The Drunken Lizard Pub

Thank you. I've already solved it by moving one inch further so I could reach all handles simultaneously. In place of running around This was actually the major problem as - generally speaking - walking in this game is...

Actually I have a question "from the same region"
To the right from the entrance to the cave there is a strange device with 6 handles. There is also a door visible in the utmost right bottom corner of the cave.
Has anybody figured out how this 6-handles device works?
