HELPFUL TIPS
• If the sanding belt slips or does not track while sand-
ing, you may be applying too much pressure. When
this occurs, remove the sander from the workpieoe.
I_,ou properly adjust the belt tracking, the sanding belt
will return to its normal and correct position on the
drive roller and front roller,
• Use a coarser sanding belt for heavy sanding, r_ol
heaw pressure. The weight of the tool is sufficient to
provide adequate pressure at the correct location.
• The front roller of the sander is not designed for con-
tour sanding. Sanding on the front roFler could cause
irregularity in the sanding belt tracking.
