Replacement Procedure:
1. Raise the litter up to full height and unplug the bed power cord from the wall socket. If the bed will not
raise electrically or manually, pull up on the litter top until it is fully raised.
2. Support both ends of the litter top with sawhorses or the equivalent.
3. Using a #2 Phillips screwdriver, remove the three Phillips screws holding the base hood to the base frame.
4. If the bed is equipped with the 110V outlet option, remove the slotted screw holding the outlet cover. If
the bed does not have the 110V outlet option, remove the two slotted screws holding the cover plate.
5. Use bungee cords or the equivalent to secure the hood up and out of the way.
6. Using a 3/16” Allen wrench, remove the socket head cap screw from the litter support tube at the end of
the bed needing service.
7. While depressing the appropriate release pedal, separate the jack shaft from the support tube and depress
the jack shaft to the full down position.
8. Using a 1/4” Allen wrench and a 1/2” socket wrench, remove the nut and bolt holding the pump piston to
the pump bar.
NOTE
If you are working on the foot end of the bed, be careful when removing the bolt. The spring must be com-
pressed and the pump bar bracket must be pushed down and out of the way so the bolt and the spring can
be removed.
9. Using wire cutters, remove all wire ties holding the pressure and return lines to the frame.
10. Using a 3/8” socket wrench, remove the three bolts holding the pump motor cover to the base and remove
the cover.
11. Using a 9/16” wrench for the pressure line and a 11/16” wrench for the return line, remove the lines for
the jack being replaced at the pump.
12. Using a 1/2” wrench and a 1/2” socket wrench, remove the two nuts and bolts holding the jack support
bracket on the jack and remove the bracket.
13. Using a 1/2” wrench and a 1/2” socket wrench, remove the four nuts and bolts holding the jack assembly
to the frame. Using a floor jack, lift the end of the bed you are servicing and remove the jack from under-
neath the base frame.
14. Reverse the above procedure to install the new jack and reinstall the base hood.
