RULES FOR SAFE OPERATION Safe operation of this power tool requires that you read and understand this operator's manual and all labels affixed to the tool. Safety is a combination of common sense, staying alert, and knowing how your bench grinder works. READ ALL INSTRUCTIONS n KNOW YOUR POWER TOOL. Read the operator's manual carefully. Learn the applications and limitations as well as specific potential hazards related to this tool.
RULES FOR SAFE OPERATION n USE OUTDOOR EXTENSION CORDS. Use only extension cords with approved ground connection that are intended for use outdoors and so marked. n NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the grinding path of the wheel. n AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause your hand to move into the wheel. ALWAYS make sure you have good balance.
RULES FOR SAFE OPERATION 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 safety warnings do not by themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident prevention measures. SYMBOL MEANING SAFETY ALERT SYMBOL: Indicates danger, warning, or caution. May be used in conjunction with other symbols or pictographs.
ELECTRICAL EXTENSION CORDS ELECTRICAL CONNECTION Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat.
