17 Thigh Actuator - Replacement
This section describes how to replace the thigh actuator. Reference is made throughout this section to
“Electrical Assembly” on page 22 and Figure 3 on page 29.
17.1 Removal
To remove the Thigh Actuator:
17.1.1 Raise the bed to maximum height to allow easy access to the underside of the mattress
platform. Release the cable clip from the thigh actuator (Fig 3, Item 8) and unplug the actuator
cable (“Electrical Assembly” on page 22, Item 15) refer to Subsection 1.2.
17.1.2 Pry off and discard the starlocks (Fig 3, Item 10) from both ends of the thigh actuator. Attach
the hoist to the foot end of the mattress platform and slowly raise the bed until the thigh actuator
just becomes free on its mountings.
17.1.3 Knock out two clevis pins (Fig 3, Item 6) to release the actuator from the thigh section
(Fig 3, Item 12) and sub-frame assembly (Fig 3, Item 11). Collect two shakeproof washers
(Fig 3, Item 9).
17.2 Installation
To install the Thigh Actuator:
17.2.1 Position the thigh actuator (Fig 3, Item 8) on the bed with the ram pointing towards the foot
end. Attach the actuator body to the sub-frame assembly (Fig 3, Item 11) with the clevis pin
(Fig 3, Item 6) and shakeproof washer (Fig 3, Item 9). Secure the assembly with a new
starlock (Fig 3, Item 10). Make sure the shakeproof washer and starlock fit tightly against the
mounting bracket – see Figure 16.
17.2.2 Position the thigh section (Fig 3, Item 12) to align the mounting lug with the hole in the thigh
actuator ram. Attach the actuator ram to the thigh section using the clevis pin (Fig 3, Item 6)
and shakeproof washer (Fig 3, Item 9) and secure with a new starlock (Fig 3, Item 10). Make
sure the shakeproof washer and starlock fit tightly against the mounting bracket – see
Figure 16.
17.2.3 Connect the thigh actuator cable (“Electrical Assembly” on page 22, Item 15). Make sure the
connector is fully seated in the socket and refit the cable clip, refer to Subsection 1.2.
WARNING
Ensure that the foot end of the mattress platform is securely supported before
removing the thigh actuator.
