Coupling the caravan to your tow vehicle
Make sure that the caravan coupling height is approximately the same as the tow vehicles tow ball
height. Reverse the tow vehicle as close as possible to the coupling head of the caravan. While
holding the caravan in place, release the overrun handbrake lever, then by pulling on the grab
handles manoeuvre the caravan so that the coupling head is directly above the tow vehicles tow ball
then apply the caravan handbrake. Now pull up on the caravan coupling lock handle and lower the
height of the caravan by winding the jockey wheel down.
Once the caravan coupling has engaged the coupling lock handle will lock down into place. You will
see the green lock indicator will pop out at the front of the coupling head to indicate that the handle
has lock down into place. (As seen in fig 1 unlocked and fig 2. locked).
Clip the brake safety cable around the tow vehicles tow ball where it will hang loosely. The function
of this cable is to pull the handbrake lever up in the event that the caravan accidentally uncouples
from the tow vehicle when you pull away. Once the caravan is coupled securely you may release the
caravan overrun handbrake lever.

Wheels and Tyres
The tyres of the OKTO caravan should be inflated to 2.6 Bar, and checked before each trip.
It is advisable to inflate the tow vehicle as follows: Rear tyres 2.5 Bar and front tyres 2.2 Bar.
The wheel nuts should be checked and torqued to 95N.m before each trip. It is important to stop
and check wheel nuts of a new OKTO every 100km for the first 1000km. This will provide enough
time for the wheel nuts to seat into the rim.
If you need to change your wheel in the event of a puncture, follow the next procedure:
•Remove the spare wheel from its cradle as shown below.
•Place chocks on either side of the non-punctured wheel.
•Pull up the handbrake lever.
•Loosen the wheel nuts of the punctured wheel, but do not remove them yet.
•Wind the jockey wheel so that the nose of the caravan is as low as possible.
•Wind the rear corner steady on the side that has the punctured wheel down and exert
approximately three winds of pressure onto the steady after it has touched the ground.
•Now wind up the jockey wheel as high as it can go. This should lift the punctured wheel
off the ground.
•You can now loosen the wheel nut completely and remove them. Take off the wheel
and fit the spare.
•Follow the same procedure but in reverse and make absolutely sure you have double
checked that the wheel nuts are tight.
How to Remove the Spare Wheel
•Drop the nose of the caravan down as low as you can to provide enough space for the
spare wheel to past out underneath the wall of the caravan.
•Remove the clip and undo the locking fly-screw holding the spare wheel cradle in
place.

•Reaching from the side of the caravan pull the handles gently towards you until the
cradle drops to the ground. As shown in Fig. A. below.
•Then move back and pull the handles towards you until the cradle is extended fully.
You should then be able to reach the wing nut and retaining plate and remove the
spare wheel from the cradle.

The Braking System
The OKTO caravan is fitted with AL-KO Automatic Reversing Hubs.
When the overrun handbrake is pulled up and the caravan is moving in a forward direction, the
brake shoes shift into a forward position in the hub and the caravan will brake. If the handbrake is
pulled up when the caravan is moving in a backward direction the brake shoes shift into a reversing
position in the hub and release the brakes to approximately 60%. The caravan will continue in a
backward direction until the overrun brake lever shifts into an overrun position to activate the
brakes fully. This could take up to 1m. For this reason it is advisable to place chocks behind the
wheels before uncoupling on a downhill. When you are travelling and you apply brakes in your car,
the momentum of the caravan causes the caravans coupling to push back and apply the caravan
brakes. The shoes will shift into a forward position braking the caravan. When you are reversing your
combination the coupling will also push back and apply the caravan brakes, but because the caravan
in going in a backward direction the shoes will once again shift into a reversing position in the hub
enabling you to reverse without the brakes being applied fully.
Setting the Brakes
The below procedure should only be attempted by a qualified person.
The brake setting should be done by an approved OKTO dealer while the caravan is still under
warranty period. Before adjusting the brakes you need to roll the caravan in a forward direction and
apply the handbrake until the caravan stops. This will ensure that the brake shoes are in the correct
position for adjusting.
Procedure is as follows:
•Make sure that the caravan is parked on a level area, preferably not on grass or soil,
then jack the caravan up so that both wheels are off the ground.
•Pull on the coupling head so that the coupling shaft is extended.
•Push the handbrake into a down position.
•Loosen all the lock nuts and release the tension of the centre rod and the brake cables
at the centre equalizer bracket by loosening the adjustment nuts.

•Remove the green dust plug in the adjusting hole at the rear of the brake drum. It is
situated in the backing plate of the hub assembly.
•Put a small flat screwdriver through the adjusting hole and click the adjusting nut while
you are rotation the wheel in a forward direction.
•Click the adjusting nut until the wheel stops turning.
•Then click the adjusting nut in the opposite direction until the wheel turns freely. This
should be approximately 5 clicks.
•At the centre equalizer bracket, take up the slack on the brake cables and centre rod by
adjusting the adjusting nuts and make sure the equalizer bracket is straight once done.
•Pull the centre rod away from the coupling and check that there is 5mm play between
the centre rod adjusting nut and the equalizer bracket.
•Now lock the all the lock nuts for the brake cables and centre rod.
•Make sure that the centre rod support bracket at the front of the caravan is not bent
and the cable can move freely.

