When the arm regeneration is selected to disable on the cluster, the arm regeneration solenoid 
valve is activated. The pilot oil from pilot pump flow into Pb4 port in main control valve through 
solenoid valve and the arm regeneration spool is shifted to left.
Then, the oil from arm regeneration passage returns to tank and the arm regeneration function is 
deactivated.
When the arm regeneration is selected to enable on the cluster, the arm regeneration function is 
activated and arm in operation speed is increased.
Refer to page 3-37 for the arm regeneration function.
