Narrow Hallway

If a QDR 4500A, or QDR 4500SL, unit must be moved through a hallway that is not at least 45"
(114cm) wide, the C-arm can be removed. This allows the unit to fit through a hallway 29"
(74cm) wide (inside dimension). See the instructions for removing the C-arm below.

REMOVE TABLE TOP (IF NECESSARY)

Note: It is not necessary to remove the table top if the doorway(s) the unit must go through is at
least 81" (206cm) high (top to bottom inside dimension). Removing the table top allows
the unit to fit through a doorway 79" (201cm) high.
The table top can be removed before taking the unit off the pallet. Follow the procedure below to
remove the table top:
1. Remove the table pad, and remove the right table rail end cover (2 Phillips screws
located on the right end). This cover slides straight out the end.
2. Remove the two screws (Phillips) that secure the table top in place (located on top of the
table near the rear center), and slide the table to the left far enough to access the Table
X bearing blocks.
3. Referring to Figure 3-7, remove the right side front endcap (3 Phillips screws).
4. Remove the back Phillips screw from the right side cover (of the table X drive
assembly) and slide the cover out from the front.
5. Unplug the cable to the Motor Controller board.
6. Refer to Figure 3-7. Disconnect the stainless steel cable guard (2 screws), and remove
the Table X drive attachment bracket (4 bolts and 2 nuts).
7. Remove the left rail stop (1 counter sunk screw, located next to the left side front
endcap) to allow the table top to be rolled off from the front.
8. Remove the 8 Allen screws (6mm) holding the table X drive bearing blocks.
