USER MANUAL
Copyright 2016; All rights reserved
JetSurf™ motorized power boards were designed and manufactured by MotosurfWC and Formula 1 en-
gineers to push the limits of motor sports. The power boards created by JetSurf™ are the only motorized
water vehicles with the ability to be transported by hand, car, boat or plane (as hand luggage on interna-
tional/domestic carrier ights). This allows the users of JetSurf™ power boards to travel easily around the
word – a unique attribute in comparison to other motorized watercraft.
JetSurf™ parts and components are manufactured by MSR Engines, based in the Czech Republic.
Thecompany specializes in the development of combustion engines and specialized electronics.
JetSurf™ power boards are produced in a single factory that uses the highest standards of production
technology. Only the nest materials and components currently produced in the European Union are
utilized. This comprehensive in-house production allows JetSurf™ to ensure themaximum precision and
ecient production..
JetSurf™ power boards were developed with exceptional eort to minimize environmental impact.
Through specialized and the most advanced technology, engineers have reduced the total weight of the
JetSurf™ power board and accessories to forty point eight (40.8) pounds (eighteen and a half kilograms
[+18.5]). JetSurf™ power boards meet homologation (registration for racing) standards for noise emis-
sions, as well as using an internal combustion engine that enforces the Greentech technology and com-
plies with the emission limits set for motor vessels. The complete drive unit is certied and approved by
the European Commission and received the European Union label, CE. All this eort toward compliance
with international standards has ensured that the power boards are also compliant with North American
requirements for personal watercraft.
The information contained in this User Manual represents the most up-to-date product data available at
the time of printing. Because JetSurf™ is committed to continuous product improvements and advance-
ment of technology, the company reserves the right to change the product, components, specications
or other aspects of the JetSurf™ motorized power board without advance notice or a requirement to
equip previously produced JetSurf™motorized power boards with these changes. You can nd current
upgrades on the JetSurf™ websites (www.jetsurf.com). Check this website regularly.
This User Manual for Owners or Operators (hereafter referred to as the “User Manual”) cannot anticipate
every circumstance involved in owning or operating the motorized power board. JetSurf™ strongly en-
courages owners and operators to regularly review the U.S. Coast Guard website (www.uscg.mil) or the
relevant coast guard and/or authority regulating the laws pertaining to the use of personal watercraft
with particular attention to information provided for personal watercraft. Also check JetSurf™ company’s
website (www.jetsurf.com) for updates and product information.
JetSurf™ provides the following information in the expectation of long and enjoyable ownership of this
JetSurf™ motorized power board.
This manual will help you to operate your vessel safely and easily. It contains a detailed description
of the vessel, its supplied or built-in accessories, systems and information about their operation and
maintenance. Please read it carefully and learn about the vessel before you start using it.
Do not set out on a ride until the conditions (wind force and wave height) correspond to the con-
struction category of your vessel and make sure you are able to safely control the vessel in these
conditions.
This user manual does not include detailed maintenance or repair instructions. If you experience any
problems, contact the manufacturer of the vessel or its representative. If you have the maintenance
manual, please follow it during the vessel maintenance.
Maintenance, xing and adjustments of the vessel can only be made by trained and qualied per-
sons. Any adjustments which might aect the safety characteristics of the vessel have to be checked,
implemented and documented by a competent person. The manufacturer of the vessel cannot be
held responsible for any adjustments not approved by it.
In some countries it is required to have qualication or certicate to control a vessel or some other
special regulations might apply.
Always duly maintain your motorized power board and be aware it will wear with time and as a result
of demanding operation or bad handling.
Each vessel, regardless how hard-wearing it is, can suer severe damage if used incorrectly. This is
incompatible with its safe use. Always adapt the speed and course of the vessel to the conditions
(wind force and wave height).
The person controlling the vessel must use suitable swimming aids described in the chapter PER-
SONAL SWIMMING AIDS in this manual. It is necessary to point out that in some countries the law
requires wearing swimming aids under all circumstances while using the JetSurf™ and is therefore
necessary to comply with these national legislations.
PLEASE KEEP THIS MANUAL AT A SAFE PLACE AND HAND IT OVER TO A NEW OWNER IF YOU
SELL THE VESSEL.

