How to Hitch your coupling
Here is a short guide on how to safely use your coupling to couple and uncouple the
trailer from the towing vehicle.
Make sure the handbrake is applied prior to coupling and uncoupling.

8
1300 4X4 4X4
Make sure the dust cap is securely connected to the bump cover. This is done by locating the rear lip on the
dust cap onto the groove of the bump cover and then pushing it in a downward motion until the dust cover is
secure (there should be a slight click when it has been assembled correctly) Test if the dust cover is connected
to the bump cover by applying a slight upward force to the dust cover, it shouldn’t separate.
This procedure should be applied if you are uncoupling or coupling up.

9
1300 4X4 4X4
Coupling
STEP 1
Push down the button (1) and push the locking mechanism back (2). When the locking mechanism (2) is all
the way back, release the button (1) locking the plate in place
STEP 2
Offer up the tow pin to the coupling making sure the tow pin cover is removed and there is no visible debris on
it. Locking plate should be in unlocked position as shown. Lower the coupling onto the tow pin.

10
1300 4X4 4X4
STEP 3
Make sure the tow pin is seated inside the universal and the tow pin top is sticking out of the locking
mechanism (see below). Press the button (1) to release the locking mechanism there will be an audible
locking noise at which point the mechanism will return to the initial position as shown in step 1. Verify the pin is
correctly through the mechanism and assemble the cap. If the cap will not fit check the locking mechanism is
in the correct locked orientation.

Seng up your Caravan
Loading Your Caravan
It is important to load your caravan correctly to distribute weight evenly and achieve a suitable ball weight load and
prevent loading in a manner that can cause a caravan to sway and/or roll excessively left and right. The optimum ball
weight on a caravan is between 9 and 11% of the total caravan weight.
WARNING: BALL LOADING (DOWNWARD LOAD ON TOW HITCH) MUST NOT EXCEED 350KG OR THE
MAXIMUM ALLOWABLE LOAD BY THE VEHICLE MANUFACTURER OR TOW BAR RATING, WHICH EVER IS
THE LOWEST. Exceeding these limits may result in an accident causing serious injury or death and/or
property damage.
•Always load evenly to both sides of the caravan
•Load heavy weight over or as close to over the axle as possible and as low as possible
•Overhead cupboards should only be used for lightweight items such as clothes, personal items, bedding etc.
•Heavy cooking equipment should be stored in lower cupboards.
•Tinned food, bottled goods for cooking etc should be stored in the pantry cupboard.
•Never load in a manner that causes the ball weight to exceed the limit of the tow vehicle.
•Ensure no items can move during travel. Secure all items to prevent damage to the caravan.
•Consider water tank levels and how they may affect the balance front and back and the percentage of ball
weight.
•Never store heavy items in overhead cupboards.
The diagram below illustrates best placements of items based on weight.
Choosing a Spot to Set Up
When choosing a spot to set up your caravan, start with a flat area with no overhanging trees. Birds and bats
occupying trees can defecate leaving droppings on your caravan that can damage paint and leaves and sap can also
stain the coating. Ensure you are not camping in an area prone to flooding or with bad drainage in the event of rain.
Even the slightest hollow in the ground can put you in a mini lake. In hot weather if possible, set your caravan up so
the sun’s arc goes from front to back or back to front with the annex/awning in the general direction the sun is arcing
across. Doing this will keep the bulk of the caravan in shade and the inside cooler as it will be shaded by the awning.

13
1300 4X4 4X4
Levelling Your Caravan
The stabiliser legs on your caravan are not designed for supporting the full weight of the trailer, they are there to
stabilise it once it is level. Using your stabilisers as a lifting mechanism will void your warranty as will extending them
with a “rattle gun” or “impact wrench”. Levelling front to back can be done by raising and lowering the jockey wheel
prior to adjusting the stabiliser legs. Getting the trailer level from left to right should be done with drive on stepped
ramps as illustrated below. Once levelled the legs can be lowered to keep the trailer stable. On soft ground you may
want to use timber sole boards under the stabiliser feet.
Site Power
The Projecta charger in your caravan is connected via the 15A exterior socket. To use site power you will require a
15A power lead connected to a 15A outlet. In the event a 15A outlet is unavailable you will need a conversion box that
will step up from 10A to 15A with a safety switch. Never leave power leads coiled when in use, lay the lead out back
and forward in a manner that won’t be a trip hazard or risk damage to the lead.
Electric Awning
When extending the awning always support to front as it extends. Do not allow the awning to carry the full extended
weight as this may damage the hinges. Support the end manually by hand or by using the extendable legs.

