If air lines are disconnected while under 90 to 125 psi (621-862 kPa), they can whip around and cause

injury or death to personnel. Air system should be drained and air bag control valve set in center position

before air bag air lines are disconnected.

PRESSURE TEST

(1) Move air bag control lever in the

down position (Para 2-9).

(2) Remove safety valve and T-fitting from

(3) Connect 0 to 160 psi (1103 kPa)

pressure gage to T-fitting.

(4) Connect air line 2224 to adapter on

T-fitting.

(5) While assistant raises air bag control

lever up, observe pressure gage.

(a) If safety valve releases at less

than 53-56 psi (365-386 kPa) or

95-100 psi (655-689 kPa) if

equipped with drawbar extension,

perform Steps (6) through (8)

below and adjust safety valve

(b) If safety valve releases at 53-56

psi (365-386 kPa) or 95-100 psi

(655-689 kPa) if equipped with

drawbar extension, safety valve

is OK.

(6) Lower air bag control lever.

(7) Remove pressure gage from T-fitting.

(8) Remove air line 2224 from adapter on

T-fitting.

(9) Install safety valve and T-fitting

on air bag.

VERIFY REPAIR

(1) Raise air bag control lever to up

position and observe drawbar

(a) If drawbar does not raise or

remain raised, fault not corrected.

Lower air bag control lever to

down position and notify

supervisor.

(b) If drawbar raises and remains

raised, fault corrected.

(2) Lower air bag control lever to

down position.
