2. Adjust mattress support depending on the Hi-lo lever to be replaced:
Hi-lo lever located at the head end of the bed
Raise Fowler to maximum.
Hi-lo lever located at the foot end of the bed
Lower the head safety side-rails and raise the foot side-rails. Raise the Knee Gatch to
maximum. Manually lift and fold the foot section back towards the head end of the bed (see

3. Place two jack stands, adjusted to the height of 20", under the frame, at the head end or foot
end of the bed depending on the Hi-lo lever to be replaced (see fig. 4.21A in Appendix B).
