2.9 Coupling Device Identification Identify the coupling device on the end of the table top (see Figures 11 and 12). Early versions of the Spinal Surgery Top and Imaging Tops have fixed mounting tubes. Spinal Surgery Tops built after October 1999 and Radiolucent Imaging Table Tops built after January 1997 will have gimbal mounting assemblies (Figure 12). Gimbals allow for rotation of the table top when positioned in extreme lateral tilt and trendelenburg or reverse trendelenburg. Both designs couple to the Hframe in the same fashion. The 5890/5891 Modular Table Bases can utilize either version of the coupling devices but the 5892/5803 Advanced Control Bases must use only gimbal mounting assemblies (Figure 12).

WARNING: Use of table tops on the 5892/5803 Advanced Control Bases without gimbal mounting assemblies (Figure 12) can result in damage to the table top.

3.0 TABLE TOP COUPLING PROCEDURES The Spinal Surgery Top and Radiolucent Imaging Top may be coupled and interchanged to any modular table base, as needed, to provide flexibility and procedural capability. NOTE: For complete instructions on the modular table base operation and functions, please refer to the appropriate owner’s manual supplied with the Modular Table Base. A thorough understanding of the operation of the 5890 and 5891 Modular Table Base is required before continuing. 3.1 5890/5891 Modular Table Bases The following instructions are directed toward the use of a table top on the 5890 or 5891 Modular Table Base. These bases do not have the powered lateral tilt function. 3.2 5890/5891 Patient Transfer Safety Lock Each 5890/5891 Modular Base is equipped with a patient transfer safety lock at both the head and foot end columns. The patient transfer safety lock is actuated by positioning the lever protruding out of the right side of the control box at the head end column (see Figure 13). A second patient transfer safety lock is located on the side of the foot end control box (see Figure 14). When engaged, the patient transfer safety lock prevents rotation of the crossbar by locking the crossbar in the horizontal position. Rotational friction control

NW0504 Rev. E

3.3 5890/5891 Rotational Friction Control The rotational friction control is located at both the head and foot end columns. At the head end, the rotation friction control is the large right-angled lever on top of the head end control box (see Figure 13). At the foot end, the rotation friction control is the black lever that is located on the lower side of the control box (see Figure 15). The rotation friction control may be tightened to act as a friction brake or it can be adjusted to hold the table top at any degree of lateral tilt. As a friction brake, it can be loosened to maintain the desired amount of resistance while still allowing the table top to be adjusted to a different degree of tilt. When completely loose, the rotation friction control will facilitate 180 degree rotations. Rotate the rotation friction control clockwise to increase friction and counterclockwise to reduce friction. It is recommended that the rotation friction control be left in the maximum friction position (fully clockwise) whenever table top movement is not intended.

Crossbar

Rotation friction control

Figure 15: Foot end column (5890/5891 base shown)

NOTE: Because the foot end rotation friction control lever has limited range of movement, occasionally it may not be possible to fully loosen or tighten the brake with one turn of the handle. In that case, once the end of the movement range has been reached, pull the handle down. This will disengage the mechanism and allow the handle to be returned to its starting position without affecting the amount of friction. Repeat the process until the desired amount of friction is achieved. 3.4 Twenty-Five Degree Rotation Stop Each modular base is equipped with a 25-degree rotation stop. The rotation stop is actuated by the lever located on the left side of the control box near the top of the head end column. It can be easily activated with the left hand when standing at the head end of the table (see Figure 16). When engaged, the rotation stop prevents lateral rotation greater than 25 degrees from the horizontal position. The rotation stop should be left in the engaged position and disengaged only during a 180-degree rotation. Crossbar Disengage motion 25 Degree rotation stop

4. Engage the patient transfer safety lock on the head end and foot end columns (see Figures 13 and 14) Warning: For safe patient transfer, the patient transfer safety lock must be engaged prior to transfer in order to prevent the possibility of the table top rotating while the transfer occurs. Failure to do so may result in the patient being dropped. 5. Set the rotational friction control on the head and foot end columns to maximum friction by fully rotating clockwise (see Figures 13 and 15). 6. Set the 25 degree rotation stop on the head end column (see Figure 16). Warning: Prior to coupling the table tops, verify that the two (2) H-frames are properly installed to the crossbar. Confirm the T-pins passes completely through the H-frames and the crossbars and that the T-pin drop locks are in sight and pivot freely. Failure to do so may result in the patient being dropped. 3.6 Selecting The Mounting Holes For The Table Top When selecting the H-frame mounting hole, it is intended that the center of gravity of the patient be at or below the centerline of the crossbars. For most patients, the fourth open mounting hole below the crossbar is the appropriate position (see Figure 20). Centerline of crossbars

To couple the foot end of the table top, slide the H-frame and crossbar as necessary to accommodate the length of the table top (see Figure 22). Align the mounting tube on the table top to the selected hole on the foot end Hframe. Push the T-pin through the H-frame, completely through the mounting tube on the table top and through the opposite side of the H-frame. This should be done at the same level as the mounting hole where the head end was coupled. The T-pin drop lock should be visible and pivot freely.

