1 Install pressure gauges of the test box in circuits 23 and 24 and test socket (3).
2 Depressurize the pneumatic system below the opening pressure of the circuits 23 and 24 and turn on the engine.
3 Before taking place a discharge (exhaustion) in pressure regulator, adjust the opening pressure of circuits 23 and 24 (4) in four-circuit protection valve (4.03).
It is possible to increase the pressure when tightening adjusting screws. It is possible to drop the pressure when releasing adjusting screws.
4 Repeat the check.
