Task A – Emergency Generator Inspection, Testing and Maintenance (Monthly Tasks):

All tests, inspections and repairs shall be performed in accordance with the Cummins QSX15 Series Engine Operation and Maintenance Manual.

Exercise both generators for 30 minutes each at 30% load rating.

Check both generators for oil, fuel, cooling and exhaust system leaks. With the generator set operating, inspect the entire exhaust system visually and audibly including the exhaust manifold, muffler and exhaust pipe. Check for leaks in the exhaust system at all connections, welds, gaskets and joints and make sure that exhaust pipes are not heating surrounding areas excessively. Document and report any suspected leaks immediately. Check engine oil, coolant and battery electrolyte levels. Replenish fluids as necessary. With the generator set operating, inspect the fuel supply lines, return lines, filters and fittings for leaks. Check any flexible sections for cuts, cracks and abrasions and make sure that they are not rubbing against anything that could cause breakage. Note and report all leaks immediately.

Check and document the following while the generators are operating: frequency, AC Voltage at no load, AC Ammeter with no load. Check that all panel lamps are illuminating.

Check the terminals on the batteries and ensure all connections are clean and tight. Check and tighten battery vent plugs as necessary.
