The document defines maintenance as keeping physical plant and equipment in good operating condition. It discusses the objectives of maintenance as minimizing downtime and costs while ensuring quality. The document outlines five types of maintenance: breakdown, preventive, predictive, routine, and planned. Preventive maintenance aims to minimize unexpected interruptions through inspection, servicing, and repairs. Predictive maintenance uses instruments to monitor equipment and predict issues. Proper maintenance is important for organizations to reduce costs, ensure quality, and minimize breakdowns.

7. A. BREAKDOWN MAINTENANCE
OCCURS WHEN THERE IS A
WORK STOPPAGE DUE TO
MACHINE BREAKDOWN
MAINTENANCE BECOMES
REPAIR WORK
SEEKS TO GET THE EQUIPMENT
BACK INTO OPERATION AS
QUICKLY AS POSSIBLE

8. B. PREVENTIVE MAINTENANCE
• It is undertaken before the need arises and aims
to minimize the possibility of un -anticipated
production interruption or major breakdowns.

9. PREVENTIVE MAINTENANCE:
is undertaken before the need arises and aims to minimize
the possibility of un-anticipated production interruptions
or major breakdowns.
It consists of:
• Proper design and installation of equipment
• Periodic inspection of plant and other
equipments
• Repetitive servicing and overhaul of equipment
• Adequate lubrication, cleaning and painting

10. C. PREDICTIVE
MAINTENANCE:
• In this, sensitive instruments
(e.g., vibration analyzers,
amplitude meters, audio gauges,
optical tooling and resistance
gauges) are used to predict
trouble. Conditions can be
measured on a continuous basis,
and this enables the maintenance
people to plan for an overhaul.

11. D. ROUTINE
MAINTENANCE:
this includes activities such
as periodic inspection,
cleaning, lubrication and
repair of production
equipment after their service
life.

12. E. Planned maintenance:
it involves the inspection of all plant and equipment,
machinery, buildings according to a predetermined
schedule in order to service overhaul, lubricate or repair,
before actual break down or deterioration in service occurs.

13. CONTROL OF MAINTENANCE
• Authorized by an official
• Maintenance schedule
• Issue materials against proper authorization
• Maintenance budgets
• Equipment records

14. ISSUES:
How much
maintenance is
needed?
What size maintenance
crews must be used?
Can maintenance be
sub-contracted?
Should maintenance
staff be covered by
wage incentive
schemes?
Can effective use be
made of computers for
analyzing and
scheduling activities?

15. Benefits of
Proper
Maintenance:
Greater Safety
Decreased Production DownTime
Fewer large Scale & Repetitive Repairs
Less Cost for Simple Repairs
Less Standby Equipment Required
Better Spare parts Control
Proper Identification of Items

16. CONCLUSION:
• TO ENSURE EFFECTIVE IMPLEMENTATION OF ACTIVITIES, IT IS
IMPORTANT THAT THE PRODUCTION FACILITIES NEED TO BE
MAINTAINED IN GOOD WORKING CONDITION.
• REDUCES COST, MACHINERY BREAKDOWN, ETC.
• QUALITY ASSURANCE
THEREFORE, MAINTENANCE MANAGEMENT IS AN IMPORTANT
ASPECT FOR ANY ORGANIZATION.
