– Check the fuel tank before every ride to make sure that you have enough fuel for the time you
have planned to spend on water. If you do not have enough fuel in the tank, your motorized
power board might run out of fuel and you can get stuck far from the coast or bank. It is in
responsibility of the user to prevent such situations. A low fuel level may also inuence the ope-
ration. As a result of moving on the water surface, the fuel may ow from side to side in the fuel
tank which can lead to uneven fuel distribution into the engine misses. If necessary, always return
to land and top up the fuel.
– On such an occasional also check whether there is not water or fragments in the tank. Water
stays at the bottom and leaking of water into the tank suggests a problem which has to be solved.
Water in the fuel system may cause that the engine will run badly or not at all. Remove the water
and destroyed petrol and oil mixture properly and then ask your JetSurf™ sales representative
for help in order to nd the reason why the water leaked into the tank if it is not an obvious and
easily rectiable cause.
– If it is clear that there are fragments in the fuel tank, do not start the operation of the motorized
power board. The fractions might block the fuel system and cause failure of the engine and the
user may get stuck far from land. Before starting again, it is important to nd out how the frag-
ments got into the fuel system.
– If you nd an obvious damage or leak of the fuel tank or fuel system, DO NOT START
THE ENGINE! Immediately call the authorised sales representative and service of JetSurf™ to
assess the fault. Leaking fuel may cause serious damage to the environment and it could be a
potential dangerous situation for people and assets.
Petrol is extremely inammable and highly explosive. Never smoke or
handle re within fty (50) feet / fteen (15) metres from the fuel area
when topping up fuel. Avoid spilling the fuel. If spilt, dry the fuel with
cloth and dispose of it on land. Never start the engine when you can see
or smell fuel, as vapours can be more explosive than liquid fuel.
If fuel can be seen during the operation, switch the engine o immedia-
tely and nd assistance as soon as you get to land. Have the engine and
the fuel system repaired by an authorized JetSurf™ seller before restar-
ting the operation.
FUEL TANK
Use lead-free car petrol
with the octane number
95 or higher mixed in the
proportion of fty (50)
parts of fuel to one (1) part
of MOTOREX OCEAN FS
2T BIO; or oil meeting these standards:
NMMA TC-W3, API TC, ISO-L-EGD: JASO
FD/FC; TSI. Bad mixing or use of petrol/oil
other than the prescribed one may lead
to the engine damage. These cases can-
not be covered with the guarantee.
Fuel system consists of the fuel tank, a fuel
lter (placed inside of fuel tank), fuel hoses
and a carburetor. JetSurf™ has venting hose
which leads from fuel tank up to the air intake
in front part of the board.
The fuel tank can be removed easily by relea-
sing clips (couplings) in the fuel route which
are situated near the carburettor. (See the instructions specied below in the user manual where you
can nd complete instructions how to remove the fuel tank correctly).
Using of the correct petrol and oil mixture is crucial for ensuring long-term use of the motorized
power board. Using of petrol with an incorrect octane number or oil not meeting the specications
may result in permanent damage to the fuel system and/or the engine which is not covered with the
guarantee. Apart from the above specied, please observe the following measures:
– MOTOREX OCEAN FS 2T BIO oil can be replaced with a quality fully synthetic oil intended for ra-
cing two-stroke engines meeting the standards NMMA TC-W3, API TC, ISO-L-EGD: JASO FD/FC; TSI.
– Never use cheap oil intended for garden machinery or similar mechanical devices.
– DO NOT USE synthetic oils intended for use in the engines fuelled by methanol (castor oil)
– Fuel is to be stored only in containers intended for that purpose. Such fuel containers must have
D.O.T. approval or CE (for Europe) – specied on the device.
– DO NOT USE mixed fuel older than sixty (60) days.
– If it is necessary to remove the fuel from the fuel tank, perform it in a well ventilated area and
dispose of it on land. Observe the safety instructions specied in this part of the user manual.
Handling of fuel or fuel vapours requires full concentration and correct procedures.
– Never try to suck the petrol up with your mouth. If you swallow some petrol, inhale its vapours or
if it gets into your eyes, consult a physician immediately. If petrol gets in contact with your skin,
wash the aected place with soap and water. If petrol gets onto your clothes, take them o and
let them dry. Wash the clothes after proper drying.

