5.0 BASIC OPERATION
The 5803 Base can be operated on AC or DC power. For AC power plug the AC Power Cord
into the proper AC receptacle depending on the voltage requirements of the 5803 Base. Refer to
the label at the Head End Base for input voltage requirements. The 5803 Base can also be
operated on internal battery power with the Power Cord removed or not plugged into an AC
receptacle. Turn the ON/OFF Power Switch to “ON”. A green, "Power On" light, next to the
switch indicates that the power is ON. The ON/OFF Power Switch is a combination power
switch, circuit breaker. To reset this circuit breaker, turn the ON/OFF Power Switch OFF and
back ON.
NOTE: When the power cord is removed and/or not plugged into an AC outlet, the protective
earthing ground stud near the power entry module must be connected to a proper earth ground
during use.
5.1 Casters
Each Base is equipped with three (3) Locking Casters and one (1) Steer Caster. The Steer Caster
functions to allow the Table to roll along a straight path when pushed from the Head End. The
Steer Caster is located on the right side of the Foot End. The Steer Caster has a green label
marked “Steer”. To lock the Table Base securely in place, it is necessary to engage the Lock on
each of the four (4) Casters.
To lock a Caster Lock, step on the Lock Tab until you hear an audible click and the Tab remains
in the down or locked position. To unlock the Caster, push the Unlock Button. When the Unlock
Button is pressed, the Tab will click back to the original unlocked position.

5.2 Control Operation
The 5803 Base is controlled by means of a Hand Control that operates the Up/Down, Lateral Tilt
and Trendelenburg / Reverse-Trendelenburg movements of the table. See Hand Control Section.
The Head End of the 5803 Advanced Control Base is equipped with three Indicator Lights.
These lights are: 1) 180° Rotation Lock Indicator Light, 2) Tilt Drive Status Light and 3)
Rotation Safety Lock Indicator Light. Verify that the Rotation Safety Lock switch is in the ON
position and the 180° Rotation Lock Lever is in the locked position. These indicator lights are
shown in Figure 7. Under normal operation, the ON/OFF power switch light and battery status
light should be lit green and the Fault light should be dark.
NOTE: If the Fault Light is lit, the 5803 Base has detected a fault. Determine fault before use.
Figure 7-Head-end Pivot Assembly, Indicator Lights and Controls
5.3 Rotation Safety Lock
The Rotation Safety Lock Lighted Switch locks out the 180° Rotation function. This feature is
designed to prevent unintended rotation of the Table Top. When the Rotation Safety Lock
Lighted Switch is illuminated, the Table Top can still be Laterally Tilted by pressing the Left or
Right Lateral Tilt button on the Hand Control. The Rotation Safety Lock Switch should be
turned off only when a 180° rotation is to be performed. If the Rotation Safety Lock Switch is
not illuminated, press the rocker switch to the ON position.

5.4 180°-Rotation Lock Indicator
When illuminated, the 180° Rotation Lock Indicator Light indicates the 180° Rotation Lock is
engaged and the table cannot be rotated 180°. If the 180° Rotation Lock Indicator is not
illuminated, rotate the Rotation Lock Lever clockwise until the light is illuminated.
NOTE: If a 180° rotation is to be performed, the Rotation Lock Lever should be rotated
counterclockwise approximately one half rotation past the point that the Rotation Lock Indicator
Light goes out. Rotating the Lock Lever to this point lessens the drag of the friction control,
thereby allowing the Table Tops to rotate more freely during the rotation. If even less friction is
desired, the Lock Lever may be rotated further counterclockwise, as necessary.
After the rotation is complete, rotate the Rotation Lock Lever clockwise until the Rotation Lock
Indicator Light is illuminated.
NOTE: When the Rotation Lock Indicator Light is not illuminated, the Table Top is unlocked
regardless of how much the Lock Lever has been rotated clockwise or counterclockwise. After a
180° Rotation, always rotate the Lock Lever until the Rotation Lock Indicator Light is
illuminated.
5.5 Tilt Drive Status Indicator
The Tilt Drive Status Indicator Light is illuminated when the powered lateral Tilt Drive
mechanism is in the center position of the +/-25-lateral tilt range. If the Tilt Drive Status
Indicator is not illuminated, operate the lateral tilt function using the Hand Control in the
appropriate direction until the indicator is illuminated. The Head-end Crossbar should be
horizontal when the Tilt Drive Status Indicator is illuminated. If the Head-end Crossbar is not
horizontal, the internal power tilt mechanism is out of synchronization with the Crossbar. Refer
to Synchronizing the Lateral Tilt Function to reset this function.

