Chapter 1: Introduction
Our motor homes are continuously being further developed
and for this reason we must reserve the right to make changes
to the equipment, shape and technology. Certain kinds of
accessories are also described in this user manual that are
not part of the standard scope of delivery. For this reason, no
claims may be asserted against HOBBY based on the conten-
ts of this user manual. Those accessories that are available at
the time of going to print are described here. They have been
applied on a par for all oor plans. Please note that it was
not possible to describe all of the individual variations here. If
you have any special questions concerning accessories or the
technology of the vehicle, your dealer will be happy to answer
them.

the accelerator stop valves for the consumer loads.
• Turn o the electric supply.
• Sound the alarm and call the re department.
• Only ght the re yourself if you can do so without risk.
Chapter 2: Safety
2.1 General information
• Operating and user instructions for built-in equipment (re-
frigerator, heating, cooker, etc.) as well as for the basic ve-
hicle must be observed at all times.
• If accessories or optional equipment is to be installed, this
may change the measurements, weight and road perfor-
mance of the engine home. Some accessories must be re-
gistred and entered in the vehicle's papers.
• Use only tyres and rims that have been approved for your
engine home. Information on tyre and rim sizes can be
found in the vehicle's registration document or in Chapter
14.4.
Warnings and information labels are attached both inside
and outside the vehicle. These are meant for your safety
and may not be removed.

Safety 02-2
2.3.1 Emergency equipment
To be prepared in case of an emergency, you should always
carry the three emergency devices on board and familiarize
yourself with them.
First-aid kit
The rst-aid kit should always be at hand and have a xed
position in your motor home. Any objects removed from the
rst-aid kit should be replaced immediately. Expiry dates should
be checked regularly.
Reective jacket*
In acc. with EN 471, we recommend that you carry and wear
a reective jacket with white retro-reective stripes whenever
you leave the vehicle on open roads and emergency strips.
The driver must put on this warning vest when the vehicle
• comes to a stop outside city limits on an obscure rural road
because of an accident or breakdown, if the view is poor
due to bad weather, in twilight or darkness, or
• when it must be secured by means of a warning triangle
on the emergency strip of the engineway because of an
accident or breakdown.
Warning triangle
The warning triangle should also always be at hand and have
a xed position in your motor home, preferably together with
the rst-aid kit.
In an emergency
• Set up the warning triangle at least 100 m in front of the
danger zone!

2.4.1 What to observe before taking your rst drive
Vehicle registration
Every vehicle that drives on public roads must be registered. This
also applies to your new engine home. Apply for registration at
your local Driver and Vehicle Licensing Agency.
You must show the following when applying for
registration:
- registration document, Part II / CoC
- insurance coverage
- proof of personal identity or conrmation of registration by a
local authority
- if applicable, power of attorney to register the vehicle
- If applicable, the direct debit authorisation for motor vehicle tax
General inspection
In common with passenger cars new engine homes with a per-
missible total weight up to 3.5 tonnes do not have to undergo a
general inspection for the rst three years after initial registration.
After this they must undergo a general inspection every two years.
Engine homes weighing between 3.5 and 7.5 tonnes must under-
go a general inspection every two years during the rst six years
following initial registration. After this a general inspection must
be carried out every year.
2.4 Before driving

Safety 02-4
The general inspection can be carried out by the German
Technical Surveyance Association (TÜV), the German Engine
Vehicle Surveyance Association (DEKRA) or an ocially appro-
ved expert.
Any changes made to the vehicle that underlie German
Road Traffic Licensing Regulations must be officially
authorised!
If you have any further questions or diculties, your autho-
rised Hobby dealer will always be available to assist you!
• Tighten the nuts on the wheels after driving the rst 50
km with your camper.
• Switch o the gas-operated built-in devices before put-
ting petrol in the tank.

Safety
02-5
2.4.2 Before each drive
Road safety
• Before driving, check that the signalling and lighting systems
(switch on battery circuit breaker), steering and brakes
function correctly.
• If the vehicle has been standing for a longer period of time
(approx. 10 months) have an authorised workshop check
the brake system and the accelerator system.
• Completely open and fasten the dimming system on the
front and side windows.
• In winter, the roof must be cleared of snow and ice before
driving.
• Regularly check the tyre pressure before driving. False tyre
pressure can cause excessive wear, damage to the tyres or
even lead to a burst tyre.
• Check liquids such as oil, coolant, brake uid and wind-
screen washer uid and top them up if necessary.
As the owner / driver of the vehicle, you are responsible for the
state of the vehicle. Please observe the following points:
Loading
The following applies for loading:
• Load evenly. Heavy or bulky objects should be placed in the
lower compartments!
• After loading, use a public weighing facility to check the total
weight and axle loads.

