Preventive Maintenance

A routine service of the A.C. generator involves occasional cleaning, lubrication of the bearings and possibly an insulation resistance check on the windings of the machine, especially, if it has run for a considerable amount of time. Both interior and exterior of the machine should be kept free from any oil or dust by blowing out frequently (Say every 3 months) with clean dry air at a pressure not-exceeding 3.5 kg/cm2. If blowing is in-effective to remove oil or dust, the parts should be carefully cleaned with a rag lightly damped in white spirit or get it overhauled and re-varnished by rotating machine service center.