CONTROL HANDLE
The engine shut-o key must be attached to the rider’s wrist during the
operation. If the rider falls o or is pushed o the motorized power board,
the key will be pulled out of the engine shut-o switch and the engine
will switch o automatically. It will quickly stop the forward movement
of the power board, which not only enables the rider to return to the
power board but it also prevents the motorized power board to continue
its forward movement, which might lead to its damage, damage to other
vessels in its surroundings or injuring any people, including the rider.
NEVER LEAVE THE ENGINE SHUT-OFF KEY INSIDE ENGINE SHUT-OFF SWITCH
LONGER THAN 30 SECONDS IF YOU ARE NOT GOING TO CONTINUE IN YOUR
RIDE. LEAVING THE ENGINE SHUT-OFF KEY INSIDE HANDLE FOR LONGER PERI-
OD OF TIME (IE OVER NIGHT OR WHEN TRANSPORTING THE BOARD) CAN LEAD
TO COMPLETE DISCHARGE AND NON-REVERSIBLE DAMAGE TO BATTERIES.
The motorized power board is supplied with the control handle which controls the engine output.
The handle is supplied together with the engine shut-o key which is used for the power board ac-
tivation and starting.
It is comprised of:
- Engine shut-o switch (marked 1); - Speed limiter (included in the accessories) (marked 4);
- Throttle trigger (marked 2); - Connector to the ICU (marked 5); and
- Engine shut-o key (marked 3); - Throttle cable (marked 6).
The throttle trigger is situated on the handle, at the end of the throttle cable. JetSurf™ recommends
controlling the throttle with your index nger. When the throttle trigger is pressed, you let more fuel
in, when it is released, you let less fuel in.
The control handle is equipped with a throttle by means of which the user may decrease the engine
power. The throttle is not screwed in the control handle in the factory, it is placed in the bag with
accessories. For beginners we recommend screwing the throttle in to 1/3 of its range.
EXHAUST
Carbon monoxide (CO) is a side product of the petrol and petroleum-based
oil mixture in the combustion engine. Do not possible to neglect exposure
to even a small amount of CO as CO is released from the bloodstream very
slowly. CO enters the body through lungs and replaces oxygen in the blood-
stream. Physical activity increases the speed with which CO is absorbed in
the body. Potential CO poisoning victims should get rst aid immediately.
Use only the exhaust system installed by the manufacturer. Replacing of the required exhaust sys-
tem may result in the engine damage or engine output decrease. The damage caused by using of
another system will not be covered with the guarantee.
It is necessary for the users to ensure sucient cooling of the exhaust system during the operation.
It means that the motorized power board must be immersed in water. Running engine longer than
10 seconds outside of the water can result in damage which is not covered with the guarantee and
damage of the exhaust system and other engine components.
Even though the JetSurf™ engine produces much fewer side products during combustion than boat
engines, exhaust fumes are still generated when the engine is running. These fumes are released by
means of the exhaust system under the motorized power board where the carbon monoxide (CO)
emissions are produced. Therefore it is necessary to run the engine only when the power board is
on water as the fumes will dissolve faster and carbon monoxide resorption will be less probable.
Before every operation check whether the exhaust system has been installed completely and correctly.
Regularly check and clean the exhaust ending and its parts.

It is ABSOLUTELY NECESSARY for the rider to release the control han-
dle when he/she loses full control over the board or his/her balance. By
pulling the engine shut-o key from the engine shut-o switch you will
stop the engine immediately - FIGURE 1 and 2. NOT PULLING THE
ENGINE SHUT-OFF KEY FROM THE ENGINE SHUT-OFF SWITCH MAY RESULT
IN SERIOUS INJURY OR DEATH.
Always check it visually and test the connection of the control handle to
the throttle control cord by pulling the control handle in order to nd out
whether there are not any signs of movement.

DESCRIPTIONDESCRIPTION
IGNITION CONTROL UNIT (ICU)
Never try to remove the boot from the spark plug when the ignition con-
trol unit (ICU) is connected and in operation (indicator is lit or ashing).
You must never come in contact with the spark plug during the operati-
on or when the motorized power board is in water.
Never try to charge the ignition control unit (ICU) using another charger
dierent from the one specied by JetSurf™. This may result in which
permanent dam.
The motorized power board JetSurf™ is equipped with an ignition control
unit (ICU). DO NOT USE any other ignition control unit (ICU), than the one
specied and supplied by the manufacturer for the engine operation.
The internal battery situated in the ignition control unit (ICU) MUST BE CHARGED BEFORE EVERY
RIDE AND/OR DURING THE RIDES EXCEEDING THE TIME FOR WHICH THE BATTERY CAN STAY
CHARGED. It is necessary to take the motorized power board out of water, dry it out and make the
ignition control unit (ICU) accessible for charging.
Internal battery charging is described in detail in chapter RIDE on page 25 / Part A.
The electronic ignition system has six basic states:
– POWER OFF, – RIDE,
– POWER ON (ICU DIAGNOSTICS), – ENGINE CLEARING,
– IDLE (INITIAL STATE), – FAULT.
These states are signalised with a two-colour LED situated on the front of ICU between the conductor
bundles. The states and transitions between them are described in the graph XY.
These conditions are signalled by the indicator situated on the board next to the engine cover - FI-
GURE 1.
NOTICE
POWER OFF – ICU power off
By BRIEFLY placing your key to the ICU indicator
– FIGURE 1 – you will switch o the ICU. The
indicator is not lit or ashing.
ICU DIAGNOSTICS/POWER ON– ICU power on
By inserting the key in the switch on the handle –
FIGURE 2 – you will switch on the ICU control
unit which will perform a battery charge-up test
and switch on the electric bilge pump.
The LED is lit in red and then orange.
IDLE (INITIAL STATE) – water suction
If you remove the key after switching on the ICU,
the ICU will switch over to the IDLE state. If the ICU
remains in this state, water is sucked out of the in-
ternal area of JetSurf by means of the electric bilge
pump. The LED slowly ashes orange.
RIDE
If you place the key again to the switch, the ICU will
switch over to the RIDE state. The LED ashes green
in variable speed.
ENGINE CLEANING
– removing water or fuel from the engine
The ENGINE CLEANING state is activated whenever
the key is placed and left in the position of the circle reading “CLEANING/OFF” – FIGURE 1. Cleaning
is nished when you remove the key from the ICU. Instead of the key you can also use the magnet in the
paracord wristband – FIGURE 3.
This function is used to remove water or excess fuel from the engine or sucking fuel from the tank to the
carburettor. A detailed description can be found on page 38, part A.
The LED ashes fast in orange.
FAULT
All the faults are signalled with the LED ashing red.
If the key is removed, all the error codes are always signalled three times. If the key is in-
serted in the handle, the error code signalling is repeated until the key is removed.

