To remove the rotor lift motor (don't touch the enameled wire)

Clear on rotor commutator (that is in contact with the carbon brush), if it is too dirty or wear much can use emery cloth first grinding water sand paper or metallographic sandpaper to light again

Before and after the rotor in the bearing is sealed if can wipe clean can outside, shall promptly replace if seal is broken. In front of the rotor helical gear shaft wipe clean

Inside the shell of smeary clean wipe clean

The drill chuck lever on both ends of helical gear and bearing (or bush) the wipe clean

Put off the east back, first rotor; Reload drill chuck rod helical gear; With carbon brush and carbon brush if shorter than 7-8 mm to timely change new. Carbon brush to flatten packed
