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.
