EH <br />Sales and <br />Service <br />PLANNED MAINTENANCE CHECKLIST <br />STANDARD INSPECTION <br />Below is the scope of work performed during the above planned maintenance checklist. Any additional repairs, parts, or service which <br />are required will be brought to the attention of the owner. Repairs will only be made after proper authorization from the owner is given <br />to Cummins Sales and Service. Any additional repairs, maintenance or service performed by Cummins Sales and Service for a <br />Planned Maintenance Agreement holder will be at Cummins Sales and Service labor rates. <br />A. PRE -OPERATIONAL CHECKS <br />1. All equipment automated, no alarms or faults on controls <br />2. Check fluid levels and observe for leaks. Oil, Fuel and <br />Coolant <br />3. Verify battery chargers, component heaters and accessories <br />are operational <br />4. Safety Audit, Lock Out/ Tag Out Procedures Followed, Safe <br />Service Operations <br />B. BATTERIES AND BATTERY CHARGER <br />1. Check battery charger functions and record voltage and <br />current <br />2. Cable connections, termination cleanliness and security <br />3. Check electrolyte level, vent caps and specific gravity of all <br />cells in the starting battery system <br />3.a Record highest and lowest specific gravity measured. <br />4. Perform Battery load test on all starting batteries and record <br />cca, ambient temperature, float volts, hold volts, and if the <br />battery passed or failed testing. <br />C. ENGINE COOLING SYSTEM <br />1. Inspect all hoses and clamps for leaks and condition <br />2. Inspect radiator cap and filler neck condition <br />3. Inspect drive belts, observe alignment and deflection <br />4. Confirm proper coolant heater operation and record jacket <br />water temperature <br />5. Verify Coolant properties and record the freeze point, DCA <br />concentration, PH level, Sulfates, Chlorides, and <br />appearance. <br />6. Inspect radiator surfaces, shrouds and barriers for <br />obstruction, build up and mechanical damages <br />7. Verify LTA coolant properties and record the freeze point, <br />PH level, and appearance (if applicable) <br />8. Optional coolant sampling <br />D. GENSET CONTROLS AND ACCESSORIES <br />1. Check all engine mounted wiring, senders and devices <br />2. Check all control mounted components and wiring <br />3. Check all connecting plugs <br />4. Check all accessory components and wiring <br />5. Function test lights and indicators <br />E. MAIN ALTERNATOR <br />1. Remove covers and inspect terminals, wiring and component <br />2. Visually inspect main rotor and stator <br />3. Visually inspect exciter components and PMG (where <br />equipped) <br />4. Manually operate generator main breaker(s) open and <br />closed <br />F. FUEL SYSTEM <br />1. Check main and secondary (if applicable) tank fuel and <br />record levels <br />2. Check day tank fuel and record level (if applicable) <br />3. Check day tank controls and pumps. Test operate day <br />tank controls where available (if applicable) <br />4. Check all fuel hose, clamps, pipes, components and fittings <br />5. Check fuel pressure and record readings running and loaded <br />6. Check governor linkage (if applicable) <br />7. Water in Fuel Test - Sub -base, day tanks or as noted on <br />agreement <br />8. Rupture/ Containment Basin Inspection (if applicable) <br />G. INTAKE AND EXHAUST SYSTEMS <br />1. Check air cleaner element <br />2. Check intake system <br />3. Check exhaust system and rain cap <br />4. Check louver operations (if applicable) <br />H. ENGINE AND LUBRICATION SYSTEM <br />1. Check lubrication system <br />2. Check crankcase ventilation system <br />3. Check spark ignited ignition system (if applicable) <br />I. GENERATOR OPERATIONS <br />1. Start and observe generator and equipment operations <br />2. Verify engine and generator safeties as applicable <br />K. TRANSFER SWITCH/ SWITCHGEAR <br />1. Inspect all power and control wiring <br />2. Inspect switch mechanism and enclosure <br />3. Inspect controls and time delay settings <br />4. Check exercise clock <br />5. Verify remote start control operation <br />6. Measure and record utility/ source one voltage <br />L. SYSTEM OPERATIONAL TESTS <br />1. Genset test with or without load, if not allowed document <br />decision maker <br />2. During test without load record engine oil pressure, oil <br />temperature, coolant temperature, battery voltage, engine <br />speed, exhaust temperature, coolant pressure, blowby flow, <br />LTA temperature. Also record generator voltage on all <br />phases, frequency, current on all phases, load PF, load KW <br />Load KVA, and Load KVAR. <br />3. Record duration of system test in minutes <br />M.
