Belt Oscillation Speed

For normal operations, the oscillation speed should be set so that it takes approximately a second or two to complete each direction of travel; however, you can experiment with different speeds to see how the results may affect your finished product. Often, you may find that certain speeds yield better results for different varieties of stock and the feed rates chosen.

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

To set the belt oscillation speed, do these steps:

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

1.Complete the Belt Tracking adjustments on Page 24.

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.If you have not already done so, turn the sander

ON.

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

OPERATIONS

4.

Looking from the front of the sander, observe the

Figure 21. Oscillation speed knob.

 

left-to-right motion of the belt as it moves along the

 

 

drum.

 

 

—If the oscillation is very sluggish (streaks are

 

 

appearing on the workpiece), or the oscillation is

 

 

very fast (less than a second), loosen the jam nut

 

 

on the air valve and adjust the knob to restrict or

 

 

apply more air to adjust the oscillation speed.

 

5.

When you get the speed between 1-2 seconds,

 

 

tighten the jam nut.

 

6.

Observe belt tracking and oscillation, and repeat

 

 

the Belt Tracking procedure on Page 24 or the Jet

 

 

Air Flow procedure on Page 23 if needed.
