Section I. INTRODUCTION
This appendix provides a summary of the maintenance operations for the converter. It authorizes
categories of maintenance for specific maintenance functions on repairable items and components
and the tools and equipment required to perform each function. This appendix may be used as an aid
in planning maintenance operations,
B-2. MAINTENANCE FUNCTION
Maintenance functions will be limited to and defined as follows:
a. INSPECT. To determine the serviceability of an item by comparing its physical, mechanical,
and/or electrical characteristics with established standards through examination.
b. TEST. To verify serviceability and to detect incipient failure by measuring the mechanical or
electrical characteristics of an item and comparing those characteristics with prescribed standards.
c. SERVICE. Operations required periodically to keep an item in proper operating condition, i.e.,
to clean (decontaminate), to preserve, to drain, to paint, or to replenish fuel, lubricants, hydraulic
fluids, or compressed air supplies.
d. ADJUST. To maintain, within prescribed limits, by bringing into proper or exact position, or by
setting the operating characteristics to the specified parameters.
e. ALIGN. To adjust specified variable elements of an item to bring about optimum or desired
f. CALIBRATE. To determine and cause corrections to be made or to be adjusted on instruments
or test measuring and diagnostic equipments used in precision measurement. Consists of comparisons
of two instruments, one of which is a certified standard of known accuracy, to detect and adjust any
discrepancy in the accuracy of the instrument being compared.
g. INSTALL. The act of emplacing, seating, or fixing into position an item, part, module (com-
ponent or assembly) in a manner to allow the proper functioning of the equipment or system.
h. REPLACE. The act of substituting a serviceable like type part, subassembly, or module
(component or assembly) for an unserviceable counterpart.
i. REPAIR. The application of maintenance services (inspect, test, service, adjust, align, calibrate,
replace) or other maintenance actions (welding, grinding, riveting, straightening, facing, remachining
or resurfacing) to restore serviceability to an item by correcting specific damage, fault, malfunction, or
failure in part, subassembly, module (component or assembly), end item, or system.
j. OVERHAUL. That maintenance effect (service/action) necessary to restore an item to a
completely serviceable/operational condition as prescribed by maintenance standards (ie., DMWR)
in appropriate technical publications. Overhaul is normally the highest degree of maintenance performed
by the Army. Overhaul does not normally return an item to like new condition.
k. REBUILD. Consists of those services/actions necessary for the restoration of unserviceable
equipment to a like new condition in accordance with original manufacturing standards. Rebuild is the
highest degree of materiel maintenance applied to Army equipment. The rebuild operation includes
the act of returning to zero those age measurements (hours, miles, etc. ) considered in classifying Army
