KSGER T12 soldering station

I just bought one on eBay, I have seen a couple posts on here about them.

I already know I need to ground the case, and there's a resistor I need to remove because mine has the lithium clock battery, but what else do I need to do to make this thing safe?

Here's some pictures I took, it would not let me attach to the original post.
