Replace both WHEEL COVERS (6) 5. and secure with their BOLTS (12), NUTS (13), and WASHERS (14). 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. Standing to the side of the wheel, let 1. 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. With the Bench Grinder running, grip 2. the handle of the dresser firmly with one hand and the arm of the dresser with the other. Using the TOOL REST (7) as sup3. port, apply the dresser evenly to all surfaces of the GRINDING WHEEL. Continue step 3 until the GRINDING 4. WHEEL is straight and true. 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 bell- like 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. 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 pr...
