6. Adjust the water coolant flow to the customer’s
preference (normally 1-2 drops per second).
○ Turn the adjustment key to the right to decrease
flow.
○ Turn the adjustment key to the left to increase
flow.
Handpieces—Air Coolant Flow
Use the adjustment key or a hex key to adjust the air
coolant flow to all handpieces.
1. Lift the handpiece from the holder.
2. Locate the air coolant control.
3. Use the Deluxe Touchpad to verify that the air
coolant is on.
4. Insert an adjustment key or hex key into the air
coolant flow control.
5. Press the foot control to activate the handpiece.
6. Adjust the air coolant flow to fit the customer’s needs.
○ Turn the control to the right to decrease flow.
○ Turn the control to the left to increase flow.
Handpieces—Drive Air Pressure
The drive air pressure controls adjust the pressure for
each handpiece. The digital drive air pressure gauge is
located inside the control head. The gauge indicates, in
psi, the drive air pressure as it leaves the control block to
the active handpiece.
To adjust the drive air pressure:
1. If you have a Deluxe Touchpad, ensure the water
coolant is not selected.
2. Locate the drive air pressure gauge and controls
inside the control head.
3. Press the foot control.
4. With the handpiece running, watch the gauge and
adjust the handpiece drive air pressure to meet
manufacturer’s specifications.
○ Turn the control to the right to decrease flow.
○ Turn the control to the left to increase flow.
NOTE
Typically, one of the handpiece
positions is air only. A-dec customizes
handpiece configuration at the time of the
order.
NOTE
Adjusting the air coolant for one
handpiece sets it for all of the positions.
CAUTION
Do not turn the drive air or air
coolant adjustment keys too far. The stem
may come completely out.
NOTE
Use a handpiece pressure gauge
attached to the handpiece tubing for exact drive
air measurement. One bar equals 14.5 psi.
NOTE
Refer to your handpiece documentation
for the drive air pressure specification.
