INTRODUCTION
Preventive Maintenance Checks and Services (PMCS) are performed to keep the SHA and its associated
equipment in good operating condition. The checks are used to find, correct, or report problems. Operator
personnel are to do the PMCS jobs as shown in the PMCS table. PMCS are done every day the SHA is
operated, using the PMCS table. Pay attention to WARNING and CAUTION statements. A WARNING
means someone could be hurt. A CAUTION means equipment could be damaged.
Before you begin using the SHA, do Before PMCS
During use of the SHA, do During PMCS
After using the SHA, do After PMCS
Once a week, do Weekly PMCS if the SHA has been in use
Do Monthly PMCS once a month if the SHA has been in use
If you find something wrong when performing PMCS, fix it using troubleshooting and/or maintenance
procedures.
The right-hand column of the PMCS table lists conditions that make the SHA not fully mission capable.
Write up the faults that cannot be repaired on DA Form 2404 for unit maintenance. For further information
on how to use this form, see DA PAM 738-750.
If tools that are required to perform PMCS are not listed in procedures, notify your superior.
INSPECTION
Look for signs of trouble. Senses help here. You can feel, smell, hear, or see many problems that can be
eliminated before they get worse. Inspect to see if items are in good condition. Are components correctly
installed and secured? Is any damage to the frame or components visible? Correct any faults or notify unit
maintenance.
