3-1. Scope of Operator’s Maintenance
Following is a list of maintenance duties normally
performed by the OE-254/GRC operator. These
procedures do not require special tools or test equipment.

3-3. Operator/Crew Preventive Maintenance
Preventive maintenance is the systematic care, servicing,
and inspection of equipment to prevent the occurrence
of trouble, reduce downtime, and assure
that the equipment is operational.
a. Systematic Care. The procedures given in table
3-1 cover routine, systematic care and cleaning essential
to proper upkeep and operation of the equipment.
b. Preventive Maintenance Checks and Services.
The preventive maintenance checks and services
chart (table 3-1) outlines functions to be performed
daily. These checks and services are to maintain
Army electronic equipment in a combat-serviceable
condition; that is, in good general (physical) condition
and in good operating condition. To assist operators
in maintaining combat serviceability, the chart indicates
when to check, how to check, and the normal
conditions. The for readiness reporting, equipment is
not ready/available if column lists the criteria when the
OE-254/GRC is classified as not ready for its primary
mission. If the defect cannot be remedied by the
operator, higher category maintenance or repair is
required. Records and reports of these checks and
services must be made in accordance with the
requirements set forth in DA Pam 738-750.
3-4. Preventive Maintenance Checks and Services
Periods
Preventive maintenance checks and services (PMCS)
of the OE-254/GRC are required on a daily/weekly
basis. Table 3-1 specifies checks and services that
must be accomplished under the conditions listed
below.
a. During. Be sure to perform during (D)
procedures each day the antenna is installed.
b. Weekly Procedure. If the equipment was not
checked during the week, perform the D PMCS
together with the weekly (W) PMCS.
c. If Your Radio Equipment Fails to Operate.

NOTES
Routine checks are not listed as PMCS;
such as: cleaning (para 3-5); checking for
frayed cables; stowing items not in use;
covering unused receptacles; checking for
loose nuts and bolts. These are things that
should be done anytime you see they must
be done.
The Item No. in table 3-1 shall be used as
a source of item numbers for the TM
number column on DA Form 2404 (Equipment
Inspection and Maintenance
Worksheet) in recording the results of the
PMCS.
If the equipment must be kept in constant
operation, check and service only those
items that can be checked and serviced
without disturbing operation. Make complete
checks and services when the equipment
can be shut down.
