PREFACE
A new machine/equipment will provide satisfactory service if kept in proper operating condition. The inevitability of less than 100% reliability of any machine/equipment after some period and maintenance.
Also in system of any complexity, certain replacement adjustments are necessary at various stages. Thus a vital consideration in the design of the system components and requirement of a system in the question of how quickly and easily a unit in that system can be adjusted or repaired.
Repair or rehabilitation simply means to restore to good condition, to be in a new form or to renovate.
The repair and rehabilitation of machine in the Mechanical engineering workshop Laboratory of this institute is of utmost importance considering the members of machine that are less or non-functional.
Its quite unlike a couple of years back when it was an easy talks to recommend newly produced machine.
The habit of replacement of damaged or faulty machine(s) with new once rather than repairing them should be discouraged.
The ownership of these machine/equipment should be a never ending source of satisfaction and pleasure and so, effort should be made to reactivate them.
Historically, repair/equipment has tended to be an emergency service performed in am ad-hoc faction and largely concerned with getting broken-down machine beck into service as soon as possible.
These shouldn’t have been so, rather repair/rehabilitation should be done thoroughly and perfectly. Unfortunately, the climate in West Africa course rapid deterioration I all metal objects; machine and tools are no exception.
