aerial lift

hi ya'll i've got a bil-jax lift with a problem. i was setting it up in a drive to do some repair work hit the auto level buttons for the outriggers it leveled out then came right back down. it did this three times carried it to a local shop they kept it two weeks trying it everyday and they could't get it to do it again now i'm scared to use it.next time i could be in the air.what would you do send back to bil-jax or use it?

I'd be nervous too, but I've had perfectly good and well behaved units just go bonkers while over 90'. Even if you send it back and it comes back cured, you won't know it they really fixed it, or just cleare it becasue it wouldn't act up again. Reminds my of a Kaw I had once that I took to the shop 2-3 times a day for weeks. I'd get there on two cylinders and when I turned in, it would just purr like kitten and never miss a beat while they drove it and ran tests. Then drop a cylinder within blocks when I left. Turned out to be a coil, btw.
