REMOVING THE FIN
Unscrew the screw from the square nut. Slide the fin and then the square
nut out of the rail using the screw. Reattach the screw and square nut to
the fin immediately.
DEFLATION
Gently press on the valve core needle to slowly release pressure from the
board. If after about 10 seconds the air pressure of the board has dropped
a little, push the valve needle completely down and turn it clockwise to lock
it in the „open" position. When releasing the air, please make sure that
there is no sand or dirt around the valve or getting inside.
