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 NOTE!
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)

ESCRIPTION AND OPERATING PRINCIPLES
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 (4) 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.

5 C
ORRECT USE (SEE FIG.
1)
Check the preliminary operations. Proceed as follows to start the ADV:
Always make sure the switch (6) is in the off position, submerge the ADV under water and
make sure nothing is caught between the propeller blades. If something is found between
the propeller blades, remove the ADV from the water and free the propeller blades of the
foreign object. Be extremely carefully since using hands or other parts of the body
between the propeller blades is potentially hazardous, even if a safety clutch is
installed between the propeller and engine. For this reason, avoid introducing your
hands in the propeller area and, if necessary for cleaning purposes or to remove
foreign objects, use or stick or other suitable tool.
Turn the switch (6) (see fig. 1) fully clockwise without forcing it.
Grasp the two ADV handles (1) (fig. 1) or, if using the tow cord, hook the carabineer to the
tow sling.
Press the trigger (2) until the engine starts.
To stop the engine, let go of the trigger (2).
To change propeller rpm, use the knob (7), rotate it clockwise to drive the ADV slowly,
rotate it counter-clockwise to drive the ADV faster. This latter operation can be conducted
at any time, even underwater.
When finished use, turn the switch (6) counter-clockwise to turn off the ADV.
IF YOU DO NOT USE THE TOW CORD, DO NOT DRIVE THE ADV SINGLE-HANDED.
YOU MAY RISK LOSING CONTROL.
WARNING: when you press the trigger, the propeller starts to rotate and the ADV
starts to move.
6 B
ATTERY DEPLETED ALARM SIREN DEVICE
The ADV is equipped with an alarm siren system (continuous siren), easy to hear in both
immersion and emersion, which automatically sounds when a set voltage, considered the
minimum for ADV use, is reached, without further or inappropriately using the battery.
This alarm is always triggered, whether the ADV is in use or accidentally left “ON”.
When the siren sounds, the ADV may continue to run for several minutes. This amount of
time varies and depends on several factors such as the power used and battery wear
conditions. After this period, the battery cut-off will trigger, turning off the ADV. (see CUT
OFF paragraph)
Note: the sole purpose of the battery depleted signal is warn the diver that the
battery is low. SUEX is not liable for the failed operation or erroneous evaluation of
residual battery charge which led to the incorrect assessment of ADV autonomy.
The system is based on battery voltage readings that cannot fully guarantee
residual battery charge calculations. The indication highly depends on battery
wear.

DIVING SETTINGS
The ADV should have NEUTRAL buoyancy and be practically horizontal meaning it
should not sink but remain stable at the desired depth. The vehicle is supplied neutrally
buoyant or slightly float in fresh water. Additional weights (23), are provided to compensate
for differences between use in fresh or salt water (see fig. 7) consisting in a stainless steel
cilinders that should be included or removed according to whether the ADV is used in fresh
water (NOT USED) or seawater (USED).
Figure 7 (view of the ADV without the external case)
7.1 I
NSERTING THE BALLAST
Proceed as follows to insert the ballast (23): (see fig. 6)
Open the scooter and extract the battery (see previous chapters).
Insert the ballast on the rod (13) also inserting the anti-rotation pin (16) (Fig. 5).
Insert the battery and close the scooter as described in previous chapter, being careful to
connect the red connector if you have to use the ADV.
IMPORTANT NOTE: Figure 6 illustrates the ADV in fresh water settings, meaning the
green spacer (12) fig. 2 is positioned above the battery.
In salt water use, put the ballast in place of the green spacer.
7.2 S
ETTINGS AND TRIM ADJUSTMENTS
According to salinity or water temperature, you may need to adjust the float or trim settings
(trim is the ADV longitudinal axis inclination).
As for floating, the ADV is produced to slightly float in both fresh water (without using the
ballast 23) and salt water (using the ballast 23).
As for trim, you can change factory settings by moving the battery along the pin (13) fig.6.
Remove the battery, loosen the nut (21) with a 4 mm Allen key, unscrew or screw in the
ring nut (22); screwing it in, the ADV tends to position itself with the rear sinking,

NDICATOR LABEL
The following indicator label is found on the vehicle. It should not be removed, tampered
with or destroyed. The user of the vehicle shall be responsible for replacing any worn out
or illegible label with a new one, it must be requested to our after-sales service.

