RECOMMENDED MINIMUM WIRE GAUGE FOR EXTENSION CORDS (120 VOLT) NAMEPLATE AMPERES (at full load) EXTENSION CORD LENGTH 25’ 50’ 100’ 150’ 0–6 18 16 16 14 6.1 – 10 18 16 14 12 10.1 – 12 16 16 14 12 12.1 – 16 14 12 Do not use. TABLE A 9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table A shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. 10. WEAR PROPER APPAREL. Do not wear loose clothing, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain long hair. 11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting operation is dusty. Everyday eyePage 4 glasses only have impact resistant lenses, they are NOT safety glasses. 12. SECURE WORK. Use clamps or a vise to hold work when practical. It’s safer than using your hand and it frees both hands to operate tool. 13. DON’T OVERREACH. Keep proper footing and balance at all times. 14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. 15. DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits, cutters, and the like. 16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position before plugging in. 17. USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The use of improper accessories may cause risk of injury to persons. 18. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted. 19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function – check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard For technical questions, please call 1-800-444-3353. SKU 6510 or other part that is damaged should be properly repaired or replaced. 20. DIRECTION OF FEED.

Prepare to begin work before turning on the tool. 18. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure. 19. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead-based paints • Crystalline silica from bricks and cement or other masonry products • Arsenic and chromium from chemically treated lumber Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety Code § 25249.5, et seq.) 20. WARNING: Handling the cord on this product will expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling. (California Health & Safety Code § 25249.5, et seq.) SKU 6510 21. The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator. Vibration Safety This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury: 1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical checkups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any medical or physical symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible. 2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury. 3. Wear suitable gloves to reduce the vibration effects on the user. For technical questions, please call 1-800-444-3353. Page 7 4. Use tools with the lowest vibration when there is a choice between different processes. 5. Include vibration-free periods each day of work. 6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work. 7. To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration occurs, stop use immediately. Save these instructions.

Using the TOOL REST (7) as support, apply the dresser evenly to all surfaces of the GRINDING WHEEL. 4. Continue step 3 until the GRINDING WHEEL is straight and true. Dressing the Wheel New wheels frequently are not true and during operation often become grooved, glazed, out of round, or misshapen. At these times, they will need dressing. You will need a grinding wheel dresser for this operation. Dressers are available from Harbor Freight Tools. 1. Standing to the side of the wheel, let the Bench Grinder run for a full minute with no load. If the GRINDING WHEEL runs straight and true, you will not need to dress it prior to operating. If it is not, proceed with the following steps. Page 12 For technical questions, please call 1-800-444-3353. SKU 6510 OPERATION Caution: The grinding wheels must always be checked for cracks of imperfections. This is done with the “ring test”. Tap the wheel gently near the outer rim with the handle of a screwdriver; you should hear a clear belllike ringing. If a dull thud occurs do not use the wheel! This means the wheel has been damaged and will, most likely, come apart during normal operations. General Operation 1. Obtain a tray that is large enough for the workpiece to fit into, fill it with water and place it near the Bench Grinder. 2. Turn the Bench Grinder on. 3. Once the GRINDING WHEEL has reached full speed, bring the workpiece up to the wheel gently and without jarring. 4. Use the TOOL REST (7) to steady the workpiece. 5. The workpiece will become quickly heated. Frequently quench it in water. Operation Notes The 10” Bench Grinder comes assembled with a coarse GRINDING WHEEL (2) and a fine GRINDING WHEEL. Determine which wheel is which before attempting to use the Bench Grinder. The workpiece will quickly become heated. Frequently quench the workpiece in water during the grinding process. If the metal becomes heated so much that it gets blue-colored, it will be too soft to be useful. You must grind off the part that is colored, cool the workpiece, and start again.
