2. SAFETY AND PRECAUTIONS
DUOTONE STRONGLY RECOMMENDS::
If you are not yet able to foil wing foiling or if you feel insecure, you must attend a licensed school to
learn the basics of this fantastic sport. Get familiar with the safety precautions, which are indispens-
able for safe foil wing foiling.
Foil wing foiling creates a heavy strain on your body. You should only go foil wing foiling if you are
in good physical condition and suffer from no medical conditions that may prevent you from wing
foiling. Always act carefully to not endanger yourself or anyone else. Do not endanger the safety of
uninvolved third parties! Be aware of the risks you take and limit them to a minimum level!
Before going on the water make sure you are familiar with your DUOTONE equipment. For your own
safety, read the following instructions as well as product descriptions very carefully.
2.1. FOIL WING SAFETY
- Only use on unobstructed stretches of water.
- Only fly the Foil Wing if you are a good swimmer and you are wearing a life jacket.
- Use a leash equipped with a quick-release system so that you can completely detach yourself from
the Foil Wing in an emergency.
- Avoid power lines, telephone lines, airports, roads, buildings and trees.
- If you are using a board with a board leash, you must wear a helmet! Be aware of the general risks
associated with water sports, such as stones and rocks, waves, sunburn, hypothermia, jellyfish,
etc.

2.2. DANGERS FROM THE FOIL WING
WHEN FOIL WING FOILING YOU MIGHT FACE THE EXTREME FORCES OF THE ELEMENTS.
In rare cases the Foil Wing can cause dangerous situations:
- You can hurt yourself through uncontrolled water take-offs caused by gusty conditions, and
the danger of collision with obstacles.
- Risk of injury due to an inability to control the Foil Wing in gusty conditions.
- Use a leash that allows you to keep the Foil Wing under control.
- When not in use, inflated wing must be secured with sand or heavy objects. A wing filled with air
can fly away at any time, injuring people and in extreme cases even kill them.

DUOTONE UNIT 23 / UNIT 23 MANUAL
2.3. DANGERS FROM THE BOARD OR FOILBOARD
The use of a hydrofoil board is a high-risk activity and can be extremely dangerous if implemented
incorrectly. This can result in serious injury or even death for the user or other individuals in the vici-
nity. All users of the DUOTONE Foil Wing must be aware of the associated risks. These include loss
of control, collision with the board and even drowning. Some of the foil components are extremely
sharp and thus pose a potential risk. To protect the rider and others against injury, the foil must be
handled with special care from the point at which it is constructed until it is used. We recommend
using a certified helmet at all times and an appropriate collision-proof or protective vest as well as
a wetsuit and neoprene shoes. Do not exceed your capabilities and maintain control over the Foil
Board and the Foil Wing at all times. Do not push beyond your limits when using the Foil Wing, and
ride at a speed that is commensurate with your ability level. Be aware of your surroundings, and
familiarise yourself with them. Do not endanger others by coming too close to swimmers, boats, jet-
ties and other objects that could be damaged by you or the foil. Do not use the foil in shallow waters.
This could also result in injury to you and damage to your foil. You should also be aware that indivi-
dual components on this product are exposed to natural forces and may be subject to wear.
2.4. DANGERS TO UNINVOLVED THIRD PARTIES
- It is within your responsibility to check whether uninvolved people or other athletes may be
endangered or injured by your actions or your gear.
- Do not foil wing foiling at places where uninvolved third parties might get injured.
- Avoid flying the foil wing in the vicinity of other water users such as swimmers, kayakers, wind-
surfers, water-skiers and boaters.
2.5. WEATHER RELATED DANGERS
- Avoid offshore wind.
- Be careful with onshore wind.
- Get information on tidal and sea current conditions at your spot!
- Get information from both the weather report and the locals on prevailing weather conditions.
- Never use the foil wing with wind forces so strong that you are unable to maintain precise control.
- Do not use the foil wing when wind conditions are likely to change dramatically.
- Never use this foil wing when thunderstorms are nearby or when such storms have a good chance
of developing (check the weather report!).
- Leave the water immediately when a storm is approaching. You are in a life threatening situation
since you may be struck by lightning!

6. Connect the leash with the Foil Wing using the loop
provided at the front tube.
3.3. Securing the FOIL WING on the Beach
When the foil wing is not in use it has to be secured so it won’t fly away.
1. Lay the foil wing down in areas without any sharp objects.
2. Turn the foil wing around so that the leading edge lies on the ground and points into the wind.
3. Attach the leash to a fixed object, like a pole, tree or alternatively weigh the foil wing down with
sand or any other soft and heavy object.
5. Close the valve
4. Close the outlet valve on the strut and tip and pump the
foil wing according to the label next to the valve (see
Section 4 on using the Air Port valve). Do not exceed the
maximum pressure specified for your foil wing as this can
result in damage to the wing. Reduce the pressure by 0.5
- 1 PSI for more comfort.

pump hose, including the blue ring clockwise by approximately 90˚. Excessive overturning of the
valve may cause internal damage to the valve system. The arrow markers on the disc and the
adapter of the pump indicate how far you should turn.
4. Pump up the foil wing NOTE: Due to the manufacturing tolerances of the pump hose (in particular
third-party pumps), some air might escape from the valve while pumping. This however does not
effect the inflation of the foil wing.
5. After inflation, turn the end of the hose (and the blue ring) approximately 90˚counterclockwise.
This will activate the non-return function of the valve.
6. Remove the end of the hose from the blue ring.
7. To achieve an airtight seal, screw the valve cap onto the thread. Take note to place the valve cap
correctly onto the thread for accurate fastening and sealing.

FOIL WING CARE
6. FOIL WING CARE
- Avoid bringing the foil wing into contact with sharp-edged rocks, thorns, wood and other objects
that may damage, puncture or tear the cloth.
- Do not expose the foil wing to excessive sun as it ages the material unnecessarily.
- Deflate the bladders if the foil wing is to be left unattended for any length of time.
- Avoid leaving your foil wing on the beach for extended lengths of time as small wind movements
may quickly cause wear and tear to the cloth.
- Try to pack up the foil wing without cuttlings into the bag to avoid tearing the canopy.
- To carry a foil wing, turn it so that the leading edge is upwind and the underside faces upwards.
Grab the centre of the leading edge tube. If the wind is blowing, it will hold the foil wing clear of the
ground. Be sure not to drag the tips of the foil wing across the ground.
- A coating that results from using the foil wing in salt water will not damage the foil wing. However,
rinsing in fresh water and drying doesn’t hurt.
- When cleaning the foil wing be sure that no water, dirt, or sand gets inside the bladders.
- Be sure that the foil wing has dried completely before packing it up. Otherwise changes of color or
mildew could occur. Such bleeding is not covered under the DUOTONE warranty.
- Do not dry the foil wing in direct sun!
- Keep sand and water out of the air pump.
