5.Raise the table until the gauge blocks just touch the drum.

6.Find the largest size feeler gauge that can pass between the front pressure plate and your gauge block. (The feeler gauge should slide with moderate resistance, without forc- ing the drum to roll.)

—If the gap is 0.004" (0.1mm) or less, then no adjustment of the front pressure plate is necessary.

—If the gap is more than 0.004" (0.1mm), then the front pressure plate must be adjusted.

1.Disconnect power to the sander!

2.Loosen the lock nuts and tighten the cap screws on both ends of the rear pressure plate shown in Figure 46 to raise the pres- sure plate, or loosen the cap screw to lower the pressure plate.
