PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
GENERAL
NOTE
Designated PMCS intervals are to be followed under usual
operating conditions. PMCS must be performed more frequently
when operating under unusual conditions.
Perform all checks and services per the designated intervals specified in the PMCS tables. Service
intervals are for normal operation of the bridge and pallet in moderate temperatures, humidity, and
atmospheric conditions. The intervals are hard-time intervals which are performed per the bridge's and
pallet age or calendar time. The hard-time intervals are based on calendar time. An example of a calendar
interval is semiannually (every six months).
EXPLANATION OF COLUMNS
The following is a list of the PMCS table column headings with a description of the information found in
each column.
a. Item Number. This column shows the sequence in which the checks and services are to be
performed, and is used to identify the equipment area on the Equipment Inspection and Maintenance
Worksheet, DA Form 2404/5988-E.
b. Interval. This column shows when each check is to be performed.
c. Location/Item To Check/Service. This column lists the location of the item to be inspected by
part, component, or assembly name.
d. Item to be Inspected/Procedures. This column identifies the general area or specific part where
the check or service is to be done and explains how to do it.
NOTE
The terms ready/available and mission capable refer to the same
status: equipment is on hand and is able to perform its combat
mission. Refer to DA Pam 750-8.
e. Equipment Not Ready/Available If:. This column lists conditions that make the equipment
unavailable for use because it is unable to perform its mission, or because it would represent a safety
hazard. Do not accept or operate equipment with a condition in the Equipment Is Not
Ready/Available If column.
REPORTING DEFICIENCIES
If any problem with the equipment is discovered during PMCS or while it is being operated that cannot
be corrected at the field maintenance level, it must be reported. Refer to DA Pam 750-8 and report the
deficiency on Equipment Inspection and Maintenance Worksheet, DA Form 2404.
