I just took the Might Press 15X15 out of the box and got it all set up. Its brand new...and I have no idea how to really use it. I had a swing press that broke last week. It says that it needs to be "locked" for the timer to work, but it doesn't tell me how to "lock" it. I tried to press a shirt and the transfer didn't take...I'm not sure if its the pressure or because I didn't lock it. Does anyone have one of these? Please help....my store is open and I can't press shirts...not good. Thanks in advance.
