I have a Genesis and for the life of me I cannot figure out how to safely remove the translite. There's a hole at the top of the machine where it feels a tumbler/lock should be. I try to simply lift it by the bottom lip and it barely budges. I feel so silly asking this question, I know I've removed it before but I guess I just got lucky. There are no other locks or anything in the way and I do not see any alterations that would inhibit my progress. Any advice?
