Jet Air Flow

The air jet located at the air fork sends a stream of air across the air fork and into the air stream receiver (see Figure 18). As soon as the sanding belt obstructs this stream of air, a piston changes the direction of belt movement to the left. Your goal is to adjust this stream of air so the system uses the least amount of air and yet the machine still oscillates consistently and without delay.

To adjust the jet air flow, do these steps:

1.DISCONNECT THE SANDER FROM POWER.

2.Adjust the air regulator to 75 PSI.

3.Open both upper access doors on the sander, loosen the sanding belt tension, and slide the belt so the air stream is unobstructed.

4.Loosen the jam nut and turn the jet adjustment knob (Figure 19) clockwise until the air stream is reduced to a minimum.

5.Turn the jet adjustment knob counterclockwise, and use a piece of cardboard to alternately block and unblock the air stream until the upper drum just begins to react and move left and right.

6.Turn the jet adjustment knob counterclockwise an additional 1⁄2 turn and tighten the jam nut.

7.Now do the Belt Tracking procedure on Page 24.
