KEY POINTS ON INSTALLATION
• A position should be chosen convenient for the steering system
hydraulic delivery lines.
• The site should be rigid and flat to prevent excess vibration.
• Shielded from the direct effects of the elements.
• Minimise the lengths of the hydraulic lines from the pump to the
cylinder and where possible the pump motor supply cables.
