Page 42: Transporting The Articulator
Danger The Model 721/521XR Articulator uses hydraulics to lower the rear wheels, lift the decks, and fold up the two outside decks(721XR 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. Complete the Ini- tial Set-Up section of this manual BEFORE attempting to operate the Articulator. - Page 43 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 (721XR) 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(721XR only).
