adjusting belt tracking

After a sanding belt has been installed, replaced,
or used for a significant amount of time, belt track-
ing adjustments are typically required. The belt
should track on the rollers so that the top edge of
the sanding belt stays parallel with the top edge of
the platen graphite.
Moving sanding belts are dangerously
abrasive. Use extreme caution when work-
ing near sanding surfaces. Use extreme
caution while making adjustments that
require momentary or extended operation
of the edge sander. Failure to exercise
care while sanding could result in severe
personal injury.
