Belt Tracking

OPERATIONS

The belt tracking knob and lever (Figure 20) stops the belt from tracking off of the drums and shutting down the machine. Your goal is to position the belt tracking lever so the belt tracks in the center of the drums and the left-and-right belt movement takes a similar amount of time.

KEEP your hands clear of the sanding belt when making these adjustments!

To set the belt tracking, do these steps:

Note: Since each adjustment effects the other two slightly, you may have to repeat or fine-tune the Belt Oscillation Speed and the Jet Air Flow adjustments after you do this procedure.

1.Complete the Jet Air Flow adjustment on Page 23.

2.Put on safety glasses, tie back all loose clothing, remove jewelry, pull back sleeves, and tie back long hair so it will not get caught by the sanding belt.

3.Turn the sander ON.

4.Observe the left-to-right motion of the belt as it moves along the drum while looking from the front of the sander.

—If the belt tracks faster to one direction than the other, loosen the belt tracking knob and slightly move the lever and retighten the knob. Through a process of trial-and-error you will be able to adjust this lever so the belt tracks at a similar rate from right-to-left and left-to-right. This tracking will occur between the ceramic limit switch levers.

5.Keep the sander running, and now complete the Belt Oscillation Speed adjustment as outlined on

Page 25.

KEEP loose clothing and long hair secured and away from moving parts.
