Ok so I just got my new electric pick (Electric Li-ion pick gun) and was trying it out. I am an amateur at this so I'm probably making a simple mistake. I'm testing it out on a regular Masterlock #5 (something that I can SPP in seconds). It doesn't seem to work. I'm using light tension because I know that's a common mistake. I'm also making sure the needle is lined up with the pins.
So, my question is what am I doing wrong? Or more generally, what are some other common mistakes that people make when using electric picks? Thanks.
