Notify higher level of maintenance if terminals,cables, batteries or frame is damaged.c.Service.NOTEThe 6TN and 6TL batteries can be mixed ormatched. However, maintenance-free batteriescannot be mixed or matched with militarybatteries. The 6TN and 6TL batteries will performproperly in bot weather as long as electrolyte levelsare carefully monitored. If the electrolyte expandsand causes the level to rise, some fluid must beremoved. If tbe level becomes too low due toevaporation, distilled water may be used to obtainthe proper level. A good grade of drinking water(excluding mineral water) may be used if distilledwater is not available.3/8 inch above top of plates. Check that battery caps are not loose.Electrolyte (NSNs6810-00-249-9354 and6810-00-843-1640) have a specific gravity of 1.280and should be used in these batteries. Do NOTadjust the electrolyte in wet batteries to a lowerspecific gravity.(1) Fill batteries (6) with clean distilled water to a levelof 3/8 inch above top of plates. In freezing weather, run engine aminimum of one hour after adding water.3-12.GROUND ROD AND FUEL DRUM ADATPERHOLD-DOWN ASSEMBLY.a. Removal (see figure 3-9).
