My bosch DAF220 digital miter finder is stuck and I cannot clear the angle as the manual describes. Is there a way to reset the tool?

Adjusting the miter angle involves two cast surfaces sliding against each other. If those surfaces have some irregularities, high spots on the two surfaces will bind against each other. You may have to disassemble the rotating table from the base and do some filing or grinding.

Open the the moveable arm and make it straight (180 degrees) or in line with the other.Take the screw off of the black cover at the elbow (1 screw). Lift from the round part and lift off. Then loosen the two screw just inside the cover. This will allow the flywheel to spin and you should now get a read out. If the flywheel does not spin then you need to replace that piece. Gently tighten the two screws and put the cover back on. Hope this helps!

It is a wire that has come off inside the black case

The manual states this tool needs no calibration. I spoke to the service rep at Bosch, and he confirmed there's not 'published' way to do it. There are a number of outside firms that will do it. If you call Bosch support and explain the problem, they should send you a mailing label and calibrate it properly. Depending on if it's in warranty or not, there may be a fee for calibration and the return shipping.

There is an electronic component that is defective and it draws a lot of current (more than the normal rating) this makes the batteries over heat, if it's new ask for replacement of the tool.

Cheers!

cut 4 pieces of 2x2 to1.5 inches short of 2 metres. lay them out end to end to form a two metre box. it can only work one way. then take string from corner to corner to find the center, making a crosshair. then stand a level rod at the centre to the desired height and fasten equal length lines from each corner to the peak. using a compound mitre saw, place an angle finder at the bottom and top corners to give you the angle to cut your piece with the saw set at 45 degrees, to give you your compound miter for the top. just set the saw blade to line up with the angle finder to get the bottom cut. the length of your "tight" string line frome corner to peak is your length of "hip" piece

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

I was trying to reset the zero on my angle finder. It's a Powerfist Digital Angle Finder, the same as the Skil 2100.

After turning the unit on, if I press the Miter and Hold button together and hold them, the unit goes into 'calibration' mode. (The display flashes 0.0). If you do nothing, it will always stay in this mode forever after that.

You can then reset your unit - it takes time however and patience.

With the aid of a large protractor, draw angles on a large sheet of paper (I used a couple of 11 X 17" pages) from 0 degrees all the way up to 220 degrees.

Turn on your angle finder and make sure the numbers are flashing 0.0. This will be your 0 degree reading. Hold the finder closed and press the Hold button once.

The display will now read 10 degrees. Open up the finder until it matches your 10 degree marks on your paper and press the Hold button again.

The display will now read 20 degrees. Open up the finder until it matches your 20 degree marks and press the Hold button again.

Continue setting your angles in this fashion up 'til you reach 220 degrees. The next button press will close the calibration cycle and the numbers will stop flashing.

Your unit is re-calibrated. Now, if it's off - you've only yourself to blame.

Good luck!
