TM 5-6115-593-12 TO 35C2-3-463-1 CHAPTER 4 ORGANIZATIONAL MAINTENANCE Section I.  SERVICE UPON RECEIPT OF EQUIPMENT 4-1. UNLOADING THE GENERATOR SET. WARNING Use  the  slings  provided  and  a  lifting  device  with  a capacity  of  20  tons  (18,000  kg).    Do  not  allow  the generator    set    to    swing    while    it    is    suspended. Failure    to    observe    this    warning    may    result    in serious injury or death to personnel. 4-2. INSPECTION AND SERVICING THE EQUIPMENT. a. Inspection. (1) Inspect radiator for damage. (2)   Inspect radiator fan drive belt for proper tension (figure 4-1). Code A. (3)   Check that pulley guard and vibration damper guard are secure. (4)   Inspect all air cleaner connections for tightness. (5)   Inspect the fuel, water, and coolant lines for cracks and leaks. (6)   Inspect  that  the  cooling  system shut-off    cock    (figure    4-2)    is closed    and    the    three    engine water   drain   points   (figure   4-3) are closed. (7)   Make certain that the crankcase drain is closed (figure 4-4). (8)   Inspect that fuel tank drain cock (figure 4-5) is closed. (9)   Make a thorough visual inspection of the entire generator set and accessories for loose or missing mounting hardware, fuses, bulbs, or damaged or other missing parts. Report all damaged or missing parts. b. Servicing. WARNING Do  not  smoke  or  use  an  open  flame in the vicinity when filling fuel tank. (1)   Fill fuel tank with appropriate fuel.  (See Appendix B for quantity and type of fuel required.) (2)   Fill radiator with arctic antifreeze solution in accordance with table 4-1. WARNING Do not smoke or use an open flame in the vicinity when servicing batteries. Batteries generate a highly explosive hydrogen gas during charging. Electrolyte is sulfuric acid diluted with water and can cause severe acid burns when spilled on skin or clothing.  Use extreme care in handling while servicing batteries.  When servicing batteries reference TM 9-6140-200-14. (3)   Batteries are shipped in a dry state. Battery electrolyte must be requisitioned separately. See table 3-1 for quantity and electrolyte stock number.  To activate the battery, remove cell caps and fill battery cells 3/8 inch (9.5 mm) above plates with electrolyte.  Make sure vent holes in cell caps are open, and replace caps.  The electrolyte level must be rechecked approximately 30 minutes after initial filling as the plates and separators will absorb the solution, thus resulting in 4-1
