Figure 25.
This is one of the four
pressure roller adjustment bolts.
Pressure roller tension is largely set by trial and
error. If there is not enough tension, the work-
piece will not pass through the sander evenly and
may possibly be launched toward the operator. If
there is too much tension, the feed belt will expe-
rience premature wear and the workpiece will
pass through the sander sluggishly (if at all).

A quick way to gauge that the spring tension is
consistent is to measure the distance from the top
of the nut to the the top of the adjustment bolt. If
the board pulls to one side during sanding, loosen
that side in small increments as needed.
