Your Cascade Traditional-style Handpiece
Control System is an arm-mounted control, built
around A-dec’s Century Plus

®

control system for
three handpieces. The control system can
accommodate up to four handpieces. The control
system includes A-dec’s autoclavable syringe; and
may also be equipped with an optional built-in
ultrasonic scaler, low voltage water heater/heated
syringe tubing, tooth dryer, electric handpiece,
curing light, and intra-oral light source.

Handpiece activation is automatic. When you
lift a handpiece from its holder, the handpiece
becomes active; allowing it to run when you
press on the foot control disc.

Five autoclavable adjustment keys (see
Figure 1) are provided for your use when making
adjustments to the recessed controls. If the
adjustment keys are ever lost or misplaced, you
can use a 1⁄8-inch hex key instead.

Owner's Guide, (A-dec Publication No. 85.2627.00).

The foot control modulates drive air to the
active handpiece, and provides an air signal
that turns on 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, optionally, a chip blower button
(see Figure 6).

If the unit is equipped with the optional Cascade
Master Series touch pad, the standard Cascade
Master foot control will not have a wet/dry
toggle. The coolant water (wet/dry) on/off
control is located on the Master touch pad for
better accessibility.

Cascade Traditional Handpiece Control System

Your Cascade handpiece control system is
equipped with A-dec’s handpiece tubing flush
system. The 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 7).

Insert an adjustment key or 1⁄8-inch 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. Be
careful to replace each in the proper holder.

Cascade Traditional Handpiece Control System

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

• Move the master on/off toggle to the OFF position.
Bleed the system water by operating the syringe
and flushing the handpiece tubings.

• Locate the handpiece control block position that
will be the dry block. Access the control blocks
underneath the control head.

• Use a 3/32-inch 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 8).

• Use a 3/32-inch 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 8).

• 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 Dry Block Conversion

handpiece tubing but should dry after a few seconds.

The oil collector on your unit needs to be
changed once a week for normal usage. Change
more often for heavier use.

• Remove the oil collector jar from the unit and

discard the old gauze (refer to Figure 9).

• Fold in quarters a new two-inch square

gauze pad and place against the spring inside
the jar.

• Screw the oil collector jar onto the unit. Do

not overtighten.

The syringe included with your Cascade
Handpiece Control System is A-dec’s Autoclavable
Syringe, featuring a three-way air and water
system and a patented quick-disconnect
autoclavable tip system.

The operation, care, and maintenance of the

syringe are discussed in detail in your

Autoclavable Syringe Owner’s Guide (A-dec
Publication No. 85.0680.00).

For maximum flexibility in tray positioning,
the optional tray holder can be rotated a full
360°, and the tray arm can be pivoted to either
side of center (see Figure 10).The optional tray
holder should be adjusted so that it rotates
easily, yet maintains its position while
instruments are removed and replaced.

Tray Holder (optional)

Figure 10. Tray Holder

To adjust the tray holder or tray arm, insert a
9⁄64-inch hex key through the appropriate
mounting bracket (see Figure 11). The hex key
should protrude from the opposite side of the
mounting bracket. If it does not, rotate the
holder or arm until the key slides through the
mounting block. While holding the bracket
stationary, turn the holder or arm clockwise to
increase the tension or counterclockwise to
loosen the tension.

16

Cascade Traditional Handpiece Control System

Handpiece Drive Air Pressure Adjustment

A-dec’s flexible arm system is designed for side
delivery and over-the-patient delivery of the
handpiece control. The arm allows vertical and
horizontal positioning of the control head to
suit your practice.

The arm is braked against vertical movement
until you release the arm brake (refer to page 6).
If the arm tends to rise or drop when the brake is
released, refer to the adjustment instructions below.

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 12). Gently
pull the tubing and wiring in the arm
slightly aside.

2. Raise the end of the flex arm until the
friction adjustment socket head screw is
accessible through the access hole in the
arm (see Figure 13).

Using a 5⁄32-inch hex key, loosen the
friction adjustment screw.

3. If the arm tends to drop, use a flat-blade
screwdriver to turn the spring tension
adjustment nut clockwise (as viewed from
underneath the flex arm) (see Figure 14 on
page 19). If the arm tends to rise, turn the
adjustment nut counterclockwise.

While adjusting the spring tension, frequently
move the arm through its vertical arc to see if
it is adjusted properly.
