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.

COVER REINSTALLATION WHEN PM PROCEDURE IS COMPLETE

1. When all necessary steps are complete and access to components beneath the covers is no longer

required, reinstall all previously removed covers in reverse order from which they were removed.

If the system is equipped with center pivot steering, use the following procedures for reinstallation of
the mainframe rear cover (and refer to the illustration below):

A. Position the rear cover so the upper steering shaft can fit into the compression coupler on the lower

steering shaft.

B. Position the rear wheels forward, then slide the upper shaft into the coupler to where there is a 1/4-

inch to 3/8-inch gap between the ends of the shafts.

CAUTION: Be sure the wheels are positioned forward (straight) and the set screw heads face directly

front when inserted in the couplers before securing the couplers to the shafts. If not
installed in this front-aligned position, there is a chance the set screw heads could scrape
against the inside of the right front cover when turning the wheels to the right.

C. Align the steering handle with the rear wheels, then tighten (but do not Loctite) the two upper set

screws on the coupler and torque them to 48 in.-lbs. Or, if using a torque screwdriver, torque to 39
in.-lbs. max., then 1/8-inch more turn with an allen wrench.

D. Reinstall the mainframe rear cover, top front cover, left front cover, right front cover, and front leg

cover.