5803 Maintenance and Repair Manual NW0422 Rev G
12
5.6 Hand Control Module
Each 5803 Base is equipped with a push-button hand-held pendant control module (Hand
Control), which is stored on a bracket at the Head-end. The Hand Control allows the operator to
raise, lower, Trendelenburg, reverse-Trendelenburg, and laterally tilt any attached table top. The
selected function will continue to operate until the button on the Hand Control is released.
NOTE: It is recommended that a Table Top always be connected between the Head-end and
Foot-ends of the base when operating the powered controls.
To Raise the Table, depress the Height
Up Button (a) on the left side of the
control with the arrow that points in the
“up” direction.
To Lower the Table, depress the Height
Down Button (b) on the right side of the
control with the arrow that points in the
“down” direction.
To Trendelenburg the Table, depress
the button on the left with the arrow that
indicates Foot Up (c) until the desired
Trendelenburg angle is achieved. This
lowers the Head End Column and raises
the Foot End Column simultaneously. If
the Table is in a fully lowered position,
only the Foot End will rise to achieve the
desired Trendelenburg angle.
To Reverse Trendelenburg the Table,
depress the button on the right with the
arrow that indicates Foot Down (d) until
the desired Reverse Trendelenburg angle
is achieved. This raises the Head End
Column and lowers the Foot End
Column simultaneously. If the Table is
in a fully raised position, only the Foot
End will lower to achieve the proper
Reverse Trendelenburg angle.
To Laterally Tilt To The Left, depress
the Left Tilt Button (e) on the left side of
the control.
To Laterally Tilt To The Right,
depress the Right Tilt Button (f) on the
right side of the control.
NOTE: In the event a large Traction Arc 5855-13 is placed on the Base, the Tilt function has
been made inoperable. However in the event a small Traction Arc 5848-191 is placed on the
base, the Tilt Function is still operable.

