Question about Bosch 12" Dual - Bevel Compound Miter Saw with Upfront Controls and Laser Tracking 4212L

Mitre saw won't cut square

I have a 15 year old craftsman mitre squuare. it works like a mule but when I use it to cut a compound angle I can not get it to cut regular mitres square. When I cut a mitre the bottom of the angle is open. I have tried to zero out the saw but it seems that zero in dicator must be mis alined. Any help would be greatly appreciated.

Look on top of fence
see 4 holes
loosen 4 bolts (probably hex wrench) and fence will loosen also
framing square against loose fence and lowered blade (to re-calibrate)
tighten fence,... square to blade

You will have to use a regular square to check out the crafstsman and find out where it is wrong.

How to square up my saw and where I get a copy of the manual


With the saw unplugged manually pull the blade guard fully open and use a strong elastic band/string or otherwise wedge it open to give yourself full access to the blade.

Use an engineers square or at a push a good carpenters combination square measure the angel between the blade and the saw bed. you might find it's slightly off 90 degrees.

Ok, depending on the make of saw there will be a screw thread at the front or rear of the blade on on or close to the pivot points (where the bed tilts to allow different angles to be cut). it usually has a loking nut. Slacken off the locking nut and also slightly slacken off the tilt adjusting screws. You should be able to easily move the bed in relation to the blade. You will see the bed hitting the bottom of the adjusting screw.

Gently turn the screw and keep measureing the angle with the square. Make sure that the squares blade is tight to the saw blade and not touching the small tooth at the edge of the blade. there should be absolutely no gap either on the saw blade or saw bed when its correct.

Holding the screw with one tool getly tightedn up the locking nut ensuring that the main screw does not move.

CHeck everything again and tighten up the tilt mechanism.

Let me know with pictures if you need more exact info for your saw model and I can point out the parts.

Looking for help scouts have a carpentry merit badge from the 50s they talk about using a BEVEl and a Miter tools can you help


The bevel is an angle fiding tool. it consists of a wooden section about 4" long with a swivel bolt at one end connected to a slotted metal blade (similar to a 1 foot steel ruler). The bolt has a wing nut and bolt to allow loosenig to allow the blade to rotate and slide to the required angle where it is locked into position using the wing nut.
The mitre is a wooden block with slots cut into it at pre determined angles. ie 45 degrees. When cutting a mitre joint the wood is placed against the block and the saw follows the line of the slot cutting the 45 degree angle.
Hope this makes sense and good luck

The vertical blade stop is not true vertical. What adjustments are there to adjust the stop?


If you look on the back of the saw where the pivot is, there should be a bolt on either side that should adjust how much bevel there is . As for a 90 degree angle, there should be a locking pin or stop to keep it from leaning out of square. Be sure that it is accepting the pin properly and that it is clean. Not sure if there is an adjustment on the sliding saw, but i know there wasn't on my dual compound mitre saw

I have 1 10 In compound miter hexbolt will not loosen and lock will not hold. Is it possible that the bolt is a left thread?


most mitre saw bolts that hold blade are left hand thread. If you overtightened you might have to use extra force to loosen, on occasion I have had to use an impact wrench to loosen.
