WARNINGS
Warning: Never drive through sea grass, mud or silt. This can
block the propeller. If something gets into the propeller, remove
the fin from the water, dry it completely and then remove the
foreign object with a tool. Never put your fingers into the pro-
peller.
Warning: Always make sure there is enough draft (> 0.5 m)
before you lower the board with the E-Fin into the water. In the
water, you should always keep an eye on shallows and keep the
minimum distance between the E-Fin and the bottom.
Warning: Do not open or tamper with the electronics housing.
You could get an electric shock. In addition, the warranty would
no longer be valid.
Warning: Always make sure that the screws of the adapter are
tight. Also make sure that the fin is properly stowed in the box
and that the box fixes the fin.
Warning: Be careful not to get your fingers, hair or clothing into
the propeller or other moving parts.
Warning: Always keep the E-Fin out of reach of infants and
small children.
Drive responsibly and respect those around you. How you drive
affects how this new mode of transport is seen by others.
SAFETY INFORMATION
The E-Fin is operated by a propeller.
To use it safely, you have to read all warnings and instructions in this
manual.
The E-Fin may lose drive at any time.
This can be caused by radio interference, an empty remote control
battery, accidental adjustment of the power regulator or other
factors. Use the power of the E-Fin on your SUP or kayak only as you
would trust yourself to do without a drive.
Take care of your environment.
Avoid driving near breeding birds, seal banks or similar
animal-inhabited areas.
Riding on water recklessly can lead to death.
Always be careful when you are out on the water. Always drive
defensively and assume that others don‘t see you. Don‘t ride in strong
waves (waves > 0.5 m) or storms. Do not drive in shipping lanes or
cross the course of larger ships. lf possible, avoid paddling through
fog at night or when visibility is poor.
Comply with the local laws.
There are rules and bans on different waters. Familiarise yourself
with the local laws, pay attention to bathing areas and other areas
that are closed to water sports.

4. 1 REMOTE
The control is simply clipped onto the handle of the paddle at selected
height. lt must be mounted parallel to the paddle and point towards
the driver.
4. 2 E-FIN
To mount the E-Fin, turn the SUP/board on its back so that the fin
mount is facing up. Depending on the fin mount on your board, choose
the right system and screw the adapter onto the E-Fin with the three
screws and allen key provided. Make sure to tighten the screws only
lightly and without great force so as not to damage the adapter. The
E-Fin then can be attached to your board.
4. 3 US-FINBOX SYSTEM
The US finbox system has a standardized fin box. Here the fin is fixed
in the box with a small washer and a screw. The whole thing works
without tools, as the screw can be screwed in by hand. This system
requires some dexterity to get the plate through the fin. The more often
the fin is installed, the easier it will become.
4. 4 SLIDE-IN SYSTEM
This system is very easy to assemble. The fin is simply pushed into the
box and then secured with the small pin (on the strap).

a. The supplied charger should be checked regularly for damage to the cable, plug,
housing and other parts. If there is any damage, do not charge the E-Fin until the
charger has been repaired or replaced.
b. Do not expose the charger to moisture or extreme humidity. Do not charge the
JayKay E-Fin and the JayKay controller outdoors or in the rain. Dry the charging
ports before charging.
c. Stop charging if charging of the E-Fin and/or remote is not completed in the
specified time. Stop charging if the batteries become unusually hot, begin to smell,
become discolored, become deformed or if you or if you notice anything unusual
during use, charging or storage.
d. Do not charge the E-Fin if the battery case is cracked, swollen, or shows other signs
of damage. Discontinue use immediately and dispose of the the battery immediately.
5. 4 E-FIN CHARGING AND CONTROL
Both devices have a battery-saving charging time of 3 hours. The
charging time of the E-Fin and the controller can also vary here. Char-
ging is done via the included charging cables with the corresponding
power supply unit.
5. 1 TURN ON AND OFF
The fin turns on when it is immersed in water with the charging port.
The fin switches off when it is removed from the water. The control is on
in the rotary wheel position „AUTO“ or „MAN“ and off in the rotary wheel
position „OFF“.
5. 2 CONNECTION BETWEEN REMOTE AND E-FIN
The E-Fin is delivered already coupled. However, if the E-Fin needs to
be coupled again for any reason, please refer to chapter „6. 6. Menu
item 2: Pair E-Fin(s)“ on page 13.
5. 3 BATTERY LEVEL INDICATOR
The battery runtime can be checked via the remote. The upper row of
LEDs shows the battery level of the E-Fin, the lower row of LEDs shows
the battery level of the remote.
a. The remote is on, but the E-Fin is off:
white LEDs flash (according to the last battery level).
white LEDs light up.
The battery level is shown by the number of LEDs lit up.
b. The remote and E-Fin are on:
white LEDs light up.
white LEDs light up.
The battery level is shown by the number of LEDs lit up.
c. The 6 battery states:
lf the devices are full, all 5 LEDs light up white. lf the battery level is reduced, the
LEDs also go down. lf the battery level is very low and the devices should be charged,
only one red LED will light up in the display.
5. INSTALLATION
Note: In order to switch on the E-Fin
it must be completely in the water.
Warning: Never leave the E-Fin/remote
unattended when charging.
Note: If the temperature of the E-Fin is above 45 °C,
charging is inhibited until the temperature is below
the limit of 45 °C. If the charging time is over
3 hours, this case has occurred.
