To ensure that the Crew Protection Kit is ready for operation at all times, it must be inspected on a regular basis so that
defects may be found and corrected before they result in injury or death due to equipment failure.
The PMCS Table in WP 0009 00 contains systematic instructions on inspections and services to be performed by the
operator to keep your equipment in good operating condition and ready for its primary mission.
EXPLANATION OF TABLE ENTRIES
Item Number (Item No.) Column. Numbers in this column are for reference. When completing DA Form 2404 or DA
Form 5988-E (Equipment Inspection and Maintenance Worksheet), include the item number for the check/service indi-
cating a fault. Item numbers also appear in the order that you must perform checks and services for the interval listed.
Interval Column. This column tells you when you must perform the procedure in the procedure column.
Before procedures must be done immediately before you operate vehicle with Crew Protection Kit installed.
After procedures must be done immediately after operating vehicle with Crew Protection Kit installed.
Weekly procedures must be done once each week.
Location, Item to Check/Service Column. This column provides the location and item to be checked or serviced.
The WARNINGs and CAUTIONs appearing in your PMCS table should always be observed. WARNINGs
and CAUTIONs appear before applicable procedures. You must observe these WARNINGs to prevent
injury or death to personnel, and CAUTIONs to prevent your equipment from being damaged.
Procedure Column. This column gives the procedure you must perform to check or service the item listed in the Item
to Check/Service column, to know if the equipment is ready or available for its intended mission. You must perform the
procedure at the time stated in the interval column.
Not Fully Mission Capable If: Column. Information in this column tells you what faults will keep your equipment
from being capable of performing its primary mission. If you perform check/service procedures that show faults listed in
this column, the equipment is not mission-capable. Follow standard operating procedures for maintaining the equipment
or reporting equipment failure.
GENERAL PMCS PROCEDURES
Always perform PMCS in the same order so it gets to be a habit. Once you've had some practice, you'll spot anything
wrong in a hurry.
If anything looks wrong and you can't fix it, write it on your DA Form 2404 or DA Form 5988-E. If you find something
seriously wrong, IMMEDIATELY report it to your supervisor.
Before performing preventive maintenance, read all the checks required for the applicable interval and prepare all that is
needed to make all the checks. You'll always need a rag (Item 6, WP 0032 00) or two.