Battery Status Light:
•Green = OK
•Red = Needs Recharge.
Fault Indicator Light:
•Electrical Fault = turn Power Switch OFF; disconnect Power Cord.
To unplug and re-attach the Hand Control:
At the end of the Hand Control coiled-cord is a black connector-plug. Unscrew the connector
locking-nut and pull the connector straight out of the socket. To re-attach, insert the connector
into the socket with the notches on connector lining up with the slots on the socket. The
connector locking-nut must be tightened around the socket to insure proper connection.
5.7 Synchronizing The Lateral Tilt Function
Normally, the Head-end Crossbar and left-or-right lateral Tilt Drive-mechanism are
synchronized so that the Tilt Drive is in the middle of its travel range when the Crossbar is level.
It is possible for the Crossbar and Tilt Drive to become unsynchronized if the Crossbar is rotated
manually. Also, the Head-end Crossbar and Foot-end Crossbar can become unsynchronized (not
at the same tilt angle) if a Crossbar is rotated manually or the 5803 Base is operated without a
Table Top in place. The Crossbars must be synchronized to each other, as well as to the Tilt
Drive-mechanism.
NOTE: Never attempt to attach a Table Top to the 5803 Base if the Head-end and Foot-end
Crossbars are not horizontal in all planes. Doing so may cause damage to the Table Top or the
Tilt Drive System.
To verify synchronize of the Tilt Drive and Head-end Crossbar:
1. Confirm that the 180° Rotation Lock is engaged.
2. Confirm that the Rotation Safety Lock is engaged.
3. Use the Hand Control “Lateral Roll” buttons to rotate the Head-end Crossbar until it is level.
4. Confirm the Tilt Drive Status Indicator Light illuminates (on Hand Control or Head-end
Pivot Assembly) indicating proper synchronization.
•If the Light will not illuminate, the Head-end Crossbar and Tilt Drive are not
synchronized.
•If the Head End Crossbar will not level using the Hand Control “Lateral Roll” buttons,
then the Head-end Crossbar and Tilt Drive are not synchronized.
To re-synchronize the Tilt Drive and Head End Crossbar:
1. Turn Power Switch “ON”, the switch illuminates green.
2. Turn the Rotation Safety Lock “OFF”. The illuminated switch goes dark.
Caution – this allows the Foot-end Crossbar to rotate (swing) freely if no Table Top is
attached.
3. Rotate the 180° Rotation Lock-handle counter-clockwise until it is disengaged; the
illuminated indicator light goes dark.
Caution – this allows the Table Top, if attached, or Head-end Crossbar to rotate (swing)
freely.
4. The Tilt Drive mechanism will automatically return to the middle of its range. While this
occurs, you will hear the Tilt Motor (at head-end) running and the Table Top, if attached,
may rotate slightly (if at all). When the Tilt Motor stops running, verify the Tilt Drive Status
light illuminates, confirming the Tilt Drive is in the middle of its travel range. Verify that the
Head and Foot Crossbars are level.

5803 Maintenance and Repair Manual NW0422 Rev G
14
5. If no Table Top is attached:
5.1. Manually level the Head End Crossbar.
5.2. Manually level the Foot End Crossbar
6. Turn the Rotation Safety Lock Switch “ON”; the switch should illuminate.
7. Rotate the 180° Rotation Lock Handle clockwise until it is engaged; the Indicator Light
should illuminate.
8. The Tilt Drive is now synchronized to the Crossbars, and the Crossbars are synchronized to
each other.
5.8 Tabletop Coupling Procedure
The Modular Table Tops may be interchanged and coupled to the 5803 Base as needed to
provide flexibility and specific procedural capability. Position the 5803 Base and engage all four
Caster Locks. Only Table Tops with Gimbals may be used with the 5803 Base.
Figure 9-Jackson Spinal Top & Imaging Top with Gimbal Mounting Assemblies.
NOTE: Verify that the Jackson Spinal Top or the Imaging Top being used has Gimbals. Never
attach a Jackson Spinal Top or Imaging Top to the 5803 Base that does not have Gimbals.

The following procedure assumes the Foot End and Head End Columns do not have Table Tops
coupled in place. The coupling procedure is as follows:
1. Remove the H-Frame from the H-Frame Storage Bracket located on the Head End Column.
Install the H-Frame to Head End Crossbar and secure with a T-Pin. The T-Pins are stored in
the T-Pin Quiver located adjacent to each column. The T-Pin must extend completely
through both sides of the H-Frame and the Drop Lock should be in sight and pivot freely
(See Figure 12). The Head End Crossbar is attached to a Sliding Assembly that adjusts
superiorly and inferiorly to accommodate Trendelenburg and Reverse Trendelenburg. Fully
retract the Head End H-Frame against the Head End Column.
NOTE: If the H-Frame is not aligned with the mounting studs, it may bind. Do not force it. Lift
the H-Frame off and repeat until it mounts easily.
Figure 12-Head-end Pivot Assembly, H-Frame Installed
NOTE: Two people are required to complete the following sequence.
2. Select the appropriate mounting-hole position on the H-Frame to support the tabletop. Hole
selection will differ depending on the top selected and the procedure that would be
performed. Align the mounting tube with the hole in the H-frame and push the T-pin
completely through the H-frame and mounting tube on the foot end.
NOTE: Verify that the T-pin is inserted through the H-frame, passes completely through the
table mounting tube, and through the opposite side of the H-frame and the T-pin drop lock is in
sight and pivots freely. Failure may result in the tabletop being dropped.
3. To couple the Head End of the Table Top, slide the H-Frame and Crossbar away from the
Foot End as necessary to accommodate the length of the Table Top. Align the holes in the
Head End H-Frame and the Table Coupling Device. Push the T-Pin completely through both
sides of the H-Frame and the Coupling Device making certain that the Drop Lock is in sight
and pivots freely. The Head End and the Foot End of the Table Top are normally coupled at
the same hole in the H-Frame. The only exception is when extreme Trendelenburg is needed.

