2. What is maintenance?
• Maintenance is the processes of keeping machine and equipment in good working condition
so that the efficiency is retained and its life increased.
• Its a combination of actions carried out by organization, to replace, repair, service the
machines, components or their groups in a manufacturing plant, so that it will continue to
operate satisfactory.
• Maintenance is defined as a function manufacturing management that is concerned with day
to day problems of keeping the physical plant in good operating condition.

Functions of Maintenance
1. Inspection
- Periodic checking of machines
- Giving proper attention to those equipments required work in
intervals
- Determination of repair feasibility
- Control of quality work
- Detection of faults before break down of equipment
2. Repair
- Process of repairing the component or replasing the item or part
by another item to restore failed or broken down item in working order.

Functions of Maintenance - cont.
3. Overhaul
- Falls preventive maintenance
- Frequency of overhauling is less than lubrication and inspection
4. Lubrication
- Helps in maintaining the machine accuracy and increase life of
machine
- It is done by the operator itself
-Lubrication can be daily, weekly, forthnightly, montly

Types of Maintenance
1. Preventive Maintenance
2. Breakdown Maintenance

9. 5/2/2021
Types of Maintenance
1. PREVENTIVE MAINTENANCE
Involves performing maintenance activities before the equipment
fails. This activity includes regular inspection, machine adjustments,
lubrication, cleaning and parts replacement
Objectives:
 To reduce frequency and severity of interruptions to production caused
by machine malfunction
 To detect potential problems earlier and avoid the associate cost

Types of Maintenance - cont.
2. BREAKDOWN MAINTENANCE
Involves performing maintenance activities after a machine
breakdown or malfunction has occured and then must be repaired on an
emergency or priority basis.
Breakdown maintenance includes repairs, replacement of parts or
even overhaul to ensure the machine is put back in operating condition.

Importance of Maintenance
 Maintenance can avoid work stoppage and ensure the lost of production
time and cost or minimized
 To keep the entire production system running smoothly with minimum
interruption
 To avoid loss of sales and profits
 Help reduce production cost such as idle labor cost and overtime cost

Importance of Maintenance - cont.
 To ensure that the entire work place is a safe place to work for its
employees
 To established a competitive edge and to enhance good customer service
 To ensure that the product meet the expected quality and specifications
 To reduce cost of breakdown and repairs

ADVANTAGES AND
DISADVANTAGES OF
MAINTENANCE

15. 5/2/2021
ADVANTAGES OF MAINTENANCE
• Life of machinery and equipments are increased
• Production takes place as per the schedule
• Products are delivered to customers in time and hence high level of customer satisfaction
can be expected
• Machines are in good condition. Hence quality of the products will be good
• No production loss
• Machinery is not damage
• No idle time of men and machines. Hence their utility increases

16. 5/2/2021
DISADVANTAGES OF MAINTENANCE
• Machinery may be damaged. This is a loss.
• Poorly maintained machines will produce poor quality products.
• More wastage of materials
• Breakdown of machines makes both men and machine in idle position. So
production time is wasted. This will increase cost of production.
• Poor maintenance cost accidents.
• Due to poor maintenance life of machine is reduce
