Completely raise the bed and apply the brakes. Completely raise the Knee Gatch section and flatten the Fowler 1.
section.
Unplug the bed power cord from the wall outlet. 2.
Raise the siderails. 3.
Manually lift and fold the foot section back toward the head end of the bed. Attach it securely to the bed using a 4.
bungee cord.
Using needle nose pliers, remove the rue ring cotter, washers and clevis pin (A) linking the head actuator tube to 5.
the section lever arms.
Remove the foot board. 6.
Using the No. 2 Phillips screwdriver, remove the 10 screws (A, Figure 4.2 A, 7. pg. 32) holding the cover and the two
I.V. pole holders to the foot casing.
Lift up and remove the cover, taking care first to disconnect, from the control board, the control panel cable 8.
(B, Figure 4.2 A, pg. 32) and, if applicable, the foot casing connector cable ((optional), C, Figure 4.2 A, pg. 32).
Properly ground yourself (see 9. pg. 19).
Using cutting pliers, cut the cable tie holding the head actuator cable to the other cables. 10.

casing.
Using the 5/16” socket, remove the two screws (B) holding the retaining plate to the actuator support.12.
Remove the two pivot pins (C) holding the actuator to the support. To facilitate the removal of the pins, insert a small 13.

Move the actuator toward the centre of the bed to remove it from its location. 14.
Reverse the above steps to install the replacement actuator. Take note of the following caution before hooking 15.
up the actuator tube to the head section lever arms.
CAUTION
It is of utmost importance that the course of the replacement head actuator be adjusted before hooking up its tube to
the head section lever arms. An improper adjustment can damage the head section structure.
To adjust the course of the replacement head actuator, proceed as follows: 16.
Make sure that the actuator cable is connected to the control board, and then connect the bed power cord. A.
Grab the replacement actuator tube and position its holes horizontally. While firmly holding the tube with one B.
hand to prevent it from rotating, press the Fowler up control for a few seconds using the other hand, then press
the down control until the actuator stops. This will be the lower limit of the Fowler actuator course.
Gently turn the tube in either direction to align the tube holes with those of the head section lever arms. Then, C.
still holding firmly the tube, raise again the Fowler a few inches, and lower it completely.
Check the alignment of the holes. If the tube holes are not aligned any more with those of the lever arms, repeat D.
steps B and C until they are. Once the holes are aligned, install the washers and the clevis pin. Slightly raise
the head section manually to ease the insertion of the clevis pin.
Before installing the rue ring cotter to finalize the head actuator replacement, raise and lower completely the E.
Fowler. Check that the actuator stops working as soon as the head section reaches the frame.
