Bosch 12" Dual - Bevel Compound Miter Saw with Upfront Controls and Laser Tracking 4212L - Answered Questions & Fixed issues
Electric brake stopped working
This can happen when the brushes get low, so check those first of all. They are at the back end of the motor, under the black end cap. If they are not worn low, then I would guess that it is a problem with an electronic module, but I am not 100% familiar with this model. Sometimes the module is clipped to the field coil, and some macines have it incorperated into the man switch or PCB.

Any guard blade for a
Yes, Did you buy it new? It has two heavy plastic seen through plate that
are attached to each other. This safety shield is gravity fed. That mean as one
pull down the saw the safety guard will pivot into the upper shield. As the saw
go back up after cutting a piece of wood. The safety shield will drop back into
it safety position covering the 12" blade. GB...stewbsion
Squeeeeekkkkks on start. Should I consider
If it were my saw I would use some WD40 on the motor armature for both ends of it.
A light spray and then turn by hand a dozen or so times to work it into the bearings.
Should be no problem to turn it on after that.
You can always add more, but it is difficult to take any away if you have added too much.
Have some paper towels around in the event the WD40 starts flying around a bit.
Looking for help scouts have a carpentry merit
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
Bearing replacement
Do you have a small bearing puller or a bearing splitter? On some I have had to crush the outer race and then clamp on the inner one and pull it that way. I have also used screwdrivers (GENTLY) to pry the bearing up a little so I could get it with something else. If you have a tool repair shop in your area, generally they would not charge that much to remove and reinstall the bearings for you.
Have an old Black and Decker 7321 Skill Saw.
With the saw UNPLUGGED, check around the base of the motor shaft, there should be some kind of button that you can depress to lock the blade from turning. Then with the appropriate sized wrench, turn the blade locking bolt clockwise (it is a backward thread) to loosen it. Then simply remove the washers, etc carefully and replace them the same way they came off. If there is no locking button, you can use a scrap piece of wood on the saw table and push down on the blade to lock it in place.
Bosch sliding miter saw,
Have you tried blowing out the mechanism with a compressed air nozzle? Frequently this friction is caused not by the bearing itself but instead by debris, sawdust, etc. built up inside the base of the saw. I'd give it a good cleaning to begin with.
If that doesn't work, try applying bearing lubricant directly to the bearing races.Use an extension straw if needed so you can get to them, as this is designed to penetrate where even the reliable old wd40 may not reach. You can find this a specialty woodworking stores, as well as some well-equiped home centers.
Let us know if this works, or you've already solved the problem...
