Manny:
Parts diagram and parts listing can be found at the following site:
DeWalt & Delta Service Net
When the Service page opens, look on the left hand side a bit below the Large Word DeWalt, for a box with the words: Find It Now!
Enter your model number (40-601) and click on the small magnification icon.
You should be directed to a web page with three options. Ignore the 40-601R model.
BTW, Delta user manuals are not much to talk about, but I think you can download a PDF version of one from the site.
