USER MANUAL
MY EFOILPWR-FOIL,A BRAND BUILT
ON PASSION
It is important to keep the original boxes and foam packaging for all future shipping, including
for maintenance / returns & repairs / resale. No returns under warranty will be accepted if the
product is not shipped in the original packaging and padding.
This instruction manual is also a maintenance booklet. It must always be kept with the product
for maintenance or resale purposes.
Passionate about surng and an entrepreneur at heart, I have built my life around these two
pillars. 5 years ago, living for more than 10 years the incredible experience of Redwoodpaddle,
a brand of inatable and rigid stand up paddles and surfboards and accessories, I wanted more
glide on all water bodies in all circumstances ... ;)
I began to dream of ying over the water!
In 2016, this idea was a bit crazy.Like all enthusiasts, I am curious, I seek, I develop.The desire
to y whatever the weather conditions is very present, prevalent, too strong to stop there... The
idea of an electric foil is born... No efoil exists yet in the world. A team of enthusiasts was created,
each one highly competent in his eld. PWR-Foil is born!
In 2018, we present the prototype at Nautic Paris.
In 2019, we take the rst orders.
In 2020, PWR-Foil efoils are ying all over the world. 2021 conrms the brand in its eld, you
customers are our best prescribers!
2022 promises to be an incredible adventure! We are working to inscribe our companies, our
brands, our products and ourselves as a team, in an approach where economic logic, social
responsibility and eco-responsibility are naturally linked. We move into a 1500m² solar powered
facility, have all our aluminum and injected plastic parts manufactured within a 200km radius,
and integrate internally the production of all carbon parts. We support campaigns in the health,
social and environmental sectors: Pink October, Movember, «1 efoil bought = 1 tree planted»
during the months of December and every 21st of each month. We are thinking about adapting
our work to better practices, to install and establish a Green approach in our processes. The
wood used for our boards is paulownia, a fast-growing tree with exceptional ecological virtues: it
is able to absorb up to ten times more CO2 than most other plant species; we recycle your suits
in a solidarity workshop 10km from our home; we create our 100% local t-shirts in this same
workshop; we have switched to eco-packaging for all our boards; we favor rail transport for the
delivery of our parts as soon as we can.
Personally, I love the efoil, it’s addictive!!! No two days in a row go by without me being on the
water... As much for the fun of it as to keep improving it.
The very rst time I ew more than 5 minutes, ... Wow... I went home with a smile on my face and
the feeling of having touched the stars ;)
I wish you the same! The same pleasure!
The same adrenaline rush with every ight!
Until I have the pleasure to meet each of you
and to share a nice session together, I hope
you will take as much pleasure in ying as
we do in developing this beautiful toy. CONTACTS

2. WARNINGS
> Negligent behavior and errors in handling this product expose you and others around you to an
elevated risk of injury or death and/or damage to your PWR-Foil or other equipment.
> Use common sense and basic safety precautions when using a PWR-Foil. Rudimentary
mechanical skills are also required.
> It is strictly forbidden to use a PWR-Foil with incompatible components or to make any
modications using components other than those exclusively sold by PWR-Foil.
> A PWR-Foil should not be ridden or handled by children under the age of 16. It is not a toy.
> A PWR-Foil is an electrically powered watercraft that requires care and and responsible
piloting.
> Like any other electric vehicle, it must be regularly maintained and serviced once a year to
keep it in perfect working condition and avoid breakage. An overhaul should be performed
12 months after the date of receipt of your efoil or 100 hours of ight time, whichever comes
rst. Contact PWR-Foil for details on how to have your efoil serviced. The PWR-Foil Limited
Warranty is void if the overhaul schedule is not followed.
> It is important to ensure that the water is at least 1.5 meters deep - never y in shallow water
/ in rocky areas / in bad sea conditions.
> It is strictly forbidden to tow any other watercraft or person (surfboard - paddleboard - jet-ski -
boat - swimmer - water-skier, etc.). This action would be tantamount to grossly exceeding the
maximum authorized load, potentially overloading the motor and electronics and seriously
damaging your PWR-Foil. Any ensuring repairs will not be covered by the warranty.
ADDITIONAL RECOMMENDATIONS
> Always check local regulations: Depending on the region and country, the body of water may
be regulated and a permit or fee may be required to operate the PWR-Foil. Please check with
the relevant authorities in your country.
> I can swim. I use a leash. I always use an approved safety helmet.
> You must always keep a safe distance from others on the water, including boats, swimmers,
surfers, paddle boarders, etc., and respect marine life. The PWR-Foil is not intended for use in
surf or breaking waves. Users who venture into these areas do so at their own risk.
> I consult the weather forecast for the entire day: waves, offshore wind which pushes away
from the coast, I don’t go out in stormy weather.
> I notify someone of my departure. I sail with at least one other person.
> Learn about the area before getting in the water (tides, currents, river diculty level, depth,
etc.).
> Do not use after having imbibed alcohol or ingested psychotropic drugs or any medication
with the potential to alter your personality.
> Be careful not to overestimate your physical and technical abilities.

