Use personal protective equipment: wear safety goggles, dust mask, protective gloves, etc., to avoid metal fragments splashing and inhalation of dust. Check before operation: ensure all the press brake and surrounding tools lie in a common state. The die is stable and its setting is correct. Correct loading the materials: avoid single-hand operation, using professional tools position and fix the sheet, in order to avoid sheet sliding or popping during bending. No overburden operation: obey the maximum loading restriction of the equipment strictly, thus preventing the machine from damage or human injury because of overloading. Equipment maintenance: maintain and check the press brake regularly, eliminating faults and hidden dangers promptly. Safety training: all the operators must be trained with professional safety regulations, and know the equipment functions and emergent measurements under emergent situations.