SAFETY MATTERSSAFETY MATTERS
DEFINITION
“Power board” or “motorized surfboard,” interchangeable terms in this Owner’s Manual, mean a ves-
sel that uses an inboard gasoline-and-oil-powered engine, providing power to a water-jet pump as its
primary source of propulsion power. It is designed to be operated by a person (“rider” or “operator”)
sitting, standing or kneeling on the vessel. Direction of JetSurf™ is controlled by rider leaning to one
side or another, speed is controlled by throttle trigger located on the handle.
GENERAL COMMON SENSE
It is the responsibility of the owner and/or operator to comply with safety-related material
provided in this Owner’s Manual and to regularly review safety information provided by go-
vernmental agencies and local jurisdictions. Common sense should guide owners/operators
at all times, regardless of whether the engine is running or not. Failure to do so will result in
serious injury or death.
Riders are reminded that general common sense should be the rule for any and all outings. While
some objects appear above water and are easily avoidable, it may be necessary to pay special atten-
tion to underwater objects as well.
In using the power board, some common sense considerations are for safety of the rider and other
vessel riders, boaters and passengers, while common sense also is necessary to preserve the power
board in good shape.
JetSurf™ cannot anticipate every type of activity or negligent performance that could result in death/
injury or damage. The operator accepts responsibility for use of the power board in a safe and
sensible manner. Particular attention must be paid to surroundings at all times to avoid accidents.
Care must also be taken to avoid situations in which carbon monoxide fumes may become trapped
between objects or may be released out-of-the-water. Be certain to read the information regarding
carbon monoxide poisoning contained in this section of the Owner’s Manual.
With regard to damage to the power board, riders should avoid running it all the way to shore. Often,
beaches or shoreline are made up of rocks and/or sand that can scratch or dent the power board.
Such occurrences are not covered under the JetSurf™ Limited Warranty statement, which appears
later in this Owner’s Manual.
Familiarity with the nautical waters in which the power board will be operated is extremely important.
Currents, especially strong ones, can aect the performance of the power board and threaten the
safety of the operator. Pay attention to buoys and other markers also.
It is critical for all owners and operators to be prepared to maintain and operate the power board in
a responsible and common sense manner at all times.
All riders must use helmet, life vest and a safety leash at all times while operating JetSurf™ to prevent
any serious injury or death in the events of accident (you can nd more details in CLOTHING category).
|2|SAFETY MATTERS
BEFORE USING THE POWER BOARD THE FIRST TIME, READ THIS ENTIRE OWNER’S
MANUAL.
If any of the information is not clearly understood, contact the retail sales dealer for clarication and
further understanding prior to operating the power board. Safety is the primary concern of Jet-Surf™,
and it needs to be for all owners and operators as well.
The Safety information provided in this Owner’s Manual cannot anticipate every circumstance that
may arise while maintaining and operating the power board. Basic safety information is provided
and it is not all-inclusive. JetSurf™ strongly encourages all owners and operators to regularly review
the U.S. Coast Guard safety information (www.uscg.mil and www.uscgboating.org)* and other safe-
ty-minded, watercraft websites and authorities which apply to the relevant area/region under which
the JetSurf™ power board is to be operated.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards.
Obey all safety messages that follow the symbol to avoid possible injury or death.
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
NOTICE is used to address practices not related to physical injury.
This information could result in damages to the product that are
not covered under warranty.
These precaution icons will appear throughout the Owner’s Manual.

