[Standard Loading Pressure - Setting Pressure Chart Lines]
The setting pressures corresponding to the loading pressures are shown below. As slight deviations
from the "loading pressure - setting pressure" chart lines shown below may occur depending on
conditions such as the length of the air line, etc., a setting pressure which is high enough to cover such
deviations should be selected.
