MANUAL
We are delighted to be able to congratulate you on the purchase of your
CORVUS vehicle and we would like to thank you for the confidence you
have placed in us.
You are now the owner of a modern multi-purpose work vehicle that you will
enjoy a lot if you care for it and maintain it adequately. Before you start it
up for the first time, please read the instructions of use carefully to become
familiar with the handling and the characteristics of your vehicle. Only in this
way will you be able to understand how to best adapt your vehicle to your
requirements and how to avoid accidents. For your safety we recommend
that you use only spare parts and accessories authorized by CORVUS.
If you use any other products, CORVUS declines all liability for any damages
that may arise from so doing. We recommend you follow the instructions on
the driving-in period and maintenance intervals in order to prolong the life
of your vehicle. For maintenance work, you should always consult an ocial
CORVUS distributor or dealer.
Driving in the countryside is fascinating and we hope you will enjoy it
to the full. Although CORVUS vehicles are environmentally friendly,
environmental problems and conflict with other people may ensue in the
countryside. Handling the vehicle in a responsible way ensures that these
problems and conflicts do not arise. Be sure to use the vehicle within the
bounds of the law, show that you are environmentally aware and respect
the rights of others.
#ExploringYourWorld
In the interest of technical development, CORVUS INNOVA S.L. reserves
the right to modify the construction, equipment and accessories of its
vehicles without notice. Size, weight and power data should be understood
with the respective tolerances. Depending on the volume of your CORVUS'
equipment and accessories, and on the versions that are approved in
compliance with the dierent laws of each State, there may be variations
with regard to descriptions and illustrations. The photographs in this
manual may not therefore correspond to the model you have purchased.
For this reason, no liability can be derived from any error, printing error or
omission.
In the event of any discrepancy or question about the content of this
manual, we recommend that you contact our After-sales Service.
YOU SHOULD READ THIS MANUAL CAREFULLY AND COMPLETELY

Cautions and warnings

MANUAL
WARNING
Take proper precautions while driving, especially in turning manoeuvres;
driving on slopes or in areas with obstacles can cause a collision or make
the vehicle overturn.
Only people who have a driving license should drive this vehicle. It is
advisable that the driver and their companion should use a helmet and
goggles when using the vehicle. Do not cause the vehicle to jump or flip, be
aware of changes in the terrain on which you are going to drive.
Check the possible obstacles that you want to clear, do not attempt to clear
major obstacles, such as fallen trees, rocks, slopes, muddy areas, etc.
Take care in slippery areas, drive at low speed, watch out for any possible
loss of grip, do not tackle steep slopes.
DANGER
You should not use the vehicle in a way that is not in line with the criteria and
instructions contained in this manual or in a way that may cause damage
to persons or things.
These are some examples of unsafe use and misuse:
• Driving with more than two people in the vehicle.
• Not keeping the entire body inside the cabin.
• Transporting people in the cargo box.
• Not complying with the instructions for use and maintenance set forth in
this manual.
• Exceeding the cargo and towing limits.
• Driving on unstable or not consolidated ground.
• Driving on terrain with an inclination of more than 15%.
• Driving in flooded areas (maximum temporary fording depth is 40 cm).
• Using accessories, parts or equipment that are not authorised by
CORVUS.
Adapt the speed of the vehicle to the terrain. When driving downhill, use
the short LOW gear and keep the speed as low as possible, gently applying
the brakes without locking the wheels. Under no circumstances should you
perform manoeuvres with a slope / elevation or lowering greater than 15%.
If you need to tow your vehicle, make sure the towing vehicle has sucient
drag and braking capacity, use a tow bar or a suciently long cable and do
not go any faster than 10 km/hr.
All technical and mechanical repairs must be carried out by an authorised
CORVUS garage.
Do not use the vehicle nor leave the engine running in enclosed premises
if they are not suciently ventilated, a concentration of exhaust gas can
cause death.
DANGER
The exhaust pipe and other elements reach high temperatures during use
and take time to cool down after you turn o the engine. Avoid handling or
touching anything during this period.
DANGER
Avoid using loose clothing that could get caught up with parts of the
vehicle or the environment. Although total security is impossible, the use
of adequate equipment reduces the likelihood and/or severity of injuries.

CLIMATE CONTROL SYSTEM
CLIMATE DIFFUSERS
The air distribution cannot be changed at the
climate control system's diusers; the only
way to increase the flow of air at the front
window (B) is by closing the outlets (A).
The climate control system improves
visibility and helps to prevent the front
window from fogging up. It is therefore
important that you are familiar with
the correct operation of the climate
control system.
The climate control console is located in the
lower centre of the instrument panel.
You can control the air temperature and the
blower speed and you can switch on the air
conditioning by means of the console.
- (1) Air outlet temperature control.
- (2) Air conditioning ON/OFF.
- (3) Blower speed control, for air outlets (A
and B).
Running without the air conditioning.
When the air conditioning button is switched o, it is not possible to obtain air at a lower temperature than
the ambient temperature. The selector knob (1) will change the temperature from cool air to warm air.
Running with the air conditioning.
The air will come out cooler than the ambient temperature; the minimum temperature will be factory set.
Use the temperature selector (1) to set this temperature.Turn it to the left to set the minimum temperature
and to the right to set the maximum temperature.
Do not handle the refrigerant gas contained in the circuit.
If the air conditioning unit does not work properly, please contact Corvus service.

HEATING SYSTEM
CLIMATE DIFFUSERS
Use the selector switch (1) to change
the air distribution at the diusers of the
heating system. By turning the selector
switch clockwise, an electrically controlled
valve will open to allow more air flow to the
diusers (B) at the front window.
The heating system improves visibility
and helps to prevent the front window
from fogging up. It is therefore
important that you are familiar with
the correct operation of the heating
system.
The heating selector switches are located
in the lower centre of the instrument panel.
Their functions are as follows:
- Selector (1) of the output air flow in the
diusers of the front windscreen (B).
- Selector (2) of the output air flow.
- Selector (3) of the output air flow
temperature.
The temperature selector (3) does not allow you to obtain a temperature lower than the ambient
temperature. To obtain more calorific power, the engine must be at operating temperature.
If the heating unit does not work properly, please contact Corvus service.
The heater can only work when the engine is running.
