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
