    UPRIGHT SB60 problem erratic controls

    Hello Farmer, I'm sorry I never replied to your offer - I missed the notification and haven't been using this machine much so it hasn't made me angry for a while. Was acting up again so I'm back to thinking I need the Optimizer to go through the proportional settings. Just thought I'd check...

    Terex TB44 Manlift intermittent control problem

    Yes I've been able to get mine working, I still have a couple of things to repair but it is now functional which is great. I eventually got a hold of someone helpful at Terex, and although they were not able to help me they told me the name of a company that prints all of their manuals and I...

    Terex TB44 Manlift intermittent control problem

    Were you able to solve your problem? I'm having a similar problem with a Terex TB44, only I've inherited it after someone else has had a good go at trying to fix it first.