3. PROPER USE
THE PROPULSION SYSTEM
The PWR-Foil’s propulsion system consists of a
powerful electric motor and a propeller spinning
at a very high RPM.
> It is imperative that you keep your body, ngers
and feet away from the propeller at all times,
whether it is in motion or stationary. Failure to
do so can lead to serious injury and even death.
> Never touch the propeller either in or out of
the water.
> It is strictly forbidden to disassemble the
propeller while the PWR-Foil battery is
connected to it.
THE HYDROFOIL
The PWR-Foil hydrofoil system includes a mast, a main lift
wing (front wing), a stabilizer (rear wing) and a fuselage
that connects the mast to the front and rear wings.
> These elements all possess a sharp leading edge. Great
care should be taken when handling the PWR-Foil to
avoid bumping into them both in or out of the water.
> Falling on the foil (mast or wings) can cause serious
injury or lead to death.
IN GENERAL
> Do not leave your equipment out in the sun, either on
top of the car or in the car.
> We strongly recommend that you seek professional
help to learn to use your PWR-Foil:
- From the PWR-Foil team
- From a rental place with a training staff. A list of
clubs is available online at www.pwrfoil.com.
> We recommend that you watch our explanatory and
demonstration videos to learn the correct techniques for taming your
PWR-Foil and using it safely in all circumstances. Scan the QR code to
view our YouTube channel.
THE REMOTE CONTROL
> The remote control must never be stored with the magnet of the circuit breaker. This would
disrupt the remote control’s sensors.
> Never leave the remote control on the charging stand for more than one hour.
Never leave it overnight on charge for example.
The battery would deteriorate rapidly and the remote control would not light up.
> Never connect the charging stand to a charger of more than 2.4A (5V).
> If the remote control ashes during charging, the charger is not good!
> Clean the male and female connectors on the board with WD40 CONTACT. Grease the female
connectors as well as the 8-pin female connector on the board with marine grease. It is this
connector that allows the ow of information from the board to the remote control.
TRANSPORT
It is strongly recommended that you use the packaging foam for all transport.
> It is totally forbidden to transport batteries by plane. When transporting by land, the UN 31
document must travel with the battery.
> The Efoil system can travel by plane. The water tank of your Efoil must be carefully emptied and
the system must travel with the tank cap open.

