10-Step Process

1.Schedule a pick up

2.Use customised 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

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
  • 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
