You are supposed to use a service tool which pulls the motor to a certain tension. I have had this problem in the past and have had to replace the blade carier to solve the problem. The part is around 60.00 I think now. it loses it's friction where it meets the drive wheel, as a result it is not thrown downn onto the brad with as much force.

DEWalt clipped head framing nailer. Model DY51825TY1 will not fire

while I have to say I am not a dewalt guy, I can try to point you in the right direction, assuming there are no leaks, then you state the trigger is not engaging , could be three things, one the trip ( safety) or the trigger valve or the trigger its self, if you feel comfortable pound out the pit that holds the trigger in. Just the trigger not the valve, then activate air to the gun, press the trigger, if it fires its the trip or the trigger rocker switch. the trigger can be examined see if its damaged bent or cracked, see if the safety trip is out of adjust, if it doesn't fire it could be the valve spring inside the trigger valve is broken.
don't worry just watch how it comes apart and remember you cant make it worse. it doesn't fire now. anything is an improvement

I have a DC608 cordless nailer that will not fire the driver the driver does not move at all but everything else seems to be functioning properly Thanks Tim


You can go to this webpage and download the owner's manual which gives instructions:
You can also download a parts diagram and order parts here.

I looked through the manual and found that DeWalt's Brad Nailer does not require tools to remove jammed nails from the nose piece. I believe this is the problem with your nailer, unless it's empty. Some of these nailers will not fire if there's less than 6 nails in them.
Another feature on this nailer is the trip lock. It is a safety feature that prevents accidental firing. Any time you adjustments made to the nailer will automatically turn the trip lock to lock position. You'll find this lock on the right side, under the Dewalt label.

The instruction manual will explain all this.

Hope this helps. If it does, I would appreciate a vote. Thanks,

The gun dose not fire the pin all the way in ?

Dewalt list the obvious causes below.
Remember that the gun may not facilitate the use on specific materials that are just too much for the gun to handle. The most common cause for this issue is depth adjustment is not set properly. Also make sure that the nails being used are the correct nails for the gun. Its possible to buy the wrong type and they look very similar to the ones needed.

Here is The website addy for Dewalts pdf user manual and tech tips.

Low battery charge or damaged battery Charge or replace battery
Depth adjustment set too shallow Rotate depth adjustment wheel to a deeper setting
Tool not firmly applied to workpiece See instruction manual
Material and fastener length Choose appropriate material or fastener length
too rigorous an application
Damaged or worn driver blade tip Replace driver/return assembly; see authorized service center
Damaged or worn driver/return assembly

The finishing nails don't drive home all the way,around 10mm proud of the timber sticking out!

I am not familiar with that particular nailer but on most there is an adjustment screw or "barrel" nut that allows you to adjust the depth of the driver. If this has rattled loose as is often the case, the nail heads will be left sticking up. If that doesn't solve the problem, there is the chance that something internal has come lose and is inside the ram - preventing it from driving down all the way. If this is the case then it can destroy the inside of the tool and will need to be torn apart to be repaired. IF you are to repair it yourself I would suggest going to Dewalt's web site and see if you can get an exploded view of how it comes apart. As you take it apart take pictures of your progress so you can look at them when reassembling it. I did this recently with a Bosch jigsaw and was very glad I did once I found out how many parts were inside! Good luck and hope I was helpful.

The gun won't put out any nails anymore......It is a cordless bradnailer..

If it is the cordless Brad Nailer and will not fire nails anymore chances are the drive belt came off track. Internally those DeWalt cordless nailers operate much like a Baseball pitching machine. And when you fire a nail the drive belt pinches the driver blade which fires the nail. Here is the product documentation from DeWalt's website.
The Drive belt is part #59. I have never opened one of these before so I can not tell you if it is a simple fix, I would open it up and peek around just a few screws on the top should open it. If you do not feel comfortable opening that unit yourself, I would take it to an Authorized DeWalt repair facility.

I have dewalt dc618, nail doesn't goes all the way in, please help?

Below find information on how to adjust for depth, however if you have already made adjustment then check for broken tip on driver blade. The blade is not expensive and available from dewalt service center.

Please note the following from manual:

Adjusting Depth
The depth that the fastener is driven can be adjusted using
the depth adjustment wheel (C) on the side of the tool.
WARNING: To reduce risk of serious injury from
accidental actuation when attempting to adjust depth,
• Remove battery pack.
• Engage contact trip lock-off.
• Avoid contact with trigger during adjustments.
1. To drive the nail shallower, rotate the depth adjustment
wheel (C). There are twelve depth settings, 1 being the
shallowest and 6 being the deepest.
2. To sink a nail deeper, rotate the depth adjustment
wheel (C) to a higher setting.

Brad Nailer not firing. Just a shot of air. adjusting no help

Maybe is time for a service maintenace, this units you can replace all the O" rings, they came in a MaintenaceKit (with instructions) and price is real low., comparing to other brands. Keep in mind, the oil "eat" the clear plastic rings that are inside, that is why u can NOT put a lot of oil , just 2-3 drops Pneumatic oil per day. Also water\humidity from the compressor damage all components inside the nailer. Do not be afraid to open it (just to take a look inside) is 4 screws. of course is the unit is still covered by the warranty take it to your nearest servicenter.

hope this will help.

Gun wont sink nail

sounds like safety needs adjusted you have bent the arm and it is thinking that the guard is not fully depressed and thus it vents air . adjust it with wrench or straighten arm. I have had this happen before- but in my case the adjuster backed off- same result -look in manual for adjusting as well - should be there or take to service -easy fix and should be cheap
