MAINTENANCE INSTRUCTIONS

Section I. PREVENTIVE MAINTENANCE

CHECKS AND SERVICES (PMCS)

3 1. General

To insure that the type B-7 life preserver is ready for operation at all

times, it must be inspected systematically so that defects may be

discovered and corrected before they result in serious damage or

failure. The necessary preventive maintenance checks and services to

be performed are listed as described in paragraph 3-2. The item

numbers indicate the sequence of minimum inspection requirements.

Defects discovered during operation of the life preserver will be noted

for future correction to be made as soon as operation has ceased.

Stop operation immediately if a deficiency is noted during operation

which would damage the equipment if operation were continued. All

deficiencies and shortcomings will be recorded together with the

corrective action taken on DA Form 2404 (Equipment Inspection and

Maintenance Worksheet) at the earliest possible opportunity.
