cracks in the insulation, bent or

his equipment keenly for any sign
of developing defects.
A locomotive operator, for example, observes the
instrument panel in the cab containing the various gages and controls. They
include air pressure gages, oil pressure gages in the engine lubricating
system, and water temperature gages.
Excessive deviations from normal
readings on the gages may point out deficiencies that could develop into
serious defects.
Section III.
Inspection and Maintenance Forms
2.19. GENERAL
Publications governing the inspection and maintenance of Army diesel-
electric locomotives require the use of various forms and records.
This
section contains only a general discussion of them.
For details on
preparation and distribution, the units responsible for inspecting and
maintaining the equipment must have the appropriate publications on hand and
follow the instructions therein.
Technical Manual 38-750, The Army
Maintenance Management System (TAMMS), and Technical Manual 55-202,
Operation and Maintenance of Diesel-Electric Locomotives, are the two
needed.