PROCEDURE OF IDLE SETTING
Required tools: Allen key 2.5 (spanner No 8 for the back nut)
Note 1: Freewheel screw – position 1 – it is secured with a back nut from below. If you adjust
the freewheel, FIRST LOOSEN THIS NUT. When the freewheel has been set, retighten it.
The freewheel must be set at the operating speed of the engine (the engine should be running for
some time).
The screw for setting the freewheel revolutions (position 1) is set by the manufacturer in such
a way that the engine keeps running for a while by itself when started on land (without requiring any
throttle control).
If the engine stops by itself, it is necessary to tighten the freewheel screw (position 1) to the right
by half a turn. Tightening can be repeated as required.
If the engine revolutions are too high (it does not switch o in the freewheel), the freewheel screw has
to be loosened by turning to the left.
Note 2: When setting the freewheel, also check both extreme positions of the throttle shaft control.
Step 1: If the throttle trigger on the control handle is in the extreme position (pressed), the throttle
shaft control must be in position A – FIGURE 1. Step 2: If the throttle trigger is in the other extre-
me position (released), the throttle shaft control must be in position B – FIGURE 2.

CARBURETTOR
CARBURETTOR ADJUSTMENTS
Replacement or repair of any emission related component must
be executed in a manner that maintains emission levels within the
prescribed certication standards.
JetSurf motorized surfboards are certied to the United States En-
vironmental Protection Agency (EPA) as conforming to the require-
ments of the regulations for the control of air pollution from new watercraft engines. This certica-
tion is contingent on certain adjustments being set to factory standards. §1068.101(b)(1) prohibits
tampering, removal or rendering inoperative any device installed onto the engine in compliance
with EPA regulations prior to sale and delivery to, as well as after the sale to, the ultimate purchaser
of the product.
Dealers are not to modify the engine in any manner that would alter the horsepower or allow emi-
ssion levels to exceed their predetermined factory specications.
Tamper proof provisions: The carburetor is equipped with tamper proof screws – see below. For
changing the adjustment the special tool is required (custom design). There is also applied glue on
the screw to prevent adjustment by the pliers for example. When the glue is broken, it is a proof
of unauthorized settings.
IF THE CARBURETTOR SETTING IS INTERFERED WITH BY A PERSON
WITHOUT THE REQUIRED TECHNICAL KNOWLEDGE, IT CAN RESULT IN
POOR ENGINE OPERATION AND ITS DAMAGE. THIS DAMAGE IS NOT CO-
VERED BY THE WARRANTY.
The carburettor is a vital part of the
engine and it requires highly sophisti-
cated adjustments.
The carburettor has three basic adjusting
screws:
1 – A screw for adjusting the freewheel
revolutions (a freewheel screw)
2 – A screw of the freewheel jet L
3 – A screw of the main jet H
Screw adjustment – positions 2 and 3
are ALWAYS to be left to the seller.

Petrol is extremely inammable and highly explosive. Never smoke or
handle re within fty (50) feet / fteen (15) metres from the fuel area
when topping up fuel. Avoid spilling the fuel. If spilt, dry the fuel with
cloth and dispose of it on land. Never start the engine when you can
see or smell fuel as vapours can be more explosive than liquid fuel. If
fuel is seen during the operation, switch the engine o immediately and
seek assistance as soon as you get to land. Have the engine and the fuel
system repaired by an authorised JetSurf™ seller before restarting the
operation.
Fuel must always be transported only in canisters approved by the D.O.T.
organisation or CE (Europe). Transporting fuel in the fuel tank or in the
engine may result in damage or injury. Fuel vapours are even more
unstable, explosive and generally more dangerous than liquid fuel.
Never try to open the spark plug boot when the ignition control unit
(ICU) is connected and in operation (the LED must not be lit or ashing
on the ICU). The boot is under high voltage. A contact with it can result
in serious injury or death.
