Cascade 3072 Handpiece Control System
Your Cascade Handpiece Control System
Your Cascade 3072 Handpiece Control System
is built around A-dec’s Century Plus
system for three handpieces. The system also
includes the A-dec autoclavable syringe.
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).
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.

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 burnout of your electrical accessories.

Cascade 3072 Handpiece Control System
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 4).

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.

Handpiece Tubing Flush
The handpiece tubing flush system
flushes more water through the tubings
in less time than is normally possible
when operating the foot control only.
The handpieces should not be connected
when flushing the tubings.
How Often Should the Handpiece Tubings be Flushed?
After Each Patient:
Flush the tubings for about 20-30 seconds.
At the Beginning of Each Day:
Flush the tubings for 2-3 minutes.
Flushing the Handpiece Tubings
Gather up all the handpiece tubings that use
coolant water and hold them over a sink, cuspidor
bowl or basin. Be sure you hold the tubings so that
the water will be directed away from you and into
the receptacle (see Figure 5).
Insert an adjustment key or 1⁄8" hex key into the
handpiece tubing flush control on the side of the
control head. Push in and hold the key for the
appropriate time required, either for flushing
between patients or flushing at the beginning of
each day, depending on the situation. Remove the
key and replace the tubings in their holders.

Handpiece Holder Tension Adjustment & Positioning
The holder tension was set at the factory. However; if
a holder is difficult to reposition or repositions too
easily, the holder tension can be adjusted.
To adjust the holder tension:
• Loosening or tightening the tension adjustment
screw shown in Figures 6A and 6B.
To reposition a holder:
• Rotate the holder to the desired angle.

Handpiece Dry Block Conversion
Your Cascade handpiece control system has one to
four handpiece control blocks with coolant water to
the handpiece. In some cases a control block without
coolant water, a dry block, is required. If you require
a dry block (offering no water to the handpiece) on
your handpiece control system, a dry block
conversion kit has been included with your system.
Installing the Dry Block Conversion Kit
1.
Move the master on/off toggle to the OFF
position. Bleed the system water by operating
the syringe and flushing the handpiece tubings.
2. Locate the handpiece control block position
that will be the dry block. Access the control
blocks underneath the control head.
3.
Use a 3/32" hex key to remove the large red
cartridge from the control block. Install the large
black cartridge from the dry block conversion kit
into the control block (see Figure 7).
4.
Use a 3/32" hex key to remove the small blue
cartridge from the same control block. Install the
small black cartridge from the dry block
conversion kit into the control block (see Figure 7).
5. Turn your handpiece control system on, then
check the function of the dry block handpiece
conversion. A small amount of residual water
may be discharged from the handpiece tubing
but should dry after a few seconds.

Oil Collector
The oil collector on your unit needs to be changed
once a week for normal usage. Change more often
for heavier use.
1. Remove the oil collector jar from the unit and
discard the old gauze (see Figure 8).
2. Fold in quarters a new two inch square gauze
pad and place against the spring inside the jar.
3. Screw the oil collector jar onto the unit. Do not
over tighten.

Flexible Arm
Cascade 3072 Handpiece Control Systems are
available on A-dec’s flexible arm system. The
flexible arm allows vertical and horizontal
positioning of the control head to suit your
practice.
Counterbalance Spring Adjustment
The flexible arm contains a spring that
counterbalances the weight of the control
head. The arm also contains a friction
mechanism to stabilize the arm at the
upper and lower extremes of its vertical arc.
If the arm tends to rise or drop when the arm
brake is released, the counterbalance spring
needs adjustment.
1. Remove the flexible vinyl cover from the
underside of the arm (see Figure 10). Gently
pull the tubing and wiring in the arm
slightly aside.

PULL DOWN ON ONE END

2. Raise the control head end of the flex arm until
the friction adjustment socket head screw is
accessible through the access hole in the arm (see
Figure 11). Using a 5⁄32" hex key loosen, but do
not remove, the friction adjustment.

3. If the arm tends to drop, use a flat-blade
screwdriver to turn the spring tension
adjustment nut clockwise (as viewed from the
control end of the arm, see Figure 12). If the
arm tends to rise, turn the adjustment nut
counterclockwise. Lift the control end of the
flex arm as high as possible while turning the
adjustment nut, this relieves the spring tension
allowing the nut to turn more easily.
4. While adjusting the spring tension, frequently
move the arm through its vertical arc to see if it
is adjusted properly.

5. When you are satisfied with the spring tension
adjustment, move the arm alternately full up
and then full down positions releasing the
control head at each position. If the arm drops
or rises when you let go of it in either position,
tighten the friction adjustment. Be careful not
to overtighten the adjustment as you may
damage the friction mechanism.
6. Reinstall the flex vinyl cover (see Figure 13).
The cover is easily snapped back into place.
Start by inserting one end of the cover into
the arm and press it into place along the
bottom of the arm.
