Preventive Maintenance

a. Preventive maintenance is the systematic care, inspection and servicing

of equipment to maintain it in serviceable condition to prevent breakdown,

and to assure maximum operation efficiency. Preventive maintenance is the

responsibility of all categories of maintenance concerned with the equipment.

It includes inspection and repair of replacement of parts, subassemblies, or

units that inspection indicate would probably fail before the next scheduled

periodic service.

b. Maintenance forms and records to be used and maintained on the equipment

are specified in TM 38-750.

PREVENTIVE MAINTENANCE CHECK AND SERVICES (PMCS)

Section II.

PMCS Procedure

2-3.

Perform the maintenance functions indicated in the monthly preventive

maintenance checks and services chart (table 2-1) once each month unless

otherwise directed by the commanding officer. A month is defined as

approximately 30 calendar days of 8 hour-per-day operation. If the equipment

is operated 16 hours per day, the monthly preventive maintenance checks and

services should be performed at 15-day intervals. Adjustment of the maintenance

interval must be made to compensate for any unusual operating conditions.

Equipment maintained in a standby (ready for immediate operation) condition

must have monthly preventive checks and services. Equipment in limited storage

(requires services before operation) does not require monthly preventive

maintenance.
