8. Special Tools, Jigs and Fixtures Required. Not applicable.

9. Inspection Procedures. Only applicable to radar sets redeploying.

10. Cleaning Procedures.

a. Using a lint-free cloth, clean exterior surfaces of equipment and mechanical assemblies. Dampen cloth

(not wet) with warm sudsy water to remove ground-in dirt, grease, and fungus.

b. With a clean lint-free cloth and soft-bristled brush, clean plugs, jacks, and front panel controls and

indicators. Meter faces and front panels may be cleaned using a weak solution of water and mild soap.

Avoid excessive amount of solution on cloth and do not let solution enter behind controls or panel

mounting hardware of controls and indicators.

Clean exterior and pins of connectors of interconnecting cables with a brush. Cleaning compound may

be used with brush and cloth to remove grease, fungus, and light tarnish.

d. There are four air filters: one in bottom of receiver-transmitter, one in receiver side door of receiver-

transmitter, and one in bottom front of each pulse generator drawer. Tap edges of air filters to remove

as much dirt as possible. Wash air filters in warm sudsy water, using brush to remove dirt from wire

mesh. Allow filters to drain by supporting on suitable surface with airflow arrows on sides of filters

pointing upward.

e. Inspect/clean:

Receiver-Transmitter air-vent cover.

Radar Set Group - Air filters in bottom of receiver-transmitter and in receiver door

Control-Indicator Group - Air filters in bottom left front of both pulse generators (master and slave).

Receiver-Transmitter Internal Components - Open receiver and transmitter doors and clean. Control-

Indicator - Remove indicator access cover on side of shelter to expose control indicator and clean.

Clean reflective surfaces on antennas and covers on feedhorn and polarizer assemblies with soft, lint-

free cloth. Cloth may be used with weak solution of water and mild soap. Ground-in dirt, if necessary,

can be removed with a cloth dampened (not wet) with cleaning compound and used sparingly.