It is advisable to take you caravan for a road test after adjusting the brakes.
Male sure that the wheel nuts are torqued to 95N.m and the tyre are inflated to 2.6 Bar.
On the road test evaluate the following:
•The caravan brakes equally on both wheels. You will notice a side-ways pull if the brake
unevenly.
•The caravan does not sway excessively.
•The caravan does not bump up hard against the car when braking.
•The coupling does not knock excessively when pulling away.
•The brake drums will get hot when braking in town. Take the caravan on a 5km road
where no braking is required and check that brake drums cool down.
THE ELECTRICAL SYSTEM
Brief description
The OKTO caravan is fitted with a 220volt and 12volt system. The 220volt supplies a Vectron Smart
charger, microwave and all the 220volt plug sockets. The charger monitors and keeps the
105 amp/hour battery in a fully charged state. The battery supplies the fridge, water pump and all
the interior and exterior LED Lights.

The Power Supply, Fuses and Switches
Above is a picture of the power supply unit which is located under the rear off-side dinette bunk.
The Power Supply Unit (PSU) is designed to be as user friendly and as robust as possible. The 220v is
channelled through an Earth leakage and circuit breaker. The PSU also distributes the 12v to the
various circuits, namely the LED lights, water pump, fridge and the exterior auxiliary cigarette lighter
socket and USB ports. The circuits are protected by inline blade fuses locate in a fuse box on the PSU.
Below is a table indicating the fuse circuit and correct amperage. The Fridge and water pump also
have their own circuit breakers as indicated in the picture above.
In addition to this fuse box OKTO have fitted a 30amp Mini High Current Bolts Fuse. This is located
behind the PSU and is accessible from the rear baggage compartment. It is a

The Vectron Charger has blue tooth and can be linked to Smart devices such as Cell phones and
tablets. The App is available on Play Store and is called VictronConnect. Once the app is installed
onto your device the app will prompt you for a password, which is “000000”. The app will show you
the condition of the battery, the Voltage available, the Amperage being use by caravan and more.
Interior Lights
All the interior lights are LED lights and designed to draw as little current from the battery as
possible without sacrificing comfort. The furniture LED lights are neatly hidden away and will
provide light into the caravan living space when the doors are closed as well as into the lockers and
cupboards when the doors are open.

Owners Handbook

The lights are controlled from a central panel located on the cupboard to the left as you enter the
caravan. In this panel there is a voltmeter that indicates how much voltage is available in the battery
The reading and awning light have their own switches. The awing light will require you to switch on
the awning and step light switch at the control panel first.
If you are not plugged into 220v it is advisable to switch off lights that are not in use. This will give
you a longer battery life. Here is a simple calculation to help you determine how much battery life
you have once the battery is fully charged.
Battery is a 102 amp/hr Deep Cycle Leisure battery. Available amperage would be 75% of the battery
capacity, therefore you have 75 amp/hour available before you need to charge the battery up again.
Based on the equation for Power Watts = Amp/h x Voltage below is a table to help you determine
how much battery life you have left.

Battery and battery maintanance
Your OKTO caravan is fitted with a 12 volt Deep cycle Leisure battery with a capacity of
102amp/hours. The battery is a sealed Lead/Acid battery and does not require topping up with
distilled water.
Check that the battery terminal clamps are always correctly connected to the battery.
The positive clamp (red wire) needs to be clamped to the (+) post of the battery. The negative clamp
(black wire) needs to be clamped to the (-) post of the battery. Always connect the positive clamp
first. When disconnecting the battery terminals. Always make sure that the battery box lid is fitted.
It is advisable to keep the caravan plugged into 220v mains while the caravan is being stored.
The Vectron Smart charger will manage the battery and ensure that the battery is kept in a fully
charged state. If you cannot store the caravan with the mains connected then it is important to
disconnect the battery terminals from the battery.
The caravan battery should however be charged up at least once a month for four days.
The battery should never be allowed to discharge fully. In the discharged state the lead plates of the
battery build-up a calcium layer. This layer thickens with time and if left to long may cause
irreverasble damage to the battery in which case the battery may need replacing.

Road Lights
All OKTO caravans are fitted with LED tail, indicator and stop light. These LED lights require no
maintenance. The lights are all wired negative to earth and conform to SABS specifications.
Below is a diagram indicating the wiring of the 7-pin socket and plug.
OKTO does not use pin number 2 for the fridge, but instead your nearest OKTO dealers will be able
to fit a Brad Harris plug connection on your caravan, to charge up the battery while you are
travelling. The fridge can then be switched on to run from the caravan battery.
The Water Sytem
Your OKTO is fitted with a 12 volt submersible water pump which fits into the 25ltr water container
located in the front nose storage area. The water pump is activated by a micro-switch which is fitted
in the taps of the caravan. The fuse for the water pump in situated in the fuse box on the PSU and
has its own circuit beaker if you want to switch all the taps off.
It is recommended to travel and store the caravan, with the container empty, when possible.
Please do not let the water pump run when the water container is empty, this will cause damage to
the pump.
