The Army Maintenance System MAC - Continued
To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics of an item
and comparing those characteristics with prescribed standards on a scheduled basis, i.e., load testing of lift devices
and hydrostatic testing of pressure hoses.
Operations required periodically to keep an item in proper operating condition; e.g., to clean (includes decontaminate,
when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical fluids, or gases. This includes
scheduled exercising and purging of recoil mechanisms. The following are examples of service functions:
To remove from packing box for service or when required for the performance of maintenance operations.
To return item to packing box after service and other maintenance operations.
To spot paint scratched or blistered surfaces.
To restore obliterated identification.
To maintain or regulate, within prescribed limits, by bringing into proper position, or by setting the operating
characteristics to specified parameters.
To adjust specified variable elements of an item to bring about optimum or desired performance.
To determine and cause corrections to be made or to be adjusted on instruments of 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.
To remove and install the same item when required to perform service or other maintenance functions. Install may
be the act of emplacing, seating, or fixing into position a spare, repair part, or module (component or assembly) in
a manner to allow the proper functioning of an equipment or system.
