If gun firing but nails not being driven could be one of two basic problems:
1. Nail jammed in magazine not allowing nails to move up.
Empty magazine, does follower move to top of magazine. Push gun against work piece, does fan motor start? Yes - jam in magazine or lock out bar not operating. (this would allow nail un to fire when out of nails)
2. Piston/driver not returning fully after firing, hence driver blade on top of next nail instead of behind it. This could again be caused by a jammed nail or just a nail head. Another case of not returning is the combustion chamber not making a good seal, check O rings on framer (they are steel rings on bradders) it may just need a good clean it is surprising how dirty they can get and if not cleaned a build up of dirt could break a seal. If not been cleaned for a long time worth checking piston rings, worst case scenario dirt builds up around the rings and stick fully in requiring new piston if the rings will not come out.
Nail guns work on the principle that an explosion pushes the piston driver forcing a nail into the work piece, after the explosion a vacuum is created and it is this that 'sucks' the piston/driver back up the cylinder.
Maybe A cilinderseal exacly on top of the cilinder is insecure loose on the top instead of tight , it look likes he is blowing air out by the trigger instead to drive the piston . the most types airnalers have a valve insite the top of the top cover this may also be cleaned (solvent) and so that the parts can move free inside.
Remove the nails and take off the trigger to expose the trigger valve (usually part # tva6). Connect air and spray soapy water on the valve to determine if the air is leaking from the center of the valve or around the outer edge between the body and valve. If leaking from the center, could be defective valve or debris under oring. Pop out the valve and examine internal parts for cut oring or defect. If leaking from between body, you could have cut orings installing the valve. Make sure that there are no rough edges in the body of the gun. Bump fire or single fire happens with the trigger type not the valve. Bump fire trigger is usually black metal and single fire trigger is light color plastic. Good luck
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.
The link below is where you can download the owners manual. The link is on that page near the top right hand side under the area marked downloads. Page 5 will show you were the switch is located that switches the tool from sequential fire to bump fire.
May need cylinder seal # bc0438. When this seal fits loose or is cracked, air will leak past and push piston down to bottom of the cylinder. If the seal fits snuggly and looks in good order, suspect headvalve orings and cylinder spacer orings leaking. Order oring kit and seal. Use silicone paste lube on all the orings. Look carefully at the surfaces where orings make contact and remove scratches with 300 grit sandpaper(fine scratches will allow air to leak past new orings). To make the gun work with poor fitting orings. Clean inside of gun with diesel and apply plenty of silicone paste to orings (using same orings if not cut or broken). If gun works as normal, the silicone paste is temporarly sealing the orings. It may continue to work for a while untill you get new parts. Good luck with repair.
It's quite possible that the areas through which the nails move in the tool need to be cleaned and or lubricated with light oil such as WD40. Rust or dirt from nails can build up on surfaces in the unit. Check your manual for details.
Hello harderconstr, I have that nail gun myself, and when it's working good it is a great tool to have.
Here are a few suggestions.
1. Remove the battery, make sure that you don't have a nail jammed in the the firing chamber, that has happened to mine before.
2. Adjust the depth tension on the end of the gun. You should have an alen wrench to loosen the adjuster at the tip. Slide the adjuster away from the gun, ( out ) as far as it will go and then tighten it back down. Reinstall the battery and try it again. You can re-adjust the tension after you see if this helps the problem. The adjuster on my gun was worn and I needed to adjust the tension to get it firing again.
3. I also got a new battery for my gun, and what I found was I really had to slide the battery in pretty hard to get it to click in place. Also, when you hold the gun in your right hand, the thumb side of the handle should have a very small LED light, red means it's not ready to fire, green means it is ready to fire. Make sure you have a green light.
I hope this helps you my friend!
