There's a thread over on UKW about this router becoming difficult to height adjust. I happened to need to use my table mounted one the other day and I'd quite forgotten what a dismal dispiriting experience it is trying to finely or even coarsely adjust the height once the Triton has been used a bit.
I've tried cleaning out the teeth and cogs but the design is fundamentally a very weak one IMO and I would never buy another Triton. I see I posted a thread about it back in 2014 and on reflection never managed to satisfactorily repair it - hence why I hardly ever use it.
