Electric Motor Schematics

Where could I find the schematic for item number 47991 Chicago Electric power tool drill?

This is a 1/2″ Variable Speed Reversible Drill D-Handle 120V/60HZ/10/UL listed 908
E194601. I am trying to locate the screw that holds the chuck to the motor.

Good luck. With the Chinese stuff, you are lucky to get a users manual. Chicago Electric is Chinese made. Probably better off in the long run buying a new one. Contractors call these throw away tools…they break, you throw them away. Or invest in quality and get a Milwaukee or DeWalt.