Safety 02-6
• The maximum permissible load for the rear external
storage locker is 150 kg.
• On no account should the permissible rear axle load be
exceeded.
• Due to load removal on the front axle, it is considerably
more dicult to handle the vehicle when the rear garage
is fully loaded.
Roof load (50 kg maximum)
The height of the motor home may vary from one journey to the
next due to dierent roof loads.
The following applies for roof loads:
• Add the measurement of the roof load to the height of the
motor home.
• Place a not visibly in the driver's cab giving the overall height.
This saves having to calculate the height when driving under
bridges and through tunnels.
Rear garage (model-specic)
When loading the rear garage adhere to the permissible axle
loads and the technically permissible total mass. Distribute pay-
load evenly. Excess point loads will damage the oor covering.
• Fully charge the batteries before each journey. Please refer
to the section on "Ancillary battery".
• Switch on battery circuit breaker.
Battery
Driver‘s cabin
Do not forget the following:
• Adjust the interior and exterior mirrors as well as your seat.
Preparing the vehicle
Check the exterior of the vehicle and carry out the following
preparations before driving:
Preparing the vehicle
• If the levelling supports* have been extended, retract
them.
• Close all the windows in the engine home as well as sky-
lights in the roof.
• Retract the entrance step.
• Close the tap for the waste water tank.
• Close all of the gas stop valves on the gas devices, with
the exception of the stop valve for the heating if the vehi-
cle has been equipped with a gas pressure regulator for
use while driving. (e.g. Control CS, SecuMotion)

Safety
02-7
• If necessary remove the 230 V electric cable from the exte-
rior socket.
• If necessary, slide the TV antenna* in as far as possible or
retract the satellite dish*
.
• If necessary secure any loads on the roof ensuring that
they cannot slide.
• If necessary secure bicycles; ensure that they cannot slide
and check that the existing lighting systems are not
covered.
• If necessary turn o the light in the tent in front of the
engine home.
• Should there be a rear ladder, fold and secure it.
Interior
Some preparations must also be carried out inside the motor
home.
Preparing the interior
• Sort loose objects and stow them in the compartments.
• Place heavy objects in the lower compartments.
• If necessary switch the refrigerator to 12 V operation.
• Ensure that no liquids, including those in the refrigerator,
will leak.
• Secure accelerator cylinders.
• Fold down and secure the table.
• Turn o interior lights.
• Secure the table and, if possible, lower it.
• Close doors (including refrigerator door), drawers and
aps rmly.
• Heavy and/or voluminous objects (e.g. TV, radio) must be
secured before driving.
• Fully open the darkening system for the driver's cab and
lock it into place.
• Push the washroom with sliding elements (model-specic)
to its original position.
Place a note with all important measures and weights in
a visible place in both the caravan and the driver‘s cabin.
Do not overload the vehicle! It is imperative that you not the
permissible axle loads, the technically permissible overall
mass as well as the permissible height, width and length
of the motor home.
Gas bottles may only be transported when they are secu-
rely fastened in the gas bottle container provided.
Ensure that there is sucient ventilation. Never cover up
built-in forced ventilation (skylights with forced ventilation
or mushroom vents). Ensure that forced ventilation is not
covered by snow or leaves as this increases the danger
of suocation.

Safety 02-8
2.5 While driving
Your motor home is not an automobile!
In many situations, it reacts very dierently to a “normal“ au-
tomobile. Therefore, you should be prepared for the following
dierences:
Passenger safety
The following applies while driving:
• Only those seats equipped with safety belts may be used
by passengers.
• People may not be lying in the beds while driving.
• Passengers must remain in their seats with their seat belt on!
• Only install children's car seats on seats that have been
tted by the manufacturer with three-point belts.
• Turn the swivel seats in the direction of trac and lock
them into place. The seats may not be turned while driving.
• Lock the sliding seat* into its original position.
• Do not open the door latch!
• No extra passengers may remain in the vehicle!
Driving
Take a trial drive before leaving on your rst large journey in
order to familiarize yourself with the motor home. Remember
to practise reversing. The base vehicle is a commercial vehicle;
adjust your driving style accordingly.
The following applies for driving:
• Do not underestimate the length of the engine home. Due
to the relatively long rear overhang larger vehicles can
veer to one side and, in unfavourable conditions, the rear
can hit the ground.
• Be careful when driving into inner courtyards and through
entrance gates.
• The motor home may start to swing from side to side in
cross-winds, on wet or icy roads.
• Adjust your speed to road and trac conditions.

