Attach a pressure gauge to the accumulator port on the brake valve.
Pump up the valve until you hear a characteristic click. The click is caused by the shifting of the spring and of the insert. The pressure should be between 16900 350 kPa (2450 50 psi) and 11900 350 kPa (1725 50 psi).
If the pressure is not correct, turn plug (6) in order to adjust the maximum accumulator pressure. Turn the plug clockwise in order to raise the high limit. Turn the plug counterclockwise in order to lower the high limit.
