MAINTENANCE
2-1.
Maintenance Concept. The grader will not require any special maintenance considerations. All maintenance
functions can be accomplished within the current maintenance concepts established for construction equipment.
a. Operator/Crew Maintenance: Operator/crew maintenance consists of daily checks, servicing and adjustments to
obtain and maintain a specific mission profile. Repair by operator/crew is limited to minor adjustments which do not
require disassembly.
b. Organizational Maintenance: Organizational maintenance will be accomplished by adjusting or replacing
accessible parts, assemblies and modules.
c. Direct Support Maintenance: Direct Support Maintenance will provide quick response to "on equipment" repairs
consisting of complete adjustment and replacement of designated parts, assemblies and modules to return the item to
operation ready status. Direct Support Maintenance will perform "off equipment" repair to designated assembled module
and by replacing special kits and authorized piece parts.
d. General Support Maintenance: General Support Maintenance will repair and return to the supply system
designated assembled modules which overflow from or exceed the capability of direct support maintenance. General
Support Maintenance will perform limited piece part repair and overhaul of selected major assemblies or components
designated by the area support command for return to stock.
e. Depot Maintenance: Depot maintenance overhauls end items and selected major assemblies when they are
required to satisfy overall requirements. Overhaul of the end item may also be performed by contract with the
manufacturer.
2-2.
Maintenance Allocation Chart: Maintenance will be performed as necessary by the category indicated in the
Maintenance Allocation Chart (}IAC) (Appendix C) to retain or restore serviceability. All authorized maintenance within the
capability of a using organization will be accomplished before referring the item to support maintenance. Higher categories
will perform the maintenance functions of lower categories when required or directed by the appropriate commanders.
Using and support units may exceed their authorized scope and function in the MAC when approval is granted by the next
higher support maintenance commander.
