Chapter 5: Repair Procedures
6. This step depends on the type of shroud assembly:
• If the shroud assembly is in two pieces: Using a 4 mm hex key, remove the four screws (at the bottom of
the base - two in back and two in front) that secure the lower shroud and slide it up past the speaker.
• If the shroud assembly is in three pieces:
a. Use a 2.5 mm hex wrench to remove four M4 flat washers, four M4 split lock washers, and four
M4x10 button head socket cap screws, that attach the back cover shroud to the lower shroud.
b. Use a 4 mm hex wrench to remove two M6 flat washers , two M6 split lock washers, and two M6x12
button head screws, that attach the back cover shroud to the base plate.
c. Use a 4 mm hex wrench to remove two M6 flat washers, two M6 split lock washers, and two M6x12
button head screws, that attach the lower shroud to the base plate.
7. Using 3mm hex key remove the screws that secure the upper shroud. (For units with two-piece shroud
assembly, remove eight screws. For units with three-piece shroud assembly, remove four screws.) Remove
the upper shroud.
8. Pull the base wire harness out from the bracket casting.
9. Lock the back casters and lay the unit down on its back (controller on the floor). Place blocks under the
uprights so the back casters are off the floor.
10. Using a 4mm hex key, remove the four socket head screws in the bottom of the elevating base that secure
the lower mounting plate to the base, and remove the mounting plate/leg assembly.
11. Using a 13mm socket, remove the 4 nuts that secure the elevating base to the casting and remove the
base.
NOTE: Should the elevating base fail in the completely retracted position, the outer column will prevent
access to the 4 base mounting nuts. To remove the outer base, you must first remove the lower mounting
plate and slide the outer column out. This requires a T-30 TORX key (service tool number 6600-1204-400).
12. To replace the elevating base, reverse the assembly steps above. Check that the casters are still locked
before lifting the unit back into its upright position. If you are returning the old elevating base in its original
packaging, attach it to the relay board and run it down to its fully retracted position. Release the shipping
locks.
NOTE: With the unit on its back, be sure the base power cable is pointing up before you attach the base.
