Specifications include, but are not limited to: Level II Maintenance- Includes, checking the batteries for proper specific gravity, testing of the coolant (Coolant Analysis- Level 1) for proper concentration levels of antifreeze and conditioner, visual inspection of all vbelts, hoses and radiator core and piping. Contractor must start the generator and transfer the building load to check generator performance and switchgear operation; In addition contractor shall test the engine-related safety system for proper operation and SOS sampling of coolant. Level II maintenance will be performed once a year as required by facilities management. Level III Maintenance- Includes, engine oil, oil filters and fuel filters. Level III maintenance is designed by manufacture recommendations, SOS Sampling, allowing sampling to extend engine service intervals (typically no longer than three years). Level III maintenance will be performed once a year as required by facilities management. Contractor must use exact product or preapproved equivalent for filter replacements. Check engine coolant level, verify its temperature rating and take a sample and turn it in for analysis. Check all belts and hoses, tighten any loose belts, tighten coolant hose clamps (as needed). Verify operation of all Accessories, to see they are working correctly, these are coolant, and oil heaters, chargers, fuel tank systems, housing heaters, dip the diesel fuel tank with water finding paste, to verify no water buildup in tanks. Connect Electronic Technician software, and accomplish downloads , and as needed update software of all the ECM’s within the system to the most current for best operation., check all electric connection and tighten as needed . Clean control panel areas with a vacuum as needed. Will clean slip rings and brushes if equipped, or check and verify connection on rotating diode assemblies, also check generator circuit breakers and connections. Check oil, and fuel systems, verify fuel pressure, replace all fuel filters, oil filters and oil when required. Take samples which go to laboratory for testing, for oil, and coolant, fuel available at a separate cost. Check battery fluid level’s and condition, will top off with distilled water, as needed. Clean all battery terminals, and apply light coat of anticorrosion grease. Verify external battery charger working and that charging alternator is working. Inspect air intake, exhaust systems, and air filters. Start and run unit, with ET software monitor and test safety circuits to verify working as advertised, run unit verify proper VAC, and HZ. Wipe down equipment.
