My Dewalt framing gun blows compressed air thru the nailer nose? Thx Kurt
Rebuild gun with gasket repair kit.
How it works: Compressed air enters through air hose and fills gun cylinder.
When trigger is pulled, air inside cylinder rushes out and pushes firing pin that shoots nail.
Inside the gun there are gaskets that seal the nose, the trigger and the cylinder head.
When any of those three gaskets fail, then air starts leaking.
Putting a few drops of nail gun oil into gun before connecting hose is supposed to protect gaskets.
But everything wears out, and sometimes folks use 3-in-1 oil instead of gun oil.
3-in-1 is detergent type oil and will cause gaskets to fail.
Another thing is guns that are not used frequently and gaskets get dry.
Putting in a few drops of oil and then immediately shooting gun will cause gasket to fail, because gaskets are still dry.
Best to put in plenty of gun oil, and let oil go down into gun for a few hours before connecting hose and shooting. Even so, nail guns are designed to be used every few days with continual oiling.
