Improper oscillation. To check the sanding belt oscillation: 1. Be sure the sanding belt is properly installed and the belt tension knob and air supply are ON. 2. Turn ON the sanding belt. —If the belt oscillates without contacting the limit switches, but the oscillation time to the left and right are NOT equal, proceed to Step 7, on Page 31. 3. An adequate stream of air through the air fork gap (Figure 26) is essential for proper oscillation. If the jet of air is weak through the gap, the belt will track away from the controller and into the limit switch on the opposite end of the roller. The pivot action of the upper roller, and the resulting oscillation of the belt, are dependent upon adequate airflow through the air fork gap. Figure 26. Oscillation components. To set the correct amount of airflow through the air fork gap: 1. Remove the sanding belt and turn the belt tension knob to the tensioned position. 2. Loosen the lock nut on the airflow adjustment knob (Figure 27). 3. Turn the airflow adjustment knob (Figure 27) clockwise until the airflow is completely OFF. The upper roller should pivot to the right. 4. Slowly turn the airflow adjustment knob counterclockwise, and continue turning up the air pressure until the roller pivots to the left. -If the belt tracks away from the air fork and air jet, colliding into the limit switch, continue with Step 3.

However, we recommend verifying the settings. -30- M G0445/G0582/G9962Z/9962ZX Wide Belt Sander w 5. Tighten the lock nut (Figure 27) to secure the airflow adjustment knob. 6. Restrict the airflow across the air fork gap with a scrap piece of wood. You should notice the roller pivot to the right. When the stick is removed, the roller should pivot back to the left. —If the oscillation time to the right is 2 seconds, but the oscillation time to the left is longer, loosen the oscillation adjustment knob (Figure 28) and move it to the left until proper tracking is achieved. Tighten down the oscillation adjustment knob when satisfied. 7. Test the oscillation by running the sander. Make note of the time it takes for the belt to oscillate from left-to-right and from right-to-left. When correctly timed, the oscillation should take a similar amount of time to oscillate. Figure 28. Oscillation adjustment knobs. —If the oscillation time to the left is 2 seconds, but the oscillation time to the right is longer, loosen the oscillation adjustment knob and move it to the right until proper tracking is achieved. Tighten the oscillation adjustment knob when satisfied. 8. Continue to the next page to adjust the oscillation speed. G0445/G0582/G9962Z/9962ZX Wide Belt Sander mb -31- Oscillation Speed Table Parallelism The oscillation speed of the sanding belt is adjustable. Different oscillating speeds yield different sanding results. We recommend trying various speeds on a scrap piece of wood similar to the final workpiece. To adjust the oscillation speed: 1. Loosen the lock nut on the speed control adjustment knob (Figure 29). Figure 29. Speed control adjustment knob. 2. Turn the knob clockwise to decrease the oscillation speed and counterclockwise to increase it. 3. Tighten the lock nut loosened in Step 1 to secure the knob. NOTICE The table has been adjusted at the factory and should require no further attention. However, we recommend verifying that it is parallel with the sanding roller. The corners of the table can be independently adjusted up or down. Table parallelism can be achieved by disconnecting the chain and turning the pertinent table elevation screw sprocket (Figure 30). Adjusting the table parallelism can be a very tedious task that takes a great amount of patience. DO NOT adjust the table unless you are having trouble sanding your workpiece to a uniform thickness. If a table adjustment is needed, take precise notes on the positioning of the table elevation screws. This will allow the original setting to be re-established. Figure 30. View of elevation screw sprockets. -32- H G0445/G0582/G9962Z/9962ZX Wide Belt Sander W To adjust the table parallelism: Pressure Rollers 1. Pass a 24" wide board through the sander until the entire surface of the board is making contact with the sanding belt. 2. Measure the thickness of the board at various points around the edge. 3. If there is a variation of thickness, the table can be adjusted accordingly. 4. DISCONNECT THE SANDER FROM THE POWER SOURCE! —For minor adjustment, loosen the table mounting bolts shown in Figure 31 and rotate the elevation screw flange. —For major adjustment, mark the chain location on all sprockets, remove the chain from the sprocket to be adjusted, and turn the sprocket counterclockwise to raise the table. One quarter of a turn raises or lowers an elevation screw approximately 0.0...
