A common issue among nail guns is double feed or double kiss for which nail gun shoots two nails at a time. Why does my nail gun shoot two nails together? This problem especially occurs while contact firing/ bump firing.
The double feed of nails is dangerous as one nail strikes the head of another nail, which may cause injury to the users. Again, these double shoot nails can make holes on the surface along with bending the nails. To cope with this issue, first of all, you must know the reason behind it.
So in this article, we will show you the cure for some other nail gun issues, including double firing. And before talking about the solutions, we will also talk about the reasons so that you can avoid them as we know “prevention is better than the cure!”
Quick Overview
Why Does My Nail Gun Shoot Two Nails Together
Double firing/ double feed/ double kiss whatever we call, the shooting of two nails together is caused by several reasons. First of all, filling the nail chamber with an inappropriate nails magazine. For example, a 15 gauge finish nailer has a bigger nail head. So if you fill the nail chamber of a 15 gauge finish nailer with the nail magazine of an 18 gauge brad nail, then there is a high chance of double firing.
Again, in some cases, Paslode framing gun drives two nails together for the hitting of the 2nd nail before hitting the first nail by the driver. When the driver hits the second nail, it comes out by catching the first one.
Inappropriate pressure is mainly responsible for the double kiss issue. While nailing, you need to maintain adequate pressure (at least 70 PSI). And for controlling the pressure, there is a pressure dial. When the nails do not get the required pressure, the driver cannot hit properly resulting in hitting the 2nd one.
How to Cope Up With “Double Kiss” Issue
As we have already mentioned, inappropriate pressure is mainly responsible for a double feed of the nails. So what you must do is adjust the pressure while nailing. And for adjusting the nail pressure, there is a pressure dial.
And the required pressure for the nail guns for the wooden surface is 70 to 90 PSI (the pounds per square inch). If the nailer is pneumatic, then you need an air compressor that has at least 100 PSI air pressure levels.
Another thing which you have to keep in mind is using accurate nails. For example, use the magazine of brad nails in the chamber of the brad nailer, not the chamber of a finish nailer.
And the proper maintenance like oil the guns frequently, clearing the nail jams are also needed for getting flawless nailing.
The Other Common Nail Guns Issues
Nail Jam
Nail jam is a common nailer issue that all users face. Most often, a nail gets stuck inside the trigger, which causes a jam on the way of other nails. So the nails cannot come out while pressing the trigger no matter how close you are giving pressure.
The only solution is to unjam the nail jams. And it’s so easy. What you need is to remove the nail jams.
- First of all disconnect the air supply of the compressor if the nailer is pneumatic and if it is cordless then remove the battery
- After that remove the magazine to release the pusher
- Now release the pusher so that there is no pressure inside the gun
- After that, remove the front latch of the nailer and open the small front door of the gun
- Now remove the jammed nail from the center with the help of a screwdriver or a pliers
- After that, close the front door and reconnect the latch
- Finally, attach the pusher
- Now you are ready to go.
Firing only Air
Firing only air is also a major issue for nailer. It causes when the “O Ring” of the nailer is not sealed properly. To cope with this problem, what you need is just apply grease on the “O Ring” when the problem occurs.
Tips to Follow for Flawless Nailing
- First of all, use the specific nails for the specific nailer
- For example, you cannot install 16 gauge finish nails with an 18 gauge brad nailer
- Don’t install the battery before installing the nails magazine
- For corded pneumatic nail guns, check the air hose and inlet valve if there is any leak or not before nailing
- Clean out the nail gun frequently and remove the nail jam when needed
- Before storing, you need to remove the battery from the nailer and store it separately
- What you also need is to remove the nails from the magazine while storing to prevent rust
