The platen is used to properly support the workpiece
when sanding. The platen is constructed of heavy steel
to provide adequate support.
Operating with the belt platen in place will allow the
operator to sand or grind straight, even lines.
The platen should be adjusted so the belt does not
contact the platen until work is fed into the belt.

remove belt cover.
Loosen socket head bolts and adjust belt platen
position.
Tighten bolts and secure platen.
Replace belt cover and tighten knobs.
