Adjusting Drum Height & Drum-to-Conveyor Parallelism

The rear drum can be adjusted parallel to the conveyor belt in fine increments at the pillow bearings with the micro-adjust knobs, or the front drum can be adjusted parallel to the conveyor with the set screws on the pillow bearings. If, after performing the following procedure, you cannot adjust the drums parallel to the conveyor belt, it is possible that the conveyor table needs further adjust- ment. In that case, follow instructions on Page 43 for adjusting the table parallel to the drums at the table lift screws.

Keep in mind that having the drums parallel to the top of the conveyor belt (see Figure 54) is critical to the sand- ing operation. Take care to adjust the drums parallel to the conveyor surface within 0.002" from one side to the other.

To adjust the rear drum height and adjust the drums parallel to the conveyor belt, do these steps:

1.DISCONNECT POWER TO THE SANDER!

2.Open the top and pulley covers, remove the V-belts, and remove sandpaper from the drums for best results.

3.Place the gauge blocks (refer Page 32) on the con- veyor table and position them under the drums, as shown in Figure 55.

4.Raise the table up until the gauge blocks are approxi- mately 0.010" below the rear drum, checking with a feeler gauge. This setting will be used to determine rear drum-conveyor bed parallelism. Note: Each full turn of the table height handwheel raises the conveyor table approximately 0.020".
