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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Motor / actuator wear
MediumSymptoms: Weak or erratic motion.
Root cause: Gear/motor fatigue.
Range-of-motion limit switch fault
MediumSymptoms: Won't reach set ROM, sudden stop.
Root cause: Limit switch or encoder wear.
Frame / joint pad wear
LowSymptoms: Patient discomfort, loose fit.
Root cause: Foam/pad compression over use.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Motor / actuator wear
- Confirm the presentation - typically weak or erratic motion - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: gear/motor fatigue.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the drive motor / actuator per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
