I agree elmcannic, i’ve had a few issues in the past where levelling speed was set incorrectly and would time out on low oil timer on a relevel
More than once had I found that stupid F/S adjuster drift towards S when the three allen screws backed off just enough. Older valve as well as newer. Doing service work, who’d ever thought to check valve hardware? It’s like checking vic bolts…who does that? Until you’ve got a drip.
