15 Height Actuator - Replacement
This section describes how to replace the height actuator. Reference is made throughout this section
(“Electrical Assembly” on page 22) and (Figure 4 on page 31).
15.1 Removal
To remove the Height Actuator:
15.1.1 Disconnect the bed from the mains power supply. Disconnect the backup battery
(Fig 4, Item 26) refer to Subsection 9.1 but do not remove it from the bed.
15.1.2 Release the cable clips from the height actuators (Fig 4, Item 7) and unplug both height
actuator cables (“Electrical Assembly” on page 22, Item 17 and 18) refer to Subsection 1.2. Pry
off and discard the starlocks (Fig 4, Item 9) securing the clevis pin at both ends of the faulty
actuator.
15.1.3 If changing the foot end actuator, attach the hoist to the foot end of the sub-frame; similarly at
the head end. Raise the frame until the faulty actuator just comes free on its mountings. Use
blocks or stands to support the sub-frame in this position.
15.1.4 Knock out both clevis pins (Fig 4, Item 8) to release the actuator from the sub-frame
(Fig 4, Item 1) and radius arm (Fig 4, Item 2) or (Fig 4, Item 3) and remove it from the bed.
Collect two shakeproof washers (Fig 4, Item 21).
15.2 Installation
To install the Height Actuator:
15.2.1 Position the height actuator (Fig 4, Item 7) on the bed with the actuator body towards the
centre of the bed. Fit a shakeproof washer (Fig 4, Item 21) and clevis pin (Fig 4, Item 8) to
attach the actuator body to the sub-frame fabrication (Fig 4, Item 1). Secure with a new
starlock (Fig 4, Item 9). Make sure the shakeproof washer and starlock fit tightly against the
mounting bracket as shown in Figure 16.
15.2.2 Connect the cable (“Electrical Assembly” on page 22, Item 17 and 18) to the new actuator.
Reconnect the backup battery (Fig 4, Item 26) refer to Subsection 9.2. Support the actuator.
Use the bed height controls to extend the actuator ram and align the hole with the fixing bracket
on the radius arm (Fig 4, Item 2) or (Fig 4, Item 3). Ignore the audible battery warning.
WARNING
Before removing the height actuator ensure that the sub-frame is securely
supported on suitable stands or blocks.