THE BATTERY
> The PWR-Foil battery can be used between 0°C and 40°C.
- Never heat your battery, never expose it to a heat source, never leave it in direct sunlight.
Any use above 40°C can cause a re or an explosion.
- Never put your battery in a refrigerator, freezer or pressurized container. Any use below 0°C
can cause irreversible damage to the battery.
> Never attempt to disassemble a PWR-Foil battery as this may result in a battery leak, re
or explosion. The electrolytes contained in the cells that make up the PWR-Foil battery are
extremely corrosive.
> Only use a PWR-Foil battery with your PWR-Foil system. Doing otherwise will void the warranty
for both.
> Never charge a PWR-Foil battery that is damaged and/or has been hit or dropped. Since the
battery contains a large amount of energy, charging a damaged or compromised battery can
result in a re or even an explosion. It is essential to thoroughly inspect your PWR-Foil battery
before use.
Signs of a damaged PWR-Foil battery:
- loss of retaining screws
- Deteriorated or torn connector / loose or damaged terminal
- fractures/cracks/splits on any surface of the case
- housing is deformed, swollen
- smell of acid emanating from the battery
- very high heat > 80°C when charging
> If your PWR-Foil battery shows visible signs of damage and falls into water, the waterproong
may be compromised:
- Take it out immediately and put it in a safe, open space.
- It is essential to keep a safe distance until it is completely dry.
- Never use this PWR-Foil battery again.
> It is strictly forbidden to dispose of a PWR-Foil battery improperly.
Before disposing of a PWR-Foil battery, it must be completely
discharged and disposed of in an appropriate disposal bin for recycling.
It is imperative to check and follow up-to-date regulations in the country where the battery is
being disposed of. Every battery is stamped with a specic identier allowing it to be tracked.
> If a PWR-Foil battery catches re, the re must be extinguished using a powder extinguisher.
> Always place the PWR-Foil battery indoors in a well-ventilated area and on a surface with
improved heat dissipation (e.g. a concrete oor), never on a wooden workbench or shelf. It
is imperative to keep at least 50cm between each element: battery and charger and between
multiple batteries and chargers, if you own several. Do not place any objects or chargers on the
battery.
> The charger must be used at a standard voltage of 220/240V on an outlet that can handle the
1500W power of the charger. If you have 2 chargers, it is imperative that they be plugged in
to separate outlets (never simultaneously on a power strip). Never disassemble the charger, it
could cause a fatal electric shock.
It is strictly forbidden to:
- Place a charger on a battery and charge the battery,
- Cover the charger when it is in operation,
- Charge the PWR-Foil battery in a humid environment, or in an overly hot environment, or near
ammable or explosive materials,
- Leave the charger plugged in when no battery is charging.
> It is imperative to monitor the PWR-Foil battery while it is charging (to be present during
charging) and watch for any anomalies, such as:
- overheating
- smoke
- abnormal smell

- The power chords (red and black chords of the electronics case).
- The chords as well as the case and various parts of your charger.
> It is essential to systematically rinse the entire system with clean water:
- the complete e-foil system including the connectors (except for the 8-pin connector, which
should be cleaned with WD40 contact cleaner).
- Dismantle the e-foil system and the battery to rinse the holder and remove sand to avoid it
getting into the screw inserts (see Safety and Precautions p.7).
- The batteries should not be placed in the sand or on the ground to avoid scratches or sand
damaging the seals (see p.7).
- The remote control, make sure to let the water run into the seams along the triggers.
> It is essential to clean the male and female connectors on the board with WD40 CONTACT,
including the 8-pin pin.
> It is essential to dry well before reuse:
- the battery contactors before connecting them to the charger
- the remote control before putting it on the charger’s support
> It is essential to grease the female connectors as well as the 8-pin female pin on the board with
marine grease as well as each xing screw.
REGULAR MAINTENANCE
EVERY 30 HOURS
> Marine grease: it is important to dismantle the wings/fuselage/mast/propeller and propeller
guard and to meticulously grease each insert, each screw, each nut and each thread.
> WD40 contact cleaner: regularly clean the 8-pin connector with WD40 contact cleaner (and put
some marine grease on the female connector), as well as on the nuts and threaded rods of the
nose cone and the propeller shaft outlet.
> For machines that were used in salt water, let the motor soak several hours in a fresh water in
order to dissolve any traces of salt.
> Meticulously grease each insert, each xing screw, each nut, each thread and threaded rod of
the front cone and the propeller shaft outlet, as well as the 8 pin and all connectors.
> Change the water in your tank if it is demineralized water.
EVERY 6 MONTHS
> Drain and replace the coolant (see page 32).
5. WINTERIZING
> As with any mechanical device, it is advisable to run your efoil for a few minutes once a
month or so:
- You can just dip the part of the mast where the motor is located in a tub of fresh water to
get it running.
- Finally, if you want to keep your batteries unused for a long period of time, they should be
charged at around 45v or 30%.
> It is recommended you dismantle all components and store them in a safe place to avoid
any damage: original foam in the PWR-Foil bag.
> Your PWR-Foil must be stored in a dry and clean place. All components, e-foil system /
PWR-Foil remote control / PWR-Foil battery must be completely protected from the sun
(see Safety and Precautions p.7).
> We remind you that lithium-ion batteries are dangerous, highly ammable or explosive
devices. it is therefore advisable to store them in a dry room away from the sun, any heat
source or ammable products. the ideal storage temperature is between 20/28°C. Do not
charge your battery to the maximum for a long period of time, charge it to between 44 and
48v, check with a voltmeter (see Safety and Precautions p.7).
> It is forbidden to clean the various components of your PWR-Foil with alcohol-based

