2WD/4WD Changeover Valve
The 2WD/4WD changeover valve is located
below the radiator, behind the seat.
It controls 2WD/4WD operation. The hydraulic
circuit in the 2WD/4WD changeover valve is
switched according to the activation of the
solenoid valves.

Electro-Magnetic Check Valve
The electro-magnetic check valves are located
in cylinders #4 and #5.
When the traveling/working changeover switch
is working, it operates the solenoid valve by the
signal of the proximity sensor, stopping the
hydraulic circuit of the up cylinder in the
working position.
