W1772/W1773 37" Drum Sander
Scale Pointer Calibration
For the scale pointer to be accurate, it must be calibrat- ed.
We recommend calibrating your scale pointer any time you adjust the drum heights or table lift screws.
To calibrate the scale pointer, do these steps:
1.Sand a workpiece with the drum sander and measure
the thickness of the sanded workpiece. | Figure 61. Scale pointer screw. |
2.Loosen the screw that secures the scale pointer and adjust it to the thickness of the workpiece.
Dust Scoops
The dust scoops and metal scoop plates are correctly positioned on the top cover at the factory, however these may loosen and move during shipping. Some trial and error will be needed to adjust the dust scoops so they do not contact the sanding drums.
To adjust a dust scoop, do these steps:
1.DISCONNECT POWER TO THE SANDER!
2.Remove the handwheel and open the pulley cover.
3.Loosen the button head cap screws and acorn nuts securing a metal scoop plate to the top cover
(Figure 62), move the scoop up a little, tighten the cap screws and nuts, close the top cover, and rotate the V-belt to see if the drum srapes the scoop.
4.Adjust each scoop in this manner until the sanding drums do not scrape the scoops, then close the pul- ley cover and reinstall the handwheel.
Table Lift Scews
The table lift screws are connected by a chain and driven by the table elevation handwheel. When the chain is removed from a sprocket on one of the lift screws, that lift screw can adjust that portion of the table up/down independently to assist in setting the table parallel to the drums.
Adjusting the table lift screws will only be necessary if you need to adjust the drum heights more than allowed at the pillow bearing adjustments, or if you have removed the table or chain during a service procedure and you need to reset the drums parallel to the table.
