Troubleshooting after Turbine Installation

1. The turbine does not spin freely after installation

This is usually caused by improper installation. Most likely, the turbine has rolled, moved or damaged the front o-ring during installation. Sometimes, this occurs when old components are left in the handpiece head during turbine removal. In cases where springs and/or shims are placed on front of the turbine during installation, they could settle incorrectly and cause resistance. In all cases, re-install the turbine, do not run the handpiece until corrected.

2. The turbine sounds loud or runs rough after installation

This is usually caused by o-ring misplacement or damage, or improper back cap placement. In these cases, re-install the turbine. It is very important to replace o-rings with new ones, worn o-rings could cause this problem. Also, debris left in the handpiece head or head damage could cause this problem. Try removing the turbine and cleaning the handpiece as described in the installation instructions. If the handpiece head has damage or dents, the handpiece must be repaired before using. Damaged handpiece heads will damage turbines.

3. The back cap gets hot during use

In these cases, stop using the handpiece. Re-install the turbine to ensure that it is seated properly. If the turbine is not assembled in the proper position on the spindle, or has been moved, the back of the spindle could rub against the back cap. Continued use will damage the turbine and could cause discomfort to patients. Also, your push button back cap could be stuck in the down position, which would then rub against the spindle. In this case, remove the back cap and clean. If the back cap continues to stick, it must be replaced.

4. I'm having turbine failures

Improper maintenance procedures is the number one reason for turbine failures. Do not over temperature your handpieces during sterilization cycles (not to exceed 275 f). Handpieces should be flushed prior to sterilization to remove debris. Handpieces should be lubricated after sterilization (maintenance free turbines should be lubricated from time to time to lubricate components such as o-rings and spindle assemblies).

5. My handpieces are running slow

Try removing the turbine and cleaning the inside of the handpiece head, debris could cause slow performance. Check to ensure that your air pressure is properly gauged at the chair unit. Try replacing the gasket at the back end of the handpiece, a worn gasket will cause air to escape out the back of the handpiece.

6. Warranty

If your turbine fails within the warranty period due to defects in materials or workmanship you may be entitled to a replacement unit.
