37. Preventive Maintenance
Preventive maintenance is the systematic care, servicing, and
inspection of equipment to prevent the occurrence of trouble, to
reduce downtime, and to assure that the equipment is serviceable.
a. Systematic Care. The procedures given in paragraphs 39, 40,
and 41 cover routine systematic care and cleaning essential to
proper upkeep and operation of the equipment.
b. Preventive Maintenance Checks and Services. The preventive
maintenance checks and services charts (pars. 39 and 40) outline
functions to be performed at specific intervals. These checks and
services are to maintain Army electronic equipment in a service-
able condition; that is, in good general (physical) condition and
in good operating condition. To assist operators in maintaining
serviceability, the charts indicate what to check, how to check,
and what the normal conditions are. The References column lists
the paragraphs that contain detailed repair or replacement pro-
cedures. If the defect cannot be remedied by the operator, higher
echelon maintenance or repair is required. Records and reports of
these checks and services must be made in accordance with the
requirements set forth in TM 38-750.
38. Preventive Maintenance Checks and Services Periods
Paragraph 39 specifies checks and services that must be accom-
plished daily. Paragraph 40 specifies additional checks and serv-
ices that must be performed once each week.
