[@PowerPaul:] No, you can't run away... The best thing is: have two weapons in your hands and smash them... Every weapon has different damage. So the axe is a nice tool for that (but will damage the game machine more, too - you will discover what happens when the game machine gets to damaged...) or the metal hammer. The crowbar is good, too. All these tools are in the tool box right from the machine. (Can be tricky to grab them since 2 or 3 version updated. Just try several times...). In general I would recommend one short & one long "weapon"/hammer/tool - one left, one right. How they work (also in combination with W/A/S/D you can test on the puppet which is hanging from the roof...)

There is a specific range how far your weapons can interact.
