WARNING!
PL AS R AD TH FOLLOWING
THIS MANUAL CONTAINS IMPORTANT PR CAUTIONS, WARNINGS
AND INFORMATION. IT IS IMPORTANT THAT IT IS CAR FULLY AND
FULLY R AD B FOR USING TH UND RWAT R SCOOT R!
Observance of the instructions contained in this manual will allow you to carry out use,
transport and maintenance operations safely, while guaranteeing optimal vehicle operation
and reduced running costs. The company SUEX is not liable for damage resulting from
negligence on behalf of the user or from failure to observe these instructions .
SUEX, declares that:
• the SUEX diving vehicle (henceforth called “ADV”) shall be delivered to the buyer in
perfect working condition, complete with its use and maintenance manual;
• any person attempting to use the diving vehicle shall be deemed to have undergone
specific training in the use of similar diving vehicles and to have obtained the
necessary certification issued by a qualified agency;
• any person attempting to use the diving vehicle shall be deemed to have read the
use and maintenance manual provided, and hence the instructions contained
within, in particular:
- how to use the diving vehicle, with details regarding the diver’s correct
equipment configuration, the diver’s posture during use, the position that
must be maintained by the diving vehicle during the dive, and that the vehicle
must not be bound with systems hard to release to its user in any way
whatsoever.
- the environmental conditions where use of the diving vehicle is especially
dangerous, such as deep-water dives, obstructed environments, muddy or
suspension-filled environments; the special precautions to be adopted when
dives are effected in such environments and the need of having undergone
suitable training held by qualified agencies;
- dangerous behaviour that is to be avoided such as, for example, use of the
diving vehicle to accelerate the descent or ascent rate;
• it is therefore assumed that the user has been fully informed on how to use and
maintain the product as well as of its technical characteristics, and that he shall
scrupulously abide by these rules.
• It hence follows that any damage to persons or objects, deriving from incorrect
maintenance of the diving vehicle or from its use other than as stipulated by this
manual or without the precautions described within, cannot be attributed to defects
of the product.
The company SUEX is not liable for losses or damages suffered by third persons
consequent to the use of this diving vehicle.

The ADV is not a toy, nor a suitable rescue means. It’s exclusive function is to help
expert divers in immersions to cover greater distances than could be normally covered
with fins only. The ADV and its components, specifically the battery and battery charger,
are intended for adult and expert use after carefully reading these instructions.
In order to prevent any harm to things or individuals, the user of the battery and battery
charger supplied with our diving vehicles must first read the use and maintenance manual
and strictly observe the indications on correct use and product features, preventing
inexpert personnel or minors from handling, even inadvertently, the ADV and
supplied instruments.
Our ADV are equipped with a “cut off” device that protects internal components, impeding
operations when voltage is too low. When this device is triggered, it inevitably, shuts
off.
This feature must always be kept in mind to avoid any hazards for the diver who, when
planning a dive, will leave sufficient time to surface even without ADV power should the
battery, due to the amount of time under water, die.
SUEX is not liable for any damages to persons and/or property caused by use other than
that described in this manual and in neglect of the precautions described herein.
Due to constant technological developments, SUEX diving vehicles may be modified at
any time without prior notice.
This manual is not a substitute manual for an adequate course held by certified
agencies on the correct use of ADV on dives.
Use of the ADV under the influence of alcohol and drugs and in any situation in
which psycho-physical conditions are not suited for diving is prohibited.
ADDITIONAL NOT !
If there are the following accessories, carefully follow the safety rules
N-Handle
Prop lock propeller
In addition to normal ADV use, these accessories make
it extremely important that you are fully aware of their
use and operations and the potential hazards that may
be associated with their use if not adequately informed
on their use. (see specific paragraphs)

2 D SCRIPTION AND OP RATING PRINCIPL S
The ADV consists of a perfectly watertight, streamlined, hollow body, see figure 1, inside
which the electric motor, rechargeable batteries and speed-reduction gear are housed. On
the outside, two manoeuvring handles (1) are found at the rear, one of which has an
integrated trigger (2) to control propeller rotation by means of a magnetic reed switch (3).
At the front, a handle in synthetic material ( ) is used for gripping and carrying the vehicle.
The propeller (10) is located at the rear end and is protected by a surrounding circular strip
which constitutes the flow conveyor (5). The main switch (6) for turning the power on and
off and the speed regulator knob (7) are also found at the rear.
In front is situated the head cap (8), by opening it we can access to the battery
compartment, the locking wheel (9) is inserted in the shell.
