Figure 20. This is the oscillation

timing control knob.

5.When you get the belt to oscillate without stopping, experiment with the timing knob to see the effect its movement has on the belt oscillation.

6.Position the timing knob so the belt moves from one side to the other, back and forth, in even intervals.

7.Lock the knob in place by turning it clock- wise.

Long term exposure to this machine during operation may cause

hearing loss. Wear approved hearing pro- tection to minimize this risk!

Oscillation Speed

Use the valve shown in Figure 21 to control the speed of the sanding belt oscillation. Make sure the oscillation is balanced before adjusting the speed.

Figure 21. Use the knob on this valve to control

oscillation speed.

Keep loose clothing out of the way of moving machinery and keep long hair pulled back.

To increase the oscillation speed, open the valve (turn the knob counter-clockwise). For nor- mal operation, adjust the oscillation speed so each direction of belt movement takes approxi- mately 2 seconds. When the speed is correct, tighten the jamnut so the knob will not move.

To decrease the oscillation speed, close the valve (turn the knob clockwise). When the speed is correct, tighten the jamnut.

Different speeds may yield different finishing results. Experiment with trial-and-error to deter- mine the best speed for your particular situation.
