GENERAL.

a. Preventive maintenance is the systematic care, inspection, and servicing of equipment to maintain it in a

serviceable condition, prevent breakdowns and assure maximum operational capability. Preventive maintenance and

services of the RMHS Reference Gyro Set are established at the general support maintenance level and are performed

at daily, weekly, or monthly intervals, unless otherwise directed by the commanding officer or scheduled opera-

b. Maintenance forms and records to be used and maintained with this equipment are specified in DA Pam 738-750.

2-4. DAILY AND WEEKLY PREVENTIVE MAINTENANCE. Perform all the daily and weekly preventive maintenance

checks and services as outlined for the RMHS Reference Gyro Set. The step numbers in the PMCS outline indicate the

sequence of minimum inspection requirements. Defects discovered during operation of the unit will be noted for future

correction to be made as soon as operation has ceased. Stop operation immediately if a deficiency is noted during

operation which would damage equipment. Record all deficiencies together with the corrective action taken on the form

specified in DA Pam 738-750.

2-5. MONTHLY PREVENTIVE MAINTENANCE. Perform all the preventive maintenance checks and services listed

once each month in the sequence listed. A month is defined as approximately 30 calendar days of 8-hour-per-day

operation. If the equipment is not operated on a daily basis, adjustment can be made of the daily, weekly and monthly

preventive maintenance checks and servicing requirements.
