Preventive maintenance
Preventive maintenance is maintenance performed in an attempt to
avoid failures, unnecessary production loss and safety
violations.Proper identification of all the items, their
documentation and coding. Inspection of plant and equipment at
regular intervals. Proper cleaning and lubrication of equipments.
It helps to upkeep(reset) the machines through minor repairs.
Failures are analyzed in order to eliminate future

due to some failure or problem is termed as Breakdown of Machine.In
organizations, machines are attended only when the machine has
stopped functioning.Repair and corrective actions are taken up
after the problem has actually happened.

Maintenance Cost:
Because of breakdowns, both the machinery as well as the
manpower are left idle, per force. This results in production,
delay in schedules and emergency repairs.The downtime costs
generally exceed the preventive maintenance costs of inspection,
service and scheduled repairs.Downtime cost due to equipment
breakdown. Cost of spares and other material used for repairs. Cost
of maintenance labor and overheads of maintenance department.
Losses due to inefficient operations of machines. Capital
requirement for replacement of machines.