When one Table Top is already coupled to the Base and you are coupling a second Top in order
to change Tops or facilitate a 180° tabletop rotation, the slide mechanism of the Head End
Sliding Assembly will be held in a fixed position due to the fixed length of the first Top. This
requires a different procedure to couple the second Top.
With two people holding the second Top,
1. Attach the Head End H-frame as described above to the Table Top at the desired Mounting
Hole.
2. Position the second Table Top and attach the Head End H-Frame to the Head End Crossbar.
3. Attach the Foot End H-Frame to the Foot End Crossbar surrounding the Table Top Coupling
Device.
4. Connect the Table Top Coupling Device to the Foot End H-Frame at the desired mounting
hole. Verify that the Table Top is coupled at the desired height at the Head End.
5.10 Rotation Procedures
The 5803 Base provides the capability of rotating a tabletop 180°. This is a manually activated
function.
NOTE: At least two people are required to hold and control the rotating motion of the Table
Tops. Prior to rotation, verify that all tabletop coupling devices and H-frames are properly
installed; the T-pins pass completely through the H-frames and crossbars with the drop locks in
sight and able to pivot freely. Four (4) T-pins and drop locks should be visible and checked at
each end of the Table.
5.11 Rotation Lock System
The 5803 Base is designed to engage the Rotation Safety Lock automatically whenever the
ON/OFF Power switch is turned “OFF”. Automatic Rotation Safety Lock engagement ensures
that the Table Top cannot unintentionally rotate laterally without power.
5.12 Rotation Procedure For The 5803 Base
With an attendant at the Head End of the Table:
1. Release the 180° Rotation Lock by rotating the lever counterclockwise until the 180°
Rotation Lock Indicator Light goes out.
2. Advise the attendants holding the tabletops that the Rotation Safety Lock is about to be
released.
3. Release the Rotation Safety Lock by pressing the rocker switch to the OFF position.
Observe that the Indicator Light goes out.
4. Rotate the tabletops.

NOTE: The attendant performing the Rotation must rotate the tabletops 180° toward himself or
herself without stopping until the complete 180° rotation is achieved.
After the Rotation:
1. Immediately engage the Rotation Safety Lock by pressing the rocker switch to the ON
position and observe that the Indicator Light is illuminated.
2. Lock the 180° Rotation Lock by rotating the Lever clockwise until the 180° Rotation Lock
Indicator Light is illuminated.
NOTE:The attendant performing the Rotation may now release the Table Tops.
5.13 Retracting The Base For Storage
The 5803 Base retracts from 120 inches to 73-1/2 inches for storage.
To retract the Base:
1. Lock the Head End Casters and unlock the Foot End Casters.
2. Loosen the Retracting Locking Knob found on the Base.
NOTE:This knob will become completely separated from the Base if turned too far counter
clockwise.
3. Push the Foot End of the Base toward the Head End of the Base until the Foot End is
retracted to its minimum length.
4. Tighten the Locking Knob.
5. Unplug the Power Cord and store it on the Cord Wrap for transfer of the Base. The Base and
Table Top are now ready for storage.

