OPERATOR PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION
To ensure that the CB534B and CB534C Rollers, Motorized, Vibrating Tandem Steel Drums are ready for operation at all

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 the roller does not perform as required, refer to the appropriate troubleshooting procedure in Chapter
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 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 16, WP 0029 00) or two.
