2. Observe the instructions for the dock leveller and control
   system.

3. Keep these instructions accessible at all times.

4. Only allow authorized and instructed personnel to work on the
   product.

Adjustment:

1. Determine the position X for the sensor holder as per the table
   provided.

2. Reposition the sensor holder by moving it to the required
   position.

3. Loosen the sensor and shift it in the holder for horizontal
   alignment.

Operation and Functional Progress:

Follow the brief instructions provided for operating the dock
leveller. Avoid driving over the dock leveller in the intermediate
stop to prevent injury and damage.

Adjustment

Ensure that the following conditions are met when performing adjustment work: ­ The working area is cordoned off. ­ The control is secured against unauthorised operation. ­ The dock leveller is undamaged and in a proper state. ­ Cables are not kinked, squeezed or damaged. ­ The dock leveller is secured using the maintenance support.

Y Y
1. Measure the required extension range (Y) for the intermediate stop of the telescopic lip. ­ When installed at the factory, the intermediate stop is preset to an extension range of 100 mm. ­ Maximum extension range (Ymax) = distance between front edge platform and front edge buffer
2. Determine the position X for the sensor holder, see table “Determination of position X”.

Determination of position X Position X = extension range Y + table value
