The Bald Buddy has an auto-shut-off function to protect the motor. The auto-shutoff function is activated when there is a build-up of hair/shaving cream in the blades/gears.
To test if your Bald Buddy is auto-shutting off, remove the shaving head and see if your shaver runs without the shaving head attached. If it does, follow the steps for deep cleaning your shaving head Deep Clean Link
