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.
E: Air switch valve
The air valve is opened by pulling, and closed by pushing
