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.
