Cannot tighten then belt on a skil 594 belt sander

SOURCE: belt sander adjustment

There should be a knob on the front of the sander which adjusts the front roller on the sander. If the belt runs off in the same direction each time try turning the knob as the sander is running and while watching the belt. If turning the knob one direction does not work try turning the other direction. If turning the knob does not have any affect on the way the belt tracks on the sander then you probably have a broken or missing part on the front of the sander. This may require taking the sander to a service center.

All sander will have two adjustments. The first is to release the sanding belt by retracting the position of one of the rollers. The second adjustment moves one of the rollers belt tension from side to side. The roller angular position is changed, sometime by a single knob or screw, and sometimes by two separate adjusting screws.

There should be a tracking adjustment knob on the side of the sander behind the front roller. Run the saw and adjust this knob to center the belt. You will probably have to do this every time you change belts. Hope this helps you...

There is a leveling (screw/knob) on the side of the belt sander. Turn it up and the belt will drift in one direction. Turn it downward and the belt will drift in the opposite direction. play with this leveling screw/knob until you reach a good balance and the belt will stop drifting.
