To turn it, get in it at the shed on the turntable and simple turn left or right as if you were steering a truck!

Thanks. the problem i had was it wouldn't seat all the way down.. i kinda just forced it down eventually. the turning works really well.. the placeable base is great, however some may have issues on maps with low laying ground.. first place i put it the bowl ended up filling with water. kinda looked cool.
