6.0 Setup and assembly 2. Install three spacers onto each end of arbor. 3. Check the flanges to make sure they are clean and flat. Wheel flanges that are not flat will cause the wheel to wobble. 4. Install inner flange, buffing wheel, and outer flange. 5. Install a nut on each end of arbor and tighten with 15/16”, or adjustable, wrench. The brasscolored nut has left-hand threads – install on left end of arbor and tighten counterclockwise.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician. extension cord becomes necessary, use only threewire extension cords that have three-prong grounding type plugs and three-prong receptacles that accept the tool's plug. Replace or repair damaged or worn cord immediately. Improper connection of the equipment-grounding conductor can result in a risk of electric shock.
Always use approved safety glasses or face shield while operating buffer. Also use appropriate respiratory protection. 8.1 General procedure 1. Turn on buffer and apply compound to lower part of spinning wheel (not the workpiece). Do not apply excessive compound; press compound stick lightly against wheel for only a few seconds. Reapply later as needed. 2. Grip workpiece firmly and press it against underside of wheel, that is, the area of wheel that is rotating away from the workpiece. See Figure 8-1.
9.2.1 Adjusting concentricity 4. If the outside face is not rotating concentric to arbor, try shifting the wheel closer to arbor centerline before tightening the nut. If required, a shim made of paper or card stock may be placed between flange and wheel side. Continue this combination of flange movements until the wobble is eliminated. NOTE: Slight wobble may still exist at spin-up and spin-down, but will not affect normal speed operation.
