4-29. GENERAL.
Organizational preventive maintenance checks and services are designed to help maintain radar set in serviceable
condition, prevent breakdowns, and ensure maximum operational capability. The PMCS procedures listed in this section
include (M) monthly and (Q) quarterly equipment checks.
The routine covering of unused receptacles; stowing of unused equipment; procedures such as equipment inventory,
cleaning of components, checking for frayed or broken cables; checking for loose hardware, nuts, bolts, and screws; and
touchup painting are not listed in the PMCS table. These are things you should do anytime you see they need to be
done. If you find a routine check in the PMCS table, it was listed because other technicians reported problems with this
item.
If equipment must be kept in continuous operation, check and service only those things that can be checked and serviced
without disturbing operation. Make complete checks and services when equipment can be shut down. If equipment fails
to operate, see the organizational troubleshooting steps in this manual. Use DA PAM 738-750 as a guide for reporting
problems and using forms.
The ITEM NO. column in the PMCS table is to be used as a source of item numbers for the TM number column on DA
Form 2404, Equipment Inspection and Maintenance Worksheet, for recording PMCS results.
NOTE
Keep in mind all warnings and cautions while performing PMCS or routine checks.
