must do the procedure at the time stated in the interval column.
e. Equipment is Not Ready/Available if: Column. Information in this column tells you what faults will keep
your equipment from being capable of performing its primary mission. If your check and service procedures show

Other Table Entries. Be sure to observe all special information and notes that appear in your table.
The forms and records you fill out have several uses. They are a permanent record of the services, repairs and
modifications made on your equipment. They are reports to unit maintenance and to your commander. They are also
a checklist for you when you want to know what is wrong with the equipment after its last use and whether those faults
have been fixed. For information on forms and records, see DA Pam 738-750.

warnings.
d. If something does not work, troubleshoot it with the instructions in this manual and notify your supervisor.

report it to unit maintenance RIGHT NOW!
