I'm sure that you know this already but it's exactly the same as the DeWalt Powershop version except for some colours.
I had a DeWalt 1501 which is pretty similar to the 1601 - yours will have a longer arm - and always assumed that they badged these up for Elu. There was some cooperation for a while before DeWalt bought them.
My two snippets of advice are
1. to set the saw up with a sheet of 6mm MDF on the table. Set the depth so that you cut a mm or so into this sacrificial sheet.
Whenever you make a cut where it's important to minimise tearout on the back, just move the sheet sideways so that you get a fresh groove and best possible support for the bottom edges.
2. Use machine table wax on the column, it kept mine rust free for years.
Personally I think ripping on these is a disaster waiting to happen. Some people advocate it, I never got a good cut no matter how carefully I aligned everything first.
If you don't have a drill press, screwing a drill chuck into the back end of the spindle makes quite a useful horizontal drill in a pinch (blade and guard removed, motor turned 90 degrees)
The manual does give the sequence for adjusting all the support screws / clamping bolts to level and square the table to the column / arm. The column base is bolted tightly down to the pressed steel underframe and this is never adjusted, the table is always squared up to the column. The underframe isn't that rigid. Expect some sag at the extremities and either adjust it periodically or build the saw into a bench.
It was interesting to own, but I found the saw didn't deliver the very clean, precise cuts that I wanted from it. I replaced it with a good sliding mitre saw which does what I expect from it.
I will be happy if I can get the thing re-furbished and making basic cuts well enough
