hard object such as a nail, dulling teeth on one side. The blade tends to cut to the side with the sharpest teeth. Change to a new blade. Base is out of line or bent. Have the tool repaired by a qualified service technician. Blade is bent. Change to a new blade. Blade is dull. Sharpen or change to a new blade.
