Make sure that the support and the molded nut holes are aligned before screwing in the bolts. If
resistance is felt, stop immediately; the holes then are not aligned.
9. Remove the defective actuator.
10. Reverse the above steps to install the new actuator. Take note of the following caution
before hooking up the molded nut support to the Hi-Lo lever arms.
The course of the new actuator must be adjusted prior to hooking it to the Hi-Lo lever. An
improper adjustment can damage the Hi-Lo mechanism.
10. To adjust the new actuator, proceed as follows:
A. Once the new actuator cable connected, plug the bed power cord and press the bed
down control until the actuator stops. This will be the lower limit of the actuator course.
B. Attach the molded nut support to the Hi-Lo lever arms (see note following step 8).
C. The alignment jigs still in position, raise and lower completely the bed to ensure that
the lower limit is properly adjusted.
