INFLATE
Insert the hose nozzle into the valve of the board and turn the attachment
clockwise. After inflation, remove the hose and close the safety cap of the
valve to seal it permanently.
CAUTION: If you expose the paddleboard to the hot sun, please check
the air pressure and release some air, otherwise the material could be
overstretched. The ambient temperature affects the internal pressure of
the chambers: a deviation of 1°C will result in a pressure deviation in the
chamber of +/-4 mBar (.06 PSI).
Please note: The valve is only airtight if it is closed with the valve cap. The
use of a compressor can damage your article, all warranty claims expire
when using a compressor.
