KaVo Expert Series INTRAsurg 300
KaVo · Model Expert Series INTRAsurg 300
• Very simple operation • Intelligent motor control • Program with 6 steps • Display of actual speed and actual torque • New straight and contra-angle handpieces
Key tips
- ·Biological-indicator verification applies to dental sterilizers exactly the same as hospital CSSD - no exception for smaller units.
- ·"Sounds different" is often the first real report of handpiece bearing wear, not an outright failure - investigate early rather than waiting.
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.
Handpiece turbine / bearing wear
HighSymptoms: Low RPM, chatter, poor cutting performance.
Root cause: Bearing/turbine wear from autoclave cycles.
Motor speed-control fault
MediumSymptoms: Erratic or unresponsive RPM, motor stalls under load.
Root cause: Control board or motor winding fault.
Handpiece cable / connector wear
MediumSymptoms: Intermittent power, cuts out mid-use.
Root cause: Cable flex fatigue at the motor connector.
Foot control failure
LowSymptoms: No/erratic activation.
Root cause: Fluid ingress / worn switch.

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.
- ·Daily handpiece lubrication and autoclave cycle verification
- ·Compressor moisture-trap draining
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Handpiece turbine / bearing wear
- Confirm the presentation - typically low RPM, chatter, poor cutting performance - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: bearing/turbine wear from autoclave cycles.
- 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 handpiece turbine / cartridge 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.
