D. Check the alignment of the holes. If they are not aligned any more, repeat steps
B
and
C
until they are. Once the holes are aligned, install the washers and the clevis pin.
Slightly raise the thigh section manually to ease the insertion of the clevis pin.
E. Before installing the rue ring cotter to finalize the actuator replacement, raise and lower
completely the Knee Gatch. Check that the actuator stops working as soon as the thigh
section reaches the frame.

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. The kit includes alignment jigs. To
obtain the kit, contact our Technical Service department (see section 1.2) and order part
number KR0113.
Required Tools:
Tool Kit (KR0113)
Side Cutters
5/16" Socket Wrench
Small Slotted Head Screwdriver
1/2" Wrench

Unless otherwise indicated, refer to figure 4.3B on page 27 for the illustration of this procedure
reference points.
1. Position the mattress support sections depending on the location of the Hi-Lo actuator to
replace:
At the foot of the bed
: fully raise the thigh section, and lift and fold back the foot section
toward the head end of the bed.
At the head of the bed
: fully raise the Fowler.
2. Position the alignment jigs on the floor right under the
Hi-Lo levers and lower the bed until the levers come
to rest on the jigs (see opposite illustration). Use a
3/8" socket wrench with the 1/2" socket provided in
the kit to lower a defective Hi-Lo actuator until the
lever rests on the jig.
3. Unplug the bed power cord from the wall outlet.
4. Disconnect the actuator cable and clip, using side
cutters, the cable ties holding it to the frame.
5. Remove from the capacitor the two wires (J)
connected to it and remove, using a Phillips
screwdriver, the screw (K) holding in place the capacitor. Dispose of the capacitor.
•
The capacitor of the head Hi-Lo actuator is located in the head casing. To access it,
remove the six screws (A, fig. 4.3D, page 33) holding the cover to the head casing
•
The capacitor of the foot Hi-Lo actuator is located in the foot casing. To access it,
remove the six screws (A, Fig. 4.3C, page 32) holding the cover to the foot casing.
6. Using a 5/16" socket wrench, remove the two screws (M) holding the retaining plate to the
actuator support.
7. Remove the two pivot pins (N) holding the actuator to the support. To facilitate the removal
of the pins, insert a small slotted head screwdriver into the opening at the end of the
actuator and push out the pins.
8. Using a 1/2" wrench, remove the two bolts/washers/shoulder spacers (O) holding the
molded nut support to the Hi-Lo lever. Remove the molded nut support and keep it for the
replacement Hi-Lo actuator that will have its own molded nut.
