Install a pressure gauge at the pressure port by the outlet of the master cylinder.2. Start the engine and observe the pressures at which the charge valve operates. Minimum pressure cut-in should be 6890 to 7580 kPa (1000 to 1100 psi) and maximum pressure cutout should be 10 300 to 10 680 kPa (1500 to 1550 psi).3. If the charging limits are not within the limits stated above, remove plug (3) with an allen wrench.4. Using the same allen wrench, rotate plug (4) clockwise to raise both limits or counterclockwise to lower both limits.5. When the pressures are within the limits, replace plug (3).
