a. General. Keep all lubricants in closed containers
and store in a clean, dry place, away from external heat.
Allow no dust, dirt, or other foreign material to mix with
the lubricants. Keep all lubrication equipment clean and
ready for use.
b. Cleaning. Keep all external parts not requiring
lubrication clean of lubricants. Before lubricating the
equipment, wipe all lubrication points free of dirt and
grease. Clean all lubrication points after lubricating to
prevent accumulation of foreign matter.

points at proper intervals as illustrated on LO 5- 3810-
232-12, -1, -2, -3, -4, -5, and -6.

failure or damage to working parts.
d. OES OiL
(1) The crankcase oil level must be checked
frequently, as oil consumption may increase.
(2) The oil may require changing more
frequently than usual because contamination by dilution
and sludge formation will increase under cold weather
operation conditions.