Safety
02-9
• Long descents with a slight gradient can become dangerous.
Adjust your speed from the very beginning to allow you to
speed up if necessary without endangering other automobiles.
• As a general rule, never drive faster downhill than uphill.
• The motor home may be caught up in a slipstream when
overtaking or being overtaken by lorries with trailers or buses.
This eect is counteracted by lightly counter-steering.
• Use foresight while driving; take regular breaks on longer
drives.
Driving arround corners
Due to its height, a motor home begins to sway more quickly
than an automobile.
The following applies for driving arround corners:
• Never drive too quickly into a corner!
Driving economically
The engine of your motor home has not been designed to drive
constantly under a full load.
The following applies when driving:
• Do not keep your foot down on the accelerator!
• The nal 20 km/h before reaching top speed require up to
50 % more fuel!
Getting petrol
A number of devices that use an open ame have been built
into your motor home.
The following applies when getting petrol:
• Turn o all accelerator devices (heating, refrigerator, etc.)!
• Turn o all mobile phones!
• Never get anything other than diesel fuel.
• Never mistakenly ll the fresh water tank with fuel.
Braking
The following applies for braking:
• Not the longer braking distance, especially on wet roads.
• When driving downhill, select a gear that is not higher than
when driving uphill.
Reversing/Manoeuvring
Your engine home is far larger than a car.
The following applies to reversing/manoeuvring
• Even if the wing mirrors are correctly adjusted there is a
signicant blind spot.
• When reversing or parking in places with poor visibility get
help to guide you in.

Safety 02-10
2.6 After driving
Selecting a parking space
The following applies for selecting a parking space:
• Select a parking space that is as level as possible.
• If possible, pick your spot in daylight.
Securing the vehicle
The following applies when securing the vehicle:
• Put the vehicle in gear.
• Pull on the handbrake.
• If necessary, extend extra vehicle supports.
• If necessary, use blocks (not in scope of delivery).
If the temperature is below 0°C only put the handbrake
on lightly and ensure that the vehicle is in gear to prevent
the handbrake from freezing up!
When turning the driver‘ seat, ensure that you do not acci-
dently disengage the handbrake.
Switching electric consumption:
The following applies when switching electric consump-
tion:
• Switch the refrigerator from 12 V to accelerator or 230 V.
Otherwise, if the engine is not on, the 12 V electrical supply
will automatically turn itself o after a few minutes.
• Open the main stop valve on the accelerator cylinder and
the accelerator stop valve on the consumer required.
Water installation
Water left standing in the fresh water tank or the pipes quickly
becomes undrinkable.
Therefore, check the water pipes and the fresh water tank
before each drive to ensure they are clean. Disinfect and rinse
the drinking water
facility regularly, and always before each journey.
Please empty any residual water from the water tank
before lling it with fresh water.

Chassis
Chapter 3: Chassis
3.1 Chassis
The chassis includes parts of the frame and the axles. No
technical changes may be made, as otherwise the general type
approval will expire!
Technical changes may only be carried out after being
released by the manufacturer.
For further information, please refer to the enclosed ope-
rating instructions for the basic vehicle.
03-1
3.2 Vehicle identication number (VIN)
The 17-digit vehicle ID number has been applied to the inner
wheel case on the passenger's side.
To identify it more easily, the VIN on Fiat models can also
be found on a label on the left-hand side of the dashboard,
which is legible from outside the vehicle. In addition, the VIN
is also given on the type plate of the base vehicle as well as
on the Hobby type plate (in the motor compartment on the
upper front cross member of the radiator).
Always have your VIN at hand whenever you have a question
or visit your dealer/contractual partner.

Chassis
3.3 Loading
The maximum axle loads as well as the technically permis-
sible overall mass entered in the vehicle‘s documents may
not be exceeded
3.3.1 General information
Rules for loading:
• Spread the load evenly between the left and right-hand
side of the caravan. Heavy or bulky objects belong in the
lower storage compartments and near the axle.
• Storebaggageintheinteriorincupboardsandstorage
compartments.
• Heavyobjectsshouldbestowedsecurelytoprevent
them from slipping.
• Lighterobjects(clothing)shouldbestowedinthewall
cupboards.
• Securedoorsandaps.
• Checkthetechnicallypermissiblemaximumweightand
theaxleload(s)afteryouhavenishedloading.
Overloading can cause the tyres to break down or even
burst! This increases the danger that you may lose control
of the vehicle. Therefore, you endanger yourself and other
road users.
If you are not sure whether or not you have overloaded the
vehicle, you should have it weighed at a public weighing
facility.
