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.
