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.

Symbols

Each of the symbols below are used in your table labeling. An explanation of each is below.

Basic Table Operation

Preparing the 90C for your patient

Plug your table into any 110 volt grounded outlet (or 220 volt – international).

Paper Roll: Feed the paper through the face cutout, around the paper bar (just below the cutout) and over the headpiece (photo 1). Close the paper cutter located on the side of the headpiece and tear off excess paper.

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.

Note: The Air90C 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 90C is equipped with a corded foot pedal which controls the height. The Air90C features a dual Rocker Foot Pedal (#9 under “Product Features”) which controls the table height from either side of the base. Press the right side of either pedal to elevate; the left side to lower.

Auto-Touch Foot Pedal (option)

The Auto-Touch Foot Pedal option maintains upward or downward motion after releasing the pedal. To operate:

When the table is at the lowest 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” arrow and release. The table will 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 Air90Cs, the control panel (photo 2) has a power switch, drop-selector buttons and a thoracic-breakaway button (BRKY). 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 you while holding the cushion; adjust to the desired depth. Release the lever to lock the cushion.

Thoracic Spring-Breakaway

The manual Thoracic Breakaway (non-air) uses a coiled spring to create a recoil movement. First, unlock the cushion (photo 4). Next, firmly pull out on the tension control handle (photo 3) to adjust firmness. Push down for greater firmness; up for less. Push handle back in to lock in desired firmness.

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 Foot Pedal 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.

Raised Pelvic

Both the 90C and the AirC may be equipped with an optional raised pelvic section. To operate, locate the lever under the cushion (photo 6, A). Pull the lever toward you while you lift the cushion. Release the lever to lock it at the desired angle.

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 (photo 5,B) clockwise to tighten and counterclockwise to loosen (also see caution).

Air-Drops

Drop Selector Switches

The Drop Selector Switches (photo 7) activate the table drops. You may choose one or up to four drops simultaneously. Once selected, press the foot strips to activate 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. 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 “TroubleShooting” section on.

Headpieces (options)

Tilting Headpiece

The lever for adjusting the tilting headpiece is located under the front of the headpiece (photo 8, A). It controls the angle of tilt 30° positive or negative. Click the switch in to lock; out to unlock.

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 9. 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.

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 10). For a manual drop, push up on the black cocking handle to engage. For Air- Cervical Drop.

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 8, 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 11. 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 (photo 12). 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 13 (or photo 8, C). Pull the lever toward you to click and unlock. This will allow full-range 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.

Maintenance

Regular Maintenance

Your Hill 90C 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 Tension Knob.

Problem

The main power board is turning off on it’s own. This is likely the Auto- Shutdown mode operating normally. When the Air90C 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.

Control Box

Important

Air functions on this table are controlled by a circuit board and low voltage valves. 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 would provide a minimum level of protection.
