thats about 138 bar, a wee bit low, take it back. edited to say i have a reg and a bottle key in the back of the motor, always check my bottles before i leave the yard.
Spoke to them on the phone, they were very apologetic and offered to swap it out. In the end we did a deal - half full, half price. Suits me as I don't have to spend another 2 hours replacing it.
