4. DOCUMENT STRUCTURE AND SIGNS ADOPTED
This manual describes and explains the aspects necessary for the correct use, perfect maintenance in operation of
the of the underwater SCOOTER VRX - VRT.
The manual is divided into different sections, each one dedicated to a single topic.
Each section, if necessary, contains respective subsections, dedicate to the description of all the details needed to
the correct understanding of the operations and the actions to be carried out.
When useful, drawings or diagrams are shown for illustrative purposes to allow for the correct identification of parts
and the actions to be performed.
Pay special attention to the hazard signs in this manual. Warning signs that are placed next to a paragraph indicate
respectively:
DANGER!
This signal warns that failure to comply with what is described exposes the user
to risks that could cause damage to health, serious injury or even death.
5. DESCRIPTION AND OPERATING PRINCIPLE
5.1. OPERATING PRINCIPLE
The underwater SCOOTER (VR- X 71419 and VR- T 71420) consists of a perfectly hermetic hollow body, with a
hydrodynamic shape, (fig. 1), inside which the electric motor, the rechargeable batteries and the speed reducer
necessary to move a propeller that provides a propulsive thrust.
5.2. PARTS DESCRIPTION
On the front there is a handle (4 - Fig.1) which is used for gripping and lifting the SCOOTER and the nosecone (8)
whose opening gives access to the battery compartment. The opening of the nosecone is possible by turning the
closing handwheel (9) counterclockwise.
The cap (6A) are located posteriorly, which has the function of protecting the charging connector. The charging
connector allows the battery to be recharged from the outside without removing it (only with the use of LI ION
batteries), see chapter "Battery charging".
In the rear portion, there is a maneuvering handle (1), where the trigger (2) is integrated which, by controlling a metal
lever (3), allows the control of the rotation of the propeller. The propeller (10) is located at the rear end which, by
turning, generates the propulsion thrust, the latter being protected by a radial circular band which constitutes the flow
conveyor (5). Always at the rear there are the main switch (6) which disconnects the power supply and the speed
adjustment knob (7).
WARNING!
This signal warns that failure to comply with what is described exposes the user
to risks that do not normally lead to damage or injury.
CAUTION!
This signal warns that failure to comply with what is described exposes the user
to risks that could cause permanent damage to the vehicle.

6.2. PRODUCT IDENTIFICATION
The DPV is uniquely identified by the serial number engraved at the back of SCOOTER.
The battery has a serial number and the certification code engraved on the battery top lid.
These numbers are to be quoted whenever technical assistance or spare parts are required.
7. INTENDED USE
The SCOOTER manufactured by SUEX s.r.l. has been designed and built for towing a diver underwater. The diver
is assumed as being part of an army and be professionally trained to the diving practice.
The SCOOTER has been designed, sized and manufactured for the sole purpose
described above. Any other use has to be considered inappropriate and potentially
DANGEROUS.
The SCOOTER has been designed, sized and manufactured for the sole purpose
described above. Any other use or operation that does not comply with the
instructions contained in this manual, may damage the SCOOTER. This would
prevent the conditions for which it has been designed and built from being
achieved, and may compromise its technical and safety characteristics.
The manufacturer shall not be liable for damage to persons and/or objects deriving
from inappropriate use of the vehicle.
The SCOOTER IS NOT A LIFE-SAVING DEVICE: the diver must always plan the
dive in full safety conditions, without relying on the SCOOTER functioning support
for surviving.
Any ALTERATION that may substantially modify the SCOOTER functioning or
intended purpose:
- is forbitten
- is potentially dangerous
- is ground for exclusion from the warranty.
SUEX non risponde per danni a persone e/o cose derivanti da uso non conforme.

