( 1 ) If the pressure will not drop below 3600 kPa (525 psi), the orifice plug may be missing.
( 2 ) Use a bench test to determine the pressure setting for this valve before you perform any adjustments.
( 3 ) The specification for this pressure depends on the ambient temperature. See the table in Testing and Adjusting, "Steering Accumulator - Test and Adjust".
