When the swing and bucket functions are operated simultaneously, the swing spool and bucket
spool in the main control valve are moved to the functional position by the pilot oil pressure from the

The oil from the A1 pump flows into the swing motor through the swing spool in the left control valve.
The oil from the A2 pump flows into the bucket cylinder through the bucket spool in the right control
valve.
