Tools Needed: | Qty |
Phillips Head Screwdriver | ................................. 1 |
In order for the scale pointer to be accurate, it must be calibrated.
We recommend calibrating your scale pointer any time you adjust the drum height or table lift screws.
To calibrate the scale pointer:
1.Sand a workpiece with the drum sander and measure the thickness of the sanded workpiece.
2.Loosen the screw that secures the scale pointer and adjust it to the thickness of the workpiece.
