What is maintenance ?

Maintenance is any any activities that is carried out in order to sustain the good working condition of any objects , machine or human .

 

What are the reasons for maintenance ?

  • To good the machine in good working condition
  • To increase the working life span of the object or machine
  • To avoid unnecessary wasteful spending on repairs
  • To reduce , prevent or eliminate accident

Types of maintenance 

  1. Predictive Maintenance : This type of maintenance is easily foretold and expected in order to keep the machine in optimal performance . Examples of such predictive maintenance is the regular change change of engine oil of a motor cycle or motor bike at least once in every fourteen days or proper tyre gauge of a motor vehicle
  2. Preventive Maintenance : Preventive maintenance is necessitated by the need to prevent the vehicle of machine from total collapses or breakdown . This is easily noticed when the vehicle starts making funny strange sounds . it is better that the vehicle is taken to the mechanic workshop to prevent breakdown of the machine
  3. Corrective Maintenance : This type of maintenance is always carried out when the deed had already been done . It is most undesirable because the machine is already down and this may affect productive use of time . The machine is already down , we just want to salvage or save what is left . Prevention is better than cure .
