General Instructions
Use the following procedures to perform periodic maintenance on the MINI6600 Mobile Imaging System. The
MINI6600 Periodic Maintenance Form must be completed as the procedures in this manual are performed. If the
system does not pass a portion of the procedure, correct the problem before completing the PM Form. Note all
failures and the corrective action taken in the comments section of the PM Form. Additional space is provided at
the end of the PM Form.
The tools and test equipment that are required to perform Periodic Maintenance, are described in Appendix A.
All Torx screws have recommended torque specifications. These specifications are described in Appendix A.
IMPORT ANT:
The PM Procedures do NOT list all the steps necessary to complete the PM.
The service engineer WILL NEED the Service Manual (00-878315) to complete the PM.

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.
Mechanical Operation
The Articulating arm is manually adjusted.
T rained Service Personnel
Serious injury and property damage can result from incorrectly performed service procedures. Observe all operating and safety procedures contained within this manual.
W ARNING:
Procedures contained in this manual should only be performed by service personnel
specifically trained by OEC Medical Systems, Inc. to calibrate the MINI6600 System.

Electrical Shock
W ARNING:
This system is capable of generating lethal voltages. Observe safe electrical testing procedures when performing periodic maintenance procedures on the system.
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.
W ARNING:
Lead aprons, radiation monitors and appropriate radiation shields must be utilized by personnel while performing tests.
CAUTION:
Living human anatomy should never be used as a phantom or demonstration aid.
Many of the PCB’ s in this system contain components which are sensitive to Electro-Static
Discharge (ESD). Observe ESD safety procedures.

Completing the PM Form
1. At the top of the MINI6600 Periodic Maintenance Form, check whether you are performing a SemiAnnual or an Annual PM.
2. Completely fill in the customer information block, including the T ime Of Day (start time) measured in
military time, System Serial Number and the Field Service Report (FSR) / Request ID Number . Indicate
the system configuration with appropriate check marks.
NOTE:
T est equipment used must have current calibration dates. Do not use test equipment with expired
calibration stickers.
3. While performing the Periodic Maintenance procedures, log all test equipment used in the Test Equipment Used block of the Periodic Maintenance Form.
4. Place a check mark on the PM Form as each test paragraph is completed. Fill in actual measured values where indicated on the PM Form. If adjustments are made, note the adjustment in the comments
section of the PM Form.

Begin Periodic Maintenance
Remove the Power And Covers
W ARNING:
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, position the System keyswitch/pushbutton to the OFF position. V erify
that the System’s AC power cord is not plugged into the wall outlet.
2. Remove the System covers. Refer to the System Overview section in the MINI6600 Digital Mobile CArm Service Manual (00-878315) for cover removal procedures.
Elapsed Time Indicator
Read the elapsed time meter on the System and enter the number on the PM Form.
Inspect the Static Drag Wire
1. V erify that the static drag wire underneath the System is touching the floor.
2. V erify the static drag wire is securely attached.
Inspect the Articulating Arm and Brake
V erify that the articulating arm mechanics move freely and smoothly throughout the entire range of
motion.

Inspect the Rotation Brake
1. Release the rotation brake and rotate the MINI-C assembly.
2. V erify smooth rotation.
3. V erify that the brake locks the mechanics in any position within the range of motion.
Inspect the Orbital Brake
1. Release the orbital brake.
2. Move the MINI-C throughout the orbital range. Ensure smooth operation.
3. V erify that the brake locks the mechanics in any position within the range of motion.
Verify the System Steering And Brake Operations
1. Select the LOCK mode by pressing the steering brake pedal completely down. V erify that the casters
and wheels are locked in position and do not move.
2. Select the FREE mode by lifting the steering pedal up halfway . Verify that the casters rotate and the
wheels roll freely .
3. Select the STEER steering mode by lifting the steering pedal completely up. V erify that the casters
rotate into the steering position and lock, and the wheels roll freely.
