Orbital Rotation a.k.a. C-arm rotation
Perform the following to verify orbital rotation for standard C-arms and Super C-arms:
1.
On Standard C-arms, release the L-Arm brake and check C-arm rotation in the following positions:
a.
Position the C-arm parallel with the floor and lock the L-Arm brake. Rotate the C-arm through its entire range.
The C-arm should rotate smoothly without vibration.
b.
Position the C-arm on the opposite side and lock the L-Arm brake. Rotate the C-arm through its entire range.
The C-arm should rotate smoothly without vibration.
c.
Position the C-arm vertical to the floor, lock the L-Arm brake and rotate the C-arm through its entire range. The
C-arm should rotate smoothly without vibration.
2.
On Super C-arms, release the Flip Flop brake and check C-arm rotation in the following positions.
a.
Position the C-arm parallel with the floor and lock the Flip-Flop brake. Rotate the C-arm through its entire
range. The C-arm should rotate smoothly without vibration.
b.
Position the C-arm on the opposite side and lock the Flip-Flop brake. Rotate the C-arm through its entire
range. The C-arm should rotate smoothly without vibration.
c.
Position the C-arm vertical to the floor, lock the Flip-Flop brake and rotate the C-arm through its entire range.
The C-arm should rotate smoothly without vibration.
Horizontal Cross-Arm
1.
Release the horizontal Cross-Arm brake and extend and retract the cross-arm. Verify that the cross-arm slides
smoothly through the housing without binding.
Inspect Static Drag Wire
1.
Verify the drag wires underneath the C-Arm and the Workstation are securely attached, are touching the floor and
are free of dirt and debris.
