You are now the owner of a modern multi-purpose work vehicle that you
will oer much enjoyment 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.

CAUTIONS AND WARNINGS

7We reserve the right to modify the product and the design. USER
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%.
• Do not drive through flooded areas (the maximum
temporary wading 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 downward slope 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/h.
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 any elements 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.
