Case CX490D Operator's Manual page 61

C position: BHL control pattern
Left-hand control lever:
1. The boom lowers.
2. The boom raises.
3. The upper structure swings to the left.
4. The upper structure swings to the right.
NOTE: The speed of movement of the boom or the swing
depends on the control lever tilt angle. In the intermediate
position two movements can be obtained simultaneously.
NOTE: when the upper structure swing control is re-
leased, the upper structure may continue to rotate due to
the force of inertia. In this event, make allowance for the
extra movement by releasing the control slightly earlier.
Right-hand control lever:
5. The arm extends.
6. The arm retracts.
7. The bucket retracts (filling).
8. The bucket extends (dumping).
NOTE: The speed of movement of the arm or the bucket
depends on the control lever tilt angle. In the intermediate
position two movements can be obtained simultaneously.
