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
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 variable 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

Breakaway Switch
By law, all trailers with an ATM of 2000kg or greater must have a “Breakaway System” to halt the trailer in the event it
becomes detached from the tow vehicle whilst traveling. Your caravan is fitted with this system with the switch
mounted on the drawbar with a steel wire lanyard to connect to your tow vehicle. In the event that the caravan
becomes detached, the lanyard will pull the pin from the breakaway switch and the onboard batteries will activate the
brake system. The lanyard must be attached to a solid part of the vehicle. It is a mandatory requirement that power be
supplied by the tow vehicle to the breakaway power source while towing. This is done via the 50amp Anderson Plug
on the drawbar. Consult a qualified auto electrician to ensure this is fitted to your tow vehicle.
In NSW there is an additional requirement that the breakaway power source be monitored from the driver position with
a minimum of a “visual alarm” for low battery voltage. Consult a qualified auto electrician to ensure this is fitted to your
vehicle.