ENGINE PREPARATION
Operation of the power board engine out of the water for more than
ten (10) seconds can result in permanent damage to the engine and ex-
haust system, (temperatures of cylinder shouldn’t be higher than 65 °C/
149°F). Such damage is not covered under the warranty.
Touching any part of a running engine, in particular any component that
is moving, can result in serious injury or death. If it is necessary to ac-
cess or touch an engine for any reason, the engine must be turned o.
EEngine also become increasingly hot with usage and can result in skin
burns if engine is not allowed to cool prior to touching it.
Never transport fuel except in D.O.T. (USA) or CE (Europe) -approved con-
tainers.
Transporting fuel in the engine or fuel tank can result in damage to Jet-
Surf™ or injury to people handling the board. Fumes from fuel are even
more volatile, explosive and generally dangerous than liquid fuel. Never
transport JetSurf™ power board with fuel in its tank. JetSurf™ transport
is described in detail in the chapter “TRANSPORT” page 66.
Later in this Owner’s Manual are instructions for the proper preparation and maintenance of the
power board’s engine. Be sure to read and follow these instructions.
Note also that operators should regularly verify that the engine is probably installed and rmly axed
to the engine housing. DO NOT attempt to start an engine that is not secure!
Operators and bystanders should NEVER touch any part of a running engine.
Avoid allowing any object, even small bio-degradable items (seaweed, sand, small animals...) to come
into contact with the engine. This could result in damage to the engine that would not be covered
under warranty.
Use only JetSurf™-approved replacement parts. Using any other parts will void the warranty and may
adversely aect the operation and safety of the power board.
When starting the engine, ensure that individuals (especially children) are at least 33 feet/10 meters away.
The engine was designed and crafted for the JetSurf™ retail power board only. Never use
the engine for any other craft, object, projectile, or item. Such usage is expressly prohibited.
CARBON MONOXIDE
Carbon monoxide (CO) is a gas and it can be extremely dicult to de-
tect, because it has no color, taste or odor and it can accumulate without
awareness. Exposure can be fatal in a matter of minutes. The eects of
CO are cumulative and repeated exposure to low amounts can have a
similar eect to a single high concentration exposure. Carbon monoxide
should be avoided, while any exposure should be treated immediately.
The exhaust on the power board is purposely located at the stern (rear) of the board. While emis-
sions from the engine are relatively low due to its purpose-built design which ventilates into the water
under normal operation, there are still some CO fumes as a natural by-product of a combustion
engine. Therefore, riders must operate the power board as designed. No one should ever be towed
behind the power board while it is in operation. The engine should not be operated when the power
board is out of the water (this can cause damage to the engine from over-heating also).
CO enters through the lungs and blocks oxygen. Milder symptoms of poisoning include headache,
nausea, itching or irritated eyes and dizziness. Victims often become increasingly weak and disorient-
ed. These symptoms should not be confused with alcohol intoxication.
Individuals who suer from lung- or heart-related issues may be aected more quickly. Alcohol and
tobacco use also accelerate symptoms. For all riders, regardless of health or ingestion, note that
physical activity will also hasten CO absorption.
In the even that someone shows evidence of CO poisoning, immediately shut o motorized surf-
board or any other combustion-engine in the area. Provide fresh air, if possible, and move the victim
to an area away from the CO concentration. Provide rst aid and seek professional medical assis-
tance immediately.

LAW ENFORCEMENT
When underway, operators may be required to cease manoeuvres and allow U.S. Coast Guard* or
state law enforcement personnel to come alongside. Some Countries, States and jurisdictions may
require a minimum age to operate the power board, pass a training course, and/or possess an op-
erator’s license. Requirements vary widely. If operating in a location that allows minors, such activity
should be done only under adult supervision.
Be sure to check annually regarding requirements for legal and safe operation of the power board.
UNDER THE INFLUENCE
Under no circumstances should a power board rider ever operate under the inuence of alcohol
or drugs, including prescription drugs that have potentially disorienting side eects. This can be as
dangerous as driving a car while under the inuence!
REGISTRATION
In many jurisdictions, it will not be necessary to register the power board with the state of principal
use. However, because the power board is motorized, registration may be necessary. Verify with the
state and local law enforcement entities in the area in which the power board will be used most prior
to using for the rst time.
SPEEDING/NOISE
Some areas have restrictions regarding speed related to creating waves and maximal noise restric-
tions. Operators of power boards are required to adhere to these requirements.
ELECTRONIC DEVICES
Operating the power board requires full attention. JetSurf™ strongly recommends leaving cell phones
(including waterproof models), radios, iPods, and other devices ashore during outings. The distrac-
tions can potentially lead to accidents.
CLOTHING
Persons in range of the power board’s engine moving parts should exercise caution to
avoid having clothing or hair come in contact. If clothing or hair become entangled in mov-
ing parts, injury may result.
Because the engine has moving parts, owners/operators should never wear loose clothing when the
engine is in operation. Straps, buckles, as well as the edges of cloth can become entangled in JetSurf™
moving parts.
If the owner/operator has long hair, it should be tied up or secured in some fashion so that the hair
cannot become entangled in the engine’s moving JetSurf™.
An injury can occur nearby the jets as a result of water inux into the body cavities. Conventional
swimwear does not protect suciently against water being forced into rectum or vagina. All the riders
must wear at least the bottom part of the neoprene suit or any other garment providing the same
protection. We recommend wearing footwear, gloves and glasses.
Helmets are a compulsory item of safety gear and must be worn at all times while riding. It is expected
that operators will, from time to time, fall o the power board, even in normal operation. Helmets
provide protection in the event the operator’s head would strike the board. Helmets are therefore a
mandatory accessory and should be manufactured to wear on the water, t properly and be relatively
lightweight. JetSurf™ makes no claims nor promises regarding protection, including that aorded by
helmets.
The use of an arm or leg leash is compulsory and must be used at all times while using JetSurf™.
PERSONAL FLOTATION DEVICES (PDFs)
It is the responsibility of the owner/operator to comply with any and all laws, statutes and requirements
for personal safety. American federal law requires the wearing of a U.S. Coast Guard-approved* person-
al otation device (PDF) under most circumstances. State and local laws and statutes may also vary
from federal requirements.
As JetSurf™ power boards are commonly dened as personal water craft it is essential for all users to
check with their relevant local Authorities for all information relating to the use of safety accessories.
JetSurf™ takes no responsibility for failure of users to comply with the relevant laws which apply to
the use of personal water craft in any specic location.
Authorized JetSurf™ dealers are able to assist owners and operators in ensuring that they are prop-
erly outtted for conditions and to comply with the law of the countries where JetSurf™ is used.

