Replacing the driver tip on Dewalt Dry Wall Screw Gun

Hi,
I suggest you should go into that supply store and ask for help, if they are decent, they will surely try to help you, they surely have some experience with that.

Most all of my guns are senco and the head has the moving part for fire and reload,, controlling the driver piston. Multiple shots suggests a trigger problem. No water in system right.. Well Its all O rings little ones,, skinny ones,, fat ones etc. You can open it up and check, do the head first, I think.. Its fast a off and on

drywall guns wont spin until you put pressure on the tip, load a screw and put it to the wall (or whatever) add pressure and pull the trigger

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

grab the front nozzle and pull it straight off, no turning

The bits are held by a spring snap ring that sometimes takes a lot of force to release.

Spray a little bit of CRC226 into the bit/chuck interface and grab the bit with a set of visegrips and PULL !!!

The CRC226 is available in a blue spray can at Home Depot in the electrical dept and fights rust. A can is about $2.70... make sure to get the 226 as there are other CRC products there.

Operator's manual is here.

To seat the screw deeper in the workpiece, you turn the adjustment collar to the right. To seat the screw higher in the workpiece, you turn the adjustment collar to the left.

If you've been using it a while and turning the collar is difficult, you've probably got some plaster dust, dirt, etc. built up in the threads for the collar. It's probably worth breaking that chuck and collar down, giving it a good scrub with an old toothbrush and putting some dry lube on it. I'm partial to Dupont's Multi-Use Teflon spray. It doesn't attract sawdust or dirt.

In the event you need it, exploded diagram with parts list is here.

If you don't want to mess with it, a Dewalt service center can clean your drill up for you pretty reasonably. I was in one in early June, 2010 and they had some 10% off service coupons sitting on the counter.

if air is released when the trigger is pulled then stops when the trigger is released , then the trigger is doing its job. its probably a firing valve issue. four screws will take off the top cap of the gun the firing valve is inside of the cap . first check to see if the gun has enough oil( unless its an oil less gun) if its dry then grease or oil all of the orings, if this dose not work check to see if any of the orings or plastic parts need replacing. pls rate this answer...;tks

It's not the tip, but the screw gun itself. The screw gun has a clutch on it that allows you to set the screw at different depths. You must adjust the screw gun to the desired depth. The deeper you want the screw to go, the less the clutch will slip.