1. CONTENTS
BOX 1: THE BOARD
Our construction technique guarantees boards that are both strong and light. Our boards are
made from an EPS HD slab shaped on a 4-axis CNC machine, then laminated with epoxy, ber
and carbon. They are then reinforced with a paulownia sandwich. In addition to the obvious
strength attributes of paulownia, the wood lends a true aesthetic appeal to our line of boards.
The shape takes advantage of a double concave, making it easier to take off as well as touch&go
with as little braking as possible.
It is important to keep the original boxes and foam packaging for all future
shipping, including for maintenance / returns & repairs / resale. No returns under
warranty will be accepted if the product is not shipped in the original packaging
and padding.
BOX 2: THE BATTERY
We are proud to offer batteries manufactured in France. The lithium-ion cells are sourced from
the best suppliers to ensure top quality. At our production site, the cells are cast in resin inside
the case to ensure a rst level of waterproong. The cover of the box is then sealed to create
a second watertight barrier. The aluminum of the case also plays a role in
continuously cooling the battery.
With the supplied 20A charger, your battery will fast charge in about 1.5 hours
and provide approximately 1.5 hours of use... Approximately, because battery
life depends greatly on your size and your ight experience. A lithium-ion
battery can be charged between 1000 and 1200 times.
You can connect to the long range battery via Bluetooth with the free app
SMART BMS. It allows you to track battery voltage and temperature in real
time. Among other advantages, this allows you to check that your battery is
between 5 and 35° for better operation and longevity. The battery can also be
accessed remotely by PWR-Foil for troubleshooting.

>A MAGNETIC CUT-OFF FOR YOUR SAFETY AND THE SAFETY OF THOSE AROUND YOU:
An essential safety element, we have spent a long time developing a 100% ecient system.
This leash cut-off is the main element guaranteeing your safety. A 1m long leash is attached at
one end to your ankle (front foot) or waist, and at the other end to a magnet with the equivalent
of 25kg of pull. When this magnet is in contact with the board, it closes the electrical circuit, and
the motor runs. When you fall off the board, the short length of leash attached to your ankle or
waist pulls the magnet loose from the board, opening the electrical circuit and instantly cutting
off the motor and stopping the propeller.
>AN INTUITIVE REMOTE CONTROL
As with the battery, we are proud of the technological developments of our remote control. It
is ergonomically designed to offer a perfect grip with the control screen facing you and the
trigger for the throttle at the tip of your index nger. A exible resin completely surrounds all
the electronics and ensures that the remote stays waterproof. The remote control is held to
your wrist by a buoyant strap, so you don’t need to worry about losing it mid-ight.
>MAST / FUSELAGE / WINGS
Our mast, specially developed and designed for our foil, is made of marine anodised
AL6061 aluminium. One of the great properties of nautical aluminium is its ability to transfer
temperature. Our cooling system is therefore naturally installed in the mast. The electrical
cables also run inside. We opted for an 80 cm mast because whatever the conditions, whether
it’s glassy, rough or even in the waves in surf mode, this length brings ideal comfort and always
that incredible feeling of ying over the water. The fuselage is also made of AL6061 marine
anodised aluminium for the same mechanical characteristics. We wanted it to be streamlined
in order to reduce disturbances as much as possible. Our wings are manufactured with a CNC
machined PVC core which gives them good otation and lightness. They are then laminated
with pre-preg carbon and heat moulded to provide increased sun resistance and strength.

