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 GERNERAL POWER TOOL SAFETY WARNINGS WARNING: Read all safety warnings and all 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 1. Keep work area clean and well lit. Cluttered and dark areas invite accidents. 2.
SAFETY INSTRUCTIONS POWER TOOL USE AND CARE 1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and more safely at the rate for which it was designed. 2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. 3.
SAFETY INSTRUCTIONS 5. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding. 6. Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control. 7. Never use damaged or incorrect blade washers or bolt.
SAFETY INSTRUCTIONS 4. Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.
