Air leaking near trigger

The nose tip is most likely stuck in the ready to fire position from too much force being applied when nailing. These guns are small and sensitive to forces being applied. Try bumping it to see if the nose tip is retracting and compressing with each bump. Unplug and unload the gun before trying to pull the tip of the nose to retract if it is stuck. Check for foreign objects obstructing the trigger and safety mechanism

there are detailed instructions on my profile page under tips. and unless you damage the old ones no you don't have to replace them. Let me know if you need more assistance.

Dried up or broken O-ring.

If the trigger still works to fire the single shot, then the o-ring kit should be sufficient. If the trigger area continues to leak air, then the trigger should be replaced as well. Keep the gun well lubricated as well.

The air leak can be one of a few things. FIrst make sure that you have added some pneumatic oil to the air stream. This will lubricate the o-rings and make a tight seal. If that fails to resolve it, repalce the o-rings. (kits available for around $20). Next, woul dbe the trigger assembly itself. These triggers wear over time and are easily replaced.

See the website below for parts and a good diagram of the construction of the gun. You should be able to replace the parts by following the diagrams.

Could have the sequential trip trigger on the gun, there is a single shot trigger available! I believe the single shot is Grey in color!

yes my guns i rebuild once a year at least

Sounds like you need a repair kit or take to a tool company that installs the kit.

couple of things there are o-rings inside that trigger assy. they are either pintched in or dry. next there could be internal rubber hoses inside the gun. might need replacing. lastly the hose or o-ring going to the back side of the ram is leaking or broken. here is what i would do. you sound pretty handy with your tools so i would get somewhere clean start taking the gun apart thouroghly noting where everything went and go untill you find the problem. but first i would shoot a couple of drops of oil into the air input on the gun then hook it up and fire a few off and see if it clears up, if not then start takeing it apart. I CAN NOT STRESS ENOUGH....DO THIS ON A CLEAN SERFACE WITH YOUR HAND CLEAN. i chased a leak around in a pnumatic hammer for 3 days all because it wasnt clean on the inside..

sounds like the rubber seals have dry rotted prob from not oiling it enough, but you should be able to go on the Bostitch web site and order new rubber seals for the gun
