Actuator Replacement; Bed Schematic - Medline ALTERRA 1385 Operation And Maintenance Manual

ACTUATOR REPLACEMENT

HEAD AND FOOT ACTUATORS
1. Unplug the bed from AC power.
2. Unplug the actuator cable.
3. Remove the clevis pin, cotter pin and spacers from both the motor and piston sides of the
actuator.
Attention: Note the location of all bushings, washers, cable ties, wire routing and hardware for
proper reassembly.
4. Install the new actuator at the motor end first then piston end, using the original clevis pin,
cotter pin and any spacers that were removed in Step 3. Installing the motor end first will
reduce possible damage to spindle and piston mechanism of the actuator.
5. Plug in the actuator cable.
6. Reconnect AC power.
7. Test the bed by raising and lowering the head and foot sections
HIGH-LOW ACTUATORS
CAUTION
• Remove ALL accessories mounted to the bed (assist rails, assist bars and head and
footboards). Failure to do so could result in the bed being unstable causing injury.
• The bed must be turned on its side before replacing actuators. A minimum of two people
are required to turn bed on its side.
• Fully elevate the bed deck and head section before turning the bed on its side to create a
more stable work platform.
1. Remove all accessories mounted to the bed (assist rails, assist bars and head and
footboards).
2. Elevate the bed to its highest position and raise the head and foot sections.
3. Unplug the bed from AC power.
4. With at least TWO people, carefully turn the bed on its side.
5. Remove the clevis pin, cotter pin and spacers from both the motor and piston sides of the
actuator.
Attention: Note the location of all bushings, washers, cable ties, wire routing and hardware for
proper reassembly.
8. Install the new actuator at the motor end first then piston end, using the original clevis pin,
cotter pin and any spacers that were removed in Step 5. Installing the motor end first will
reduce possible damage to spindle and piston mechanism of the actuator.
6. Plug in the actuator cable.
7. With at least TWO people, carefully return the bed to the upright position.
8. Reconnect AC power.

9. Re synchronize the self leveling hi low motors by lowering the bed to its lowest position
and holding the elevation down button on the hand pendant an additional 5 seconds after
the bed has reached its lowest elevation
10. Test the bed by raising and lowering elevation.
NOTE: When replacing head and foot actuators, special care needs t be taken to secure all
wiring with cable ties as necessary to reduce strain from the actuator cables. Ensure that
cable do not get caught on any moving parts.
