SOURCE: air stapler leaks air through ''nose''

This sounds like one of the O-rings has failed. Yes it can be fixed. Check to see if HD has an O-ring kit for these guns. That kit will contain all of the O-rings as well as the lubricants for a total rebuild. That should resolve your problem.

SOURCE: air leaks around green cylinder at trigger area

Your nailer uses a trigger valve (part # tva6 cost about $20) and is sold at www.bostitch.com or generic valves sold on ebay . If you have a source for orings, you could try to repair the valve. Remove the roll pin that holds the trigger to expose the tva6 valve. There are roll pin/pins that hold the valve in just above the valve in the body. Remove these pins and apply air pressure to gun to pop-out the valve. Use caution when you do this. Remove nails, lower pressure to gun and use glove or rag to catch valve because it could come out with force. With tva6 valve in hand remove two pins that hold valve together and remove inner plunger. The middle oring on plunger is cause of leak. Try using an oring about same size as the broken seat. It must fit pretty tight to work. If you had a small leak it could be that the firing pin orings fit too loose or just too worn. Use silicone lube or oring lube on the orings and the valve port. Good holidays.

SOURCE: I have a power fist stapler nailer 8042509 which

Travel of driver blade /striker is controlled by lower bumper. Remove driver blade and cylinder to examine the bumper. It should be complete not cracking or chipped. If worn replace to solve problem. If it looks to be in good condition, add thin piece of rubber under the bumper to space driver out a bit. Use piece of inner tube or similar and make small hole to pass the driver blade. Other solution would be to actualy grind the end of the driver a bit. Good luck

SOURCE: does the campbell hausfeld model

Sb504000 works just fine with pressure range from 60 to 120 psi depending on material. Any small compressor will work great. Using the gun at max pressure will shorten the life of the gun. Best practice is to set pressure to just under 100psi for most work and increase pressure when nailing hard wood. Using at max pressure will strain the driver and the lower part of gun (screws that hold nose to body). Some hard woods will bend an 18 gauge nail. Good luck with your gun and have fun with your projects.

Pneumatic stapler trigger stuck


The click sound indicates that the headvalve opened to fire piston down the barrel, however piston is already down or is stuck in-place. If the piston/driver is not broken or stuck, push piston to top of cylinder to reset. If only one shot and piston stays down, most likely the check band is broken. Check band is on the outside of cylinder (lower part) is is usually an oring or band of rubber covering small holes drilled into cylinder. Check valve /band is what causes the piston to return to top. If check band is good, most likely piston is bent or oring is too tight. If you open the gun, lube all parts with white grease or silicone paste lube. Good luck

Paslode stapler


Several things to check for piston not returning to top of cylinder. Most common problem is bent/ broken driver. Worn oring on piston is second most common. Piston should move easily in cylinder but hold in place. Point nose of gun up then down again, if the piston moves within cylinder, replace the oring. Lower bumper and washer with slot under the bumper must be in good condition. If the bumper is cracked or missing pieces and or if the washer fits too loose around the driver blade, the piston may not return to top. Finally, pull out the cylinder and make sure that the check-oring is in place around a series of holes on the middle to lower part of the cylinder (small groove cut into cylinder with several small holes). Good luck with your repair

I just put a repair kit in my sx150 stapler and it fires put will not recoil i think im missing a spring in the bottom of the piston cylinder?


The Bostitch SX150 pneumatic brad nailer/stapler uses air to both drive the brad or staple and to return the driver/piston assembly to the top of the gun for the next firing. There is no spring that goes into the sleeve or under the piston. If your driver is not returning to the top of the gun you may have put an o-ring or seal in the wrong place or left one out. The o-rings and check seal on the bottom half of the driver sleeve are what control the air that returns the piston to the top so check those first.

DRIVER DOES NOT RETURN ALL THE WAY TO THE TOP


What air pressure are you using? Anything under 80psi may not be enough to allow the piston to fully return. 90-110psi is the most common range to operate nailers and staplers. A bent driver can also be hanging up causing it not to return. This is most common on 18 (and some 16) gauge brad/finish nailers since they usually have a pretty thin driver blade.

My Bostitch MIII floor stapler is not driving staples. I partially drove one staple with a glancing blow then drove another on top. I cleared the jam and now it will not feed staples; It fires...


Slight damage to driver will prevent it from returning to top of cylinder (assuming that nailer worked correctly before double fire). Easy to check. Remove airline. Use metal or plastic to push driver to top of cylinder (should easily move). After the driver is at top, see if first cleat moved into proper positon. If cleat is not in position, check pusher and rails for debris. If cleat is in position, activate nailer to check for proper function. If driver does not return to top of cylinder and was difficult to push up, pull out driver and check for bent /damaged driver and replace orings and lower bumper while apart if parts look worn. Good luck

Why won't the driver retract on my pneumatic stapler


Can't be more specific without model number.
Driver not returning to top of cylinder is caused by several issues. Bent driver, piston oring, and check valve. Remove head and pull out driver. The blade should be straight with no missing pieces. Driver piston should fit snugly into cylinder and not drop down cylinder under its own weight. If driver / piston look ok, pull out cylinder and look for check seal in place. It looks like rubber band or one or more orings and fit in groove/s with row of holes (make sure holes are clean). Other problems related to driver not returning is/are lower bumper is missing pieces or cracked and or air exhaust port is restricted, low air pressure.

I had the same issue with an older craftsman 351-18309 brad nailer and crown stapler. When I pulled off the top of the piston, there was a denigrated o-ring. I took an ear bud for my Bluetooth headset, cut it to size and stretched it to prevent it from holding the spring... And I'll be damned it worked! It both tools!!
