Thats well ****. I’d return it if you can, but might as well check the inner mount for it see if something is amiss in there. The rise and fall blade support runs in a track, a simple bar inside presses against it.(those 2 bolts) fix it in place. Could be that they’ve either been drilled wrongly, or something has moved.See if you ,by loosening off the 2 bolts and see if you can move the pressure bar running against it.
If it helps, this one is a copy of the older record power RPBS 10″ saw. Same guides, cut depth etc etc, and if it helps I took that entire upper guide assembly off a fair while ago as it increases the depth of cut, from 120mm to 165mm,I left the rise and fall mechanism in place, but if i take that off too, I can further increase it to 185mm. It wont mean the blade slips off the wheel, the lower guide does more there and I did that as i needed to deep rip some maple and didnt fancy using my saw bench for the double cut method, given its 80mm each, and a 1 1/2kw 10″ spinny blade, unguarded and buried deep in the timber. It was simpler and safer to increase the bandsaw depth of cut.
With the upper guides removed I’ve not had a problem since, even cutting to the max depth in hard and soft woods. I use a 3tpi rip blade.
I like the extending table on that saw, its a good feature and a better fence and support. . It looks like the only difference is the RP has a cast table to this alloy one.
I’d say its a good basic saw and well worth the money.
