pneumatic nail guns

Like any other tools, pneumatic nail guns need maintenance in order to improve their life. There are various early warning signs that your nail gun is depreciating and if care is not taken it will become scrap metal. Some of the signs include: trigger jamming, firing only air, air leaking, and double or triple firing.

It is important to note that most pneumatic nail guns require regularly oiling in order to function properly. This is a machine and therefore it requires some drops of oil after or before. However, if not done well it can result to excessive oil leaking onto the work surface, your hands or work piece. This can leave stains on the work piece and grubby oil fingers.

Oiling of the pneumatic nail guns depends on the frequency of its use. if you do not use it regularly, it is advisable to apply it on each strip. This means once after a few sessions of use. In this case you will need to apply the oil after the nail strip has run out and before you insert the next one. In addition this will depend on the number of nails used per strip. Therefore this will vary from one machine to another.

Carpenters use pneumatic nail guns for many hours every day. Since they use the gun frequently, it requires regular oiling even daily. For most carpenters, they oil the guns at least twice daily. This is because the guns are subjected to more intensive and longer cycles. They therefore demand more lubrication. Generally the guns should be oiled according to the proportion of use.

Another reason why the nail guns require oiling is because they contain moving parts. For a machine with moving parts oiling is necessary to ensure maximum lifespan. When lubrication is done correctly, it significantly delays the eventual wear of the moving parts. Without oiling the parts will wear out prematurely and stop working properly. For instance, pneumatic finishing nail guns have a working piston, which under force of the compressed air is able to hammer the top nail. This separates the piston from the remainder of the strip. Without adequate lubrication the piston will be stuck and will not be able to return back into it’s original position.

It is important to note that lack of lubrication will cause excessive friction between the cylinder wall and the O-ring. This will cause incomplete piston retraction. This explains why some pneumatic nail guns have a problem with firing shorter nails.
