GENERAL LUBRICATING INSTRUCTIONS UNDER UNUSUAL CONDITIONS 3-4. LUBRICATION FOR CONTINUED OPERATION BELOW 0°F (-18°C) a. Service Intervals. Service intervals on the lubrication instructions are for normal operation in moderate temperatures, humidity, and atmospheric conditions. b. Application Points. Wipe lubricating points and surrounding surfaces before and after applying lubricant. c. Reports and Records. Report unsatisfactory performance of lubricant or preserving materials on Product Quality Deficiency Report, SF 368, as stated in para. 1-4. a. Service Intervals. Increase frequency of lubricating service intervals when operating under abnormal conditions such as high or low temperatures, prolonged high-speed driving, or extended cross-country operations. Such operations can destroy lubricant’s protective qualities. More frequent lubricating service intervals are necessary to maintain vehicle readiness when operating under abnormal conditions. During inactive periods, with adequate preservation, service intervals can be extended. b. Changes in Lubricant Grades. Lubricant grades change with weather conditions. Refer to appendix G for lubricant grade changes. c. Maintaining Lubricant Levels. Lubricant levels must be checked as specified in appendix G. Steps must be taken to replenish and maintain lubricant levels. Refer to FM 9-207, Operation and Maintenance of Ordnance Materiel in Cold Weather (0°F to -65°F) (-18°C to -54°C), or appendix G. Lubrication instructions are in appendix G of this manual. All lubrication instructions are mandatory.
