4. Safety Instructions

WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

4.1 Work Area Safety

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

4.2 Electrical Safety

• Power tool plugs must match the outlet. Never modify the plug in any way.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool.

4.3 Personal Safety

• Always wear eye protection. Use safety glasses, goggles, or a face shield.
• Wear appropriate personal protective equipment (PPE) such as dust masks, non-skid safety shoes, hard hats, or hearing protection.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.

4.4 Circular Saw Specific Safety

• DANGER: Keep hands away from cutting area and the 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.
• Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
• Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade should be visible below the workpiece.
• Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform.
• Always use blades of the correct size and type for the material being cut.
