Dc618 brad gun wont fire on bump

Most nailers have a two position setting on the trigger to allow for single fire or bump fire. If set on bump fire, the gun will work better when you bump fire the gun instead of placing the gun on the work then depress trigger. Bump fire works best when safety spring has good tension. Easy test. Make sure that the safety spring is in place (with air hose removed, contact foot should spring back quickly when pushed against work). With air connected, hold trigger and quickly bounce the gun against the work. If the gun does not fire when you bump, the trigger is most likely set to single fire. With trigger set to single fire, you must place the gun against the work, then depress trigger. If the gun shoots two nails while set to single fire, most likely worn trigger or worn out trigger valve. These parts are not expensive and are easy to replace. Good luck

make sure nails are loaded into the gun straight and correctly

firstly its always better to change both of the bands even if one is broken this always keeps the drive trim.all seems well clean all the contacts ie battery and gun (do not use any cleaning products this will cause grease)just wipe clean with paper towel.

Worn trigger valve orings will cause gun to fire twice, and /or attempting to single fire nail with bump-fire trigger. Easy test, look closely at firing pin under trigger. It should fit snuggly an not move from side to side in valve. If loose, replace valve. If your nailer has bump-fire trigger, do no attempt to place gun then fire one shot because the gun will most likely double fire. Good luck.

Many modern brad and finish nails use a sequential fire trigger system. You have to push the nose of the tool down to depress the safety THEN pull the trigger. This is the opposite of how a bottom fire works where you hold the trigger and bump the nose to fire the gun.

New user will jam the gun/ nails because gun was most likely not bump fired. Placing the gun then depressing trigger will usually cause double fire in the hands of new user. New user should practice on scrap lumber bump firing at many angles till they get the idea; or give them a training period with a nailer that has a single shot trigger (they may develop bad habits with single shot however).

Most nailers work better by bump firing the gun. Less likely to double fire. This is a common problem amoung brands. If you place nailer on work then trigger, you may/will have problems as you describe. There is usually an option of triggers or builtin method of single firing the gun. With single fire trigger, you can place gun on work and fire. The will not reset for next round untill you let go of trigger and lift gun off the work. If your gun is double firing even with bump method, then replace the trigger valve.

Hello. I can help you. The nail gun you have uses 18 gauge brads. I would use only original Bostitch 18 gauge.

The one MM of difference you mention is the reason why you do not have the pressure you did have. Get rid of those 31MM brads and get the 18 gauge. Home Depot carries the Bostitch line. I would go there or to homedepot.com

Professional-grade varieties are automatic, and fire a nail directly upon pulling the trigger. A semi-automatic nail gun is more appropriate for beginners, since it requires a two step process: pull the trigger and then tap the barrel against the wood. This safety feature protects the user from accidentally firing a nail gun and injuring himself or others.
