Your Cascade 2671 Duo Cart

OR Cascade 3171 Duo Wall-Mount

Your duo unit includes the Cascade handpiece delivery system and assistant’s instrumentation. The handpiece delivery system is built around A-dec’s proven Century Plus® control block for three handpieces.

Handpiece activation is automatic. When you lift a handpiece from its holder, the handpiece becomes active and will run when you press on the foot control disc (refer to page 5). Return the handpiece to its resting position to deactivate it.

Adjustment keys (see Figure 1) are provided for your use when making adjustments to the recessed controls, including coolant air, coolant water, and handpiece flush. If the adjustment keys are ever misplaced, you can use a 1⁄8" hex key. You may order additional or replacement keys from your authorized A-dec dealer.

Foot Control

The foot control modulates drive air to the active handpiece and provides an air signal that activates the coolant air and coolant water flow. The foot control is operated by light foot pressure applied to any part of the foot control disc.

The foot control is equipped with a wet/dry toggle and can be equipped with an optional chip blower button (see Figure 5).

Master On/Off Toggle

The master on/off toggle

(see Figure 6) turns air, water, and electricity on or off to the system.

CAUTION

The MASTER ON/OFF TOGGLE should be in the

OFF (0) position whenever the unit is not in use.

This will prevent the possibility of water damage should a leak occur while the unit is unattended.

Making sure the unit is off will also prevent the possibility of self-activation and the resulting burn-out of your electrical accessories.

Drive Air Pressure Controls

The drive air pressure controls (see Figure 6 on page 6) are used to adjust the drive air pressure to each handpiece.

Adjust the drive air pressure to meet the handpiece manufacturer’s dynamic drive air pressure specification. Refer to the documentation that came with your handpiece for the dynamic drive air pressure specification.

You will need a 3⁄32" hex key to complete this adjustment.

1.Install a bur in the handpiece.

2.Locate the drive air gauge on the front of the control head (see Figure 4 on page 4).

3.Move the wet/dry toggle on the foot control

(see Figure 5 on page 5) to the OFF position, away from the blue dot.

4.Turn the drive air control clockwise until the valve seats.

5.Fully depress the foot control disc.

6.While running the handpiece, watch the drive air gauge and adjust the handpiece dynamic drive air pressure to meet manufacturer’s specifications.

•Turn the drive air control counterclockwise to increase drive air pressure flow.

•Turn the control clockwise to decrease flow.

NOTE

Do not turn the control counterclockwise beyond the point where the drive air pressure no longer increases. The control adjustment screw may come completely out of the unit.

7. Repeat steps 1 through 6 for EACH handpiece.
