Safety continues to be the priority at Dahle, and the DAHLE CleanTEC?????? 41330 shredder features the most advanced safety features in the industry. Equipped with the revolutionary Safe Technology Package, each shredder offers Verbal and Contact Emergency Shutdown. In the event of an emergency, simply say "Stop" or tap the top cover of the machine, and the shredder immediately stops. The 10 1/4" feed opening is reinforced with steel and only large enough to accept paper. As an added safeguard, this opening contains electronic sensors that will turn the shredder off, should your fingers get too close. An emergency shutoff switch is also located on the back of the machine as yet another level of personal safety.
