(10) Remove coupling (14), coupling (21), elbow

(25), elbow (26), elbow (27), and four reducers

(28) from air manifold (7).

(11) Remove coupling (29), and elbow (30) from

l. Air Pressure Regulators Adjustment

CAUTION

Windshield washer/city horn air

pressure regulator must be adjusted

to 30 psi (207 kPa). Modulator air

pressure regulator must be adjusted

to 70 psi (483 kPa).

NOTE

Arrows on back of air pressure

regulator point in direction of air flow.

(1) Attach 0-1000 PSI pressure transducer (1) to air

pressure regulator outlet port (2).

(2) Attach air supply hose (3) to air pressure

regulator inlet port (4).

(3) Pull knob (5) to unlock air pressure regulator (6).

(4) Adjust air pressure regulator (6) to proper air

pressure using STE/ICE Test 50 (TM 9-4910-

571-12&P). Turn knob (5) clockwise to increase

regulator pressure or counterclockwise to

decrease regulator pressure.

(5) Push in knob (5) to lock air pressure regulator

(6).

(6) Remove air supply hose (3) and pressure

transducer (1) from air pressure regulator (6).
