how often preventative maintenance should be performed
Definition. Preventative maintenance (or preventive maintenance) is maintenance that is regularly performed on a piece of equipment to lessen the likelihood of it failing. Preventative maintenance is performed while the equipment is still working, so that it does not break down unexpectedly.Preventative maintenance is planned so that any required resources are available. The maintenance is scheduled based on a time or usage trigger. typical example of an asset with a usage based preventative maintenance schedule is a motor-vehicle which might be scheduled for service every 10,000km. Preventative maintenance is more complex to coordinate than run-to-failure maintenance because the maintenance schedule must be planned.
