the only reference I can find is on page 12 of the owners manual and that is the accuracy mode. If you have replaced the manual I would suggest going to "dewaltservicenet.com" and downloading the complete manual is 56 pages long but you can set your printer for the section that has the language you want. In the manual they use reference "M" for the 1/8" accuracy on grade. I hope this helps.
Hold down the ( V ) button while powering the unit on. THe puts the unit in cal mode for the Y axis. Hold down the up button while powering on the unit, this puts it in cal mode for the X axis. that is as far as I have gotten.
this unit does not have any replaceable parts, if the unis is covered by warranty, it would be exchange, if not then check with your local servicenter the max rate program to do so.
I assume that you are talking about the laser enhancing glasses if so the part number is 603367-00 and they list for 14.52 if not let me know and I will dig deeper.
Sounds like you figured this out on your own. I calibrate my own DW073 regularly without any fancy gadgets. I use the calibration check procedure in which the unit is placed about midway between fixed objects 100' apart.
These have a front and back and sides, so first you mark where the laser hits facing front to back at your targets. Then turn it 180 deg. relevel and resite. If the difference between the new and old marks is not the same then I turn the adjuster to halve the inconsistency and once that is accomplished, tweek the adjusting screw at the end of the level vial. (Because if you have adjusted more than the tiniest bit, the bubble will no longer display as level. So having established level, or closer to it, the adjustment here is actually to bring the relevant bubble vial back to level rather than assume they are level and adjust the physical beam mechanism (unlike the old physical sight levels where you adjusted the actual optics -- a little more like adjusting a rifle scope). Then you repeat for the side to side vial.
Anyway sounds like you are set so I posted this for anyone who happens to find this thread and is looking to field calibrate their DW073, e.g. don't have time or money to get it done in some shop.
I also wanted to post an add on question. Did you figure out how to adjust the "cone error", i.e. the accuracy of alignment of the twin lasers. They appear to have allen set screws that lock their adjustment, and maybe they are then reaimed by using a slotted screwdriver on the brass ring surrounding the laser. Maybe these are made eccentrically or slightly beveled so turning the laser reaims.
So far, my cone has stayed within the specs of 3/32" at 25' in the manual. But I'm seeing two lines at maybe 150' out. Probably that is close enough for gvmt. work, and I may find the adjusment so sensitive that I can't really get it any closer. But I'd at least be interested to know the method for adjusting the cone error.
