Proper anatomical therapy, accurate range of motion and ultimate comfort for all patient types Accommodates pediatric, athletic and bariatric patients Lightweight (25 lbs) and portable (28 in.) Constructed with mild steel and a dual ball screw assembly - exclusively Circuitry located in base of unit instead of hand control for fundamental protection Easy to understand hand-held control features a bold LED digital display Patient lock out feature prevents inadvertent changes to settings Compliance meter records treatment time Features safety stop if motion is obstructed Universal left/right design Quick conversion from adult to pediatric - no additional accessories needed Tripod position offers easy storage option and reduces contamination Axis to axis motion, skid pad and bed stabilizing system prevent migration.
Key tips
- ·Most "no output" stim-unit complaints are cable-side - check electrode/lead continuity before assuming a unit fault.
- ·Frame and strap wear on mechanical rehab equipment is a real fall/injury risk - don't defer it as cosmetic.
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.
Motor / actuator / drive will not run or is weak
HighSymptoms: Traction force not applied, CPM carriage will not move or stalls, drive assist weak, motion one direction only.
Root cause: Worn drive motor / leadscrew / actuator, a hand-control fault, or a control-board fault.
Force / range / position inaccuracy
MediumSymptoms: Set traction force or CPM angle not reached, load cell drifts, carriage overshoots or stalls short.
Root cause: Load-cell / position-sensor drift, a potentiometer fault, or a limit-switch fault.
Hand control / patient-control fault
MediumSymptoms: Hand control unresponsive, the patient stop / reverse button does not work.
Root cause: Worn hand control or a damaged cable.
Frame / bearing / cable wear
MediumSymptoms: Rough or noisy travel, play in the carriage, frayed traction cord or rope.
Root cause: Worn bearings / slides or a frayed cable / cord.
Power / battery fault
LowSymptoms: Will not power on, short battery run time.
Root cause: Power supply / fuse or an aged battery.

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.
- ·Frame and strap wear inspection
- ·Electrode lead continuity check
- ·Annual electrical safety test
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: Carriage will not move / stalls / moves one direction only
- Confirm mains / battery and that the patient stop / e-stop is released.
- Try the hand control and, if fitted, the unit buttons to isolate the control.
- Listen for the drive motor and check the leadscrew is not jammed or dry.
- Check the hand-control cable for damage.
- Replace the hand control, drive motor or control board as isolated.
Symptom: Set flexion / extension angle not reached / carriage overshoots or stalls short
- Run the calibration / homing routine.
- Check the position sensor / potentiometer and the limit switches.
- Verify the achieved angles with a goniometer.
- Replace the position sensor if it drifts.
- Re-verify the ROM range and the patient stop.
Symptom: Rough / noisy travel / play in the carriage
- Inspect the carriage bearings / slides for wear.
- Check the leadscrew and its nut for backlash.
- Re-lubricate per the manual.
- Replace worn bearings / slides.
- Confirm smooth quiet travel through the full range.
