PMCS PROCEDURES

The following PMCS procedures are designed to prevent trouble for the equipment operator, and to assure

that the Surveying Level NA2-80 is ready when the operator is ready to work. Service intervals have been designed for

the operator to quickly check the readiness of the instrument to function perfectly. Possible defects that may be

encountered when performing the PMCS are indicated in the 'Equipment is Not Ready If:" column of Table 2-2 following.

If the operator can correct the problem, he should do so before starting on continuing operation.

Troubles requiring corrective action beyond the scope of the operator level maintenance must be reported,

and the equipment submitted to organizational maintenance.

The instrument should be kept clean. If telescope objective housing (Figure 1-2, item 4) and/or telescope

eyepiece (item 6) appear dusty or dirty, they may be cleaned with a dusting brush (Figure 1-5, item 5) or a lens tissue

and approved cleaning solvent.

CAUTION

Do not rub lens with cloth or fingers.

Operator PMCS procedures are indicated in Table 2-2.