8.2 T
RAINING
The ADV may be used by any diver but it is assumed that whoever is effecting the dive
has obtained the necessary certification issued by qualified certification agencies. At any
rate, use of the ADV implies that the user has undergone specific training that
permits him to use the vehicle safely and to fully appreciate its potential. Do not forget that
the greatest danger is constituted by the underwater environment being explored.
8.3 E
QUIPMENT CONFIGURATION AND RIDING POSITION
SUEX S.r.l. diving vehicles are TOW BEHIND type (as opposed to a “ride-on-top” which
must be straddled) and ideally the diver should be towed behind the ADV.
READ CAREFULLY! The ADV should not be improperly bound to the diver. The user
should be able to abandon the ADV at all times and with extreme ease. The ADV must be
connected to the diver by a cord and quick-release carabineer. The diver should always
carry a sharp knife on dives to manage emergency situations including that of cutting the
cord and abandoning the vehicle.
Proper ways to connect the ADV to the diver.
The tow cord should be suitable dimensioned. Use of a 4 – 6 mm cord made of nondecaying synthetic material, in good working order and with at least 100 kg haulage
capacity is considered correct.
The carabineer must be made of rustproof material in good working conditions and
equipped with an easy to grasp opening device. It must also be usable with gloves. The
carabineer should be connected to the harness or “D” ring on technical balancing jackets.
Examples of the harness and bolt snap to be used

Improper ways to connect the ADV to the diver.
These include cords with knots, chains and elastic cords, to name a few, that do not allow
the vehicle to be immediately abandoned in the event of emergency!
Correct way to connect the tow cord to the scooter.
The tow cord should be connected to the ADV through the two holes near the handle on
the propeller conveyor. See the following illustrations.
Cord attachment to the left handle
10596
TO ENSURE YOUR USER INFORMATION IS UP TO DATE PLEASE DOWNLOAD THE LATEST VERSION OF THIS MANUAL FROM WWW.SUEX
Page 16 of 43
Attachment to the right handle, knot that allows for tow cord length adjustments.
Figure 8
Diver position Fig. 19 illustrates a driver in technical configuration with the ADV correctly
positioned. Other positions are admitted but considerably reduce drive efficiency. Tow cord
length is extremely important for good towing efficiency. The right arm should remain
slightly bent, drive the vehicle by pointing it in the direction to be followed but never hold
the ADV which exerts all drive force on the tow cord.
If you prefer not to use the tow cord, both handles must be used. This type of use does not
permit high speeds since resistance is higher with consequent arm fatigue.
The diver’s position during the dive must be more or less horizontal (posture and
buoyancy always derive from correct equipment configuration and adequate training). This
ensures safety, longer running times, speed and riding comfort.
Be especially careful when setting out your equipment especially as
regards: hoses, regulators, pony bottles, pressure gauges, audible
alarms, flashlights and pertinent cables, reels, etc., making sure they do
not dangle and that they cannot come into contact with the propeller or
entangle themselves on the bottom or on your buddy, creating
possibly serious hazard situations.
Correct equipment configuration is a crucial factor for safe diving in general and
becomes vital when diving with the ADV. As a rule, the type and position of the diving
equipment should guarantee perfect streamlining and no elements should protrude or be
left dangling.

