without cooling water, so please do not start the engine on the
shore for too long).
7、Precautions of using Jetboard
•Always wear life vest and explore the surfing area before start,
choose the appropriate waters to start. Note: Avoid floating debris
and underwater obstacles.
•Before use, check whether the engine screws are loose and whether
there is leakage in the fuel tank, fuel pipe, and carburetor. Otherwise
it will cause fire and explosion.
• Check the cooling water pipe before each use, ensure there is no air
leakage, blockage and damage. Otherwise, the engine and exhaust pipe will
be overheated and damaged.
•The engine must be started in a dry and well-ventilated place, and
it is strictly prohibited to start the engine indoor or a place with bad
ventilation.
•Long time running at idle speed may cause serious carbon build-up
on the spark plug. Never touch the running engine, there is risk of
pinching hand
•Before cooling down, Do not touch the cylinder and exhaust pipe
to avoid burns.
•If water got into the engine or engine sounds oddly, please do not
start the engine more than 3 times to avoid damages the engine.
Please check and eliminate the problem before starting again.
•Maintain a safe speed and keep safe distance from surrounding
people, objects, or other surf boats.

•Prepare in advance and avoid collisions. The Power Jetboard has
no brake. If you want to slow down and stop, you must be prepared
in advance.
•For your own safety, do not practice the jetboard too far from the
shore. Before you became a experienced surfer, don't surf too far
away.
8、Surfing Skill Quick Guide
•In Shallow Water: Put the Jetboard in the water with a depth of
more than 50cm, stand next to the Jetboard, put one knee on the
Jetboard and insert the key to stage 1(standby mode), hold the
handle on the hull and push the key to stage 2 to start the engine.
When the engine starts, give an appropriate acceleration according to
your weight, so the Jetboard is fast enough to carry the surfer, then
surfer can slowly try to standing up.
•In Deep Water: before go to deep water, please practice in shallow
water first. When you fall off in a deep water area or engine
suddenly stopped, don't immediately climb back to the Jetboard.
swimming to the broadside of Jetboard, hold the handle and insert
the start key. After the engine is started and fast enough to sliding,
the surfer shall climb on to the Jetboard asap, this can avoid too
much of water enters into cabin. Note: if the engine couldn't start
after 2-3 times attempts, please DO NOT start it again, or it could be
damage to the starting motor and other parts. At this stage, the
engine may have been flooded by the water, please go to the shore to

弥勒浩翔科技有限公司

clean the water.
Important note: After you familiar with the steering and throttle
control, you can try to adjust the CG (center of gravity) to achieve
better surfing experiences. When the front end is high, your CG is
too much back, slightly forward your body to move CG forward;
When your CG is forward, contacting surface of Jetboard to water is
too large, it will reduce the speed.
9、Common problem, Maintenance and Solutions
1、Gearbox oil replacement:
Every 15 hours the running or the oil can not be seen from
the observation window, the oil needs to be replaced and refilled
(0-W40 motor oil is recommended, and the oil level should not
exceed half of the observation window)
Follow the steps below:
1）1.Remove the red plug and screws on oil reservoir.
2）Put the red plug back after old oil is emptied.
3）Use a syringe to inject 50ml of motor oil from the top hole.
