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 than the 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 towards the operator.

To.check.pressure.rollers,.do.these.steps:
1.
DISCONNECT MACHINE FROM POWER!
2.
Place gauge blocks on feed belt, as shown in
Figure.43
.
3..
Raise table until blocks just touch the rear pressure
roller.
4.
Find the largest size feeler gauge that can pass
between sanding drum and your gauge block. (The
feeler gauge should slide with moderate resistance,
without forcing drum to roll.)
— If gap is 0.004" (0.1mm) or less, then no
adjustment of rear pressure roller is necessary.
— If gap is more than 0.004" (0.1mm), then rear
pressure roller must be adjusted.
5.
Raise table until gauge blocks just touch the drum.
6.
Find the largest size feeler gauge that can pass
between the front pressure roller and your gauge
block. (The feeler gauge should slide with moderate
resistance, without forcing the drum to roll.)

. Example of gauge blocks placed
under drum.
— If the gap is 0.004" (0.1mm) or
less, then no adjustment of front
pressure plate is necessary.
— If the gap is more than 0.004"
(0.1mm), then front pressure plate
must be adjusted.