SING THE
ADV
DIVING VEHICLE
Underwater diving is a potentially dangerous activity and incorrect use of the ADV further
increases the hazards of the dive itself.
Before use, make sure the battery is charged, that connectors are connected and that no
electrical parts are rusted. Check that the head cap is closed properly, check its condition,
especially following accidental bumps, or accidental scratches, and make sure that the
trigger and main switch are functioning correctly. At this point the ADV is ready for use.
After entering the water, the main switch must be switched on by rotating it.
The main switch must be turned to running mode only when the ADV is in
water. Rotating the propeller out of the water may be dangerous and
damage the seal of the motor shaft.
Once in the water, the propeller is activated by pulling the trigger
incorporated on the right manoeuvring handle towards you. Releasing the trigger will stop
propeller rotation.
Speed can be regulated slow or fast, see the previous paragraph fig. 7.
10 E
NTERING THE WATER WITH THE
ADV
Entering the water is one of the most delicate moments in the dive.
Various factors like the change in temperature, use of a respirator, the
weight of the equipment and other difficulties make the addition of the
ADV an inevitable added burden.
Before turning on or using the ADV, make sure that all the equipment
you use for the dive is correctly positioned and in good working order. Only use the ADV
after completing these checks. Incorrect dive preparation is highly dangerous and, in some
situations, the ADV may represent an additional hazard.
Pay particular attention when entering choppy water since waves could lift and launch the
ADV against you with even fatal consequences.
11 E
XITING THE WATER WITH THE
ADV
Exiting the water is another delicate moment in the dive and, here too,
the addition of the ADV could be an extra burden.
According to where you started the dive, always make sure the ADV is
the last piece of equipment to recovery. Always put your safety first.
Pay particular attention when exiting choppy water since waves could lift
and launch the ADV against you with even fatal consequences

12 “P
ARKING” THE
ADV
UNDERWATER
When diving you may need to “park” the ADV to continue the dive with
fins only, recovering the ADV later. We strongly recommend you leave
the ADV far from areas with currents that could cause the ADV to collide
with rock walls, the sea bottom or boats. Violent collisions could
compromise the ADV’s hermetic seal and irreparably damage it.
During decompression stops, be careful the ADV does not cause uncontrolled depth
variations, turning it off and leaving it at your side.
DO NOT USE THE ADV TO MAINTAIN THE DECOMPRESSION QUOTA!
.
13 D
ESCENT RATE
The ADV allows you to accomplish a fast descent rate. AVOID using it to accelerate your
descent since problems related to equalising and psychological/physical adjustment are
increased.
14 A
SCENT RATE
The ADV MUST NEVER BE USED FOR VERTICAL ASCENTS. In fact,
using it in such a manner may result in an excessively rapid ascent
WHICH IS POTENTIALLY DANGEROUS. Hence it is better to
DEACTIVATE IT BY TURNING THE MAIN SWITCH TO THE OFF
POSITION, position it out of the way, and ascend normally.
15 U
SING THE
ADV
IN APNEA
Diving in apnea is highly dangerous in itself. The use of the ADV in
apnea could cause serious accidents. Always be certain and aware of
your capabilities. Adequate training courses are essential for your
safety.

Page 19 of 43
16 D
EPTH AND OPERATING ENVIRONMENTS
DO NOT EXCEED THE MAXIMUM OPERATING DEPTH!!!
The dive is already VERY DANGEROUS at that depth. INCORRECT USE OF THE ADV
IN SUCH ENVIRONMENTS INCREASE DIVING HAZARDS.
It is important to remember that maximum diving vehicle operating depth refers to the ADV
in prime conditions. Collisions, scratches or deformations significantly reduce this limit.
16.1 O
BSTRUCTED ENVIRONMENTS
Dives in such environments are already VERY DANGEROUS.
INCORRECT USE OF THE ADV IN SUCH ENVIRONMENTS INCREASES THE DIVING
HAZARDS. For example: if the control valves are hit accidentally whilst travelling at high
speeds, these may break, with obvious consequences. DIVING IN SUCH
ENVIRONMENTS REQUIRES ADEQUATE TRAINING BY QUALIFIED AGENCIES. It is
hereby emphasized that the running time of both the ADV and the breathing gas must be
planned in such a manner that every team member has TWICE the necessary resources
available. It is also obligatory to carry another extra ADV.
16.2 M
UDDY OR SUSPENSION-FILLED ENVIRONMENTS
These include those environments, obstructed or otherwise, in which visibility may
suddenly fall to zero due to the suspension that is created by moving the bed sediment.
Dives in these environments are already VERY DANGEROUS. INCORRECT USE OF
THE ADV IN SUCH ENVIRONMENTS INCREASES THE DIVING HAZARDS.
DIVING IN SUCH ENVIRONMENTS REQUIRES ADEQUATE TRAINING BY QUALIFIED
AGENCIES.
For example: the rotating propeller that faces downwards can lift a considerable amount of
suspension.
Accidental activation of an emergency ADV in tow may create highly critical
situations.
17 P
OSITIONS AND BEHAVIOURS TO BE AVOIDED WHEN DIVING
The diver’s head or other body parts should never be beyond the
propeller conveyor (5) (see fig. 1) where flow is suctioned.
Do not direct the flow from the conveyor at you. This thwarts the
propulsion drive and could move your equipment away from you.
Do not ride the ADV.
Do not attach the ADV to your tanks or their supports in any way.
Do not attach the ADV to your body, legs, arms or other parts in any way.
Do not use more than one ADV simultaneously.

