Definitions
The table below defines the meaning of various symbols used on labels on
the machine.
This warning symbol is used to indicate a
potential hazard to operators, service per-
sonel or equipment. It indicates a requirement
to refer to the accompanying documentation
for details.
This symbol indicates that there is accessible
dangerous voltage.
This symbol identifies a protective earth termi-
nal.
This symbol states that this product is catego-
rized as Type B.

Safety Conventions Used in this Manual
Specific safety information is listed in this manual in the form of
WARNING and CAUTION statements. Pay close attention to these
statements - they contain important information on avoiding potential
hazards to you or the equipment.

• have a triangular symbol with an exclamation point above the text.
• are preceded by the word Warning.
• are always found before the step or piece of information to which they
refer to.
• look like the following example:
Warning
Turn off electrical power to table at power source before servicing
table. Also, make sure that power source is locked out and tagged
“Table Being Serviced” before servicing table. You could get
seriously shocked or burned if you do not.

ii-6 Equipment Safety Guidelines
Equipment Safety Guidelines
The following warnings and cautions are specific to the EV-650 Elevating
Table. Read them carefully - some of them are not obvious to typical
equipment use.
Warning
Turn off electrical power to table at power source before servicing
table. Also, make sure that power source is locked out and tagged
“Table Being Serviced” before servicing table. You could get
seriously shocked or burned if you do not.
Warning
Do not place any objects within the vertical motion area above or
below table. Objects in such areas can present crush hazards for
the patient or operator and can also damage the table. See areas
shown shaded in Figure below.
The table is equipped with a collision avoidance switch for
downward motion. This switch, however, is designed to protect
the table, not the operator or patient from a collision. The
downward motion of the table will stop if the table encounters 100
lbs (44kgs) of upward force.

Equipment Safety Guidelines ii-7
Warning
Make sure that the operator or the patient does not touch the table
unlock pedals when the patient is getting on or off table. This may
cause the patient to fall off the table and cause serious injury. See
Figure below.
Warning
Do not operate the table in an explosive atmosphere (such as
anesthetic gas). Doing so can cause an explosion or fire hazard
causing serious injury.
Unlock Pedals

ii-8 Equipment Safety Guidelines
Warning
All of the movable assemblies and parts of this equipment should
be operated with care and routinely inspected in accordance with
the manufacturer’s recommendations contained in this manual.
Only properly trained and qualified personnel should be
permitted access to any internal parts. Live electrical terminals are
deadly; be sure line disconnect switches are opened and other
appropriate precautions are taken before opening access doors,
removing enclosure panels, or attaching accessories.
Do not remove flexible high tension cables from X-ray tube
housing or high-tension generator and/or access covers from X-ray
generator until the main and auxiliary power supplies have been
disconnected.
For all components of the equipment, protective earthing means
must be provided in compliance with the national regulations.
Warning
This table is intended to be used as part of a system for the
intended generation of X-rays for medical diagnosis.
X-rays generate a potential risk for both patients and operators.
For this reason, the application of X-rays for a given medical
purpose must aim at the minimization of radiation exposition to
any persons.
Those persons responsible for the application must have the
specific knowledge according to legal requirements and
regulations and must establish safe exposure procedures for this
kind of systems.
Those persons responsible for the planning and installation of this
equipment must observe the national regulations.

Emergency Stop Button (For Service Technicians Only) ii-9
Emergency Stop Button (For Service Technicians
Only)
There is an Emergency Stop Button located in the table’s base that can be
pressed to stop the motion of the table in an emergency. It is meant only to
be used by technicians who are troubleshooting the table.
If the button is pressed, it must be turned in the direction of the arrows on
the button until the button pops back up in order to reset the button.
Otherwise, the table cannot be restarted. See Figure below for location of
button.
Warning
The Emergency stop button DOES NOT turn off all power to the
table. There may still be lethal voltages present on the main
chassis and throughout the table when this button is turned off.
These voltages come from sources outside the table ( i.e. generator,
wallstand, etc.) that are connected to the table.

Introduction
1.1 Introduction
This manual provides installation, operation and service information for
the EV-650 Elevating Table. This manual also includes a spare parts list for
the table.
1.2 Description
The EV-650 elevating radiographic table is designed for general purpose
radiography and is ideally suited for modern hospitals, urgent care
centers, clinics and private practices.
The EV-650 features a four-way, floating table top which provides 40” (102
cm) of longitudinal travel and 9.0” (23 cm) of transverse travel. It has a
motor driven telescopic base which permits the tabletop to be lowered to
within 22” (55.9 cm) of the floor and raised to a maximum height of 34”
(86.4 cm) above the floor.
Electro-mechanical locks maintain the desired position. The position of the
table top can be raised and lowered, and the locks released by operating
the foot pedals. The table’s bucky can also be repositioned by pressing the
pushbutton.

Caution
Do not drill equipment mounting holes in pre-tensioned or post
tensioned concrete floors before determining the location of the
tensioned wire ropes. Consult with customer or responsible
project engineer to locate and avoid drilling through wire rope.
Cutting through tensioning cables can cause severe structural
damage.
Note: Bolt hole locations and overall base
dimensions are symetrical unless
otherwise dimensioned.