OTHER SAFETY MATTERS
Riders should:
- Be at least sixteen (16) years old or the minimum age required within the jurisdiction in which the
power board is operated. The power board was designed to be operated by adults.
- Wear appropriate safety gear especially a Helmet and Life Vest and safety leash.
- Ensure the power board is in excellent condition and ready to operate in top form. Have sucient
fuel for the outing or gear the outing to the generally expected period of time that fuel will remain,
and be sure that the ignition battery is functional and well-charged to avoid becoming stranded away
from shore.
- Avoid operation during bad weather, including but not limited to, high winds, rain that obscures
vision, warnings of impending threatening weather, high waves, or any weather in which the rider
feels at all uncomfortable.
- Avoid operation in water that is too shallow or is brackish. Because the power board engine is wa-
ter-jet pump propelled, weeds and other ora can foul the engine intake. If it is suspected that fouling
agents or small objects have been brought into the pump/engine system (height of water stream
coming out of engine cooling system nozzle output will get smaller or end completely), immediately
cease operation and perform a typical maintenance operation to clean the system.
- Maintain a speed and operational method that ensures
the rider can avoid collisions with objects (above and below
the waterline), buoys, docks, shorelines and other vessels.
- Know and practice navigational rules and regulations.
- Maintain an unobstructed view at all times, particularly in
the direction the power board is moving.
- Ride singularly on the power board. Multiple people on
one power board can overload it and cause it to sink.
The power board is built with anticipation of one (1) aver-
age-sized person per board.
- Never exceed the highest loading capacity.
- In addition, it is necessary for the rider to maintain line-
of-sight, which means there should never be another per-
son in front of the rider as the outing progresses.
- Not carry aboard any item. The power board requires
the rider to maintain control via the control handle. The
rider should never be distracted from control of the pow-
er board.
- Always keep the magnetic key with kill switch Paracord
around the wrist so that when the rider goes overboard
the engine will be immediately shut down.
REPORTING ACCIDENTS AND INSURANCE
Federal law requires reporting of accidents in which:
- A person dies;
- A person disappears from the vessel in what appears to be a situation that could have resulted in
death or serious injury;
- A person disappears from the vessel in what appears to be a situation that could have resulted in
death or serious injury;
- Damage to vessel and/or property that exceeds the amount stipulated by law. The total may be
lower in some jurisdictions and it is the responsibility of the owner/operator to verify;
- The power board is destroyed.
Any instance in which other vessels or persons appear in distress, power board operators are re-
quired by law to oer assistance unless doing so would result in potential danger to the power board
operator. Good Samaritan protection is provided to anyone who oers good faith assistance.
Even when others operate the power board, the owner is generally responsible for damages or
injuries that may occur. Owners must not allow any Third Party to operate the JetSurf™ without prior
instruction in correct use and operational risks. Owners are strongly encouraged to carry sucient
liability and property insurance to provide in anticipation of potential judgments in those instances.
Theft and on-shore damage are additional reasons to purchase insurance.
REFUSE AND POLLUTION
The U.S. Coast Guard* and/or relevant Authority which applies to the region where the JetSurf™ is
used provides detailed information regarding the disposal or refuse. In general, refuse, even bio-de-
gradable, should be disposed properly on-shore. If the user deduces that there are any substances
that could pollute waters leaking from the board, it should be presented to an authorised JetSurf™
dealer for repair. Pollution laws and regulations are stringent in most areas.
At no time should the power board owner and/or operator alter the engine exhaust system or fuel
system in any fashion. Doing so is both illegal and potentially dangerous.