When using the ADV, always keep your left hand far from the propeller, better is resting
against your body, on your side, or on your right hand to more comfortably control the
ADV.
Do not direct propeller flow at the sea bottom to avoid raising sand or mud.
18 H
AZARDOUS AREA AND RESIDUAL RISKS
The propeller is protected by an external radial circular band. Therefore 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 and thus vehicle autonomy. A protection grill
on the flow suction side can be easily clogged when near aquatic plants or algae normally
suspended in the water, forcing the diver to frequently stop to clean the grill which is not
always possible in safety conditions underwater. A grill placed on the flow output side
would prevent any cords or lines caught in the propeller to be removed, inhibiting ADV
operations. This would frequently distract the diver and cause him to forget that the greater
hazard is represented by the surrounding environment and diverting the his main focus
away from the dive. For the above reasons and, considering that the propeller is protected
by a safety clutch, we believe that the natural behaviour of being careful not to place
hands or other body parts between propeller blades is safer for the diver (who in correct
use, is always behind the propeller) than being distracted by cleaning and untangling any
objects from the grills around the propeller.
Entanglement and cut hazards
Do not insert any object or body part inside the flow duct, that could
obstruct the rotating propeller blades. When in use, besides the hand on
the trigger, a safety distance of at least 40 cm must be maintained
between the diver’s body and the propeller assembly.
A CAP OR OTHER HAIR RESTRICTION DEVICE MUST BE WORN BY DIVERS WITH
LONG HAIR. LONG HAIR MAY BECOME ENTANGLE IN THE PROPELLER IN THE
EVENT OF IMPROPER USE.
ALSO BE CAREFUL OF ANY OBJECTS SUCH AS FISHING LINES, DIVING
EQUIPMENT, FLOATING TOYS OR ANYTHING ELSE THAT MAY COME NEAR THE
PROPELLER.
PROTECTIVE GLOVES MUST ALWAYS BE WORN
Crushing risk
Be careful not to place fingers between the two parts when closing the
maid body or head cap.
NEVER LEAVE THE ADV UNATTENDED ESPECIALLY NEAR
CHILDREN OR AMATEURS. ALWAYS TURN IT OFF BEFORE
EXITING THE WATER AND DISCONNECT THE BATTERY AS SOON
AS POSSIBLE (see previous chapters).

18.1 S
AFETY DEVICE
A torque-limiting device is installed between the motor and the propeller. When the
resistance felt by the propeller exceeds a certain torque, this device intervenes, preventing
the propeller from rotating.
The device will generate a rhythmic sound signalling its insertion. If this
situation occurs, release the trigger immediately, switch off the power by
means of the main switch and free the propeller of the foreign body.
Do not leave the torque-limiting device inserted for more than 10
seconds. It has been conceived for emergency purposes and may be
damaged by prolonged use.
If conditions allow you to remove the foreign body safely during the dive, then do so.
Otherwise let go of the ADV. Do not lubricate the safety device.

