Torque Settings
Wheel Nuts
Wheel nuts should be tightened to correct torque using a torque wrench. Never trust a “rattle gun” as these may
over or under tighten. A quality torque wrench will ensure nuts are tightened correctly. It’s important to remember
to check your wheel nuts at 50km, 500km and 1000km and periodically thereafter. The correct torque setting of
125Nm for 12mm studs, 140nm for 14mm studs and alloy wheels and 200nm for 14mm studs with steel rims.
Refer to the plate on your drawbar.
Hitch
The high tensile bolts securing your hitch should be tightened to 76Nm. These should be checked at 5000km
intervals or 2500km in harsh off-road conditions.
Trailing Arm Pivot Bolts
The pivot bolts are a high tensile steel. The service interval for these bolts is 5000km under normal use and
2500km for harsh off-road conditions. During travel they should be inspected daily to ensure they have not rotated
or become damaged. Correct torque is 190Nm
Brakes and Handbrake - Electric
Features
Your trailer is fitted with electric brakes that require a brake controller that can be operated from the driver’s seat.
1. Manual adjusted to provide the correct braking capability for varying road, off-road and load conditions.
2. They can be modulated to provide more or less braking force, thus easing the brake load on the towing vehicle.
3. There is very little lag time between the moment the tow vehicle’s brakes are actuated and the moment the
trailer brakes are actuated.
4. They can provide some braking independent of the tow vehicle in the event of an emergency.
Operation
When electrical current is fed into the system by the controller, it activates the electromagnets in the brakes. These
electromagnets are energized and are attracted to the rotating surface of the drums which moves the actuating
levers in the direction that the drums are turning thus applying pressure from the brake linings to the drum surface
