GENERAL CARE AND MAINTENANCE
By choosing an ARB set of side rails, you have bought a product that is one of the most sought after 4WD
products in the world. Your side rails are a properly engineered, reliable, quality accessory that represents
excellent value. To keep your side rails in original condition it is important to care and maintain it
following these recommendations:
Prior to exposure to the weather your bar should be treated to a Canuba based polish on all exposed
surfaces. It is recommended that this is performed on a six monthly basis or following exposure to salt,
mud, sand or other contaminants.
As part of any Pre Trip Preparation, or on an annual basis, it is recommended that a thorough visual
inspection of the side rails and bull bar is carried out, making sure that all bolts and other components
are torqued to the correct specification. Also check that all wiring sheaths, connectors, and fittings are
free of damage. Replace any components as necessary. This service can be performed by your local
authorized ARB Stockist.
