Disassembly 1. Prepare the operating table (see chapter 7 on page 29).
2. Switch off the operating table and disconnect the internal
power supply (see chapter 10 on page 33).
3. Remove the pad plate of the seat section (see chapter 12.2 on
page 40). Important: keep the back section pad plate
attached so that the bar adjustment is retained.
4. Remove the cover from the center box (see chapter 12.3 on
page 41).
5. Loosen the toothed belt tension. Loosen the attachment
screws [2] on the motor [1].
6. Take the toothed belt [3] from the toothed belt pulley on the
gear and on the motor.
Assembly
Precisely place the toothed belt around the toothed belt pulley
on the gear box and motor.
2. Tighten the toothed belt [3]:
a) Attach the longitudinal travel motor to the center box (2
screws).
b) Check the toothed belt tension with a belt tension meter.
The value must be 140 Hz (±5 Hz). Slide the motor if the
value is different (loosen the attachment screws [2] on the
motor).
c) Attach the longitudinal travel motor [1] in the center box of
the table top (2 screws [2]). The axle [5] of the motor must
be parallel to the shaft [4] of the gear box.
d) Check the toothed belt tension and reset if there are
differences. The value on the belt tension meter must be
140 Hz (±5 Hz).
3. Calibrate the longitudinal travel motor (CAN test center) See
chapter 24.5 on page 267.
