We have a Genie Z45/25 that worked well however now the main boom has started to drift down fairly quick (5' in 30 seconds) A few people mentioned it may be counterbalance valves on the two cylinders?? Any ideas? Thanks!
Hey, doesn't look like anyone replied to your comment at all, just thought I'd touch base and see if you corrected the problem or not, did you try replacement of the cb valve? Or test it? The cylinder its self should have a load lock valve on it as well that could be failing, or a piston seal internally could be compromised/damaged allowing fluid to bypass internally.
