I just bought a new Bosch 4100-09. The saw cuts great and was adjusted very well right on out of the box. However, when extending the table to the right it drops out of level and can be moved up and down with considerable movement. Has anyone else had this problem?

I’d be takin’ that puppy back to the seller. Not acceptable in my world.

what does the OM say about adjusting the table extension?

Nothing. There is no way to adjust it.

There is a way to adjust it; I actually did that to mine along with sliding the extension over to the left a bit.
On the underside, there are nuts you can loosen to adjust the height/position of the table. I laid a straight edge across the main table and simply adjusted the extension until it was even with the main table.

I don’t have mine anymore but I remember having to lock the right side extension.
It was a red lock. that will bring it to level and it would not move anymore.

Under the extension table on the inner faces of the rails.

Ian thank you but it is out of level locked. If I try leveling it and then locking it it still goes out. I should have been more clear in explaining the problem. The front right corner is close to level, mid way along parallel to where the saw blade would contact the work it is 3/32 plus out and by the time you get to the back right corner it is more.

I did not have that problem. I would take it back and exchange it.

What I did have in term of problem was that the top was not perfectly flat.
When I put a strait edge across I could see some ups and downs about 1/32
According to bosch that was within spec for this kind of saw. I lived with it since the cuts were square.

The other problem was that the aluminum fence was easy to bend.
I put a sacrificial fence on and clamped (maybe a little too tight )...

So Ian when you extended your table it stayed level to the rest of the top with no noticeable sag or play when locked?

I would have notice any sag with the straight edge across. I always do it on both diagonals.

The sawstop cabinet saw that replace the bosch had a sag and I had to shim the wing with aluminum foil.

Thanks, I checked out another new one and it was the same way. Maybe that’s all you can expect from a contractors saw. Front corner level, mid way 1/32 out back corner 1/16th out is the best I could get it.

I might try to do more adjusting like what Nite suggested, but for now it is cutting ok.

Have your say...
