Genie TMZ 34/19 manual leveling issue

I've recently bought a 1999 Genie TMZ 34/19. It is the manual leveling type. I am having trouble with the left front outrigger. No matter what I do, I cannot get it to "read" level, even when the level bubble is perfectly centered. Of course, the controls won't function if the machine thinks it isn't level. The one time I did get it to work, it suddenly became "unlevel" with the bucket in the air. It's only the left front, the others are fine. What could cause this? I posted my issue last night, and haven't gotten any response. I've recently bought a 1999 Genie TMZ 34/19. It is the manual leveling type. I am having trouble with the left front outrigger.

If it's something simple, I would like to fix it myself. If it's major, I'll need to find a shop that will work on it. I have no idea if this is an easy fix or not. Any ideas are much appreciated! Is there an easy way to test them, explained in layman's terms? I haven't had this machine long, and obviously have never worked on it. Thank you! Rather than have two thread on the exact same question, I merged the original un-replied-to post into this one. digger242j
