Procedure:
1. Using a #2 Phillips screwdriver or a T27 Torx, remove the ten screws holding the foot and midsection litter
access covers to the litter and remove the covers.
2. Using a 3/8” socket wrench or a T27 Torx, remove the two bolts holding the ground straps to the motion
interrupt pan.
3. Run the head section down electrically until flat (0) or use the CPR release handle to fully lower the head.
4. Lightly tap the Fowler down button until the bolt and bushing (E) are centered in the slot.
5. Unplug the power cord from the wall socket.
6. Using a 5/16” nut driver, loosen the two screws (A) on the cam (B).
7. Slide the cam toward the head of the bed just until the microswitch is activated (the switch will make a
clicking noise).
NOTE
Check that the cam ”bump” is on the ”head” side of the switch actuator.
8. Tighten the two screws (A).
CAUTION
Be sure the head section stops when it is fully up and the ball nut bracket (C) is approximately 3/4” from panel
(D). If not, damage to the unit could result.
9. Ensure the head section will lower to flat (0) before returning the bed to service. Verify the head section
lowers onto the rubber rests and the motor stops running.
22. Reinstall the litter access panels removed in step 1.
