8. Lift the litter top up and support it about 6” above the lift screws with sawhorses or the equivalent.
9. Under the base, using a 9/16” socket, remove the four nuts (B) holding the lift housing to the base.
10. Lift up and out on the lift housing assembly to remove it from the base. (See pages 83–86 for servicing
procedures for lift housing components.)
CAUTION
After service has been completed on the lift housing, the inner and outer screws must be ”timed”. If this timing
measurement is not equally maintained between the two lift drive screws, the drive screws will not move up
equally, and damage to the bed’s moving parts could result. (Refer to step 10 on page 84 for proper timing
procedure.)
CAUTION
See pages 91 and 92 for proper reattachment procedure for power and sensor coil cords.
11. Reverse the above steps to reinstall the lift housing assembly after service is completed.
NOTE
The procedure for lift housing removal and replacement is the same for both ends of the bed.