8. SAFETY INFORMATION
8.1. SIGNALING PLATE
The following label is glued on the SCOOTER, it must never be removed and in case of illegibility it must be replaced
with a new one to be requested from SUEX assistance. The removal of this label implies the non-responsibility of
SUEX s.r.l. for accidents occurring as a result of conduct held in contravention of the indications contained therein.
8.2. TRAINING
To use the SCOOTER the diver must have obtained the necessary certification from qualified agencies.
A lot of information is also available to the kind customers on the site: www.suex.it.
8.3. EQUIPMENT CONFIGURATION, TRIM AND RIDING POSITION
The SUEX SCOOTERS are of the TOW BEHIND type: ideal use requires that the diver be towed while remaining
behind the SCOOTER.
The SCOOTER should not be improperly connected to the diver.
The diver must be adequately trained to face and manage his dive safely even in the event of a SCOOTER failure.
The user must be able to leave the SCOOTER at any time and with extreme ease.
The diver must always carry a cutting device with him in the event that it is necessary to cut the tow cable that may
be used.
PROPER WAYS TO CONNECT THE DPV TO THE DIVER: HARNESS AND TOW CORD
The SCOOTER must be connected to the diver via a cable and a quick release carabiner.
Use the correct towing harness (see SUEX accessories) and the two cords provided.
Connect the carabiner to the front D-ring of the harness.
CORRECT WAY TO CONNECT THE TOW CORD TO THE SCOOTER
The tow cord must be connected to the SCOOTER on the two holes near the handle on the propeller conveyor, see
the following images.

Rope fastening to the left
handle
Fixing to the right handle, with
adjustable knot.
DIVER POSITION
The figure above shows a diver in a technical configuration with a correct position of the SCOOTER with respect to
the person. Different positions would reduce efficiency in advancement.
For good traction efficiency the length of the tow rope must be adjusted taking into account the build of the diver: it
is very important to be able to obtain the position shown above.
Users have to make sure that the equipment (hoses, regulators, pony bottles,
pressure gauges, audible alarms, flashlights and pertinent cables, reels, etc) do
not dangle and cannot get into contact with the propeller and get entangled
creating serious hazard situations.

Rev. 05 –03/02/2021
Pag. 10/37
Code: 71419 - 71420
WRONG WAYS TO CONNECT THE SCOOTER TO THE DIVER
These include cords with knots, chains and elastic cords, to name a few, that do
not allow the SCOOTER to be immediately abandoned in the event of emergency!
They are forbidden and to be considered potentially dangerous!
9. PRELIMINARY OPERATIONS
The following operations must be carried out after a complete and careful reading of the instruction manual by
adequately trained personnel.
Upon receipt of the SCOOTER after checking the integrity of the packaging and the contents of the package:
•Check that the SCOOTER is hermetically sealed: that there are no spaces between the various components;
•Proceed with charging the battery (see chapter "Battery");
•Insert the sea ballast in the case of immersion in salt water (see chapter: "Setting up the SCOOTER during
immersion").
9.1. SCOOTER START UP
Once the above mentioned preliminary operations are carried out;
•Submerge the SCOOTER
•Verify that the propeller is free from any obstructions;
•Turn the main switch to ON position (6 - Fig.1);
•Hold the SCOOTER (by the handle (1));
•Press the trigger (2), the SCOOTER starts to move;
•Releasing the trigger, the SCOOTER stops;
•The dive begins.
10. BATTERY
For more details, see the user manual relating to the battery which is an integral part of this document.
10.1. OPENING THE BATTERY COMPARTMENT
Put SCOOTER in vertical position on the shroud (5) on a flat surface.
Turn the front fastening knob (9) counter-clockwise. When rotating the knob the nosecone (8) (see fig. 1) starts to
lift. Continue rotating the knob until the nosecone detaches from the body.
10.2. EXTRACTING THE BATTERY
Once the nosecone has been removed, unscrew the knobs (11 - Fig.2 - 3), disconnect the connector (15) and remove
the battery (14) by pulling it upwards.
Fig.2
Correct equipment configuration is a key factor for the safe diving in general and
it becomes vital when diving with the SCOOTER. As a rule, the type and position
of the diving equipment should guarantee perfect streamlining and no elements
should protrude or be left dangling.
