Page 24: Checking Drum Alignment
Double Drum Sander 37 x 2 Checking Drum Alignment CHECKING DRUM ALIGNMENT: Unless the machine was stressed during shipment, only fine adjustment should be necessary. Minor alignment corrections can be done without relieving V-belt tension or adjusting the tension rollers but should be done without any abrasive strips attached. - Page 25 Machine Set-Up Before altering this conveyor table position, also check to see that the rear drum is likewise parallel to the conveyor table, with both sides at the same height above the table. Using the same thickness gauge, check both sides of the rear drum from the rear of the machine while holding up the rear tension roller.
- Page 26 Double Drum Sander 37 x 2 Note: The nut of the rear bolt on the rear (secondary) drum bearing bracket should be backed off a quarter-turn from being fully tightened. This allows the lock washer to be depressed slightly but not completely. This is the pivot point for the rear drum.
- Page 27 Machine Set-Up NOTE: Adjust the take-up screw nuts only 1/4 turn at a time. Then allow time for the belt to react to the adjustments before proceeding further. Try to avoid over-adjustments. Make sure wrench is below surface when sanding. **NOTICE!** Important: Before using the height adjustment, be sure to loosen both the set screws located on the front of both table support castings (See Figure 3 and Figure 11) to allow the table support to slide on both column tubes.
- Page 28 Double Drum Sander 37 x 2 Check the operation of the height adjustment mechanism. If it does not operate smoothly or easily, further adjustments may be necessary. Refer to the servicing section of this manual, which begins on page 53 for further adjustment procedures.
