Automatic closure AVS
The closure is opened prior to the filling procedure by single-hand operation of the lever and is held in its open position by catching the lever in at the side. The closure opens automatically when the hose is connected.
Once the filling process is finished the hose is detached and the relevant line blocked so that it is gas- and odour-tight.
For the option “theft safety” an oval-shaped ring made of high-grade steel is used. This one is additionally inserted. It is sticked over the lever at the side and passed through the locking mechanism. Now a padlock is used. In this locked state the lever can be moved slightly, but the top is completely closed. Neither fuel can be pumped out nor can harmful chemicals be supplied to the storage.
Here is a video that shows how to connect the hose:
