If the battery is notto be used within 12 hours after initial filling, itshould be put on a charger and brought up tothe correct specific gravity. Test batteries asdeecribed in paragraph 4-25c, for the ambienttemperature in effect.(3.1) On ASK equipped generators, inspect ASK for damage.Check that exhaust plenum is clear of debris.Change 8 4-1