2. CHARGING THE BATTERY
Remove the PWR-Foil battery from its packaging. Do not throw away the packaging in
case you need to return the battery to the factory.
Inspect the battery carefully and, before charging it, it is imperative to check that no
damage has occurred (see p. 12 & 13 of this manual).
Connect the charger to the PWR-Foil battery, making sure that the polarity is correct: red
charger terminal to red battery socket, black charger terminal to black battery socket.
Find a safe location and safe outlets (see p. 12 & 13 of this manual), then plug in the
charger.
Charging begins. It is imperative to monitor a PWR-Foil battery during charging in order to
watch for any potential anomalies (see p. 12 & 13 of this manual).
PWR-Foil batteries are equipped with several safety features (reverse polarity / temperature /
automatic charge and discharge balancing / over-voltage / undervoltage / short-circuit) to provide
as much protection as possible. However, human supervision remains essential during the
charging phase / after a session and discharge / after transport or during handling.

6. FILLING
THE COOLANT
RESERVOIR
WARNING
> Your PWR-Foil is equipped with a thermal protection, a failure of the water pump or of the
cooling system will cause your machine to stop immediately.
- If this happens, do not use your PWR-Foil as it could lead to overheating of the electronics
and irreversible damage, resulting in expensive repairs.
+ +
ou
Lay your mast down, making
sure it is well supported. With
a funnel, ll the tank.
Close the cap.Unscrew the cap on the case
of your efoil.
Your Efoil will arrive with an empty tank.
You should use demineralized water
to feed the cooling system tank
of your PWR-Foil, which should be
changed every month.
If you do not wish to change the coolant regularly, it is also advisable to use distilled
water to which you add a biocide and an anti-corrosion liquid (additives available from
suppliers of liquid cooling systems for PCs) to avoid clogging the system, deterioration
of the pump and redox phenomena. It will then be necessary to drain the system every
6 months.
The coolant should be changed at least once every 6 months if the water is distilled with
biocide and anti-corrosion liquid. Otherwise it is better to change it every month.
In hot weather, it is recommended to lower the coolant level very slightly to avoid
excessive pressure inside the tank.

ASSEMBLY
REMEMBER
> It is imperative to apply marine grease before each assembly:
- each screw holding the efoil system
- the 8-pin female connector, as well as on the external thread.
> It is imperative not to force when connecting the 8-pin plug and to respect the indexation.
> The 8 pin connector must always be clean, dry, greased and free of foreign matter (dust,
sand...) must be on the connectors at the risk of damaging them and making your pwr-foil
totally inoperative.
> After each use, it is recommended to clean these plugs with a wd40 contact spray only, and
re-grease immediately.
> If by accident during assembly or disassembly, a plug should come into contact with water, do
not connect it and do not power up your pwr-foil by connecting the battery. Water inltrated
in the pins could cause a short circuit making your pwr-foil totally inoperative and irreversibly
damaging some electronic components. If such a mishap happens to you, let the contactors
dry at least 24 hours before reconnecting them and clean them with the wd40 contact, then
regrease before reconnecting.
Lay your board with the anti-slip pads against
the ground.
