signs:
This sign warns that, if the described operations are not correctly
performed, the user may be subject to risks that could cause health
problems, serious injury or even death.
This sign warns that, if the described operations are not correctly
performed, the user is subject to possible risks that do not, however,
cause damages or injuries.
This sign warns that, if the described operations are not correctly
performed, the vehicle may be subject to damages.
Carefully read the instructions in this manual before using the vehicle.
2 Hazard warning
READ CAREFULLY
CAREFULLY READ THE BATTERY CHARGE AND USE INSTRUCTION
MANUAL, INCLUDING SECTION “BATTERY CHARGE”.
The underwater scooter 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 scooter 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 supplier with our underwater scooters 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
scooter and supplied instruments.
This scooter is equipped with a “cut off” device whose purpose is to protect internal parts,
preventing use when residual battery power is too low. When this device is triggered,
the scooter, inevitably, shuts off.

6 Diving safety
6.1 Training
The ADV can be used for both recreational and technical divers. In both cases it is
assumed that divers have received necessary certification from qualified boards. In any
case, ADV use requires specific training that permits fully safe use, taking full
advantage of its potential. Do not forget that the greatest risk is mainly due to the
underwater environment where it is used.
6.2 Handling configuration and settings
The ADV is TOW BEHIND type (thus different from the so-called “ride on top” kind) and
thus ideal use requires the diver to be towed by the ADV by a tow cord (between the
scooter and diver) or by holding onto the specific handles.
Warning. Restricting the ADV to the diver in a way that is hard to untie,
even by other divers, is strictly prohibited. Quickly abandoning the ADV
at any time must be possible.
We highly suggest gloves (better if padded at least 3 mm thick) be worn
when using the ADV. They prevent the diver from inserting fingers
between the propeller blades and protect him against the surrounding
environment.
Correct equipment settings are crucial to diving safety and become essential when
diving with the scooter. Generally, equipment types and positions must guarantee perfect
water dynamics and not protrude or hang from the scooter.
The diver’s position should tend to be horizontal during dives (settings and floating are
always the consequence of correct equipment settings and appropriate training) for safety,
autonomy, scooter speed and diving comfort purposes.
Pay the utmost attention when positioning equipment, especially
concerning: whips, valves, side tanks, pressure gauges, consoles,
sirens, flashlights and cables or reels, preventing them from hanging
and thus coming into contact with the propeller or accidentally catching
on the sea bed or companion, creating even seriously hazard situations.

Pag. 9
6.3 Hazardous area and residual risks
The propeller is protected by a flow conveyor and relevant supports. However, it is
exposed on both the suction and expulsion sides. Additional protections were not installed
in these areas since they would significantly reduce fluid passage in the conduit, drastically
reducing propulsion system performance.
Catching and cutting risk
Do not introduce any object or body part in the flow conveyor in contact
with rotating propeller blades. Except for the hand on the trigger, keep at
least 40 cm away from the propulsion group during use.
Above water, make sure the battery has been removed before touching the propeller.
Back-lumbar injury risk
Above water, use caution if the vehicle is manually lifted in incorrect
positions.
Crushing risk
When closing the hull, be careful not to place fingers between the two
parts.
6.4 Safety device
There is a torque limiter between the engine group and propeller. When the resistance
applied to the propeller exceeds a certain winding moment, it triggers preventing the
propeller from continuing to rotate.
The device emits a rhythmic noise that immediately warns its triggering. As soon as this
situation occurs, immediately release the trigger, turn off power using the main switch and
free the propeller from the foreign object.
Do not continuously run over 10 seconds. The torque limiter is
designed for emergency use and prolonged running could cause
damages.
If use conditions permit the foreign body to be removed from the propeller during the dive
in total safety, remove it. Otherwise, it is best to abandon the ADV and recover it later.