LECTRICAL AND MECHANICAL SAFETY SYSTEMSAPPLIEDTO
THE
ADV XJOY 37
In order to insure maximum diver safety when using the ADC, various solutions were
implemented to eliminate possible fault risks or potential injury.
19.1 E
LECTRONIC ENGINE CONTROL
The electronic engine control board includes:
A short circuit emergency fuse (on replaceable at authorized service centres)
Temperature sensor (slows propeller rotation to a stop. The system automatically restarts
when the engine is cool)
Maximum absorbed current sensor (maximum current that can be absorbed by the
electrical engine, fully automatic, to protect electronic parts)
Engine ignition sensor without mechanical contacts (the sensor is not a reed or
mechanical type but inductive)
19.2 E
LECTRONIC BATTERY CONTROL
The battery includes:
An emergency thermostat (if a battery charger fault occurs that overload the battery when
charging, the thermostat prevents battery overheating by cutting off the charge)
Cut off (in the event of depletion, it eliminates electric absorption cutting off the power
supply. It is restored when the battery is charged)
Overcharge. (If a battery charger fault occurs that overload the battery when charging).
Short circuits protection. Every cells has an electronic protection system against the
accidental short circuit, in any case DO NOT SHORT CIRCUIT THE BATTERY,
BECAUSE COULD BE DAMAGE THIS PROTECTION SYSTEM and the battery must be
replaced.

WITCH
This ADV comes with a switch the cuts off the battery from the electronic engine control.
Using the switch limits accidental ignition which may not occur in any case if the switch is
in the OFF position.
19.4 M
ECHANICAL CLUTCH ON THE PROPELLER
See chapter 18.1
19.5 T
RIGGER GUARD
The trigger is isolated by a guard that forces the diver to insert a finger in the ignition area
to press the trigger and start the ADV.
20 R
UNNING TIME
Running time data is indicative and is nevertheless referred to use:
- with a vehicle in perfect running order
- in moderate environments
- in the absence of currents
- with an average load (diver with a double tank 12+12 liters)
- in perfect buoyancy conditions
As a rule, the running time should be calculated to cover the descent and ascent. An
EMERGENCY running time, which will vary according to the type of dive, must also be
established.
In any case, when planning a dive you MUST consider the event of returning to the
exit point without the ADV.
21 S
PEED
Speed depends on the same factors as running time. The speed chosen should be
compatible with the type of dive and be adjusted to match that of your buddies.
22 P
RECAUTIONS FOR USE
- Do not expose the ADV to solar radiations, closed into the car under the sun, or
exposed to excessive heat (max 50°C). Overheating and successive deformation
may occur, to the prejudice of the water tightness of mating surfaces.
- Avoid bumps during the dive
- Do not direct the ADV toward other divers.
- Do not use it as a stool

ROUBLESHOOTING
PROBLEM POSSIBLE CAUSE - TREATMENT
The ADV does not run. When the trigger is activated
the propeller does not turn.
Open the ADV, check that the batteries are charged
and that the connectors are inserted and
undamaged, then try again.
Although the battery pack has been charged and the
connectors are inserted the ADV does not run.
The control system may be damaged - must be
checked.*
The motor may be damaged - must be replaced.*
The battery pack may be damaged - must be
replaced.
The speed regulator doesn’t work.
The control system may be damaged - must be
replaced.*
The ADV’s running time is visibly diminished. The batteries need to be replaced.
The battery charger is broken or does not work well -
must be replaced.
When the main switch is on, the ADV runs
continuously with no chance of stopping it.
The control card is damaged - must be replaced.*
The motor is noisy. The ADV needs to be serviced.*
Vibrations are felt when the propeller rotates.
The propeller is damaged - must be replaced.
The drive system is damaged - needs to be
serviced.*
The ADV floods very slowly.
Replace all the O-rings and carefully check that the
seating surfaces are not damaged.
The control trigger sticks and the ADV remains
running.
Shut off the ADV, try to slide the starting piston,
driven by the trigger, to get out any foreign bodies,
try to start again. If the ADV continues to work, the
starting system must be verified, probably it was
damaged by a shock.
There are oil stains on the conic end of the case near
the propeller or it is visibly greasy.
The external propeller shaft seal is damaged and
requires maintenance. The second internal seal
prevents flooding but you should suspend ADV use
and replace the gaskets.

