Table Care
Cleaning your Table
Hill table upholstery may be cleaned with Hill Laboratories’ Vinyl and Leather
Cleaner or any household dishwashing liquid mixed with water. Hill also offers
Protex™ Disinfectant Spray and wipes to protect against pathogens, such as
MRSA, HIV, Staph and the H1N1 Swine Flu Virus. Many stubborn stains can be
removed by applying 91% rubbing alcohol (isopropyl alcohol) to the stain and
wiping with a dry, soft, lint-free cotton cloth, towel or soft bristle brush.
Be sure to rinse thoroughly with water.
Caution: Some solvents are highly flammable; do not use near open flame or intense heat. Wear rubber gloves during all cleaning activities. When cleaning other parts of your table (besides upholstery) use only nonabrasive household detergents and water.
Caution and Symbol Explanation
Caution: Children should never be left alone in a room with the table but
should always be accompanied by an adult.
Caution: Always unplug the table before performing any maintenance.
Caution: Check table once a year to make sure all internal and external
bolts are secure.
Caution: The power cord should be located to avoid risk of tripping or
having objects rolled over or placed on top of it. Damaged cords should be
replaced with another of hospital grade.
Caution: Grounding reliability can only be achieved when connected to an
equivalent receptacle marked hospital only or hospital grade.

Basic Table Operation
PreparingtheAFT for yourpatient
Plug your table into any 115 volt grounded outlet (or 230 volt –
international). The Power Switch is located where the power cord exits the
table photo 1). It ships in the “OFF” position. After the table is plugged in,
press the button in to turn the power on.
Paper Roll – Feed the paper through the face cutout, around the paper bar
(just below the cutout) and over the headpiece as shown. Close the paper
cutter located on the side of the headpiece (photo 2) and tear off the excess.
Preparing the Air System (option)
For air models, press the Power button of the main Control Panel (photo 3).
Each of the function buttons will light consecutively and then turn off. The
table’s air-compressor may also turn on to replenish the air-supply. The
compressor will stop when the pressure reaches 90 lbs. See 4.2, “Using Air-
Drops” for air-feature instructions.
If the air-compressor runs for more than 2-3 minutes, call for service (see page 11).
Note: The AFT is equipped with an Auto Shutdown mode which will power down the main control board if the table is inactive for 2 hours. Press the green power button to power the board back up.
Height Pedal
The basic AFT is equipped with a dual Rocker Foot Pedal (#11 under “Product
Features”) which controls the table height from either side of the base. Press
the right side of the pedal to elevate; the left side to lower.
Auto-Touch Foot Pedal (option)
The Auto-Touch Foot Pedal option maintains upward or downward motion even
after releasing the pedal. To operate:
- When the table is at minimum height, double-touch the “UP” arrow and release. The table will continue upward until you tap either side of the pedal again.
- When the table is at maximum height, double-touch the “DOWN” arrowand release. The tablewill continue downward until you tap either side of the pedal again.
- When the table is at any starting height in between, a single-touch up or down will start and stop the motion.
Function Control Panel
For AFTs equipped with air functions, the control panel (photo 3) has a power
button, drop-selector buttons and a thoracic-breakaway button. After power,
press in any order to activate the corresponding function.
Thoracic Release / Thoracic Breakaway Thoracic Release
To operate the Thoracic Release, pull the lever towards youwhile holding the
cushion; adjust to the desired depth. Release the lever to lock the cushion.
ThoracicSpring-Breakaway (Option)
The manual Thoracic Breakaway (non-air) uses a fixed-tension gas shock to
create a recoil movement when the thoracic cushion is unlocked (see photo 4).
Thoracic Air-Breakaway
For tables with a Thoracic Air-Breakaway, it is necessary to regulate the air-
pressure before treating your patient. Follow these steps:
- Select the ‘BRKY’ (breakaway) button on the main control panel (photo 3).
- Unlock the thoracic breakaway switch by pulling toward you until it clicks (photo 4). This will allow the cushion to move freely up and down.
