2 INTRODUCTION
If you have any questions or remarks about this manual or about your GreenSteering system, you can always
contact us via [e-mail]. Never make presumptions. When in doubt, always contact GreenSteering.
This document contains guidelines for installing the GreenSteering steering system in order to guarantee the
proper functioning of the system. They are not in any way a guideline for the design of your chassis. This remains
the unique responsibility of the chassis constructor. All common principles, technical calculations, designs, etc.
remain applicable. Drawings and images in this manual that are not directly applicable to the steering system are
merely illustrative and do not entail any indication of the design of the chassis itself.
If you derogate from these instructions, you must always request written permission from GreenSteering. Without
this written permission, any liability will invalidate as well as the guarantee on our products.
