10.0 ADJUSTMENT of COMPONENTS

HEAD END

10.1 Tilt Actuator Rod End Position

1. Loosen lock nut on actuator rod end.
2. Rotate actuator rod until six threads are showing on the rod end.
3. Tighten lock nut.
4. Disconnect the actuator from the base wiring and connect an external power
controller to the actuator.
5. Drive the tilt mechanism all the way right (actuator extended). Watch for clearance
between the actuator rod and the pillow block at the end of actuator travel.
6. If the actuator rod touches the pillow block, re-loosen the locknut and turn the
actuator rod as many turns as necessary to ensure clearance. Retighten the rod
end.
7. Once complete, disconnect the tilt actuator from the external controller and connect
to the base wiring.
10.2 180° Rotation Lock Sensor
1. Remove the blue 180° rotation lock handle.
2. Remove head end cover per procedure; do not unplug electrical connector, hang
cover on table base power cord storage bracket.
3. Loosen 8-32 button head screw securing the 180° rotation sensor (micro switch)
mounting bracket. This is mounted just to the left of the blue 180° rotation lock
handle (see figure 17).
4. Tighten the blue 180° rotation lock handle until rotating crossbar resists 95 ft/lbs
of rotational force in both directions using torque wrench and rotational test bar
(p/n T5890-21/23).
5. Adjust the 180° rotation sensor (micro switch) mounting bracket until the micro
switch clicks on. The "180° Rotation lock indicator" light should be illuminated
blue. Tighten 8-32 button head screw.
6. Test by unscrewing 180° Rotation lock handle until "180° Rotation lock indicator"
goes out. Retighten 180° Rotation lock handle until "180° Rotation lock Indicator"
lights.
7. Retest that rotating crossbar resists 95 ft/lbs of rotational force in both directions
using torque wrench and rotation test bar.
8. If test fails, repeat adjustment procedure.
9. If test passes continue.
10. Install covers per procedure.
11. Install "180° Rotation lock" handle and tighten until "180° Rotation lock indicator"
light illuminates blue.
12. Retest that rotating crossbar resists 95 ft/lbs of rotational force in both directions
using torque wrench and rotation test bar P/N T5890-21-23
13. If test fails, repeat adjustment procedure.
14. If test passes adjustment is complete.