- Press the right side of the Pressure Pedal (#13, page 2) to increase the air-pressure or left side to decrease in the thoracic section. Push down on the cushion as you add air to test for desired firmness.
- Lock the cushion at any point by pushing the thoracic lock switch towards the table until it clicks.
Using Drops
Manual-Drops
Cocking handles are located on both sides of each drop. Lift the cocking
handle up (photo 5, A) to activate the drop. Turn the tension knobs (5, B)
clockwise to tighten and counterclockwise to loosen (also see caution, pg. 6).
Air-Drops Drop Selector Switches
The Drop Selector Switches (photo 6) activate the table drops. You may choose
one or up to four drops simultaneously. Once selected, press the Pressure
Pedal (or optional foot strips, #12, pg. 2) toactivate the drops. After
discharging, press the pedal or foot strip again to immediately reactivate the
drops.
Drop Tension Control Knobs
The Drop Tension Knobs are located on the left side of each drop (#14, pg. 2).
Turn the knob clockwise to increase the firmness of the drop—counter clockwise
to decrease.
Caution: Do not loosen Tension Knobs too far- Adjusting the tension knobs out too far can cause the drops to malfunction. See “Trouble Shooting” section on pg.10 for more detail.
Headpieces
Tilting Headpiece
All AFT models are equipped with a tilting headpiece. The lever for tilting is
located under the front of the headpiece (photo 7, A). It controls the angle
of tilt 30° positive or negative. Pull the lever to unlock; adjust the angle;
release to lock.
Dual-Drop Headpiece
The Dual-Drop headpiece contains two drops—a drop-forward motion and a
straight-down drop.
Important Note: Before changing any of the settings described in the
following section, be sure the headpiece drop is discharged.
Drop-Forward Motion Headpiece
To use the Drop-Forward Motion of the headpiece, the setting lever should
remain in the side channel of the setting mechanism as shown in photo 8. Be
sure that the pin locks into the receiver behind it—otherwise, the drop will
not work. For a manual drop, push up on the black cocking handle to engage.
For Air-Cervical Drop, see section 4.2
Straight-Down Drop Headpiece
To use the Straight-Down Drop action of the headpiece, pull the black setting
lever out and turn it to the left so that it points straight down (photo 9).
For a manual drop, push up on the black cocking handle to engage. For Air-
Cervical Drop, see section 4.2).
Raised Headpiece
The Raised Headpiece allows the headpiece to rise up to 5” above the surface
of the table. It is controlled by a lever in front of the head cushion (photo
7, B). Pull and hold the switch to adjust to the desired height; release to
lock. To lower, apply gentle downward pressure to the thoracic end of the
headpiece with one hand while pulling the lever to adjust.
Cervical Flexion/Distraction
The Cervical Flexion Headpiece includes the raised headpiece feature,
occipital strap and the removable tiller bar.
Note: Cervical Flexion, Distraction and Lateral Motion (described below)
can be used separately or in combination.
Cervical Flexion
Position the patient as shown in photo 10. Secure the occipital strap using
the Velcro® connectors. Use the Tiller Bar to apply flexion.
Cervical Distraction
To use Manual Cervical Distraction you must first unlock the cushion for axial
motion by releasing the red lock pin (shown in photo 11). Pull and turn the
lever to the left.
Cervical Lateral Motion
The Cervical Flexion Headpiece includes lateral motion. To use lateral motion,
locate the switch as shown in photo 12 (or 7C). Pull the lever toward you to
click and unlock. This will allow fullrange lateral movement. The headpiece
can also be locked at any angle in the lateral range.
Translation/CBP Headpiece
To use the translation headpiece, loosen the black knob in front of the
headpiece by turning it counterclockwise. Push the cushion left or right to
the desired position; turn clockwise to tighten the knob.
Flexion & Lateral Motion
Preparing for Flexion
Applying flexion with the Hill AFT is easy. Follow these steps –
Set Up
Position the patient comfortably on the table in the face-down position.
