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.
Treadmill will not start / no communication with the stress system
HighSymptoms: Belt will not run, no display, ECG / stress system cannot control it.
Root cause: Facility / treadmill breaker, a blown fuse, a cut power cord, the control cable to the stress system, or a drive-controller fault.
Speed or grade error / inaccuracy
MediumSymptoms: Belt speed or incline does not match the protocol, error code, grade drifts.
Root cause: Grade motor / potentiometer needs calibration, a limit-switch fault, or a drive speed-feedback fault.
Walking belt / deck wear
MediumSymptoms: Belt slips, drifts off-centre, rough or noisy running.
Root cause: Worn or stretched belt, worn deck, or drive-belt tension loss.
Emergency stop / handrail fault
HighSymptoms: E-stop does not stop the belt, loose handrail.
Root cause: Failed e-stop switch/wiring or loosened handrail fasteners.

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: Will not start / no comms
- De-energise and unplug before removing covers.
- Check the breakers and any fuse.
- Inspect the power cord.
- Check the control cable between the treadmill and the ECG / stress system.
- If power is present and cabling is good, suspect the drive controller.
Symptom: Speed or grade inaccurate
- Verify belt speed with a tachometer against the protocol.
- Calibrate the grade potentiometer and check the limit switches.
- Inspect the drive speed-feedback path.
- Re-verify speed and grade.
- Centre and tension the belt and confirm the e-stop stops the belt.
