. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed. ELECTRICAL SAFETY 4. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs.
11. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. 12. Avoid accidental starting. Be sure the Power Switch is off before plugging in. Carrying power tools with your finger on the Power Switch, or plugging in power tools with the Power Switch on, invites accidents. 13. Remove adjusting keys or wrenches before turning the power tool on.
21. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. 22. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool. SERVICE 23. Tool service must be performed only by qualified repair personnel.
7. Keep all Guards in place and in proper working order. 8. Remove adjusting keys and wrenches. Check to make sure all adjusting keys and wrenches are removed from this tool before turning it on. 9. Never attempt to remove material stuck in the moving parts of the Grinder while the tool is turned on, plugged in, or running. 10. Use light pressure when starting to grind. Too much pressure on a cold Grinding Wheel (40) can cause the wheel to crack. 11.
17. Industrial applications must follow OSHA requirements. 18. Maintain labels and nameplates on the Grinder. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 19. WARNING! People with pacemakers should consult their physician(s) before using this product. Operation of electrical equipment in close proximity to a heart pacemaker could cause interference or failure of the pacemaker. 20.
3. Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. (See Figure A.) THIS PRODUCT USES A 3-PRONG PLUG FIGURE A DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS 4. Tools marked “Double Insulated” do not require grounding.
EXTENSION CORDS 1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Figure C.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord.
