Tip over of patient table Risk of injury
¹ Patient table has to be secured to the transport frame or to the floor
Fig. 102: Patient table drilling template
Pos. 1 Primary holes Pos. 2 Alternative holes Pos. 3 Spacers
NOTE The drilling template has to be positioned directly on con-crete, not on the floor covering.
The floor covering may have to be cut out in some cases to enable the patient table drilling template to be directly placed on concrete.
1. Attach the drilling template with the spacers directly to the gantry and align it with the center of the gantry (Do not use spacers or washers between the drilling template and gantry).
Fig. 103: Template attached correctly
2. Using the angle square, ensure that the drilling template is at a precise 90 degree angle to the gantry.

NOTE The leg length of the angle square has to be at least 200 mm.
Check the 90 degree angle at both sides of the drilling tem-plate.

3. Drill the holes using the guide jacket included in the delivery volume. Ensure that the guide jacket is locked accurately into the drilling template. The drill depth in the con-crete floor must be a minimum of 90 mm.
- Drill depth: Ensure that the screw anchors sit a minimum of 70mm (this value is marked with a serrated ring at the anchor) in the concrete and not just in the floor cov-ering.

NOTE Use the holes toward the center of the drilling template when-ever possible (1/Fig. 102 / p. 106). The outer holes should be considered as an alternative only (2/Fig. 102 / p. 106).
NOTE If you are using the alternative holes, adapt the positions of the adjustable feet accordingly.

4. Remove all dust from the holes with the vacuum cleaner.
5. Position the patient table over the drilled holes so that the adjustable feet (2/Fig. 99 / p. 104)are aligned with the drilled holes.
NOTE The drilling template remains under the patient table as a support plate.
6. Lower the patient table on to the drilling template using the transport frame.
NOTE Risk of patient table overturn!
The transport frames may be disassembled only after the table has been anchored to the floor with screws.
7. Carefully fold the spacer down to the floor together with the table electronics. You have to, however, first remove both transport brackets (Pos. 2/Fig. 116 / p. 117).
8. Using the angle square, ensure that the patient table is at a precise 90 degree angle to the gantry.
NOTE The leg length of the angle square has to be at least 200 mm.
Check the 90 degree angle at both sides of the patient table.
After positioning the patient table at a 90 degree angle to the gantry, check the position of the drilling holes. The drilling holes must be visible through the four adjustable feet of the patient table base plate.
9. Loosen the counter nut at each of the adjustable feet (3/Fig. 99 / p. 104).
10. Alignment with leveling tool
- Turn the gantry by hand until the X-ray tube (at the drum, find the label with “XRT”) is in 6 o'clock position and lock the position using the rotation safety lock. The rota-tion safety lock is located at the gantry front/bottom right (Pos. 1/Fig. 108 / p. 111).

- Position the leveling tool on the plane at the left side of the x-ray tube and on the plane in front of the motor brake of the patient table’s grounding plate.
For the positioning locations see (Fig. 112 / p. 112) and (Fig. 111 / p. 112).

Pos. 1 X-ray tube
Pos. 2 Digital spirit level fixed with adhesive tape
- Fix a digital spirit-level with adhesive tape in the middle of the leveling tool (Pos.
2/Fig. 112 / p. 112).
- Adjust the leveling tool to 0.0° ±0.1° using the transport frame and the four outer adjustable feet.
- After leveling the patient table, screw the four outer adjustable feet to the floor and lower the transport frame.
11. Alignment in X-direction
Level the patient table in X-direction to 0.0° (±0.2°) using the four outer adjustable feet.
Use a digital spirit-level as shown in the figure (Pos. 1/Fig. 113 / p. 113)
¹ The tolerance of ±0.2° is the maximum specification. The adjustment of the patient table should be as close to 0.0° as possible!

Pos. 1 Tilt water level
12. Alignment in Z-direction
Level the patient table in Z-direction to 0.0° (±0.2°) using the four outer adjustable feet.
Use a digital spirit-level in the middle of the top support’s metal frame at each side. For the positioning of the digital spirit level refer to (Fig. 114 / p. 113).

Measure at each side of the top support’s metal frame and evaluate these two values.
For examples of this measurement evaluation refer to (Tab. 2 / p. 114), (Tab. 3 / p. 114) and (Tab. 4 / p. 114).
¹ The tolerance of ±0.2° is the maximum specification. The adjustment of the patient table should be as close to 0.0° as possible!

13. Verifying the alignment
Check the alignment of the PHS again with a digital spirit-level. You must maintain the following tolerances:
- X and Z directions: 0.0° ±0.2°
- Leveling-tool (if available): 0.0° ±0.1°
¹ If at least one direction is not within tolerance you must correct it. After readjust-ment you must check the alignreadjust-ment in X direction, Z direction, and the leveling tool again.
14. Mounting of PHS
Example 1 for an angle measurement in Z-direction:
Patient table orientation
Angle in
Z-direction Note regarding results
Left side -0.4° The patient table adjustment in Z-direction is out of toler-ance on each side.
¹ The patient table adjustment must be improved to 0.0 (±0.2°)!
Right side -0.5°
Example 2 for an angle measurement in Z-direction:
Patient table orientation
Angle in
Z-direction Note regarding results
Left side -0.2° The patient table adjustment in Z-direction is just within tol-erance on each side.
¹ The patient table adjustment should be improved so that it is as close to 0.0° as possible!
Right side -0.2°
Example 3 for an angle measurement in Z-direction:
Patient table orientation
Angle in
Z-direction Note regarding results
Left side -0.2° The patient table adjustment in Z-direction is just within tol-erance on each side, but in different directions (positive angle and negative angle).
¹ The patient table adjustment cannot be improved!
Right side +0.2°
(or +0.1°)
- Tighten all counter nuts for the adjustable feet once the patient table is level.
- Insert the anchor screws with washers 10.5x36x3 and nuts into the drilled holes.
Use a hammer if necessary.
NOTE Anchors of two different lengths have been supplied. Use either the short or the long ones depending on the condition of the underflooring. Also refer to (Fig. 106 / p. 109).
T - Tighten the anchors with 35 Nm using a torque wrench (wrench size 17 mm).
¹ If the threaded pin of the anchor is longer than 15 mm the base cover of the patient table cannot be installed!
¹ If the threaded pin of the anchor is longer than 15 mm, open the nut of the anchor.
Turn the threaded pin with a screwdriver until the excess length is a maximum 15 mm. After this step, you have to tighten the anchor with 35 Nm again.
15. Remove the leveling-tool and unlock the safety lock (Pos. 1/Fig. 109 / p. 111).
16. After anchoring the patient table to the floor, the transport frame of the patient table can be disassembled.
