How do I disconnect a green leisure gas bottle?

Turn the control lever from the vertical (on position) to the horizontal (off position). With your hand over the regulator, place your thumb against central spindle/shaft of control lever and press firmly towards the body of the regulator. This will release the locking collar from the cylinder valve and the regulator should spring away. The cylinder can then be removed for the replacement cylinder to be positioned.

Note: If the regulator of your appliance is different from the one described above, please email [email protected].