FLOODING, SINKING
This could occur especially due to improper use, a collision, 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 YOU DOWN and therefore
the vehicle MUST BE IMMEDIATELY ABANDONED.
25 C
LEANING AND STORAGE
After use, the ADV must be rinsed thoroughly with fresh water. A neutral detergent may be
used for more stubborn dirt. Before opening the ADV, it is important to remove all traces of
salt. In particular, the magnetic reed connected to the trigger must be cleaned thoroughly
and all grit and sand particles removed.
Do not use any solvents or petroleum-based products.
The ADV must be stored in a cool, clean, and ventilated place, in an
upright position with the nose facing upwards. The battery must be
removed, charged and stored away from frosty conditions or excessive
heat. Make sure that the connectors do not come into contact with metal
objects inside the ADV or the battery will be shorted. The wheel for
opening the head cap must be loosened such that the gasket is in view.
Important note: always remove the battery after the use.
26 M
AINTENANCE
Lubrication of head cap O-ring case
Open the ADV, gently remove the lock O-ring (19) (see fig. 6) being careful not to scratch
the O-ring support surfaces, and clean the seating thoroughly (only by means of a clean
brush or soft cloth). Do not use any type of solvent or alcohol. Apply silicone oil to the Oring and return it to its place. Do not use any other type of oil!!! We recommend the aerosol
spray type which is usually used for diving equipment. Occasionally, lubricate the lock
knob screw with normal mineral grease. Never lubricate trigger or magnetic piston
movement. They would fill of sand and dirt. Do not lubricate electrical contacts!
Closing knob gasket maintenance
Whenever the closing knob (9) (see fig. 1) comes into contact with sand, rinse with running
water before rotating it. About every 50 uses, remove it, using pliers, clean the gaskets
and lubricate with silicon oil, If you are not familiar with this operation, contact an
authorized service centre.

Supplementary maintenance
Every hundred hours of use or at least every two years, we recommend you overhaul the
ADV checking hydraulic seals and electrical circuits.
SUEX S.r.l. fully overhauls your ADV with shipping throughout the world.
NOTE: using spray lubricants, it is important to air the inside of the ADV.
In this way the propelling gas go away, for the most part are
inflammable!
27 D
ISPOSAL AND SCRAPPING
This apparatus is partly constructed with recyclable materials.
When the ADV can no longer be used safely or when the service centre deems it no
longer suitable for use, the ADV must be scrapped.
The ADV must be disassembled and divided into distinct parts. Plastic parts must be
deposited in the relative plastic waste containers and metal parts must be taken to a
collection centre for metal waste.
Special care must be taken when disposing of battery
packs, which are highly polluting to the environment.
Batteries must be taken to a collection centre for spent
batteries.
PLEASE SAFEGUARD YOUR SURROUNDINGS!! ALL VEHICLE PARTS AND THE
BATTERY PACKS IN PARTICULAR SHOULD BE DISPOSED OF ACCORDING TO
LOCAL DISPOSAL REGULATIONS!
28 H
ANDLING
In every transport condition, the ADV must be always closed.
The vehicle has been conceived for use in water environments. When transporting it or
loading it onto a car, some precautions need to be taken due to its shape and weight.
Lift it holding a flow conduit support and front handle.
Whilst transporting it by car or by boat, make sure it is blocked in a secure position. If not
blocked it could easy roll and cause damages to property and personal injury.
The use of the support cod. 70068 is advised (see Suex accessories).
Do not position the ADV at the front of boats or dinghies or in positions where it would be
subjected to harsh jolting the inner parts may be damaged. When the ADV is laid on the
ground, always do so gently, and when it is placed in the upright position, rest it on the
propeller guard. Always make sure that the surface is flat and that nothing comes into
contact with the propeller.
If you prefer to grip the ADV from the maneuvering handles, do so, but do not overstress
them - they were not designed to bear excessive loads. Do not carry the entire weight of
the ADV on only one handle.
