3. 4. 5. Use the Pin Wrench to remove the Clamp Nut (8) Closely inspect the Grinding Wheel before mounting. Perform a ring-test on the wheel (unless wheel is smaller than 4” or is an unusual shape) as follows: a. Suspend wheel using a pin or finger through the arbor hole. Hang Wheel from Pin Tap Wheel Here 45° 45° V E R T I C A L C E N T E R 45° 45° b. Tap the flat side of the wheel with a light non-metallic object, such as a screwdriver handle, at a point 45° from the vertical center line on each side of the wheel and 1 – 2 inches from the edge of the wheel (see Illustration). c. Rotate the wheel 45 degrees and repeat the test until the entire wheel has been checked. d. An undamaged wheel will give a clear tone. If cracked, there will be a dead sound and not a clear ring. Slip the grinding wheel onto the Spindle with a paper gasket, or blotter, first. The blotter should be centered on the grinding wheel and the wheel and blotter should rest flat against the Inner Flange. 6. 7. WARNING: To prevent serious injury, blotters must be used for all grinding wheels they are provided with. Blotters help prevent grinding wheel damage and wheel slippage, causes of wheel failure. Thread the Clamp Nut onto the Spindle. Wrench tighten only enough so that the wheel is securely held on the spindle. WARNING: To prevent serious injury, do not overtighten flange. Overtightening can damage the wheel, causing wheel failure. Thread the Side Handle onto either side of the tool.
