The control panel on the Porter PFM-4000 is located in the metal control box mounted under the tabletop on the sewing motor. This box manages all system functions. For safety, do not open the control box yourself, as it poses an electrical hazard. Only an authorized service technician should open it. Use the external controls as instructed in the machine’s manual; internal components should not be accessed by the user.
