Main Security checkS
1. Main Security checkS
It is important to get familiar with the board’s security systems before starting
enjoying it. Please make sure you use the board following the instructions
provided in this manual.
• Always check the unit before entering the water. Make sure the
board, the safety disconnection system, the battery and the wireless
controller are in good condition.
• Do not lend your equipment to anyone who has not been instructed
in the use of the Manta.
• When entering the water, you must avoid entering through wave break
areas and in case of doing so, you must always place yourself between
the board and the wave. This way the board will not harm you in case a
wave strikes you.
• Never practice this sport if the conditions exceed your skill level.
• Always wear the Leash attached while using the unit.
• When getting on the board you must always do it from one side, even
in areas of high depth. The water jet has great power and could caus e
injuries.
• Never place your hands or feet near the impeller. The suction force
from the jet is very powerful and it could drag them to the interior. Even
with the battery disconnected you must be aware of the impeller since
the leading edges are sharp and may cut.
• You must take into account that the board does not have a braking
system. Although you may discontinue to press the throttle, the board
will continue moving forward due to its inertia. This route can be relatively
long if you want to move from the glide status to the stopping one. It is
recommendable to slow down as you approach the target area where
you want to stop.
• Do not touch the steel tube right after use since it could be at elevated
temperature.

05Safety GuidelineS
5.4. getting out oF the Water
• Do not activate the jet outside of the water. The propulsion system is
not meant to be used outside of the water, this could signicantly damage
the jet.
• After a long use going full thrust, it´s recommendable to wait at least
one minute for the jet not to overheat.
• It is not recommendable to step on the battery surface. Although
it’s designed to hold weight, when stepping on it, the watertight seal
compresses facilitating water to get in.
5.5. generaL Security MeaSureS
• This board could reach high speeds. It is recommendable to use a life vest
and a helmet while operating this product.
• Do not go further o shore than you can return swimming and always
have someone watching from shore. Do not operate this product alone.
• Be aware of climate changes or any other sudden change in the located
area (tides, shallow waters,..). Do not use this product while electric
storms.
• Do not use this product near swimmers or scuba divers.
• Make sure that the water is deep enough to operate this board, be aware
of coral reefs.
• Do not operate in areas of high current or waves. The Manta is not
meant to be used to surf waves. In case of being tilted by a wave, the
rider could suer severe damages.
• Do not use behind another board. In case of doing it, make sure you
have enough space to turn in case the rider ahead falls.

Maintenance of the equipMent
6.1. board Maintenance
• It is recommended to rinse the jet with fresh water after every use. When
using in extreme saline environments, it´s recommendable to ash the
entire intake area with fresh water. This way the user will get rid of all the
excessive salt in the shaft and impeller.
• Do not leave the battery connected. To disconnect is, it´s necessary to
take it out of the board. The battery powers the board from the moment
it´s inserted. Although the power consumption is very low, it is not
recommendable to leave it inside for long periods.
• Clean the stainless steel tube frequently. With every use, a small layer
of salt could build up over the surface. Given that the tube´s surface is in
charge of heat dissipation, it´s extremely important to have it clean for a
proper dissipation.
• It is not recommendable to place it upside down and never exposed to
direct sunlight over long periods of time.
• Periodically apply blue grease on the impeller and stator/nozzle.
• Periodically apply grease on the impeller, stator/nozzle and male and
female connectors.
• Between uses, always keep the discharge connectors clean.
• Do not impact the turbine or rest the board over it.
6.2. battery Maintenance
• It is crucial to handle the battery correctly while having it outside
of the board.In case of dropping it and due to its large weight, the
watertight seal could break. Do not use the battery if it has been dropped
and contact the support team immediately.
• In case of break, dint or any other form of apparent damage, do not
use the battery.
• It is recommendable to store the battery in a dry place and not exposed
to direct sunlight.
• Do not submerge the battery.
• Do not throw the batteries away. The batteries must be properly
destroyed at recycling facilities.
• Keep the male and female connectors in good condition always.
Maintenance procedure: unscrew the female connectors from the battery
and the male connectors from the board. After that, clean them with
isopropyl alcohol and apply white grease (for electronic contacts). Screw
the female connectors to the battery and male connectors to the board.
The lack of maintenance or lack of tightness on the connectors could do
irreversible damage to the board.
• Unless in charging, protect always the battery´s connectors with the
plastic cover. The plastic covers avoid entering water inside the connector.
In case you forget protecting the the battery´s conector water could
damage the battery irreversibly.
