Elevating Base - GE Giraffe OmniBed Service Manual

Chapter 5: Repair Procedures

5.9.4 Elevating Base

Refer to "Figure 5-50 Bed Disassembly" and "Figure 5-53 Elevating Base".
1. Run the elevating base to its top travel limit.
2. Remove the mattress, bed, translation deck, tilt platform, and pan.
3. Run the canopy to its lowest position (closed). Use the shipping locks (Figure 5-14) to lock the canopy in the
down position. Switch off and unplug the unit.
4. Remove the chassis cover. (Refer to section 5.9.1.)
5. Disconnect the elevating base electrical connector at J-45 on the relay board, and tie a wire to it so you can
fish it back through during reassembly.
6. Connect the replacement elevating base to the relay board, switch the unit back on and using the foot
pedals fully extend the new base. Switch off and unplug the unit.
7. Using a 4mm hex key remove the 4 screws (at the bottom of the base- 2 in back and 2 in front) that secure
the lower shroud and slide it up past the speaker.
8. Using 3mm hex key remove the 8 screws that secure the upper shroud and remove it.
9. Pull the base wire harness out from the bracket casting.
10. 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.
11. 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.
12. 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)
13. 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.
