Adjusting secondary opening pressure a. In the event that the measured value devi- ates from the specified limit, readjust the primary opening pressure if the amount of deviation is small. (to the standard range of the primary opening pressure) - If the secondary opening pressure is lower than the standard value: Adjust the primary opening pressure up to the top limit of the standard vague, and then measure the secondary opening pres- EQM4040I sure. - If the secondary opening pressure is higher than the standard value: In a reverse manner, readjust the primary opening pressure down to the bottom limit of the standard value. b.
If the secondary opening pressure still deviates from the specified limit in spite of 10 the readjusting the primary opening pres- sure, take off the nozzle fixing portion from the nozzle holder and remove the adjusting shim (10). c. If the secondary opening pressure is high- er than the standard value, fit a thinner adjusting shim than the existing one. EQM4058I d. After replacing the existing adjusting shim, measure the secondary opening pressure and continue the adjustment until a value satisfying the standard value.
