Section I. INTRODUCTION
This appendix provides a summary of the maintenance operations covered in the equipment literature for Test
Sets AN/GGM-15(V)f and AN/GGM-15(V)2. 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 Functions
Maintenance functions will be limited to and defined as follows:
a. Inspect. To determine serviceability of an item by comparing its physical, mechanical, and electrical
characteristics with established standards.
b. Test. To verify serviceability and to detect incipient electrical or mechanical failure by use of special
equipment such as gages, meters, etc. This is accomplished with external test equipment and does not include
operation of the equipment and operator type tests using internal meters or indicating devices.
to charge, and
to add fuel, lubricants, cooling agents and air.
If it is
desired that elements such as painting and lubricating be defined separately, they may be so listed.
d. Adjust. To rectify to the extent necessary to bring into proper operating range.
e. Align. To adjust two or more components or assemblies of an electrical or mechanical system so that
their functions are properly synchronized. This does not include setting the frequency control knob of radio
f. Calibrate. To determine the corrections to be made in the readings of instruments or test equipment
used in precise measurement. Consists of the comparison 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 with the certified standard.
g. Install. To set up for use in an operational environment such as an encampment, site, or vehicle.
h. Replace. To replace unserviceable items with serviceable like items.
i. Repair. To restore an item to serviceable condition through correction of a specific failure or unservice-
able condition. This function includes, but is not limited to welding, grinding, riveting, straightening, and re-
placement of parts other than the trial and error replacement of running spare type items such as fuses, lamps,
or electron tubes.
j. Overhaul. Normally, the highest degree of maintenance performed by the Army in order to minimize
time work in process is consistent with quality and economy of operation. It consists of that maintenance
necessary to restore an item to completely serviceable condition as prescribed by maintenance standards in
technical publications for each item of equipment. Overhaul normally does not return an item to like new, zero
mileage, or zero hour condition.
k. Rebuild. The highest degree of material maintenance. It consists of restoring equipment as nearly as
possible to new condition in accordance with original manufacturing standards. Rebuild is performed only when
required by operational considerations or other paramount factors, and then only at the depot maintenance
category. Rebuild reduces to zero the hours or miles the equipment, or component thereof, has been in use.
