Question about Tools & Hardware - Others

1 Answer

Finish Nailer Nailer had not been used for over a year. Upon recent use, the driver would not return to the up position thus miss firing. I took off the cylinder cap and found that there was what appeared to be hardened brittle pieces of grease? that fell out when the cap was removed. So, not knowing what exactly it was packed with, I don't know what to do to repair it. Solutions? Thanks!

    2 Inch brad nailer misfires up to 3 or 4 times before actually firing a nail. Seems to be ok air pressure (my compressor does not have a tank, so could it be not enough air flow... even at 100 psi doesn't properly fire). Is it as others have suggested that the piston doesn't return to proper home position after firing so a nail can't be indexed into the chamber??

The particles could be built up dirt and oil or parts of the O-ring seals. This gun should be rebuilt with new seals. Check with your local lumber yards, they often have vendor days where the vendors will be at the yard offering tool overhauls at little to no cost with the purchase of nails. I have 4 guns rebuilt/repaired this way for zero $$. All it cost me was an extra $10 over the cheapest price for nails. I figured that I received $200 worth of gun service for that $10.

OK, second shot at this: About 65% of the time my SFN30 Senco finish nail gun only shoots a nail every OTHER pull of the trigger. All the O-Rings are good and the driver blade is perfectly straight.


There are 4 main causes usually with this tool:
1) Check the seal in the bottom of the cylinder (under the bumper) #BF0070 (#12 on the breakdown) If this seal is missing or worn the piston will not always return fully.
2) The pusher spring #GD0253 in the magazine is not moving the nails forward
2) The driver is bent or the tip is worn / chipped
3) The check valve ring #LB0077 on the cylinder is not sealing properly
Let me know if this helps Senco SFN30 15 Ga Finish Nailer Parts

Paslode F16 finish nailer will not return to start position after firing. Need to pull it back.


You may have to disassemble it BUT it may be that the mechanism and sliding parts are dry and stuck with glue from nails etc so may also work to apply a rust solvent to the sliding parts and let it sit and work the nailer a bit etc.

Porter cable 15ga finish gun pin doesnt retract after firing


Porter cable uses a rubber band around the cylinder as check seal to push cylinder up. Pull cylinder and make sure that the band is place around series of holes in cylinder (about center of the cylinder ). If the band is in place then check for too much air leaking out of the nose due to worn/cracked bumper or lower bushing (washer with slot). If bumper and lower washer good, suspect debris in head vent preventing air form excaping or the shaft if the driver is bent (easy to check, driver should be easy to push back up from down position). Good luck

My bostitch n88rh framing nailer will fire when pointed down but wont fire pointed horizontal.


Nailers are made to use in any position so must be something simple to fix. Most likely safety contact foot, to test, remove the nails, remove the trigger to expose the firing button on the trigger valve. Connect air and dry fire onto wood or old coiled rubber hose in various positions. If the gun tests ok then carefully examine safety foot mech. and trigger for loose components missing guide or roll pin. The contact foot must push firmly up on the lever within the trigger thus pushing on the firing button. If the safety foot and trigger are in good conditon and working ok, then problem is within the headvalve and piston orings. To test piston oring, remove airline and nails, point nailer up then down again. The piston should stay in the top position. If the piston moves up /down with movement of gun, replace piston oring. If piston oring ok, remove the head and pull out the headvalve. Apply plenty of silicone paste or white grease to orings on headvalve and reinstall and test. If tests ok, then problem is worn orings in the head /headvalve. You can keep lubing or replace orings. Examine the surface within the head where headvalve orings make contact. If there are many fine scratches, even new orings will not work very well. Try to remove scratches with very fine sandpaper. Good luck

Only shoots out one nail for every 4 or 5 trigger pulls


The gun will miss fire if the driver does not return to top position allowing nails to move into position. Could be bent driver, faulty trigger, cracked lower bumper or check valve not in place. Easy to check if trigger. Remove air supply, and remove the pin holding the trigger. Fire the nailer by depressing the firing pin with your finger. If the gun works ok, single fire trigger is faulty or safety foot is out of adjustment. If still miss fire, remove head and pull out cylinder and piston. Check for bent driver, cracked lower bumper or black band (check valve) is out of place on outer part of cylinder covering a row of holes.

If you diodn't replace the driver look at it. there might be a burr on it or also one where it slides in and out. Sometimes if it jams a nail or a piece came off of one it will lodge there and cause problems. This has happened to me in the past.

Remove nails and use thin tool to push driver all the way up to top of cylinder. If the gun fires one nail then skips, the driver is not returning to top of cylinder. If no nails fire, then nails are not feeding into proper position. Driver must return to top to allow nails to feed into position. Most common problems are bent driver, worn piston oring and bad batch of nails(head too large). Good luck

Argh...

Had the same problem, but only after about 4-5 nails. Once it jammed 4 times in a row - very frustrating.

I read the manual, took the unit apart, checked the driver - it was straight. I took a file and filed the back end of the driver down a bit so it would miss the second nail and so far it seems to be working famously.

Great unit...

Firing Pin doesn't return


The piston is returned to its firing position by air from the trigger valve after the piston has fired. It relys on the piston sealing against the bumper at the bottom of its stroke, if the bumper was damaged when the driver shattered or it was put in upside down the piston will not return. Also the piston uses air fed into the return chamber from the little holes in the cylinder, if the seal over these holes is damaged the piston may not return. Basically change the bumper and the check seal on the cylinder.

Feeding nails


Your nailer shares design features with Milwaukee and Ridgid. All three brands experience the same issue. Lets go thru a series of simple tests to determine the problem. First and most simple test, manually load the nails and fire the gun untill miss-fire. Upon mis-fire disconnect air, open latch and check if the driver is all the way up into the cylinder or is partially down blocking next nail. If driver is down blocking next nail, replace the driver oring and retest. If driver is up all the way, remove nails, reconnect airline, leave latch open and fire gun against rubber (old tire or coiled up waterhose/airhose) this time holding the gun down and keeping the trigger depressed. In this position, the driver will remain down and feeder will remain retracted. With feeder retracted and screwdriver in hand carefully check the spring tension on the feeder (should be rather firm tension on spring and the feeder must retract with good force). If no tension or weak, replace feed spring. When you finally release the trigger, the driver will retract and the feeder should return with good force. If feeder does not return with force, replace orings and spring behind feed piston. If all tests are ok, remove head, check lower bumper in gun for cracks or missing pieces. Replace as necessary. Lube all orings with silicone lube available at Lowes in the plumbing department. (Danco brand) Good luck on your repair and email your questions.
