Warning

• Check part number or kit is correct for use with your vehicle.
• Do not attempt to fit the rack system to your vehicle unless you fully understand these fitting instructions. Please direct any questions regarding fitting to the dealer from where the roof racks were purchased.
• Off-road conditions can be much more rigorous. Extreme care must be taken on any driven path that does not contain a surface protection layer (tar/bitumen).
• Roof racks must be removed when vehicle is put through an automatic car wash.
• With utility vehicles, the cabin and the canopy move independently. Roof racks and vehicle can be damaged if the item transported is rigidly fixed at points on both the cabin and canopy. Instead, rigidly fix to either the cabin roofracks or the canopy roof racks.
• Always ensure you fasten your load securely.
• Use only non-stretch fastening ropes or straps to attach cargo to your load.

In service maintenance checks

• All bolt connections should be checked after driving a short distance when you first install your roof racks.
• All bolted connections should be checked again at regular intervals (weekly is recommended, depending on road conditions, usage, loads and distances travelled).
• All bolted connections should be checked each time they are re-fitted.
• Off-road conditions are more rigorous. Check all bolted connections and your load more regularly.
• Ensure that your vehicle manufacturer’s GVM, and gross axle weights are not exceeded (refer to vehicle owner’s manual).

Torque Settings
Unless stated otherwise in these instructions, all fasteners should be set to the following torque settings:
M6: 4-5Nm (3-4lbs/ft),
M8: 8-10Nm (6-7.5lbs/ft)
