Hey, I'm having trouble with my Dewalt 18ga Brad Nailer trigger. Can you send me the directions you have on how to get into this thing? I'd really appreciate it.

For removal of dewalt D51238k trigger valve. Remove the nails.
Remove the pin holding the trigger in place. Then remove two roll pins in the body of the gun just above the trigger (3mm roll pins). With gloved hand, apply air pressure to the gun which will pop out the trigger valve. Use caution because the valve could come out with force. Try with low pessure first, then increase as needed. If you are removing the trigger because the gun will not fire, (only puff of air from trigger area), suspect problem in the head valve instead (usually, trigger valve is bad if air leaks from trigger when you connect air ). Good luck
