6.2.2 Turbine Motor Replacement
If the turbine motor is operated using oil-laden or dirty air, it will fail, and require replacement.
Failure of the motor due to contamination in the spindle air is not covered under the warranty.
The motor may also require replacement after an extended operating life or following a severe
collision. There are no user serviceable parts in the turbine motor. Flexdeburr units with defective
motors should be returned to ATI during the warranty period. Motors are sold as complete, modular
assemblies to simplify and speed user installation. Should the customer wish to replace the motor
after the warranty period, perform the following steps:
