Product NR83A2. Lubricate is coming from the trigger and exhaust cover. The nailer is new and I put lubricate in the gun prior to placing the air plug on. What is the best way to drain the excess...


Excess oil will eventually be consumed /blown out of gun, however if you store the gun over-nite with air inlet pointed down, gravity will assist. I find that oil /water will accumulate inside gun especially if compressor is passing oil and/or weather conditions cause system to produce lots of water. Majority of guns that come in for repair suffer from a lack of lubrication. Several drops at start of day should be ok for oil lubricated compressors and maybe more for oil-less. If oil drips out of gun overnight (if stored as stated above) then reduce drops. What actually shortens life of gun is debris that enters gun from handling and that enters hoses during transport. Before connecting air hose to gun (with hose under pressure) momentarily connect a spare quick connect fitting and blow debris out of hose.

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.

Nail gun doesn't shoot and air blowing out vent constant.


We used nail guns for years. I still own 6 guns, but they aren't used much anymore.
You have a 'blown head gasket.'
Or there is debris from the air hose that got lodged into the gun.
There is a head gasket and a trigger gasket.
Both can blow out any time from use, lack of oil, or they can stick open from debris.
You can take apart the head and clean it up and add oil to see if that solves problem.
You can order a gun re-build kit for your model and put in the parts yourself.
You can have a nail gun repair shop do the job.

Nail guns require gun oil.
If you don't use gun for a while, oil should be put into air hose opening and then left to run down into gun. More oil is better.
If you use 3-in-1 oil or some oil besides gun oil, then it will corrode the gaskets.
When storing air hose and guns, put tape over openings so they stay clean.
Before hooking air hose to a gun, you can also put a blower on hose and blow out the line first

On the trigger of my Bostich Spiral load nail gun AND my Bostick trim nail gun air is leaking profusely from the trigger. Nail guns were not in use for about a year. When I first used them this weekend,...


A nail gun works on compressed air.
When you hook the air hose to the gun it fills a cylinder with air pressure.
When you pull the trigger. the cylinder pressure is released onto a firing pin that shoots the nail.
The air pressure line is also connected to the trigger and therefore the trigger has to be sealed.

When ever using a nail gun, you add a bit of gun oil in the back of the gun (not 3-in-1motor oil, it has to be non-detergent gun oil)

If you haven't used the gun in a while, it is best to oil up the gun and let the oil run down into the gun.
If you use anything but gun oil, the seals will give out.

Your trigger seal has given out. It is probably an 'O' ring. You can access it by taking it apart. Look for the O ring.
Bostich makes re-build kits for the different guns that you can buy on-line.
Back when I was in construction, there were several nail gun shops that sold and serviced nail guns, and sold nails to the contractors. I don't know if that business model is still active or if you have to send the guns to Bostich service center.

Do I need to oil this gun during use? I have many other guns that require oiling and have a stamp on the gun that says do, tho I do have another senco trim gun that I know is oilless. Do I need to oil the...


yes, squirt oil in the tool 2 times daily depending on use. do not oil the nails/pawl area, it only collects dirt. About 6 drops in the air fitting should be fine.

Not enough pressure through the hose


This issue usually comes from a clog in the output of the pump. Isolate the clog by checking one item at a time.

SAFETY FIRST!

With the engine OFF, disconnect the output hose from the pump. Turn the output fitting to an open and clear area and startup the engine. If pressure and volume are good then you have a clog in the hose or the gun. Reconnect the hose but unscrew the gun. Test again. If tests OK the gun or the tip is clogged. Reconnect gun and disconnect tip...etc.

Going back to the first test, if pressure and volume are NOT good at the pump outlet fitting, you have a stuck unloader valve in the pump. Add a few ounces of penetrating oil to the SUPPLY hose fitting and restart the engine. Allow the oil to flow thru the entire unit. Repeat several times if needed. For preventive measures, always add some LIGHT oil to the supply hose and startup the unit after each use. This will keep calcium buildup to a minimum.

Hope this helps,
Dolf-

Oiling


As with all air tools you need to add 2-3 drops of oil into the air fitting before you use it. If you are using the tool a lot during the day you should add a few drops several times through out the day.

How do you oil a nailer?


first off some nail guns do not need to be oiled, but the gun you have listed does need to be oiled you just drip a few drops of oil in the hole where the air hose connects to the gun, but make sure that you are useing the right oil make sure it is pneumatic oil for air nailers. the gun should have came with some oil if it was bought new if not you can get the oil at Lowes, Home Depot, or any other home improvement store

CO2 ctge expels as it is inserted into handle


Your first problem may be your seals. if the base seals have not been oiled since you bought the gun they may have weakened or cracked to the point that they no longer make an effective seal against your 12g cartridge. For now, add some gun or machine oil. If that fails you can buy seal kits from whoever made your gun, and possibly have your local gunsmith install them if he is able to. This all depends on what the gun is worth to you.
