Dewalt Recent Questions, Troubleshooting Help & Support

check your regulator to see that 80 is what the gun is receiving and if it is move to 90 psi

What kind of batteries are they? If they are NiMh and haven't been used for a while, they can lose their charge and NOT be sble to be charged again!

Do you have a 3rd battery that does work? Buy a battery to make sure the charger is working or that the drill is working. If yes to both of these, then your old batteries are NFG.

I think that I have the same model, and yes, I do find the buttons to be of some trouble. In my experience, they can stick, not allowing the leg to collapse. I have to keep them pushed in at the same time collapsing the leg. Look for any burrs or bending on the folding device itself, as it may have gotten bent during a move and needs straightened.

The button is for changing the shoe position, you should find a lever on the opposite side that you need to lift up on to release the blade. You might be able to get a owners manual at Dewaltservicenet.com and in the middle of the page towards the bottom type in your model number and it will direct you how to download one.

circuit failure or broken contact

As far as a schematic goes, I would guess that it is proprietary in nature and that not even dewalt "repairs" them. I wouldn't be at all surprised if the same model had several different versions of circuit boards representing different production runs

You will need to ensure that you have power to switch and from switch. The motor not smoking does not mean it can't be bad

check battery. Check fuse.

Check fuses inside. Check fuse and connections in plug. If this is a 110v radio there is one on transformer winding.

If the red light is flashing rapidly it means that your charger has determined that your battery pack is in need of replacement and a safety circuit will not allow it to be charged. You may have an actual fault in the pack OR it may just mean that you have allowed the pack to discharge below the manufacturer's recommendations and the safety circuit has been fooled into thinking that the pack is defective. You need to decide which scenario is more likely correct. Using a DC voltmeter, determine if the battery pack has any voltage at all and which connections are positive and negative. If there is zero voltage, then you probably should go shopping and send your current battery to a recycler. If the battery pack does show some voltage, that is a good sign. TRY THIS AT YOUR OWN RISK! You can attempt to partially charge the battery pack (while not in the charger and not in the tool) by using test leads to connect it pos-to-pos and neg-to-neg to a fully charged battery of similar voltage/amperage. Only connect them together for a couple of minutes. Remove the leads and test with the DC voltmeter again to see if voltage in the questionable battery pack has increased by more than a volt or two. If so, it is still taking a charge. Move it back to its charger to see if there is now sufficient voltage to not trigger the safety circuit and allow it to charge normally. Wear eye protection. Don't cross leads. Don't try this on an obviously damaged battery or one that feels hot.

The box store pumps are usually sandborn pumps. I would find the model number and brand on the pump and go from there.

I'm assuming you have a DCD970 as DeWalt doesn't have a DC970 and the DW970 is an impact driver. The chuck on your drill is a new design that doesn't have a lock screw inside the chuck, they are put on very tight with lock-tite to hold them on. They are made to be taken off with a special chuck holder and vice jig that only service centers have. The allen wrench method used on older chucks won't work as the chuck will just loosen when you hit the allen wrench. I have on occasion removed one by doing the following: Turn the chuck fully open then secure it in a vice with the drill straight up. Holding the drill body and using the handle for leverage, turn the drill counterclockwise, as you are looking down on it, with steady, strong pressure. If the chuck breaks free it will spin off easily. If you are at all afraid you may break the handle you may have to take or send it to a service center to have it removed.

I would put it down to a faulty armature. Either the commutator needs truing on a lathe because its changing shape or else one or more of the armature coil connections have lost their connection because the solder has thrown off or they have broken from the commuter segments. All the best.

Try rearranging all the parts of the gun if possible. Clean them and try using them again , It should work.

You will have to get a new gasket. I had the same problem but I had drop my gun.

You have an answer in search of question. This site doesn't work that way.....

If you changed the, follow the directions that in the instructions that came with the unit, now they be loose so try this link. If the are worn replace them. https://www.youtube.com/watch?v=yPCvOeSFch4 '
