Aligning Pressure
Rollers
Two spring-loaded pressure rollers help maintain
consistent pressure on the workpiece as it passes
the sanding drum. The pressure rollers have been
set correctly at the factory. DO NOT adjust the
pressure rollers unless absolutely necessary.
When properly positioned, the pressure rollers
should be approximately 0.004" lower then the
sanding drum.
Adjusting the pressure rollers is a fine balance
between too much pressure and not enough. Too
much pressure can cause problems like snipe
or overloading the motor. Not enough pressure
may allow the workpiece to kick out of the sander
toward the operator.