6.0 CLEANING and MAINTENANCE
6.1 Cleaning and Disinfecting
NOTE: The Head and Foot Columns of all the Table Bases are not sealed, therefore:
•Never pour any liquid directly onto the table.
•Never allow any liquid to enter the extensile joint of the columns.
•Never subject the 5803 Table-base to an equipment washing machine.
Failure to thoroughly dry any surface after cleaning and disinfecting may result in rust.
It is important to dry the Base to prevent rusting. Rust formation can prematurely shorten the
useful life expectancy of the 5803 Base.
USE OF IODOPHORS WILL CAUSE STAINING.
Table Exterior:
•Exterior surface should be regularly wiped clean with a mild detergent solution and wiped
dry with a soft lint-free cloth.
•Care should be taken to avoid exposing the table to excessive moisture. Flooding, fogging or
steam cleaning is not recommended and will void any warranty.
•Blood or other fluids, etc., if allowed to remain on the table for a long period of time, will
require special cleaning to remove. A 5% acetic acid solution or white vinegar and water
solution is especially good for this purpose.
•Cleaning with a good commercial cleaning compound, such as Stainless Steel Magic or
Acme White Finish, and then buffing the surface by hand can correct staining and
discoloration of plated or stainless steel surfaces.
•To disinfect exterior surface use a quaternary ammonium or similar type disinfectant
compound according to manufacturer's directions for use. Wipe dry with a soft lint-free cloth.
•Casters should be cleaned and disinfected in the same manner as table exterior.
6.2 Lubrication
Table Exterior:
Following a thorough cleaning and decontamination of the table, silicone lubricant spray may be
used on most of the exposed inner head and foot columns and inner retractable beam. No other
lubrication is necessary.
Table Interior:
All of the internal moving parts of the 5803 Base receive factory lubrication which, under normal
use, provides lubricationfor the life of the equipment.

7.0 THE ELECTRICAL SYSTEM
7.1 Description
The 5803 Base uses an external AC power source or internal, rechargeable, battery power for
operation. It uses AC power when plugged into a proper AC receptacle and the ON/OFF Power-
switch is in the “ON” position. When not plugged in, or AC power is lost, the 5803 Base will
automatically switch over to internal battery power. The batteries are automatically recharged
whenever the 5803 Base is plugged into an AC power source and the ON/OFF power-switch is
in the “ON” position. Located next to the ON/OFF power-switch on the Head End base (see
Figure 4) is the Power On, Fault, and Battery Status lights.
7.2 Power Cord
The table is equipped with a standard EIC power cord with the appropriate 120 VAC hospital
grade connector (230 VAC versions do not include the power connector).
7.3 ON/OFF Power/Circuit-Breaker Switch
An ON/OFF Main Power-switch is mounted at the head end of the base. This switch also serves
as a circuit breaker and in the event of an overload condition this switch will trip off. To reset,
push to the “OFF” position and then the “ON” position. Next to it a green "Power On" light
illuminates indicating that the table power is on.
NOTE: Determine the source of the overload prior to resetting this switch.
7.4 Power ON / Fault / Battery Status Lights
Next to the ON/OFF Power-switch is a small panel of three lights:
•Green = Power ON (AC power or battery power).
•Red = Fault Light (Electrical fault, determine source of fault prior to using table).
•White = Battery Status.
oWhen illuminated Green = installed properly and charged
oWhen illuminated Red = recharging required
7.5 Battery Recharging
The batteries in the 5803 Base are automatically charged whenever the table is in an operational
condition (plugged into AC power source and ON/OFF Power-switch in the “ON” position). No
additional procedures are needed to assure maintenance of the batteries. The “Battery Status”
lamp, next to the ON/OFF Power-switch on the head end base casting, indicates battery charge
condition. If lit, the red “Battery Status” lamp indicates that the batteries require recharging and
the table must be plugged into an AC outlet. If the “Battery Status” lamp remains illuminated red
after about three (3) hours, do not attempt to operate the base under battery power and call for
service (the 5803 Base should remain functional under AC power). It is recommended that, prior
to use, the 5803 Base be plugged into a proper AC receptacle with the ON/OFF switch in the
“ON” position for a minimum of three (3) hours to ensure that the batteries are fully charged.
