Resumen del manual


Feed belt tension adjustment bolts. Note: Safety guard removed for clarity. 4. When tensioned properly you should not be able to lift the feed belt off the table surface or slide it back and forth. Awarning DO NOT sand boards with the guard removed. Failure to follow this warning could result in serious personal injury. NOTICE Adjust the feed belt tension before adjusting the feed belt tracking. To adjust the feed belt tracking: 1. Turn the feed belt ON. 2. If the feed belt is tracking to the right side of the table, turn the right adjustment bolt (Figure 26) clockwise. 3. If the feed belt is tracking to the left side of the table, turn the left adjustment bolt clockwise. Note: The edge of the feed belt should just touch the guide wheels as shown in Figure 27. Figure 27. Guide wheels. 4. Run the feed belt for 3-5 minutes and recheck the tracking. 5. If the belt is still tracking correctly, replace the safety cover removed in the previous subsection. G0446/G0539/G0571 37" Wide Belt Sander -31- Oscillation Timing When the oscillation is correctly adjusted, the sanding belt oscillates to the left and to the right at the same speed. If the sanding belt makes contact with a limit switch, as shown in Figure 28, the emergency braking system will activate and stop the sander immediately. To check the sanding belt oscillation: 1. Be sure the sanding belt is properly installed and the roller tension switch and air supply is 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 5, Page 33. 3. An adequate stream of air through the air fork gap (Figure 29) 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 29. Oscillation components. To set the correct amount of airflow through the air fork gap: 1. Remove the sanding belt and turn the roller tension switch to the tensioned position. 2. Loosen the lock nut on the airflow adjustment knob (Figure 30). 3. Turn the airflow adjustment knob 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. NOTICE The oscillation adjustments have been performed at the factory and should require no further attention. However, we recommend verifying the settings. —If the belt tracks away from the air fork and air jet, colliding into the limit switch, continue with Step 3. -32- G0446/G0539/G0571 37" Wide Belt Sander 5. Tighten the lock nut (Figure 30) to secure the airflow adjustment knob. s / / * Figure 30. 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. 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. —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 31) and move it to the left until proper tracking is achieved. Tighten down the oscillation adjustment knob when satisfied. Figure 31. Oscillation adjustment knob. —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 down the oscillation adjustment knob when satisfied. 8. Continue to the next page to adjust the oscillation speed. © G0446/G0539/G0571 37" Wide Belt Sander -33- 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 32). Figure 32. 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. 9- NOTICE The table has been adjusted at the factory and should require no further attention. However, we recommend verifying its parallelism with the sanding roller. The corners of the table can be independently adjusted up or down. By disconnecting the chain and turning the pertinent table elevation sc...
