NON-MOTORIZED MOVEMENTS
WIG WAG
1. Release the Wig-Wag brake.
2. Verify that the forward mechanics pivot to either side of center position.
FLIP FLOP (C-ARM LATERAL MOTION)
1. Release the Flip Flop brake and rotate the C-Arm in a lateral (or “radial”) direction.
2. Verify smooth rotation.
C-ARM ORBITAL MOTION
NOTE: If testing a Super-C system (which does not use an L-Arm), skip to the
Super-C System
section
below.
WARNING
Observe safety procedures when operating mechanical features.
L-Arm (Non-Super-C) system:
1. Release the C-Arm orbital brake and rotate the C-Arm through the bearings in both directions. The
C-Arm should rotate smoothly without roughness or vibration.
2. If roughness or vibration is detected while rotating the C-Arm, first check the bearing races for
contaminants and then remove the C-Arm from the flip-flop assembly and inspect the bearings.
Refer to the
9600 System Service Manual.
Super-C System:
1. Starting with the C-Arm in a position perpendicular to the floor, lock the C-Arm orbital brake,
unlock the flip-flop brake and rotate the C-Arm until the C-Arm is horizontal with the floor.
2. Lock the flip-flop brake, release the C-Arm orbital brake and rotate the C-Arm through the bearings
in both directions. The C-Arm should rotate smoothly without roughness or vibration.
3. Engage the C-Arm orbital brake, unlock the flip-flop brake and rotate the C-Arm 180
°
so that the C-
Arm is again horizontal with the floor.
4. Lock the flip-flop brake, release the C-Arm orbital brake and again rotate the C-Arm through the
bearings in both directions. The C-Arm should rotate smoothly without roughness or vibration.
5. If roughness or vibration is detected while rotating the C-Arm, first check the bearing races for
contaminants and then remove the C-Arm from the flip-flop assembly and inspect the bearings.
Refer to the
9600 System Service Manual.
CROSS-ARM MOTION
NOTE: For Cross-Arm locking on older systems, the Cross-Arm brake shoe presses against the roller in
the Cross-Arm housing. On newer systems, the brake shoe presses against the Cross-Arm itself
(see the illustrations, following pages). Continue with the appropriate sub-section after step 3
