|8| MAINTENANCE
Although JetSurf™ uses the highest quality materials available for production of the motorized power
board, the user has to perform regular maintenance which will ensure long-term life and high gloss
for which it was so sought after when purchased. Failure to observe these instructions may result in
the premature damage to the motorized power board which is not covered by the guarantee.
Always perform due maintenance of your motorized power board and be aware that its condition
may deteriorate with time and as a result of demanding operation or bad handling.
A basic precondition of good maintenance is observing of procedures described in the chapters
“AFTER THE RIDE” on page 68 and in the chapter “LONG-TERM STORAGE”.
SURFACE MAINTENANCE
Maintaining a top layer of quality wax on the surface of the motorised power board is crucial for
keeping of the original high gloss surface for years to come. Use only high quality wax, such as car-
nauba wax. Failure to protect this top layer can make the guarantee void.
MAINTENANCE OF TECHNICAL EQUIPMENT
Check the technical equipment of the engine compartment regularly in order to prevent bigger dam-
age to the power board. If any damage occurs on any part of the power board or if you are not sure
whether your power board is in order, please contact your authorised JetSurf™ sales representative.
ENGINE MAINTENANCE
The engine maintenance is described on page 68, chapter Long-term storage
SPARK PLUG
Use only the spark plug specied in this manual: NGK BPM 8Y, NGK BP7 HS for model RACE TITANIUM.
These spark plugs can be purchased online or in shops selling car parts.
Using any other type of a spark plug may result in the engine damage
and will make the guarantee void. Although some companies may claim
that they have an equivalent spark plug, JetSurf ™ strongly recommends
the customers to use only spark plugs of NGK brand. Using any spark
plugs other than NGK may lead to the engine damage and will make the
guarantee void.
MAINTENANCEMAINTENANCE
When installing a new spark plug, tighten it with a spanner according to
the instructions on the spark plug packaging.
After removing the boot from the spark plug, NEVER start the engine in a
standard way. If the engine is started without having the boot mounted
on the spark plug screwed in the engine, it may result in damaging of the
ignition control unit (ICU).
In order to ensure proper engine operation, the spark plug must be placed correctly between the
electrodes and it must be kept clean.
The spark plug must be checked before every ride and for a trouble-free power board operation it
must be replaced after 6 hours of operation.
CHECK OF THE SPARK PLUG:
When the spark plug is removed, you can check it visually. If the insulator is highly worn or if you can
see any scratches or cracks on it, replace the spark plug.
Using a shim gauge, you can measure the gap between the electrodes of the spark plug. For NGK
BPM 8Y and NGK BP7 HS for model RACE TITANIUM, this gap should be 0.7 – 0.8 mm.
SPARK PLUG REPLACEMENT
Warning – high voltage on the spark plug
boot.
Never remove the boot from the spark plug
when the ignition is switched on (signalling
LED must not be lit or ashing).
Do not remove the boot from the spark plug
if there is water in the engine compartment.
When working in the engine compartment,
it is BANNED to handle re.
For the operation of this combustion engine, it is ONLY allowed to use a spark plug NGK PM 8Y and
NGK BP7 HS for model RACE TITANIUM. In order to ensure proper engine operation, the spark plug
must have a correct gap between the electrodes and it must be clean.
