Hayes 10-step process for servicing your high-speed handpiece
1. Schedule a pick up
2. Use customized software to determine if handpiece is covered under warranty
3. Diagnose the problem
- Test water spray, chuck strength and turbine
- Test for air leaks
- Check fibre optics
- Look for any cracks or dents
- Ream head if applicable
4. Disassemble the handpiece, removing all moving parts and components

5. Clean the handpiece externally and internally
- Remove all debris, including rust, from the drive air tube, exhaust tube and chip air and chip water tubes
- Clean internal and external head and remove dents
- Clean and polish external shell and fibre optic ports

6. Check impeller and spindle for wear and nicks
7. Test for concentricity
- Perform concentricity tests using proprietary concentricity gauge
- The proprietary concentricity gauge allows Hayes technicians to prevent bur deflection from exceeding .0011 inches, which reduces stress and potential damage to the handpiece turbine

8. Overhaul handpiece and reassemble
- If the turbine is rebuildable, rebuild with premium parts and bearings to OEM standards
- If the turbine failed chuck strength and/or concentricity tests, install a replacement turbine (your choice of OEM or aftermarket turbine)
- Inspect and repair water spray to ensure proper atomisation
- Check water and chip air tube
- Replace O-rings, fibre optics and end gasket if applicable
- Rethread if applicable


9. Test torque, RPM and noise
10. Return handpiece and review maintenance procedures with your staff if needed
- Discuss maintenance for handpieces and attachments
- Review different types of lubricants and cleaners
- Check air pressure for each handpiece
- Review autoclaving and related procedures
