   I'm assuming it's along the edge of the board he's ripping. Are they burn marks? Is his blade warped?

   Measure it with a micrometer, mark it with chalk, cut it with an ax.

   not burn marks, they are blade marks (actual kerf marks in the wood).  He used both the blade that came with the saw as well as his Forrest WW II with a stabilizer.

   Hmm, I'm gonna have to think about this one...Is the wood moving side-to-side during the rip?
   Is he pausing during the rip?
   Is the blade perpendicular to the table?
   What about run-out?
   Are the fence and blade parallel to the miter slot?Mark

   Things to check.

   Arbor for runout. Blade for runout(sharp quality blade?). Blade/arbor parallel to miter slots. Fence adjusted away from blade 1/64" or so (the back teeth should have couple thousands clearance). Splitter installed and properly adjusted (shouldn't be pushing the work away from the fence). Technique (pushsticks help control).

   Oh yeah, and check if he is overtightening the arbor nut. Good and snug, not impact wrench kung-fu grip tight. Blade spins opposite threading, it ain't coming off.

   All I can think of.

   Had the same problem with my 40 years old sears table saw, the back barring locked up , so it let the motor pull the arbor shaft out of line. Plus the bolts holding the undercarriage was loose, so that it was not square with the miter grooves, check that out with digital calipers.  After ordering parts to repair the saw I have a saw that cuts true, and talk about the blade singing, ware ear plug every time I turn the saw on now!  $250.00 repair and I fixed it with a grease fitting, so no more bearings going out again,  and grease fittings on the up-down shaft too.

   Can't afford to be without the table saw, I custom build furniture full time.

   Tell him to call the 800# on the owners manual (Orion). They're all over customer service; at least they were for my bent fence.
