CONTENTS

Your Cascade Handpiece Delivery System is
built around A-dec’s proven Century Plus
®
control blocks for three handpieces and, in
most instances, A-dec’s Autoclavable Syringe.
Handpiece actuation is automatic. When you lift a
handpiece from its holder, or pull the Continentalstyle whip forward, the handpiece becomes active
and will run when you press on the foot control
disc (refer to page 3). Return the handpiece to its
resting position to deactivate it.
The drive air pressure gauge (see Figure 2) indicates,
in psi and kg/cm2, the drive air pressure to the
active handpiece.

The arm is braked against vertical movement
until you press the arm brake button (see Figure 2
on page 2). You then are able to position the
control head. Releasing the arm brake button
locks the control head in place
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 3).
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 4
on page 4)
are u
sed 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 2 on page 2).
3. Move the wet/dry toggle on the foot control
(see Figure 3 on page 3) 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.
