MAINTENANCE

FUNCTIONS

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 by measuring the mechanical or elec-

trical chacteristics 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 (includes decontaminate, when required),

to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical

fluids, or gases.

d. Adjust. To maintain, within prescribed limits, by bringing into proper

or exact position, or by setting the operating characteristics to specified

parameters.

e. Align. To adjust specified variable elements of an item to bring about

optimum or desired performance.

f. Calibrate. To determine and cause corrections to be made or to be

adjusted on instruments or test, measuring, and diagnostic equipment 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 (component or assembly) in a manner to allow the proper

functioning of an equipment or system.

h. Replace. The act of substituting a serviceable like type part, sub-

assembly, or module (component or assembly) for an unserviceable counterpart.

i. Repair. The application of maintenance services or other maintenance

actions

to restore serviceability to an item by correcting specific damage,

fault, malfunction, or failure in a part, subassembly, module (component or

assembly), end item, or system.

j. Overhaul. That maintenance effort (service/action) necessary to restore

an item to a completely serviceable/operational condition as prescribed by

maintenance standards in appropriate technical publications (i.e., DMWR).

Overhaul is normally the highest degree of maintenance performed by the Army.

Overhaul does not normally return an item to like new condition.

Services -- inspect, test, service, adjust, align, calibrate, or replace.

Actions -- welding, grinding, riveting, straightening, facing, remachining,

or resurfacing.
