1. When the right stabilizer control lever is pulled to the downward to set to the "EXTEND" position, the spool (5) of
the stabilizer LH control valve (2) moves to the right, which forms oil passage between bridge passage (4) and A4
port, and between 84 port and T port.
2.
The pressure-fed oil from the P port opens the load check valve (3), and flows to A4 port to retract the left stabilizer
cylinder.
3. Return oil from the left stabilizer cylinder returns to the transmission case through the B4 port, low pressure
passage and T port.
