. 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.
22. 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. 23. 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 24. Tool service must be performed only by qualified repair personnel.
7. Always maintain a 1/16” distance or less between the Grinding Wheels (part #64) and Left and Right Tool Rests (parts #28, #32) as the diameter of the Grinding Wheels decrease with use. 8. To avoid accidental electrical shock, do not allow the Power Switch (part #3) to become wet. Do not touch the Power Switch with wet hands. 9. When using the Bench Grinder, always maintain a firm grip on the object being ground with both hands. 10.
22. Always turn off the Bench Grinder and unplug it from its electrical outlet before changing accessories or performing any inspection, maintenance, or cleaning procedures. 23. WARNING! The warnings and cautions discussed in this manual cannot cover all possible conditions and situations that may occur. It must be under stood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied the the operator. 24.
2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically “live” terminal. (See Figure A.) 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 that in the following illustration.
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, next page.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord.
