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.