7 Handling and transport
In all transport situations, the scooter must always be fully closed.
The scooter was designed to be used in water environments, or underwater. When it must
be transported in loaded on a car, please take the following precautions given its shape
and weight:
- lift it holding a flow conduit support and front handle or, if preferred, only the front handle;
- during transport by car or boat, secure it so it does not move.
We recommend support code 90011 (see Suex accessories).
On a boat, never place it at the bow or in a place where it is subject to jolts. This could
damage internal parts. When placing the scooter on the ground, always use delicacy and,
when vertically positioned, rest it on the propeller conveyor: be careful to rest it on a flat
surface and that nothing comes into contact with the propeller spinner.
If you prefer to hold the scooter by the handlebars, do so, but try not to move them too
much since they were not built to sustain excessive loads. Do not support ADV weight by
the handlebar only.
8 Description and operating principle
The ADV is made up of a perfectly watertight hollow body, with water dynamic shape, that
houses the electric engine, the speed reducer, the rechargeable batteries and the
electronic drive components. On the rear exterior are two handlebars (1), one with a builtin trigger (2) which, driven by a sensor in the hull, controls propeller rotation. At the front, a
handle recessed in the hull (3) is used for lifting and handling. The propeller is at the rear
end which, turning, generates propulsion drive. The latter is protected by a flow conveyor
(4). At the top is a main switch with the twin speed control(5) and the power and battery
low lights (6) can be seen transparent on the right.
The front shell (7) is located at the front and holds the battery compartment and closing
knob (8).
There are two holes (9) for the tow cord on the flow conveyor, near the handles.

9.1 Opening and closing the hull.
Simply use your two fingers to open and close the hull: using the knob at the front of the
scooter, rotate the hull clockwise to close and counter-clockwise to open. (the device is
patented).
Holding the front handle, keeping the scooter on the ground and resting a foot on the
propeller conveyor, pull upwards.
Carefully check that the closing OR gasket is inserted in its housing, clean and adequately
lubricated with VASELINE OIL. Check hull mouth cleaning. Use a clean cloth to eliminate
dust or sand. Insert the hull. Rotate the hand wheel clockwise until fully closed without
over-tightening.

KEEP FLAMES AWAY WHEN OPENING THE HULL: EXPLOSION
HAZARD!
10 Tying the scooter to the diver
The ADV 7 underwater scooter has two handles the diver can hold to be towed. However,
for the best use of this type of scooter, wear the supplied harness with tow cord equipped
with quick release carabineer (supplied).
The harness must be worn so that is does not generate hazards during diving (for
this reason we strongly suggest you take a course held by a certified board) and the
tow cord, secured to the scooter, must be connected to the quick release
carabineer.
NOTE: before each dive, check that the quick release carabineer is
in good working order. To do this, pull the tow cord taut between
the harness ring and scoot and pull on the white knob. The
carabineer should immediately open and detach.
Defective quick release could create hazardous situations.
11 Setting regulation
The ADV setting must be NEUTRAL, meaning neither negative (sunk) or positive
(floating). It should remain stable at the desired quota. The vehicle is supplied with neutral
settings for fresh water. A ballast is supplied to compensate the difference between fresh
and salt water use.
11.1 Positioning the ballast for salt water use
The salt water ballast is attached to the scooter body by the two threaded knobs. Unscrew
the threaded knobs and remove the ballast for scooter use in fresh water.
Always leave the knobs screwed into the scooter to prevent losing them.

TO ENSURE YOUR USER INFORMATION IS UP TO DATE PLEASE DOWNLOAD THE LATEST VERSION OF THIS MANUAL FROM WWW.SUEX.IT
Pag. 16
Carefully store the salt water ballast when not in use.
Once the settings are selected, fresh or salt water, try submerging the ADV (obviously
closed as per instruction manual).
The submerged vehicle should remain perfectly horizontal. If this is not the case, move
the battery along the support rod forward, if the front tends to float, or back if the front
tends to sink. To do this, after removing the battery, using the mechanical battery support
stop and retry.
12 Autonomy
Provided autonomy data is indicative and refer to use:
- With the vehicle in good working order
- In tempered environments
- Without current
- At average load (diver with single tank or double tank 12 + 12 lt)
- In perfect water dynamic settings
Generally, the time to cover the round trip route is calculated and an autonomy RESERVE
is set which varies according to the type of dive.
In any case, the dive MUST be planned to be able to return to the emersion point
without the help of the scooter
.
13 Red led on, battery low
When the red led, next to the blue one, turns on (the blue led stays on), this means that
the battery is low. About 10/15 minutes of autonomy remain at this point depending on the
temperature of use and battery wear conditions. At the end of this period, the scooter will
stop due to the cut-off device.

