Main Security checkS
1. Main Security checkS
It is important to get familiar with the board’s security systems before starting
to enjoy it. Please make sure you use the boards 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 Twin.
• When entering the water, you must avoid entering through wave
breaking 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 jet is powerful and could cause 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.

b) diSconnection
Avoid pulling from the cable, always pull
from the connector body.
c) iMPortant
Always supervise the charge, do not leave
the battery unattended while charging.
• The battery does not need to be fully discharged before charging. A
Lithium Ion battery doesn´t have memory effect. This means that
the maximum energy capacity won´t be aected if it´s charged after not
being fully discharged.
• Make sure that the battery does not remain connected to the
charger after the charge has been completed.
• Always remember to close the battery rubber connector covers
before use.
• The temperture use for the battery must always remain between 0 ºC y
60 ºC (32 ºF y 140 ºF).
• Extreme temperatures will aect the battery life, especially during
charge. Avoid charging the battery while being exposed to direct sunlight
or extreme high or low temperatures. The charge is recommended to be
carried out with temperatures (between 10 ºC y 45 ºC / between 50 ºF y
113 ºF).
• Do not overdischarge the battery. Do not continue riding once the
power starts to decrease and the LEDs on the top bar begin to blink, this
has been proven to decrease the battery’s capacity over time. This is an
extra energy resource which must be used only for emergencies.
4.2. wireLeSS controLLer
To activate the board you must press on the drop. The power of the Jet will
depend on the amount of pressure exerted on the drop.
4.2.1. controLLer conFiguration

• 2 LEDs: Staggered 2. This prole has three power levels. The
rst one allows us to activate the jet at a low potency in order to go at
slow speeds (for example, to go from shore to a safe cruising area). The
second power level will allow us to decrease the power consumption
once planing is reached so we can get more battery life.
• 3 LEDs: Staggered 3. This is a prole similar to the previous
one with the difference that the second power level is at a higher
power. In case that ¨Staggared 2¨doesn´t allow us to reach planning
we could use this one.
• 4 LEDs: 100% / 0%. The jet will from 0 to 100% power
by pressing on the drop. This will be the most comfortable
setting for those wanting maximum power throughout
the ride but the battery life will be compromised.
• 5 LEDs: lineal. On this profile, the jet reacts
lineally to the pressure on the drop. It requires a bit more
of skills in order to use the entire range appropriately.
