20 Most Recent Dewalt DW082 Laser Plumb Bob Questions & Answers

Inside the laser is a small piece of silver paper(self adhesive) this is what the 'out of level' encoder uses to tell the laser when it is level. Is would have come off. You will need to open the laser and re-attach it to the bottom of the pendulum. There is an obvious place for it

Well, I opened a DW077 today as it didn't wanted to turn on. It was brought to me by a neighbor and he hadn't a clue what made it stop working. I removed the outside screws and rubber feet using a Torx T10 with a hole in the middle. Be careful not to remove the screws arranged in a square pattern as these hold the steppers in place. You don't want to mess with calibration ! Also be gentle with the rubber around the rotating head. You need to remove the metal ring on the outside to detach the rubber grommet.. Once open, there is not much to be found inside. There is one pcb, two steppers and some other plastic stuff. Measuring over the big cap indicated 0.9v and over the small cap I had a unstable low voltage. After desoldering some wires, the underside of the PCB can be inspected (all components are on the underside). What I found there was that the main capacitor (1000µF 50v 105°C) of the 5v voltage regulator circuit was blown and leaking electrolyte. Not only was the capacitor gone, it also took an SI4532A mosfet array with it. The 3A fast chip fuse was still intact. The circuit pulled +- 10mA at rest and it went up to 20ma when depressing the power button. That SI4532A chip consists of a P and N mosfet in an SOIC 8pin package. The N side had a hole and the pins were blackened. My guess is that this controls the power on-power off signal that goes to the LM2596-5 buck regulator. I have made some pictures of the damage. So this is a route to research. Hope it helps someone

Lasers do not bend, per se. If you have some sort of distortion of the beam, then the reflector is faulty or damaged. If the beam is slanted then the gimble assembly is not hanging straight.

In either case these are throw away units. Go back to the retailer and see if they have a solution. Or call Black and Decker and see if they will replace it for you.

clean it if its not in a long time otherwise it can be a problem by a fall Was perhaps fallen during a transport? and therefore is little or slightly bent. inspect it.

Are there spareparts in US for this DW087 ? In Europe there are spareparts for to get ! Its for Milwaukee in Europe that there are little Milwaukee tools where nothing is to get but in australia all parts and may be in the states to. All based on marketing technical decisions and differences.

What model laser is it

Same exact features, buttons and functions as this manual by Irwin.

I want to use an old sensor forgiven during 30 years. I have no more manual, off course. Thanks for your answer
