The Tubehead and Articulating Arm are installed as a single unit.
1. Remove the top level packing material from the shipping carton to gain
access to the Articulating Arm and Tubehead Assembly. Do not remove the
cardboard tube enclosing the cable wires but remove the red tag.
2. Remove the Articulating Arm and Tubehead Assembly from the shipping
carton.
Note: Do not lubricate the shaft of the Articulating Arm or the bearings in the
Control Unit.
3. Position the Articulating Arm above the Horizontal Arm.
4. Carefully route the cardboard tube with the arm cable plug through the
opening in the Horizontal Arm.
5. Insert the shaft of the Articulating Arm into the opening in the Horizontal Arm,
as shown in Figure 20.
6. Press down until the shaft is completely seated in the Horizontal Arm.
7. Remove the cardboard tube to free the wires. Discard the cardboard tube.
