Sounds like either the battery is bad, or since one is new its possible the contacts in the gun are not making proper contact. Are you sure your charger is working as well ? If you have a volt meter check that the battery does have a charge on it.

If you write to Guns & Ammo magazine they will answer you. they have a column monthly about gun values.

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!

Most all nail guns can be converted to single fire, however, usually parts must be changed. Some brands have two positions on the trigger, others have a button position near the trigger to accomplish same. Check with dealer or email your gun model # and I will explain your to fix. For now you can replace the spring on the safety with one slightly stiffer. Also try nailing with trigger depressed and quickly bump the gun to fire, this method usually works better than placing the gun in position then firing. Good luck with your repair.

Any time these guns become intermittent or stop firing but the fan still runs, the first the to check is the expiration date on the gas cartridges. The do expire and this will make the gun work inconsistently or not at all.

First do a check:
The battery is good and charged
The co2 tank is not empty
make sure the gun is not jammed
try moving the guide on the top front of the gun forward

Hope this works but not for sure with out further explaination of what is wrong with more detail.

Does the fan run and the light blink ont he nailer? I have one that I just bought. I put in the wrong type of nails and got one stuck. I had to take the front apart to clear it and now the damm thing wont fire. The green light blinks and the gas cartridge is basically full, even the fan does run after I release the push lever, but no fire???

I wonder if yours is the same as mine did fire for a couple nails first just fine then got jammed...

I will try to charge the battery more.... MAybe like yours it needs a strong charge for the spark...
