Abstract – The objective of the work is to improve the preventive maintenance schedule, increase the avaibility of machines, saving of total down time & production cost as compared to the current maintenance. The work is carried out in the industry manufacturing the parts of the refrigeration & air-conditions, where the operations like spinning, cutting to appropriate length, shaping & testing of these part are performed. The work is planned initially to find the all breakdown occurred with their frequency of occurrence, after that it is analyzed by the tools FMEA.This helps to develop and improve a new preventive maintenance checklist for the machines. This method is used to prevent the failure of equipment before it actually occurs. The work is finally leads to reducing sudden breakdown and increasing availability machines. This has been achieved by optimal utilization of time for maintenance, inspection frequency by considering manufacturer recommendation and previous experience. By all these procedures the availability of the machine will increases to a certain extent and also increases the production capacity, minimizes the maintenance cost and Reduces the down time.
