GENERAL POWER TOOL SAFETY WARNINGS AND 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. Work Area SAFETY Keep work area clean and well lit. Cluttered or dark areas invite accidents.
GENERAL POWER TOOL SAFETY WARNINGS AND INSTRUCTIONS Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation. SERVICE Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
circular saw safety warnings and instructions Check lower guard for proper closing before each use. Do not operate saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. Check the operation of the lower guard spring.

ELECTRICAL DOUBLE INSULATION EXTENSION CORDS Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.

FEATURES KNOW YOUR CIRCULAR SAW ERGONOMIC DESIGN See Figure 1. The safe use of this product requires an understanding of the information on the product and in this operator’s manual as well as a knowledge of the project you are attempting. Before use of this product, familiarize yourself with all operating features and safety rules. The design of your circular saw provides for maintaining proper two hand control when cutting. It has been designed to be comfortable and easy to grasp.
ASSEMBLY WARNING: SPINDLE A 7-1/4 in. blade is the maximum blade capacity of the saw. Also, never use a blade that is too thick to allow outer blade washer to engage with the flat on the spindle. Larger blades will come in contact with the blade guards, while thicker blades will prevent blade screw from securing blade on spindle. Either of these situations could result in a serious accident.
ASSEMBLY REMOVING BLADE Remove spring washer and outer blade washer (“D” washer). See Figures 2 - 4. Unplug the saw. Lift lower blade guard. Remove blade. Depress and hold spindle lock button. Remove blade screw by turning it counterclockwise with the blade wrench, while keeping the spindle lock button depressed. OPERATION WARNING: 56 Do not allow familiarity with this product to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury.
OPERATION Making a cut with a dull, gummed up, or improperly set blade CORRECT SUPPORT 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. Fig. 8 Inspect the workpiece for knots or nails before cutting.
OPERATION 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. SWITCH STARTING/STOPPING THE SAW See Figure 10.
OPERATION OPERATING THE SAW See Figures 12 - 14. 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. WARNING: To make sawing easier and safer, always maintain proper control of the saw. Loss of control could cause an accident resulting in possible serious injury.
OPERATION CROSS CUTTING/RIP CUTTING BLADE GUIDE NOTCH See Figures 15 - 16. When making a cross cut or rip cut, align the line of cut with the outer blade guide notch on the base as shown in the figure. Since blade thicknesses vary, always make a trial cut in scrap material along a guideline to determine how much, if any, you must offset the guideline to produce an accurate cut. NOTE: The distance from the line of cut to the guideline is the amount you should offset the guide.
OPERATION TO BEVEL CUT See Figure 18 - 19. Hold the saw firmly with both hands as shown. Rest the front edge of the base on the workpiece. Start the saw and let the blade reach full speed. Guide the saw into the workpiece and make the cut. Release the switch trigger and allow the blade to come to a complete stop. TIGHTEN Lift the saw from the workpiece. POCKET CUTTING See Figure 20. WARNING: Always adjust bevel setting to zero before making a pocket cut.
OPERATION 0° BEVEL STOP See Figure 21. The saw has a 0° bevel stop that has been factory adjusted to assure 0° angle of the saw blade when making 90° cuts. To check 0° bevel stop: Unplug the saw. Place the saw in an upside down position on a workbench. Check the squareness of the saw blade plate to the base of the saw using a combination square. bevel adjustment knob To adjust 0° bevel stop: Unplug the circular saw. Loosen bevel adjustment knob.
OPERATION OPTIONAL Edge guide See Figure 23. Use the optional edge guide, part no. 969862009, when making long or wide rip cuts with the saw. To assemble edge guide: Unplug the saw. Place edge guide through holes in base as shown in the figure. Adjust edge guide to the width needed. edge guide lock knob Tighten edge guide lock knob securely. To use edge guide: Secure the workpiece. Position the face of the edge guide firmly against the edge of workpiece.
MAINTENANCE Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this product for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the product using compressed air.
