Dewalt dw073 This works great when its dark or cloudy but as soon as the sun shines it does`nt work at all. Any advice?

Depends on power requirement. My whole house uses approx 4 kW to run air con and rest of the house power. 19 x 350 solar panels generates 1 kw to 6.5 kw per hour through a 6 kw inverter.
The variance comes from the sun is not always out, or behind clouds and the panels don't face east and west to capture the morning and evening sun.
They are mono crystal which generate about 1 to 1.6 Kw in cloudy conditions.

As I am on the power grid the excess power is feed back to the power company who pay me 6c per k/w that I feed in during sunny days and then charge me 26c per k/w in peak times when it is dark !
Today I got 40 kw/h generated for the day which with feed in tariff is $2.60 as it was sunny. . I could run the air con on 10 kw/h from the power company in the dark , if the a/c used 2 kw I could run it for 5 hours for free.
Where you run into problem is that on a cloudy day you might get 1 k/w per hour . This is not a problem if you use mains power from a power line supplier as it suppliments any short fall. If you are on a no grid connected system you may need to consider Battery Storage as well to charge up when the sun is out and then it supplements the power to your house when it is cloudy or dark.
The solar panels would need to generate enough power to run the house and to charge up the battery system if used.
Batteries have a limited life of 10 years and usually use lithium Phosphate batteries . You tube has many videos on battery systems and off grid solar setups. However batteries are a changing technology with Electric Vehicles becoming more common.

Go to the Dewalt service site at http://servicenet.dewalt.com/ and search for your model in the Find Parts box. You'll be presented with several accessories that have model numbers starting with DW073. Select your model number and under downloads you'll be able to view or download the parts breakdown and instruction manual.

Could be first signs of algae growth.
Check the chlorine levels.
Check the pH levels.

A good place to start with Dewalt tools is the switch. Take the front off the handle and pull the switch out far enough to test the posts on the back. Plug the cord in and check for voltage where the cord attaches to the switch. No voltage, bad cord, replace the cord. If you have voltage, the cord is good. With some help, hold the switch on and check for current on the motor side of the switch. If no voltage, replace the switch. If there is voltage there, you are going to have to check the brushes, armature and/or field for continuity or shorts.

hi, try this...save to your computer and then open. good luck, those are nice but a bit tricky to get set up!

Hi,
On your laptop there is an Fn (function) key and another button showing the image of sun. Keep Fn pressed and then click the "sun" button to increase the brightness of your screen.

look where you fuction keys are is ther a symbol like a sun with up/down arrows on it.if so press up arrow to brighten or use Fn and the up arrow key together.

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.

Thanks,

Brian

Sounds like speakers are going bad. I had a set that got wet and they worked sometimes, didn't work other times. Sounds like the bigger issue is why they're getting wet. I'd check to see if rain, etc. is getting down into the door somehow.
