Is my clit pump locked?

I just ordered a new Size Matters clit pump but the trigger won't squeeze at all; is there some kind of lock I'm supposed to release before using it?

Thanks!

I don't have this so I can't offer any practical advice but it might be worth asking customer care on live chat :)

Thank you NatandTom, great suggestion! I used the Live Chat for help and they explained to me what to do (I say they because it seemed to be an individual and their manager). For those out there that encounter this issue in the future, what you do is:

-turn the back handle around clockwise so it's looking up

-pull it down a bit, it might seem like it's going to break but I pulled it down almost 90 degrees without breaking it

-turn it back around (to starting position) and it should now squeeze

Happy orgasms!
