In order to preserve the adjustment of the bed lowest position when replacing a Hi-lo
actuator, a special tool kit designed for that purpose must be used.
To obtain this kit, contact our Service department (see section 1.2) and order part number
KR0054.
1. Bring the head side-rails down and raise the foot side-rails.
2. Raise Fowler by approximately 50°, so that the loosening of the bolt (
L
) holding the Hi-lo
actuator to its support is not hindered.
3. Raise the Knee Gatch to the high position.
4. Manually lift and fold the foot section back towards the head end of the bed (see figure
4.1 in Appendix B).
5. Place the alignment jigs on the base of the bed as illustrated in figure 4.14A in Appendix
B.
6. Lower the bed until it rests completely on the jigs. If one or both Hi-lo actuators are
defective, use a ratchet and the socket included in the tool kit to lower the bed on the
jigs.
7. Unplug the power cord from the wall receptacle.
8. Disconnect the actuator cable (
J
) connector and cut the cable ties holding it onto the
frame.
9. Remove the Rue ring/washer/nylon washers(2)/clevis pin (
K
) holding the Hi-lo actuator
tube to the Hi-lo lever arms.

Apply grease on the clevis pin and the nylon washers before hooking back the actuator tube
to the Hi-lo lever arms.
10. Loosen the bolt (
L
) holding the Hi-lo actuator to the bracket until the actuator can be
rotated downward and removed from its location.

Apply grease on the bolt, the spring washer and the inner sides of the bracket, including the
pivot pin, when reassembling the actuator.
11. Reverse the above steps to install replacement Hi-lo actuator.
It is of utmost importance
that the Hi-lo replacement actuator be adjusted prior to hooking
up its tube to the Hi-lo lever arms. An improper adjustment of the actuator can damage the
bed mechanisms.
11.1. Proceed as follow to adjust the new Hi-lo actuator:
•
Plug the bed. Make sure that the Hi-lo actuator cable is connected.
•
Hold firmly the actuator tube and run the Hi-lo function up for a few seconds then
run it down until it stops. This will be the Hi-lo actuator lower limit.
•
Turn, if necessary, the tube in either direction to align the tube holes with the Hi-
lo lever arm holes and insert clevis pin.
12. Test Hi-lo function for proper operation before returning bed to service.
