a. This section provides a general
explanation of all maintenance and
repair functions authorized at various
maintenance levels.
b. The Maintenance Allocation Chart
(MAC) in Section II designates overall
authority and responsibility for the
performance of maintenance functions on
PU 794/G.
It does not include the
generator set or trailer components
except modifications included in TM5-
6115-464-12 and TM9-330-205-14&P. The
application of the maintenance functions
to the end item or component will be
consistent with the capacities and capa-
bilities of designated maintenance
levels.
c.
Section III lists the tools and
test equipment (both special tools and
common tool sets) required for each
maintenance function as referenced from
Section II.
d.
Section IV contains supplemental
instructions and explanatory notes for a
particular maintenance function.
B-2. Maintenance Functions. Mainte-
nance functions will be limited to and
defined as follows:
a.

To determine the ser-
viceability of an item by comparing its
physical, mechanical and/or electrical
characteristics with established stan-
dards through examination (e.g., sight,
sound, or feel).
b. Test.
To verify serviceability by
measuring the mechanical, pneumatic,
hydraulic, or electrical characteristics
of an item and comparing those char-
acteristics with prescribed standards.
c. Service.
Operations required
periodically to keep an item in proper
operating condition, i.e., to clean
(includes decontaminate, when required),
preserve, drain, paint, or to replenish

optimum or desired performance.
f.
Calibrate.
To determine and cause
corrections to be made or to be adjusted

module (component or assembly) in a
manner to allow the proper functioning
of an equipment or system.
h.

To remove an unservice-
able item and install a serviceable
counterpart in its place.
“Replace” is
authorized by the MAC and is shown as
the third position code of the SMR code.

and maintenance actions to identify
troubles and restore serviceability to
