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.
