Please note: To replace the dust protection tube on the manual, telecentric zoom, the zoom adapter must first be detached from the lower lens section. To do this, three Allen screws must be loosened. It is important that the zoom system is thoroughly cleaned on the outside before loosening the screws so that no dust can penetrate the lens parts.

Important: Once you have detached the lower telecentric lens section, it is essential to readjust the centricity of the system. If you have not received training on how to do this, we recommend that you send in the zoom system for replacement of the dust protection tube.
