Contractual Maintenance

In this system an outside personnel or agency will come and repair the equipment whenever called. This outsider may be the original Equipment Manufacturer (OEM) or a consultancy or experienced personnel or an agency.

Usually this system is adopted:

• On machines which do not interrupt the production line at all, e.g. type machines, time card punching machines, computers, etc.
• If it is cheaper to get repaired by an outsider than in-house repair.
• If the repairing needs high skill, knowledge and technology or special accessories or measuring instruments.
• The machines on which breakdown rarely occur.
• To the machines which are under guarantee/warrantee period.
• As a temporary arrangement when PEM becomes handicapped due to some problems like insufficient manpower or unavailability of required spares in the open market, etc.
• By sub-contracting or making service contracts due to heavy work load in PEM and wasting the experience of the maintenance personnel is not at all advisable for repair work of smaller jobs which could be done by sub-contractor. For instance the winding of motors, repair of valves, etc. will be usually given to sub-contractors for this reason.
