DFI003/EN_part A
If the JetSurf™ is ready (the chapter Before start), you can start using it. To check whether the engine
is working and warmed-up, rst try the device out of water – BEFORE EVERY RIDE.
The JetSurf
TM
is cooled with water and can run on land without the water cool-
ing 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 engine, it is
enough to let it run for 3-5 seconds on (and BUT NO LONGER THAN 10 SEC-
ONDS as it can cause overheating of exhaust system and it‘s destruction).

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 con-
trol 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 indicator lighting and activation of
the electric bilge pump which you are able to hear (see the chapter Ignition control unit).
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.
WARNING: Start your Jetsurf without throttle (do not holt the throttle trigger on the handle.
STAGE TWO – engine start
2. Insert the key in the engine shut-o switch on the control handle a second time. In the ignition
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.
