When the equipment is suspended, it needs to resume normal use at any time. If maintenance is not carried out during the suspension period, abnormality may occur during recovery, so the equipment should also be maintained during the suspension period. Only in this way can normal use be resumed at any time.
Maintenance is not required only if the equipment is sealed or scrapped. If the equipment is idle or scrapped due to equipment aging or product or process adjustment, the equipment can be scrapped and sealed.
