Recently acquired a 3ph saw bench (Norsaw 1603) with 16" Trend tct
blade, 40
tooth I think.
Saw needed a little fettling. After a trial run I removed blade and
delivered to sawdoctor for sharpening.
Whilst this was being done I set the saw up to my satisfaction.
Replaced the blade and tried it. Blade runs true as far as I can tell.
Cuts
well enough but 2 immediate problems.
1) Sawn edge of timber is scorched on both sides. Have tried this with
various timbers from 10 to 125mm.
2) On pushing timber through the blade the far end tends to lift from the
bench. Not a good thing.
Both these problems were evident when I first got the saw and tried it.

A riving knife is fitted and all timber is well seasoned/dry.
I can only think that the blade has a bump or something but there is
nothing
visible.

Any thoughts please?

The blade must be exactly parallel to the table slot otherwise the teeth
on the exit side of the blade will rub on on side or other of the cut
made by the front (cutting) teeth

Usually this is set by loosening the table and tapping until a dti
registers the same from front to back of the blade body.

Final test can be done by cutting a narrow strip of wood clamped to the
mitre gauge and listing to the blade it passes the back of the blade.
You should hear a very slight noise. No noise almost certainly means it
tilted away from the cut and would burn on that side if you were rip
cutting. Lots of noise and it will be burning the end of the test piece.
Note that is the arbour bearing is worn, any attempt at setting will fail.
Fix this first.
