IX. Replacement of the limit switches (Model 504225) There are 3 limit switches, needed for the shifting of the table. 2 control the length of the way and 1 prevents collisiones with the column when adjusting the back plate. To replace the limit switches, the expansion bellow has to be loosen first (as described in chapter III of this manual) To replace the limit switches, do as follows:
The limit switches will be replaced as a complete set, because the 3 limit switches are all connected with one Sub-D plug. Loosen the Sub-D plug from the distribution panel and remove all cable ties and stress reliefs of the cable bundle for the limit switches. Loosen the limit switch for avoidance of colisiones with the back plate first. You can find it in the right rod on the aluminium profile rail. Remove the aluminium rail by removing the 2 fastening screws on the right and left. To reach the screws, the upper frame has to be moved until the screws are visible.

Now loosen the 4 screws of the bottom, which join the lift column to the base of the table. Advice: For better accessibility, we recommend to use squared timbers to support the table. After that, the screws can be removed easily. When unscrewed, the complete lift column can be taken off. fig. 78: Dismantling of the lift column
Attention: Make sure all cables on the column and connection cable are removed, so that other cables won´t be damaged! Before installing the new lift column, you have to dismantle the following components from the old one: - Holders for the motor for Trendelenburg adjustment and pull spring for stabilization - Base plate
fig. 79: Lift column dismantled
Therefore, loosen the respective 5 screws on the holder, as well as the 8 fastening screws at the bottom of the base plate. The screws marked with green arrows are fastened on 2 bolts inside the column. Make sure the bolts are visible, when dismantling the lift column.

XIV. Dismantling of the Shifting (only Model 504225) If the shifting function of the table doesn´t work or is damaged, do as follows: Remove the upholstery, the cover and loosen the expansion bellow from the upper frame (as described in the respective chapters of this manual). After that, do as follows:
Make sure whether the connection of the motor to the control still exists. If a connection error can be ruled out, the motor for shifting has to be replaced.
fig. 92: dismantle motor (shifting)
To replace the motor it is important to be able to reach the fastening screws. In case the upper frame is in a position where you can‘t reach the screws it is necessary to move the table in the right position (in direction of the leg plate), by using the spindle.
fig. 93: dismantle motor(shifting)
When visible, the two screws have to be loosen. Now the motor is uncovered.

Now the two accumulators are visible. Remove the screws on the top of the fastening plate. It is seated on the accumulators and therefore fastens the accumulators on the base (with screws).
fig. 97: Dismantling accumulators
After dismantling the plate and loosing the cable lugs, the accumulators can be pulled off the base.
fig. 98: Dismantling accumulators
Should the battery charging unit for accumulators be defect, please replace the black box (which is fastened with adhesive tape) between control and accumulators.