14 Precautions during scooter use
14.1 Scooter use in apnea
Using the scooter in apnea gives you an unique appreciation of the
water environment you’re visiting and extend the route you could
normally run. However, the fact of being able to easily reach significant
depths you are normally not used to could be hazardous, with all the
risks tied to diving beyond your abilities.
14.2 Descent speed
The underwater scooter permits high descent speed. AVOID use to increase it since this
increases problems tied to compensation and psycho-physical acclimatization.
14.3 Ascent speed
The ADV MUST NOT BE USED FOR VERTICAL ASCENT. Its use in
this sense could induce too fast an ascent and thus, POTENTIALLY
HAZARDOUS. Therefore, it is best to position it, where it does not
create an obstacle, AFTER TURNING IT OFF, TURNING THE MAIN
SWITCH TO OFF and ascending normally.
14.4 Depth
NEVER EXCEED MAXIMUM OPERATING DEPTH!!! In any case,
diving, especially at that depth, is an EXTREMELY HAZARDOUS
activity. INCORRECT ADV USE IN THESE ENVIRONMENTS
INCREASES DIVING RISKS.
14.5 Occluded environments
Diving in these environments is, by itself, EXTREMELY HAZARDOUS.
INCORRECT ADV USE IN OCCLUDED ENVIRONMENTS
INCREASES DIVING RISKS. For example: hitting valves, when moving
fast, could cause them to break with the relevant consequences.
DIVING IN THESE ENVIRONMENTS REQUIRES ADEQUATE
TRAINING COURSES HELD BY QUALIFIED BOARDS. Please note
that ADV autonomy and gas management should be planned so that
each team member had DOUBLE the required resources. A spare ADV
must also be used.
10416UK
TO ENSURE YOUR USER INFORMATION IS UP TO DATE PLEASE DOWNLOAD THE LATEST VERSION OF THIS MANUAL FROM WWW.SUEX.IT
Pag. 18
14.6 Muddy or murky environments
These are environments, occluded or not, where visibility may be
suddenly blinded due to the silt lifted when sediment is moved. Diving in
these environments is, in itself, EXTREMELY HAZARDOUS.
INCORRECT ADV USE IN MUDDY AND MURKY ENVIRONMENTS
COULD INCREASE DIVING RISKS.
THUS, THIS TYPE OF DIVING REQUIRES SUITABLE TRAINING
COURSES HELD BY QUALIFIED BOARDS.
For example: propeller movement facing the bed could lift a significant
amount of silt.
Accidentally starting the spare ADV being towed could create seriously
hazardous situations.
14.7 ADV flooding, sinking
This could occur especially due to improper use, incorrect closing or
inefficient maintenance.
In the event of flooding, the scooter will start to tilt downward and thus
sink. In the event of total flooding, the situation could become
POTENTIALLY HAZARDOUS since the ADV will start to SINK,
DRAGGING THE DIVER DOWN and therefore the vehicle MUST BE
IMMEDIATELY ABANDONED.
15 General precautions
- Do not keep the ADV exposed to sun, closed in a car in the sun or exposed to
excessive heat (max 50°C). It could overheating, deforming, and couplings may no
longer guarantee water tightness.
- Avoid collisions when diving.
- Do not use it as a stool.
- Do not stand on it.
- Do not have it used by children or untrained people.
- Do not transport it dismantled or open.
- Do not charge the batteries with a battery charger other than the one supplied.
- Do not attempt to stop the propeller with your hands.
- Do not block the starter trigger when the switch is turned to on.
- Do not throw it off a boat or the shore.
- Do not dismantle it.
- Do not run it dry above water. Seal gaskets could rapidly deteriorate due to
overheating.
- Battery connectors must never come into contact with water. This would rust the silver
contact lining.
- Do not short circuit the battery.
- Do not remove wires from the connector or invert polarity.
- Do not get internal ADV parts and batteries wet.

16 Cleaning and storage
After scooter use, it is best to rinse it with fresh water (even if this is not mandatory). More
resistant dirt can be cleaned using a neutral detergent. Before opening it, remove all salt
and sand residues.
Do not use solvents or hydrocarbons.
The scooter must be stored in a cool, dry and ventilated place, vertically with the front
facing up. The battery must be removed, charged and stored away from excessive
heat and cold. Be careful since accidental contact with metallic objects in the connector is
an easy cause of short circuit. The hull opening hand wheel must be loosened to avoid
permanent deformations. Store it covered, if possible, to keep it away from dust.
Important note: always remove the batteries after use.
17 Easy inspect (visual engine hull inspection)
You can inspect the engine hull interior through the window on the engine compartment
divider. This lets you check for any flooding following incorrect use.
This system lets you make sure the scooter is in good working order before each dive.
17.1 Water in the engine compartment
If you see water in the engine compartment, stop using the scooter immediately and send
it to a service centre for maintenance.
If slight condensation appears in the engine compartment, especially near the inspection
window, this may only be temporary and due to a sudden change in temperature. It should
disappear with scooter use.
Inform the service centre of any other situation that may not seem normal to receive
assistance.
