When the swing and travel functions are operated, simultaneously the swing spool and travel spools
in the main control valve are moved to the functional position by the pilot oil pressure from the remote
control valve and the travel levers.
The oil from the P3 pump flows into the swing motor through the swing spool.
The oil from the P1 pump flows into the travel motor through the RH travel spool.
The oil from the P2 pump flows into the travel motor through the LH travel spool.
The superstructure swings and the machine travels straight.