Adjust the slide-out ankle support to fit your patient’s height using the
lever located under the ankle cushion (photo 14). Secure the ankles by firmly
fastening the straps with the velcro connectors (photo 15).Now, have your
patient grasp the gripper bars. The Gripper Bars keep the patient from sliding
during flexion treatment. (10
Using Flexion Using the Flexion Control Panel
All of the controls for flexion are conveniently located at the foot end of
the AFT (see ‘8’, under ‘Product Features’).
Speed Setting – The Auto Flex has a fixed rate of movement from 1-28
cycles per minute (photo 17). Set to desired speed and press ‘Start’
(alwaysstart with a low speed if there is any concern about a patient’s
flexibility). Speed can be changed at any time during the cycle.
Horizontal Switch – The Horizontal
Switch controls how the table behaves when the Stop Button is pushed. If you
want the table to cycle back to the horizontal position when the Stop Button
is pushed, set the ‘Horizontal Switch’ to ‘ON’. If you want the table to stop
immediately at any point in the flexion cycle when the Stop Button is pushed,
set the Horizontal Switch to ‘OFF’.
Start Button – Push to start the flexion treatment.
Stop Button – Push to stop the flexion treatment.
Important: See Horizontal Switch (above) for setting Stop Button
behavior.
Timer – For tables equipped with a timer, flexion can be set to run
automatically for up to 30 minutes (photo 18).
Patient Cut-Off Switch
The patient can stop treatment immediately at anytime using the ‘Patient
CutOff Switch’. The PCO switch is located on the left armrest support (photo
19). Instruct the patient as to the location and function of the switch. To
resume treatment after stopping, press the green Start Button on the flexion
control panel.
Using Lateral Motion
To use Lateral Motion with flexion, insert the flexion handle (tiller) into
the receptacle, just above the ankle cushion (photo 20). Disengage the lateral
lock handle counter-clockwise (photo 21). This will allow the lower part of
the table to move freely from side-toside. You can also lock the cushion
laterally at any point on either side by turning the lock to the 6 o’clock
position. Also, be sure the handle is locked before patient exits the table.
Maintenance
Regular Maintenance
Your Hill AFT is practically maintenance free. There is no lubrication of
parts needed.
Trouble Shooting
Problem
The Cervical Cushion cocks up but does not stay up. The drop pin has come out
of it’s L-bracket.
To Fix:
- Loosen the Cervical Drop Tension Knob enough to rotate the drop pin (see “A”in photo) so that the spring pin (B)faces and engages the bracket(C) as shown in the photo. Once the pin is turned into the bracket, retighten the TensionKnob.
Problem
The main power board is turning off on it’s own. This is likely the Auto-
Shutdown mode operating normally. When the AFT is left inactive for 2 hours,
the Auto-Shutdown mode will power the main control board down automatically.
To Fix:
Simply press the green power button.
Problem
The compressor runs more than 2 or more minutes at a time to replenish the
table’s air supply.
To Fix:
Please call your local dealer or contact Hill Support directly (see below).
Problem
Power Outage:Due to lightning or some other reason, you facility may lose
electrical power from time to time.When this happens, your table’s power
switch will need to be reset.
To Fix:
Unplug the table from the wall outlet and wait approximately 30 seconds. Plug
the table back in to the outlet and then press the power switch in, (see
photo), to the “ON” position
Problem
The table is not responding to the Control Box properly. The problem may be
indicated by the LEDs on the internal electronic drive whichcontrols the
flexion motor. The chart below explains the LED indications.
To view the internal drive showing the LEDs, adjust the table height to the lowest setting and then look under the thoracic section into the table base interior. The electronic drive is mounted to the internal frame scissors.
Important: Surge Protection Recommended
Air functions on this table are controlled by a circuit board and low voltage
valves (see diagrams on the following pages). Since electrical spikes, surges
and undervoltage can be detrimental to electronic components, we recommend
protecting your table with an automatic voltage regulator. While a voltage
regulator will not guarantee parts against failure, it could save you the cost
of parts as well as table downtime. The APC LE1200 voltage regulator is one
example of a device that provides a minimum level of protection.
