opeartion:
main button:
a: internal pressure meter
b: air supply meter
c: air supply throttle
if the throttle whirls in clockwise, quantity of air input will be less, and oil input is less as well. Inverse, the input oil will increase.
D: governor valve
if the governor valve circumgyrate to the bottom, rate of oil pressure and air pressure is 100:1. For example, when air pressure 7kg, the oil pressure will be 700kg.