3.7 5892/5803 Advanced Control Base The Spinal Surgery Top and Radiolucent Imaging Top may be coupled and interchanged to the 5892/5803 Advanced Control Base as needed to provide flexibility and procedural capability. Identify the coupling device on the end of the table top as described in section 2.9, Figures 11 and 12 of this manual. Warning: The Spinal Surgery Top or Radiolucent Imaging Tops used on the 5892/5803 Advanced Control Base must have gimbals (Figure 12). Earlier versions of these table tops do not have gimbals. Use of table tops without gimbals can result in damage to the table top. NOTE: For complete instructions on the 5892/5803 Advanced Control Base operation and functions, please refer to the appropriate owner’s manual supplied with the advanced control base. A thorough understanding of the operation of the 5892/5803 advanced control base is required before continuing. 3.8 5892/5803 Table Control Identification The head end of the 5892/5803 Advanced Control Base is equipped with three indicator lights. These lights are: 1) 180° rotation lock indicator light, 2) tilt drive status light and 3) rotation safety indicator light. Verify that the rotational safety lock switch is in the ON position, and the 180 degree rotation lock lever is in the locked position. All three lights must be illuminated before a patient is transferred to the table.

3.9 Rotation Safety Lock Switch The rotation safety lock switch (with the lighted indicator) locks out the lateral tilt function. This feature is designed to prevent unintended lateral tilt of the table top. The rotation safety lock switch should be turned off only when a 180-degree patient rotation is to be performed. If the rotation safety lock switch is not illuminated, press the rocker switch to the ON position. 3.10 180° Rotation Lock Indicator The 180° rotation lock indicator light, when lit, indicates the 180-degree rotation lock is engaged and the table cannot be rotated 180 degrees. If the 180-degree rotation lock indicator is not on, rotate the rotation lock lever clockwise until the light is illuminated. NOTE: If a 180 degree patient rotation is to be performed, the rotation lock lever should be rotated counterclockwise approximately one half rotation past the point that the rotation lock indicator light goes out. Rotating the lock lever to this point lessens the drag of the friction control, thereby allowing the table tops to rotate more freely during the patient rotation. If even less friction is desired, the lock lever may be rotated further, counterclockwise, as necessary. After the patient rotation is complete, rotate the rotation lock lever clockwise until the rotation lock indicator light is illuminated. Warning: When the rotation lock indicator light is not illuminated, the table top is UNLOCKED regardless of how much the lock lever has been rotated clockwise or counterclockwise. Always rotate the lock lever until the rotation lock Indicator light is illuminated after a 180° rotation. If increased friction lock on the rotation is required, rotate handle in a clockwise direction until desired friction is met. Warning: All three lights must be illuminated before a patient is transferred to the table. If all three lights are not illuminated, do not transfer the patient until they are illuminated. MIZUHOSI 2011

NW0504 Rev. E

3.11 Tilt Drive Status Indicator The tilt drive status indicator light is lit when the power lateral tilt mechanism is in the center position of the +/- 25 degree powered lateral tilt range. If the tilt drive indicator is not illuminated, operate the lateral tilt function using the hand pendant in the appropriate direction until the indicator is lit. The head end crossbar should be horizontal when the tilt drive status indicator is lit. If the head end crossbar is not horizontal, the internal power tilt mechanism is out of synchronization with the crossbar. Refer to the section on synchronizing the lateral tilt function in the 5892 advanced control base user guide or the 5803 owner’s manual, to reset this function. 3.12 Installing The H-Frames The following coupling procedure assumes the head end and foot end columns do not yet have either the Spinal Surgery Top or the Radiolucent Imaging Top in place. The coupling procedure for the Spinal Surgery Top or the Radiolucent Imaging Top is as follows: 1. Lock table base in position by engaging the (4) caster locks. 2. Install an H-frame to head end crossbar and secure with a T-pin (see Figure 25). Fully retract the head end crossbar against the head end column. 3. Install an H-frame to foot end crossbar and secure with a T-pin (see Figure 26). HEAD END
