Thank you, I’m in Italy.When the needle is that low you can move it up There is a little plate at the bottom of the gauge that moves back and forth, it will move the resting position of the needle up and down.

However if it's hard to move the needle over to High it may be out of calibration. I think sometimes the gauge gets hot somehow and gets out of calibration. If this is the case you probably need a new one.
I can fix these but it looks like you are Italy so it wouldn't be worth the shipping I think.
