My hoover steamvac trigger won't spray


Remover the upper handle assembly and check the linkage (inside the upper handle) where it connects to the button/trigger assembly in the handle grip. This may have detached or the trigger may be loose from its mount in the handle. Reattach or replace the broken part.

When you pull the trigger air comes out near the trigger and no nail is fired.


The problem that you describe indicates that the orings within the trigger failed. You could replace the orings if you have a source for very small rings (2mm x 1.5 for the firing pin inside the trigger valve) or just replace the whole trigger assembly (under $10). Lube all orings with white grease or silicone paste lube (remove head and lube head valve assembly). Good luck

All the sudden the nail gun stop working, pull the trigger air leaks out at trigger area


I had a similar problem with one of my nail guns. What I found was a small rubber o-ring in the trigger mechanism had split. Once I replaced this the problem was corrected and the unit functioned fine.

You could replace the whole trigger assembly for about $35. But if you remove the assemble and replace the split-ring this would only cost a couple of bucks at most.

Trigger assembly shown below. ereplacementparts.com is one possible source for the trigger assembly others can be found on the Internet.

I have a Stanley Bostitch N80SB with the sequential trip kit. I have installed a new trigger valve assembly, and the unit now holds air pressure, but the trigger will not activate the plunger. I can...


The safety foot assembly pushes up on inner trigger lever which in turn pushes on the trigger valve. If the trigger valve firing pin is slightly shorter than the old trigger valve, or the inner lever is worn from use, the inner lever will not push the trigger pin all the way in. Examine the trigger and the roll pin that holds the trigger for wear and check that the safety is pushing up on the inner lever. If the trigger is worn replace or repair with metal type epoxy filling in worn spots and use a new roll pin.

N62FN: air leaks at trigger switch how to replace o-ring.


Be careful, the leak may be within the trigger assembly itself. Check the link below for a pointer to a parts site that also has exploded diagrams of the gun. These diagrams will assist in parts replacement. The trigger assembly should be available for around $25.

See the link below for a parts breakdown of the gun. Usually this problem is a defective trigger assembly and requires that the trigger be replaced. You can also check the Orings. If there is an air leak this can also occur.

I need help replacing a bostitch framing air nailer trigger model 28ww it's leaking air and won't work.


follow closely, do you have a new trigger assembly because the problem is with one o ring commonly referred as the purple o ring in the kits? either way the procedure to remove the trigger is first knock out the roll pin for the trigger latch and then the 2 roll pins for the trigger assembly. next get a shop rag or equivelant and place under the now exposed trigger assembly and then while holding the collar on the air chuck plug into tool and hold rag tight and trigger will "pop" out pull the chuck away and remove the 2 pins to disassemble the assembly or install in reverse order lubricating the o rings first. Let me know if you have any questions or problems.

Myn60fn is leaking from around the trigger, do I have to take the whole thing apart to replace the o rings or do I just drive out the spring clips?


You will need to remove the trigger before driving out the roll pin. After you remove the trigger and roll pin, place a rag over the trigger, remove your hand from the area, and briefly hook up your air line. (Clean your soiled pants after this part) You will hear a loud pop and the trigger assembly is going to come out quickly. If you are not prepared for this it will scare the **** out of you. Then once you have the trigger assembly out you can push the two retaining pins on the assembly out and remove the inner workings of the trigger. One note of caution. The ring you are trying to replace is a hard half moon looking ring that Bostitch doesn''t sell separately. You may see it in pieces when you take this assembly apart, or you may not. Sometimes it crumbles and comes out of the trigger exhaust. You can try to match up an oring to sit in there, but from experience it is much easier and less costly to just order the whole trigger valve. Hope this helps.

Bostitch N60 finish gun - air leaks out of the trigger when the air hose is connected


There is an oring that is probably broke in half, It is referred to as a purple o ring. You can buy the whole trigger assembly but I think that just replacing the one will get you going. Let me know and I will try and help more
