SOURCE: Gun will not drive pins flush with wood. Wood is

What is your air pressure setting. A finish nailer such as this usually requires 70 lbs to drive flush. Adjust air to this value and test fire in scrap. Keep adjusting air presure until nail drives flush.

SOURCE: senco nail gun sfn30 is only firing every second nail in

You have damaged o-rings in the gun. Remove the head cap & valve assembly, remove the ring on top of the cylinder, remove the cylinder & piston. The cylinder is in tight so work it out carefully. Check the condition of the following: a split flat ring with a rubber o-ring under it on the top of the piston and two o-rings on the outside of the cylinder. If these are damaged air will leak around the piston instead of pushing it back up. The inside of the gun should be clean with a light coat of oil on everything if you are oiling it properly before use. Dirt in the gun means the gun is being laid on the ground without the air hose attached. Dry innards means no or not enough oil is being put in the gun before use. Oil pooled in the bottom of the gun means too much oil is being used. Senco doesn't make a rebuild kit for this gun, you'll have to go to the Senco website http://www.senco.com/ or other website like http://www.ereplacementparts.com to get a parts breakdown of your gun and order the o-rings (any part beginning with LB) individually. If you replace one, replace all of them and grease them up liberally when reassembling the gun.

SOURCE: senco fram pro 602 nail gun firers but no nail just a hole from firing pin

First, check that you are using the proper nails. The FP602 needs Full Round Head nails with plastic collation. If you are using Clipped Head nails with the paper tape collation the angle of the nails not let the driver catch the next nail and drive it into your work.
If you have the correct nails, check the magazine to make sure the nails are feeding all the way up to the driver. If there is anything blocking the way or if the spring on the feeder isn't taught enough to pull the clip all the way up the driver won't be able to catch the next nail and drive it in.

Pin nailer problem


Nice video, you did not mention a model number so I will give you general information. If your nailer is oil free type (gun will have stamped on body, no oil ), and you have been using oil directly or indirectly, most likely rubber diaph. is bad or leaking slightly thru head. Replace headvalve. If your nailer uses orings in the head /headvalve instead of diaph. type firing valve, remove head pull headvalve and apply plenty of white grease or silicone paste and retest. If gun works with grease then most likely needs oring kit and or trigger valve or orings in the trigger. If the gun still will not function correctly with grease in the head, then orings in the trigger are worn. Good luck

Senco nailer won't fire nails, but the firing pin dents the wood almost 1/4 inch.


Hi Jes,

Are the nails moving freely in the magazine if you pull the mag spring back? If so, then the driver blade is not returning to top dead centre - leaving enough of the blade to stop the next nail moving into the nose. This could be caused by a slight back pressure in the cylinder so, check the exhaust is clean and free of any swarf. Or check the O Ring on the driver blade, even though you've just replaced them....

First get an exploded view of gun and parts list and numbers from senco.com,,take nail gun apart,,,take a good look at the rubber bumper stop to see if it is broken,,look at the driver nut to see if it is tight,,,,you can go to juldan.com once you have gotten a list of the worn parts,,,juldan sells complete o ring kits along with nearly all parts needed for your repair

When a firing pin won't return it's usually caused by damaged o-rings inside the gun. The most likely culprits are the o-rings around the outside of the cylinder or the rings on the drive piston. Another cause could be a cracked cylinder or bent driver. Remove the cap on top of the gun and check the condition of the o-rings, cylinder and driver. You'll have to order any parts that need to be replaced as Bostitch doesn't make a rebuild kit for this gun. Don't forget to lightly oil the o-rings with pnumatic gun oil when reassembling the gun. Most pin and finish nailers say they are oil-less but they still need a drop once in a while to keep the o-rings from being damaged.

Senco SN4 misfiring intermittently


This is a discontinued tool by Senco but there are still parts available for it. It sound to me that the o rings and possibly the firing valve need to be replaced. I would recommend going to Senco.com and you will find a complete parts diagram in their discontinued tool section. They also have a toll free number if needed and you can talk to their air pro. I have rebuilt quite a few of these and they are not that hard just make sure to clean all the parts and use lube when replacing O rings.
