CONTENTS

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.

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).

Wet/Dry Toggle. Allows you to shut off the coolant water to the handpiece without moving your hands from the oral cavity. Using your foot, move the toggle away from the blue dot to turn the coolant water OFF. Move the toggle toward the blue dot to turn the coolant water ON.

Chip Blower Button. Sends a jet of air through the handpiece when it is not running.

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.

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.

7. Repeat steps 1 through 6 for EACH handpiece.