WARNING

18 19
When overtaking, you are the give-way vessel. The other vessel is expected to maintain course and
speed. Avoid it as you clear it. When being passed by another vessel, maintain speed and direction
so that the passing vessel can clear.
In other circumstances, when preparing to go around a bend on a body of water, sound a prolonged
blast on a whistle for four (4) to six (6) seconds. Regardless of whether you hear a response, proceed
with caution.
Under normal operation situations, stationary shing and sailing boats (stationary or moving) are
given the right of way.
Always learn about and pay attention to buoys and other markers. The Uniform State Waterway
Marker System has been devised for interior waterways in the United States. Markings may vary by
geographic location. Always consult appropriate authorities before using the power board in unfa-
miliar waters.
SAFE OPERATION ON THE WATER
Laws, rules, regulations and enforcement have been developed in North America and around the
world to ensure safe and proper operation of all watercraft. It is the responsibility of the owner and/
or operator to familiarize himself or herself with all applicable ordinances on the body of water upon
which the JetSurf™ power board will be operated. For operators in the United States, refer to the
website*: www.uscg.boating.org
In Canada, refer to the website**: www.tc.gc.ca/eng/marinesafety/menu.htm
Other countries have their own laws or participate in international rules. Always verify markings and
rules as they apply to any body of water on which operations will be conducted.
GENERAL PRUDENTIAL RULE
Rule 2 in the International Rules says, “In obeying and construing these rules due regard shall be
had to all dangers of navigation and collision, and to any special circumstances, which may
render a departure from the above rules necessary in order to avoid immediate danger.”
GENERAL EXPECTATIONS
Always use common sense when encountering other vessels. The power board is considered a pow-
ered watercraft and will be expected to give-way to non-powered vessels that have less manoeuvra-
bility. The vessel that does not has the duty to take proper and timely action to sta out of the way of
the stand-on vessel. Normally, the give-way vessel should not cross in front of the stand-on vessel.
Always move in such a way that the stand-on operator can see the operation.
When encountering other powered vessels, there are three (3) main situations that could require
avoiding a collision:
- Meeting (approaching another vessel head on);
- Crossing (travelling across the other vessel’s path);
- Overtaking (passing or being passed by another vessel).
When meeting another vessel head on with the risk of collision, neither has right of way. Both vessels
must alter course to avoid an accident. Keep the other vessel on the port (left) side unless it is possi-
ble to clear each other by maintaining course.
When two (2) power-driven vessels cross paths with risk of collision, the vessel that views the crossing
vessel to the starboard (right) side must give way.
MEETING
When two boats are approaching
each other on the water, one has
the righta-way and is designated the
“stand-on” vessel. The other boat
must yield or give way and is desig-
nated the “give-way” vessel.
In illustration A, you are the JetSurf™
in the center. You are required to
yield to any vessel shown in the
white area (you are the “give-way”
vessel). Any vessels shown in the
shaded area must yield to you(you
are the “stand-on” vessel). If both
of you are heading directly toward
one another, illustration B, you both
must give way. You should turn right
to keep the approaching vessel to
your left or port side. This rule does
not apply if both vessels will be clear
of each other if you continue on
your set course and speed.

OVERTAKING
If you are passing another vessel, you are the “give-way” vessel.
The other vessel is expected to maintain its course and speed and you are required to stay
out of its way until you are clear of it. If another vessel is passing you, you should maintain
your course and speed so that the overtaking vessel can steer safely around you.
CROSSING
If you and another vessel are
crossing paths close enough to risk
a collision and the other vessel is
on your right (starboard) side, you
must yield or stay out of its way.
If the other vessel is on your left
(port) side, you must maintain your
course and speed, as long as the
other vessel yields the right-a-way
to you, as it is required.

