Lubricate more frequently to compensate for abnormal or
extreme conditions such as high or low temperatures,
prolonged operation, continued operation in sand or dust,
immersion in water, or exposure to moisture. Any one of
these conditions may cause contamination and quickly
destroy protective qualities of lubricants.
Intervals may be extended during inactive periods
commensurate with adequate preservation.
For lubrication instructions during continued operation
below 0°F (-18°C), refer to FM 9-207.
Refer to TM 9-238 for lubrication instructions before and
After operation in sandy or dusty conditions, clean and
inspect all lubrication points for fouled lubricants.
Change lubricants as required.
