15.3 Procedure
Figure 1-74 Gantry Tilt Bracket Removal
1.) Refer to Figure 1-74. Remove the M12 bolts using a 10 mm Hex wrench.
2.) Loosen the M16 bolt 1-2 turns and check the Gantry tilt bracket, it should be loose to the touch.
If loose continue with step 4.
CAUTION Potential for personal injury.
If tilt bracket is not loose, stop and put the M12 bolts back in and tighten tilt bracket back in
place. If there is a load on the tilt bracket, removal may cause the gantry to suddenly tilt all
the way back due to a possible lack of hydraulic pressure.
3.) Check the hydraulic connections for leaks or lack of fluid. You will have to wait until the system
can be energized to use the tilt controls to relieve the load on the tilt bracket prior to removal.
Do not use force to remove the bracket.

5.) Remove the bracket.
6.) Close the gantry covers and reinstall the scan window.
