Its dedicated Auto Feed hopper can take an impressive 175 sheets at one time in its ample 11" x 17" opening. Simply load the paper, press start, and let the FD 8502 do the rest. No more standing around waiting to feed small stacks of paper manually. This shredder's impressive performance is made possible by the AC geared motor with heavy duty steel gears. There is also the heat treated steel cutters that are specially ground for long life with minimal oiling required. All of these components are housed in an all steel cabinet with built in casters and a heavy duty waste bin that's guaranteed for life.
