Question about Air Tools & Compressors
Could be one of several things - first, check the contact element (part that touches the wood) make sure it is not bent & moves up and down with the linkage freely.
These are also very sensitive to volt/amps - if your battery is not up to par you can also have malfunctions like this.
Last, open the front metal cover (3 screws) and inspect to see if the return bands are in place and not broken. These are located at the top on either side of the driver blade. This is the most common repair on this tool.
Let me know if this helps.

SOURCE: nail gun double fires
There is one main part that can be the cause of the problem.
The trigger. Check to see if there is anything out of the ordinary with this. There should be some moving components attached to the trigger itself. Is any part of the trigger touching the button in the body of the gun when safety is not depressed. If the lever on the trigger is pushing on the button, even a little bit, It will allow the gun to fire again and again.

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

There are 4 orings that cause this problem. Two are in the trigger valve installed on the firing pin. The firing pin can be seen just under the trigger, however if you replaced the valve, you could assume no problems with the trigger valve. I would take apart the old trigger valve and examine the orings on the pin. The pin should fit snugly in the trigger valve cap and also in the valve. If the orings look good and it does fit snugly, most likely valve is still good. The other two orings to suspect are installed on the cylinder inside the nailer and make contact with the bulkhead (white plastic piece that seals the cylinder note parts reference 55, 74, 11 on the parts list).
