The table lift screws are connected by a chain and driven by the crank handle. (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 set- ting the table parallel to the drum.)

Adjusting the table lift screws will only be neces- sary if you need to adjust the drum height more than allowed at the pillow block bearing adjust- ments, or if you have removed the table or chain (see Page 37) during a service procedure and you need to reset the drum parallel to the table.

Each complete tooth rotation on the sprocket represents 0.007" or .18mm of table elevation movement. For example, if the rear of the table was 0.007" low, rotate both rear table lift screws to the next sprocket tooth in the same chain posi- tion. You can easily rotate the sprockets from the top of the table lift screws with a flat head screwdriver.

To adjust the table lift screws:

1.DISCONNECT POWER TO THE SANDER!

2.Open the right side and front panels.

3.Raise the table up to at least the 1" mark on the height scale.

4.At the lift screw that needs to be adjusted, mark the end of a sprocket tooth and the chain hole where that tooth is meshed, as shown in Figure 37.

NOTICE

Marking the chain and sprocket locations will save you a substantial amount of time when you reinstall the chain. Make sure you have done this before removing the chain.

5.Loosen the chain by loosening the hex nut on the bottom of the idler roller sprocket shown in Figure 38.

6.Carefully move the chain off of only the marked sprocket.

7.Keep track of the marked chain hole and rotate the sprocket the necessary number of teeth away from the marked one to meet the difference in height needed.

8.Fit the chain back over the sprocket, making sure the new sprocket tooth is inserted into the marked chain hole.

9.Re-tension the chain and check the new height setting.

10.Repeat Steps 5–9as needed until the table height is parallel to the drums in all four cor- ners, tighten the idler sprocket and calibrate the scale pointer.
