3 - CONTROLS AND INSTRUMENTS
D position: ISO control pattern
Left-hand control lever:
1. The arm extends.
2. The arm retracts.
3. The upper structure swings to the left.
4. The upper structure swings to the right.
NOTE: The speed of movement of the arm 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.
