Complete the schematic below to provide for the following:
1. Cylinders extend and retract together. The cylinders extend when the valve lever is pulled ouat and
retract when the lever is pushed in.
2. Provide independently adjustable meter-in flow control for extend.
The flow control used to extend Cyl #1 should be labeled "FC1".
The flow control used to extend Cyl #2 should be labeled "FC2".
3. Provide independently adjustable meter-out flow control for extend. retract
The flow control used to retract Cyl #1 should be labeled "FC3".
The flow control used to retract Cyl #2 should be labeled "FC4".
