GENERAL
In addition to performing normal Preventive Maintenance Checks and Services (PMCS) (WP 0048), clean and
lubricate equipment more often to compensate for extremes of temperature, humidity, and terrain conditions
that are present or expected. Cleaned and lubricated equipment ensures proper operation and guards against
excessive wear and failure.
When equipment constantly breaks down due to operating under extreme conditions, report failure(s) using
DA Form 2404 (Equipment Inspection and Maintenance Worksheet).
