a. General. This section contains the procedures and instructions necessary to perform unit PMCS. These

services are to be performed by unit maintenance personnel with the assistance, where applicable, of the operator/crew.

Your PMCS is performed to find and fix problems before they cause major damage to the equipment. Perform the

PMCS in the order listed.

b. PMCS Procedures. Refer to Table 4-1.

This column is used as a source of item number for the "TM Number" column on DA Form 2404, Equipment Inspection

and Maintenance Worksheet, in recording results of PMCS.

these instructions. If you do not have the tools or if the procedures tell you to, have direct support maintenance do the

work.