14
1300 4X4 4X4
Leg Rests
The extensions to the lounge area seating are NOT SEATS they are leg rests. Do not under any circumstances use
for seating.
Kitchen
To extend the kitchen from the caravan, press down the blue slide tabs and pull kitchen out. The kitchen will lock into
place when extended. To put kitchen away, again press down the blue tabs and push back into place.
To connect the water and gas, plug the hoses and gas bayonet as per the diagram below.

15
1300 4X4 4X4
Preparing for Bad Weather
During inclement weather the following should be done:
• Close all roof vents and hatches to prevent water entering.
• Protect the awning from high winds by retracting or securing with guy ropes and pegs.
• Ensure your caravan is not parked in ground that will become boggy and prevent exiting the camp area
• Close all external doors and hatches to prevent water ingress and wind damage
Packing Down Your Caravan
When packing down your caravan ensure the following:
•All gas and electric appliances are turned off
•Gas is turned off at the gas bottle
•All loose items are secured and unable to move and damage themselves or the caravan
•All cabinet doors are secured and locked along with all drawers closed
•Roof is lowered, and over centre latches are locked with safety pin engaged
•Site power lead is removed and stowed
•Doorstep is raised and secured
•All roof hatches lowered and secure
•All windows closed and locked
•Main door is closed and locked
•All dust covers in place and secure
Storage & Care
Long Term Storage
To maximise the life of your caravan you should consider additional protection from the elements. UV light and
moisture can have an adverse effect on materials when left unprotected outside. This section outlines some of the
things you can do as an owner to protect your investment.
Interior
Moisture in the smallest amounts can cause mould. High humidity and cooling temperatures can create condensation,
additionally condensation can form under mattresses due to temperature differences between warm bodies on top and
the bed base being cold from outside temperatures. As a precaution you can do the following:
•Check under mattress for moisture before packing up. If moisture is found allow to thoroughly dry before
closing your camper.
•Store 1 or 2 moisture absorbing packs/dehumidifier packs in the caravan to draw away any residual water
vapour.
•If packing up with damp or humid conditions, open and dry out the caravan at the first opportunity when
returning home.
Exterior
Ensure all seals on the caravan have proper compression at 30-50%, are free of dirt and have nothing protruding past
the seals. UV light and the elements can over time cause seals and fittings to perish and become brittle. The use of a
caravan cover will extend the life of components and keep your investment looking better for longer.

16
1300 4X4 4X4
Securing Your Caravan
When parked and unhitched you should always use suitable wheel chocks to ensure the trailer can’t move in the event
of a handbrake failure. For security a wheel clamp or and hitch lock are highly recommended.
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 with 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

17
1300 4X4 4X4
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
Trailer Plug Wiring
The following diagrams outline the correct wiring for 7 pin plug
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

18
1300 4X4 4X4
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.
Breakaway Switch Anderson Plug
CAUTION:
•DO NOT CONNECT THE BREAKAWAY LANYARD TO THE SAME POINT AS THE SAFETY CHAIN
SHACKLES.
•DO NOT USE THE BREAKAWAY AS AN ALTERNATIVE TO THE HANDBRAKE AND DO NOT REMOVE
THE PIN AS AN ALTERNATIVE SECURITY MEASURE. REMOVING THE PIN WILL RAPIDLY DISCHARGE
THE BATTERIES.
•IT IS A MANDATORY REQUIREMENT THAT THE BREAKAWAY BATTERY SOURCE BE CHARGED
DURING TOWING.
•NSW REQUIRES A BATTERY MONITOR VIEWABLE FROM THE DRIVERS POSITION WITH A MINIMUM
OF A VISUAL ALARM FOR LOW BATTERY VOLTAGE
Hand Brake
Parking brakes are mechanically operated by cable means. The cable attachment occurs outside of the brake backing
plate. Cable force applied to the parking lever creates a torque through the pivot pin and cam assembly. Torque
transferred to the parking cam results in a spreading force between the primary and secondary shoes. The shoes in
turn, move towards the drum until contact is made. Friction generated between the drum and lining contact surface
results in parking brake capability.
Use the cable adjuster to give enough tension to be able to set the handbrake lever on the last two notches of the
coupling or handbrake is 1/3 raised when unladen. This needs to be checked again when the trailer or caravan is
loaded. If the cable is too tight, the brakes will be applied as the axle moves backward under spring deflection.

19
1300 4X4 4X4
Adjuster
To adjust the handbrake cable tension release locknuts A, B and C in the diagram Handbrake Adjuster 1 below. To
tighten the handbrake cable, turn the adjuster wheel D in a clockwise direction. Once adjusted retighten lock nuts and
test. Always ensure that wheels turn freely when handbrake is off. Overtightened cables can cause brakes to drag and
damage the brake linings.
