or manuals that contain detailed repair or replacement procedures. If
the defect cannot be remedied by performing the corrective action

and reports of these checks and services must be made in accordance with
the requirements set forth in TM 38-750.

accomplished daily (or at least once each week if the equipment is
maintained in standby condition).

services that must be performed on a weekly, monthly, and quarterly
