A good maintenance is essential to keep machines and work environment
safe and reliable.
According to the European Standard EN 13306,
maintenance concerns the "combination of all
technical, administrative and managerial actions
during the life cycle of an item intended to retain
it in, or restore it to, a state in which it can
perform the required function".

 To maintain mc equipment at optimum operation speed &
production efficiency
 To ensure best possible level of quality of product.
 To minimize the idle time resulting from the machinery break
down.
 To reduce the cost.

Importance of Maintenance
 To increase the life time cycle of machinery & equipment
 In case of appropriate functioning.
 Better or superior quality for the product.
 Higher productivity of machines
 Wastage reduces & control.
 Economization of the process.

 Due to proper maintenance reduce undue worn out of different parts &
equipment as well as corrosion of the items & increase the machines life (
these are the result of routine cleaning, lubricating, repairing, replacement,
fitting, & refitting etc.)
 For sound or congenial operation of machinery, it is required the proper
lubrication, fitting, repairing, & replacement (as per necessity).
 By the continuous operation of the machinery reduces stoppages time
resulting better quality & less wastage

Plant Failure Analysis
 Incorrect assembly or installation of machine parts
 Incorrect operation (load, temperature, speed, input, output)
 Improper selection and application of lubrication systems
 Poor design or component quality

OPERATION INVOLVED in MAINTENANCE
Setting: Setting is the activities to set or install the machine parts or
required ancillaries. Adjustment also complementary word to setting
used for appropriate setting.
Checking: Checking means investigation of machine condition. It is
very important work in case of maintenance. It is very skilled depends
work as successful maintenance that depends on correct fault
detection.
Repairing: Repairing or altering of spares & equipment (if necessary)
is to be detected & necessary measures are taken
(repairingalteringsettingadjustment) .
Overhauling: It is the work of maintenance, but not frequent or
schedule work. It is done as per as necessary
