Was using such a machine in the garage this afternoon, and was inspired to check its alignment. The azimuth is easy to set up; just loosen the screws, slew the saw to 90°, and tighten the screws again. As for the "leaning" function, that requires a pair of 10mm wrenches, a mattress to kneel on (to keep the work at eye level), and no small supply of patience. Tedious, but manageable My one real "gripe" with this saw must be that hot air from the motor is exhausted into the blade housing, such that dust is blown absolutely everywhere, making it a very "dirty" tool, and generally unsuitable for indoor use for this reason.

You have to be aware about precision of this digital protractor - it is not perfect and has an measuring errors. I verified similar device with angle standards and the error is bigger than I thought.

I have tje same problem. The guide rails on each side are not paralel. The upper parts of the rails are adjustable, but only sideways. If the lower parts where they are attached are bend or not in correct angle to the blade, I do not know how to adjust them. Any ideas?

Only the Danish can come up with such a crazy way to check an angle. Just make a full length cut on each side, turning the piece clockwise or counterclockwise. When you're done check the difference between the diagonals.

@@jacquesmertens3369 Incorrect The saw is fully adjustable with the screws on the front of the saw. They are sunken in in scale

I recently bought the simple version of this saw. I'm trying very hard to like it, but it may be going back. I find that it does not cut straight or smooth, and every cut is different. The blade seems to vibrate its way through the timber because there is too much flex in the aluminum body between the motor and the pivot point. Bosch tried a bit too hard to keep the weight of these saws down. My 15 year old simple little DeWalt (Elu) does not have this problem.

Yes, more weight could probably give a better saw. I wasn't entirely satisfied with mine at first either, I didn't think it could cut straight either. I do it by sawing a 2-5 mm. track when I pull the saw back and saw the rest when the saw is pushed forward, it gives a straight and nice cut, maybe something you can use.

I don't have that problem, try sending the saw for repair or the cancellation of the purchase if that is an option.

I received new one last week, and is out of square 1mm on 15cm cut. What a crap. Can not unscrew bolds which holdind that plastic underneath, to adjust it.

Grzegorz Sakan You cannot fix the fault yourself, no special tools are needed If there is a Bosch workshop near where you live, they can correct the error. Otherwise, you need to get hold of those who have sold it and demand it for the swap or take it back. It's terribly annoying, hope you find a solution.

On this saw you cannot adjust the fence because of the ridiculous design of it. Some people have found that the two halves don't quite line up and they have to adjust that by adding thin packers behind it. To adjust this saw to cut square you have to loosen the screws in the half moon angle scale and slip the lower (plastic) half that the turn table locks into. You then adjust the red pointer back to zero degrees.

What I don't get is all your off camera slight off hand style movements.
