A chainsaw without any fuel is just a very cool paperweight.
There's plenty of machinery down here; you might be able to 'borrow' some fuel from them.
Like the generator earlier, you'll need to find something that can suck fuel out of the machine. ?
Something like a hose.
It's about time the laundry room became useful - look for something that provides water.
?
It's connected to a big machine.
The hose going into the washing machine would do the trick, but it's firmly attached.
Do you have anything that could cut it loose?
Use the end cutters to disconnect the hose, and return to the drilling room.
On the far right, a gas tank is in plain view. Hopefully it's full!
Probably because the machine is still on - I'm glad aliens still follow important health and safety rules.
A control panel is on the left.
Pull the lever on the control panel, then open the gas tank.
Connect the hose to the tank, then attach the chainsaw to fill it up.
We have the extremely sharp tool needed - let's steal a hand!
