If our JetSurf™ is ready (the chapter Before start), we can start using it. To check whether the engine
is working and warmed-up, rst try the device out of water.
THIS START OUT OF WATER MUST ALWAYS BE PERFORMED BEFORE EVERY RIDE!!!
JETSURF STARTING
Note: the starting process has two stages. Read these instructions carefully in order to understand
them completely.
STAGE ONE – ICU activation
1. Insert the engine shut-o key in the engine shut-o switch placed on the upper part of the control handle
for minimum 4 seconds (BUT LONGEST FOR 30 SECONDS!!!), then take the key out. The ignition control unit
(ICU) will switch on and also the other accessories (such as a bilge pump) will be activated. The control unit
activation is optically signalled by the control LED lighting and activation of the electric bilge pump which you
are able to hear (see the chapter Ignition control unit). At this moment, the JetSurf™ is prepared for start.
Note: The ICU will stay in this state for 5 minutes from the last time the engine shut-o key was
pulled out of the engine shut-o switch. Then it will switch o automatically and in order to start the
power board you will have to repeat this step.
STAGE TWO – engine start
2. Insert the key in the engine shut-o switch on the control handle for the second time. In the igni-
tion control unit (ICU), a three-second (3 s) delay has been programmed so that the rider could get
into a safe position and hold tight the grips of the motorized power board before the engine starts.
After this short delay, the engine starter will switch on and start the engine.
Note: The running engine can be switched o by pulling the key out of the engine shut-o switch.
WARNING: THE JETSURF STARTS REGARDLESS WHETHER THE THROTTLE IS PRESSED OR NOT.
THE JETSURF THEREFORE STARTS EVEN IF THE USER DOES NOT HOLD THE THROTTLE TRIGGER
ON THE HANDLE.
The Jetsurf is cooled with water and so it can run on land without the water
cooling only for a limited period of time. Otherwise it can get damaged.
Therefore do not leave it started longer than necessary. To warm up the en-
gine, it is enough to let it run for 3-5 seconds (BUT NO LONGER THAN 10 SEC-
ONDS as it can cause overheating of exhaust system and it‘s destruction.
TIP: To make the rst start easier, cover the
air intake of carburetor (diuser) with your hand
and in the same time accelerate. This will make
the mixture of fuel richer (this procedure replac-
es so called choke). With this procedure you can
also prevent knocking which can occur when you
are trying to start JetSurf™ after a long time. In
general, we recommend to use “choke” every-
time that you are trying to start JetSurf after
more than 12 hours.
BRIEF DESCRIPTION OF STARTING
1. STAGE- ICU activation
Inserting the engine shut-o key in the engine shut-o
switch for 5 seconds
You can hear the electric pump
Pulling the key out The ICU waits for 5 minutes for the key
to be inserted for the second time
2. STAGE - start
Inserting the engine shut-o key in the engine shut-o
switch
After 3 seconds the engine starts
independent of the throttle
During the time when the engine is running, check the engine operation both optically and acoustically.
Check whether the engine acceleration is correct and whether the freewheel has been adjusted cor-
rectly. If the freewheel revolutions are increasing, check the throttle cable line (adjust the freewheel, see
CARBURETTOR on page 50)
WARNING! If you are not sure how to set the carburettor, contact a sales representative.
WARNING! The correct engine operation is only checked on the engine when warmed up. After
the very rst start, the engine may run irregularly. In such a case repeat the start procedure once or
twice.
The rider prepared to use the JetSurf™ MUST WEAR a life jacket, safety helmet and MUST HAVE the
original JetSurf™ wrist band with the engine shut-o key attached to his/her wrist and it must be
connected with the motorized power board by means of the safety leash.
For sharp start from water it is necessary to nd a suitable place where to start riding. First it is nec-
essary to have a sucient depth from which we can start safely without damaging the bottom ns of
the vessel. The minimum depth is 50 cm. Keep in mind that after starting the engine, the rear part of
the board may sink by 10-20 cm.
Never start JetSurf™ in swimming areas. Also make sure that you have
sucient space for manoeuvring, mainly if you are a beginner. The ideal
area is 300x300 m without obstacles and with smooth water surface.
STARTING FROM THE BANK (IN SHALLOW WATER)
In order to speed up the process of starting, we recommend performing of the engine check and
warm-up (the rst start stage) on the bank and carrying the started power board to water within 5
minutes where the second stage of starting will be performed.
The following picture – FIGURE 1 shows the correct position of the rider when starting from
shallow water. The rider holds his/her JetSurf™ with both hands in such a way that with his/her more
dextrous hand he/she is able to hold the vessel and control the throttle trigger at the same time
– FIGURE 2. The rider IS STANDING next to the board, NOT LYING on the board. When
