GENERAL INSTRUCTIONS
Use this procedure in conjunction with the C-Arm Periodic Maintenance (PM) Report/Checklist 00-
884521-01. Enter the required information at the top of this form (“Customer Name”, “Street”, etc.) prior
to performing the PM test procedures. During testing, place a check mark next to each test completed,
and (where applicable) record the measured values; if adjustments to these values are made, note them on
the form in the comments section.
Note that the numbered sections and their titles in this document match those on the C-Arm PM
Inspection Report form.
Required tools, test equipment, paints, torx screw specs., lubricants, and adhesives are listed near the end
of this document, in section 6 (“Test Equipment Used”); refer to the Contents on the previous page.
Log all test equipment used on the PM Inspection Report form in the #6 block near the bottom, “Test
Equipment Used.”
NOTE: Test equipment must have current calibration dates. Do not use test equipment with expired
calibration stickers.
The Series 9600 has been through several product iterations, and thus there are differences between older
systems and those manufactured today. The information contained in this version of the manual is
accurate at the time of the manual’s release; however, product changes and improvements can occur at
any time and may not be reflected here.
This document distinguishes differences between systems by referring to the systems serial number
and/or date of manufacture, or by citing different product lines such as standard or Super-C/Cardiac
systems.
To aid in these procedures, refer (if necessary) to the 9600 System Service Manual, p/n 00-878772.
Read the following “Safety” section, perform the procedures in the “Preparation” section, then begin the
tests with section 1, “Safety Inspections.”
SAFETY
INGRESS OF WATER AND SOLUTIONS
The system must never be operated or stored in locations where conductive fluids, like water and saline
solution, might spill on the equipment.
Always unplug the AC power cable from the wall outlet before cleaning the equipment. Do not allow
water, soap, or other liquids to drip into the equipment and cause short circuits, electric shock and fire
hazards.
UNAUTHORIZED MODIFICATIONS
Under no circumstances should the safety interlock in the system be bypassed, jumpered, or otherwise
disabled.
NOTE: All OEC systems comply with International Electrotechnical Commission safety standard IEC-
601. Do not connect any external device to the system that does not meet the requirements of
IEC-601. Only devices provided or approved by OEC Medical Systems, Inc. should be
connected to the system.

MOTORIZED MECHANICAL OPERATION
The Vertical Column and L-Arm are motorized. Observe them continuously while operating their motors
to avoid collision with people and equipment. (Note that the Super-C system does not use an L-Arm.)
If covers are removed, use extreme care when operating motorized features. Do not wear loose clothing
that may be caught by gears or chains. Keep hands and fingers clear of motorized equipment while the
motors are in operation.
TRAINED SERVICE PERSONNEL
Serious injury and property damage can result from incorrectly performed service procedures. Observe
all operating and safety procedures discussed in this document.
WARNING Procedures should be performed by service personnel specifically trained by OEC
Medical Systems, Inc. to calibrate the Series 9600 System.
ELECTRICAL SHOCK
WARNING This system can generate lethal voltages. Observe safe electrical testing procedures
when performing periodic maintenance procedures.
WARNING After taking X-rays, the high voltage cables can retain a lethal charge, even if you
power down the system. High voltages can arc several inches from their terminals if
the cables are removed from the connector wells. Use caution when disconnecting
high voltage cables even when the power is turned OFF. If you remove these
connections, immediately discharge their contacts against the high voltage tank case
(ground).
WARNING Use caution when working near the batteries and their connections. Remove metal
rings and watchbands that may inadvertently come in contact with the battery
terminals. Severe skin burns could result if such metal articles were shorted across
the battery terminals.
X-RADIATION EXPOSURE
The X-ray tube assembly produces X-radiation when energized. Never operate this device without X-ray
shielding in place. Use lead shielding and draping to protect personnel.
WARNING Lead aprons, radiation monitors and appropriate radiation shields must be utilized
by personnel while performing tests. Living human anatomy should never be used
as a phantom or demonstration aid.
CAUTION Many of the PCB's in this system contain components which are sensitive to Electro-
Static Discharge (ESD). Observe ESD safety procedures.

This symbol indicates that equipment is non-anesthetic proof and should not be operated in the presence
of flammable vapors, liquids or other substances.
PREPARATION
REMOVE POWER AND COVERS
WARNING Electrical circuits inside the equipment use voltages that are capable of causing
serious injury or death from electrical shock. Use appropriate precautions.
1. If the system has power applied, turn the Workstation keyswitch to the OFF position, then unplug
the Workstation's AC power cord from the wall outlet.
2. Remove the Workstation rear cover, left side cover, and open the electronic card rack rear door.
Refer to the 9600 System Service Manual.

3. C-Arm cover removal is different for (older) systems without center pivot steering and those (newer)
systems equipped with center pivot steering.
For older systems without center pivot steering: remove the front leg cover, right front cover, left
front cover, top front cover, and rear cover. Refer to 9600 System Service Manual (and see the
illustration below).
For newer systems with center pivot steering: remove the front leg cover, right front cover, left front
cover, and top front cover. Then loosen the 2 upper set screws on the steering shafts’ compression
coupler so the upper shaft is disconnected from the lower shaft and the rear cover can be removed
freely, then remove the rear cover. Refer to 9600 System Service Manual (and see the illustration,
next page).
