Pressure Roller Tension
Pressure roller tension is the downward force that the pressure rollers place on the workpiece as it passes through the sander. Too little tension will cause the workpiece to pass unevenly through the sander and may launch the workpiece from the sander. Too much tension may cause poor and inconsistent sanding results, as well as premature wear on the conveyor belt and table.
To adjust the pressure rollers, do these steps:
1.MAKE SURE THE MACHINE IS DISCONNECTED FROM POWER and that you have set the pressure roller height.
2.Open both upper access doors and locate the four tension springs shown in Figure 11.
3.The position of the tension adjustment nut (Figure 11) controls the spring tension. Turn the nut clock- wise to increase the tension and counterclockwise to decrease the tension.