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 oper-
ation. 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 on surface 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 immedi-
ately and nd assistance as soon as you get to land. Have the engine and
the fuel system repaired by an authorised JetSurf™ seller before restart-
ing the operation.
FUEL TANK
Use lead-free car petrol with the octane
number 95 or higher mixed in the pro-
portion 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 cannot be
covered with the guarantee.
Fuel system consists of the fuel tank, a fuel
lter (can be 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.
In the newer models, the fuel tank can be removed easily by releasing clips (couplings) in the fuel
route which are situated near the carburettor. (See the instructions specied below in the user man-
ual 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 rac-
ing 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.
– 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

4) Move the tank out upwards – FIGURE 4.
FUEL TOP-UP
Observe all the safety instructions specied in this manual.
NEVER add fuel into the tank which is inside the JetSurf™. Before adding
fuel, ALWAYS take the tank out.
FUEL MIXING
Make sure that petrol and oil are mixed properly in the correct propor-
tion. If the proportion is not observed, the engine may get damaged.
FUEL TANK REMOVAL
Observe all the safety instructions specied in this manual.
1) Disconnect the rst CPC coupling connecting the tube coming out of the tank and the blue tube
going into the snorkel – FIGURE 1. The CPC coupling has a security clip which must be pressed
when disconnected.
2) Disconnect the second CPC coupling connecting the tube coming out of the tank to the tube going
to the carburettor – FIGURE 2. The CPC coupling has a security clip which must be pressed when
disconnected.

CONTROL HANDLE
The engine shut-o key must be at-
tached 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 move-
ment 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.
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 comprises of:
- Engine shut-o switch (marked 1);
- Throttle trigger (marked 2);
- Engine shut-o key (marked 3);
- Connector to the ICU (marked 4); and
- Throttle cable (marked 5).
The engine shut-o key must be attached safely around the rider’s wrist using a paracord wristband
on the hand in which the rider holds the handle. If the key is pulled out of the engine shut-o switch
(e.g. when the rider falls from the board), the engine will stop immediately. It protects the rider as well
as any other riders/vessels in the surroundings.
As specied above, the throttle trigger is situated on the handle, at the end of the throttle cable. JetSurf™ rec-
ommends controlling the throttle with your index nger. You can control the throttle cable by means of the
throttle trigger. When the throttle trigger is pressed, you let more fuel in, when it is released, you let less fuel in.

EXHAUST
Carbon monoxide (CO) is a side
product of the petrol and petrole-
um-based oil mixture in the com-
bustion engine. It is not possible to
neglect exposure to even a small
amount of CO as CO is released from
the bloodstream very slowly. CO en-
ters the body through lungs and re-
places oxygen in the bloodstream.
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 re-
quired exhaust system 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.
Besides that 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 en-
gine 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.

It is ABSOLUTELY NECESSARY for the rider to release the control handle
when he/she loses full control over the board or his/her balance. By pull-
ing 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 SERI-
OUS INJURY OR DEATH.
JetSurf™ strongly recommends keeping the throttle cable so long that no
loops, folds or kinks could be formed on it. The throttle cable should be
curved gently in the “S” shape in order to prevent damage to electrical
contacts of the throttle cable all the time. Shortening of the throttle cable
cord may result in failure of the mechanism of automatic switch-o and
lead to serious injury or death.
The point in which the control handle cord is connected to the throttle
cable cord should not be changed or moved - FIGURE 3 and 4. If the
knot is moved in such a way that the angle under which the control handle
is used gets changed signicantly, it can inuence the normal use of the
control handle and it 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.

IGNITION CONTROL UNIT (ICU)
Never try to remove the boot from the
spark plug when the ignition control
unit (ICU) is connected and in operation
(LED diode is o and is not ashing).
Never try to charge the ignition control
unit (ICU) using another charger dier-
ent from the one specied by JetSurf™.
Permanent damage is not covered by
the guarantee.
NEVER leave the engine shut-o key inside engine shut-o switch longer than 30 seconds
if you are not going to continue in your ride. Leaving the engine shut-o key inside handle
for longer period of time (ie over night or when transporting the board) can lead to com-
plete discharge and non-reversible damage to batteries.
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.
You must never come in contact with the spark plug during the operation or when the motorized
power board is in water.
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 ig-
nition control unit (ICU) accessible for charging. ONLY use the charger supplied by the manufacturer.
Using of a dierent charger may result in permanent damage which is not covered by the guarantee.
Electronic control elements are divided into three (3) parts:
– Ignition control unit (ICU) with internal batteries;
– Ignition coil;
– Engine starter.
