most information about controlling the Jetboard, maintenance and safety. It can not cover everything you will experience, but it will help you to
correctly use the Jetboard and protect yourself from potential dangers. The drawing section shows the individual components.

2、Safety Guide
2.1 Collision avoidance
The most common accident is a collision. Collisions cause more casualties than other accidents on the water, so practice your skills to
prevent collision accidents. The Jetboard doesn’t have a brake, you need to decrease the speed in advance before stopping. The Jetboard
can be steered at a very low speed,but you need to keep the engine running. A slow-moving deceleration will minimize the chance of
falling down from the board.
2.2 Precautions

2
Becoming familiar with the waterways and aware of people around you will help you to avoid accidents. Always keep a safe distance to
people, other boats and any obstacles around you. Remember, if you are on a collision course, you should slow down and make an appropriate
change in direction to avoid a collision.
2.3 Wearing a life vest
Always wear a certified life vest of proper size when you use the Jetboard. A life vest is the most important life saving insurance on the
water. A good life vest should fit properly, be rated for your weight and be bright in color. We also suggest that you wear some basic protective
clothing, such as a Neoprene(TM) swim suit, shoes and gloves to avoid orifice injuries.
2.4 Wearing a helmet
When a collision happens,a helmet can protect your head against impact trauma. But you will need to decide whether to wear a
helmet or not, helmets can also cause serious injury to your head at certain angles of impact. Please only use a helmet designed for water
sports.
2.5 Surfing at a controllable speed
When you use the Jetboard, Do not exceed the designed speed and keep it under positive control at all times. Loosing control of the board
can result in serious injuries. You should never use the Jetboard under the following circumstances: Being drunk or under the influence of

drugs, being exhausted or having problems to concentrate or keeping your balance.
2.6 Keep your Jetboard in good condition
Regular maintenance can keep your Jetboard in good condition. Check your Jetboard before every engine start. Do not overload it, remove
anything or do any modifications to the Jetboard, it will negatively change the performance.
Caution
1. Keep a safe speed and proper distance to people, property and other Jetboards.
2. Do not surf behind larger boats, as the wake can be very dangerous.
3. Do not surf closes to people or property, as the water jet can injure people.
