Page 40: Transporting The Articulator
Danger The Model 721XF Articulator uses hydraulics to lower/lift the decks, and fold up the two outside decks (721XF only), allowing easy transportation. This feature has many other benefits, including remote operation, access across narrow bridges, through gates, or doorways, and reduction of required storage space. - Page 41 8. Upon arriving at the work area, activate the hydraulics, lowering the Articulator. Lower the decks until the hydraulic cylinders are fully extended on the wing decks (721XF) and retracted on the main frame. The cylinders on the outside two decks should be com- pletely extended and centered in the slots on the front decks (decks 1 and 3) to allow for proper deck flotation (721XF only).
