Hold the workpiece firmly with both hands. Keep fingers
away from sanding belt. Keep the workpiece end
against the work support and move it slowly across the
sanding belt. Apply enough pressure to remove material;
excessive pressure will reduce sanding efficiency.

away from the sanding belt.
Keep the curve section of the workpiece pressed firmly
against the idler pulley and move it evenly back and forth
