Making Handpiece Control Adjustments |

Location of Control Adjustments
The control adjustments for the handpiece flush control, drive air pressure, coolant air flow, and coolant water flow are located on the side of the control head.
Operators Adjustments
Use the adjustment key to make adjustments, with the exception of the drive air pressure. The adjustment key will not fit the drive air control ports. This was done to prevent unintentional changes to drive air settings. To adjust the drive air, use a 3/32" hex key.
