    I have the same problem but mine was imported brand new from America via a postal address i had to set up. The problem with mine is it fires but most ov the time doesnt fire a nail the pin misses the nail then stays out? Must be a fault with the lining up ov the nails? The touble is i can send it back now as Dewalt dont ship direct to uk.

    so when you plug in the battery does the headlight come on and remain steady (no flashing) and the motor run but the tool wont actuate?

    also, check the driver blade to see if it's down or up

I have both the DC616 and 618 and have used them sucessfully for about three years. Two main things go wrong. There is a drive belt that breaks (drives the spool that give the energy to drive in the nails), second are two small rubber bands on either side of the drive head that break. The bands can be accessed by taking off the front silver cover, the drive belt is access by spliting the case. Make sure you are using the correct nails or the drive pin may become bent and will jamb repeatedly. Hope that helps!

    I hope I answered your question. I assumed you checked to see if there was a nail jambed in the nose peice. If there was the motor won't run and the lights will just flash. If the motor does run and no fire then my answer should help.

    I am having a little different problem, first it has not been used very much and I have not tryied until now to fix it. the unit is a Reconditioned one.
    there appears to be no jamming or bent rod. I have the face off and the bands look good.
    I pull the trigger and the light stays on for 10 sec. with no blinking
    When I depress the nose the light blinks once and a gear moves ever so slightly, the one with the 2 bands.
    No fan turns on just the blink light and tiny **** movement.

Have you put any oil or wd40 into the gun. i did this just to clean the gun up a bit and ruined. went to get it fixed and they said these machines run on friction so any lubricant is a no no. do not rty and maintain these guns with any lubricants. cost was about $300 to fix so i just got another one.

If there is a nail jambed between the firing pin and nailers that would do it If you've already checked that try oiling it or the firing pin it'self could be broken. Also most (not all) of the battery operated nail guns require an air cartrige to force the firing pin down I don't know about the dewalts because paslode is my brand but it is very small and sometimes it is hard to find.

If the motor runs and stays running when you depress the nose then the problem is in either the trigger switch or the solenoid.
If the motor runs for a moment and shuts off with the light blinking I would check your battery. These are very temper mental with voltage, and even if your battery just came off the charger & might work in a drill, it may not have 18v to supply the electronics.
Please note - these are not easy tools to work on, I would recommend bringing it to a qualified repair shop near you.

I have a dewalt dc618 finish nailer When I go to shoot the lights on the gun start to flash and will not shoot ?

Continuous flashing indicates low battery charge or poor battery connection. If lights flash 4 or 5 times indicates possible control module fault.

It will not fire the nails. Unit is cleared with no obstructions. This has happened several times but now it will not work

If your gun is over a year old, you may have failing orings. Dewalt used vinyl orings (yellow to gold in color instead of black rubber) in the gun that fail. The vinyl orings are installed around the cylinder and inside the trigger valve. The gun may not leak air, however will not fire. The repair kit has all necessary orings, however may not include the trigger valve. Good luck

You have to take the front part of the case off, and you will see the problem. Either the drive belt is broken or the rubber band like springs have broken. Happened to both of mine after about 2 years of use. I ordered the parts through Dewalt and they have some nice diagrams showing the locations and how things go together. Not too hard to do

My DC618 nailer won't fire .

Check the battey then take it out and check the driving rod. On the front of the gun, flip the latch and make sure it is pushed all the way back.
