SEISO (Scrub-Clean and Check)
SEISO is cleaning and also checking. Clean the working environment, including machines and tools, floors, walls and other areas of the shop floor, because when the machine is covered with oil, soot and dirt, it is difficult to identify any problem that may be developing.
It is understood that most machines go under breakdown due to vibration, or wear debris or introduction of foreign particles or due to inadequate lubrication. SEISO is a great learning experience for the operators of the machine, since they can make many useful innovations regarding the cleaning of the machines. Naked electrical wires may be covered safely while cleaning the machine.
