Usual cause is user has failed to oil the nailer adequately.

FULL solution is to dis-assemble the unit and look for problems with the piston and driver.

If any O rings or seals are worn, replace them and lubricate the nailer.

IF YOU happen to be lucky, you might get away with using a rod and pushing the driver back from where the nails come out and then HEAVILY lubricate with say 12 drops of air tool oil and see if you can get it to cycle.

My Porter Cable fn250c finish nailer does nothing when I press the trigger.


Could be lack of lubricant or safety foot not pushing trigger valve pin all the way in. Easy to check. Remove nails and remove trigger to expose the trigger valve firing pin. Connect air and with very quick action depress the firing pin all the way in with finger. If gun fires adjust safety so it pushes on trigger pin completely. If no fire, remove head and head valve and apply plenty of white grease or silicone paste to orings and reassemble for retest. Good luck

How do I remove a jammed nail in the SHF50?


Hi Al:
Usually nailers are built so that removing jammed nails is an anticipated activity.
WORK SAFE!!!
make sure the air supply is disconnected from the nailer.
Press the safety against a piece of wood and pull the trigger. Nothing should happen but it's just one of my safety phobias.
Now you can have a really close look at the nailer mechanism.
Remove any nails that are still in the magazine.
Some nail guns have a cam or tab that will release the face of the nailing assembly.
Others have a plate secured with cap screws or little bolts. There is often an allen wrench provided with the gun just for the purpose of taking the plate off so that you can remove the jammed nails.
If all else fails, you could check with the place you rented or bought it from.
Patience, curiosity, and safety. Keeping tools working is an adventure!

My bostitch N88RH is not firing nails


May occur when headvalve or driver is stuck (will usually make a pop or click when tigger is depressed), or tigger valve has failed or safety not actually touching trigger firing pin. Easy test, remove nails, remove trigger by pushing out 3mm roll pin or bolt to expose the firing pin. Pull back nail feeder and place the nose against piece of wood ~ depress trigger with very quick motion with finger. If it fires, reinstall trigger and adjust safety foot so that the firing pin is pushed all the way in. If does not fire, replace trigger valve (usually tva6) or remove trigger valve and replace the 3 orings on the inner plunger. If you hear a pop or click when you do test above, remove head and lube the headvalve orings with white grease or silicone paste.

Gun will not shoot nails completely;no matter what wood,thickness,etc.they drive all but 1/2"


May be due to broken tip. Easy to check. Remove nails and leave door open. With door open, lightly tap the nose of the gun against coiled rubber hose or soft wood. The driver should stay at top position. If driver falls to bottom of the cylinder, replace piston oring. Now press nose of the gun against old coiled up air hose or soft wood and squeeze and hold trigger. The gun will fire and the driver should stay in the down position untill you release the trigger (if not single fire trigger, if single fire trigger remove trigger and press the trigger pin with finger). While the driver is down, make sure that the tip extends past the nose about 1/4 inch (if air leaks past the nose in this position, replace lower bumper). If the driver does not extend past the nose, replace driver. Good luck

It wont shoot nails. It releases air by the trigger but no nails come out. Please help I am in the middle of a job. Emergency.


It may already have a nail jammed in it. You may have to take off the front face that holds the firing pin. There should be one or two screws in front just above where the nails come out. If you remove these there will be a plate that comes off and then you can remove a jammed nail. Look first to see if there is a jam before doing this. Also maybe you have the wrong guage nails or maybe you don't have proper air pressure. Hope this helps.

I have a hitachi nv 65 ah that will shoot two nails at time


I hope this doesn't offend you. What I'm suggesting is that you may not be using your nail gun correctly. Some people keep the trigger pulled and bounce the gun onto the wood. This technique works okay, but placement accuracy of the nail suffers. The other technique is to place the gun on the wood and pull the trigger USING TWO HANDS! This is the technique suggested by the manufacturer. The problem with this technique is that if you apply insufficient pressure to the gun (USING ONE HAND) the safety is not engage so you don't shoot a nail. What usually happens - I just witnessed this a couple of weeks ago - is that not enough pressure is applied while pulling the trigger so you push harder and end up bumping the gun which shoots a nail - because you have the trigger pulled, but the nail shot was a surprise so it causes another bump (and is more apt to bounce because you're using just one hand). Because it is a machine and can operate faster than your reflexes - it shoots another nail. This happens before you can lift it off of the wood, or remove your finger from the trigger. That's the reason I keep the trigger pulled and bounce it. I know that after the bounce I've set a nail, and can remove my finger from the trigger. When I need to accurately set a nail I always use two hands, press hard and pull the trigger, and release quickly. Only pull the trigger when you know you're about to set a nail, and are poised above the workpiece.

How do you safely remove jammed nail gun?


Not sure exactly what Bostitch framer model you have, but if it is powered by compressed air, as long as you remove the air hose from the nail gun, there should be no risk of the nail gun firing while you remove the jammed nail. There should be a way to access the driver area from the top of the nail gun, even via a latch or a couple screws. Remove the top part of the driver area and that should give you access to the jammed nail, which you can remove. Use long nose pliers or something similar if the nails are really stuck.
