Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
A powered function will not move
HighSymptoms: Base, back or a positioning function does not respond to the foot control or touchpad.
Root cause: Foot control / touchpad fault, a hydraulic pump / valve, an actuator, or a control-board fault.
Chair drifts down / will not hold height
MediumSymptoms: Base slowly lowers under load after positioning.
Root cause: Internal leak in the hydraulic system or a failing check valve.
Backrest / headrest will not lock
MediumSymptoms: Tilting back or the headrest slips under load.
Root cause: Worn lock or friction hardware.
Noisy hydraulic pump
LowSymptoms: Loud pump on lift, slow rise.
Root cause: Worn pump or low hydraulic fluid.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: A function will not move
- Use the troubleshooting section of the Boyd service manual for that symptom.
- Test the function from both the foot control and the touchpad to isolate the input.
- Check the hydraulic valve and actuator for that motion.
- Substitute a known-good foot control.
- Replace the isolated valve, actuator or board and re-run an operational test.
Symptom: Chair drifts down
- Note how fast it settles and under what load.
- Check the hydraulic fluid level.
- Inspect the hydraulic system and check valve for internal leakage.
- Rebuild or replace the leaking component.
- Confirm the chair holds height under load.
