Senco SN4 nailer not feeding

My Senco SN4 nailer is failing to pick up a nail to drive. The magazine is full and the piston drives down when the trigger is pulled. The piston is driving, but not fulling retracting. I didn't see a return spring in the nailer schematic.

Ther isn't a spring, it works on air to pull the driver back up. Have you tried oiling the tool as recommended (about 6 drops a day) If not then you have a problem with either o rings that are dried out or worn so they cannot keep the suction required for the tool to operate properly. Might also be a bent driver (doubtful). Go to Senco.com and type in your model number and they list rebuild kits for this tool. If you need more assistance let me know and if I have helped with your request would you please rate this accordingly.

Why does my Senco SN 901 XP frame nailers driver stay forward?


not sure what powers the senco if it works on combustion or air could be damage O rings. Another possibility is a trapped nail under the blade. Have seen where a nail has not been driven out of the magazine but has bent and points down the magazine close to end of gun. What happens is the blade drives over the nail but becomes trapped between nail and roof of the nose assy. Probably need to strip the gun a little.

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.

SENCO ROOFING NAILER DOESNOT ADVANCE NAILS CONTINOUSLY


you have one of a couple problems. First the piston is not moving freely to advance the nails, the magazine might not be set for the nails being used, or the collation is not correct, or the feed pawl spring is broken, and the driver might not be retracting fully to allow the next nail to feed. What I would do is remove all the nails, and get a block of wood and open the door that holds the nails in place and look for free movement on the feed pistion and how the driver is functioning. If all appears OK unplug the air and check the spring on the feed pawl, also check to make sure not gummed up from asphalt, If the feed piston is not snapping it could be an oring or debris in the air hole feeding into it. Let me know if you need more assistance.

I have seen many nails that supposedly fit the senco sn4 nail gun. Some are 31 degree, some are 33 degree. All have paper collating. What angle nails should I search for to fit the senco sn4?


Senco uses 33 degree paper tape clip head, however many generic brands will label their box 30-34 degree to fit several nailers. This practice causes jams in some guns and others work fine. The goal is to save money but could cost more in the long run if gun is damaged. You can use generic (other than 33) if you take a strip of nails and place them against the outside of the rails aligned with either the line of driver path of angle of the rails. This will give you a visual as to the alignment. Best result is when the complete nail is in line with the path of driver. Next best result is when the head is in the path of driver and point of nail is slightly away from path, worst is when point hits path and head is back. Good luck

I have a Senco pro 35 18 gauge finish nailer been working fine now I just get air when I pull the trigger


could be a jammed nail in the nose/magazine area or a driver problem. is the driver fully retracted or stuck partially down in the nose. UNPLUG the air before checking. If the driver is partially down I would think a jam and fully retracted you might have an issue with the piston/driver assembly.

Problem accessing nails


Hi, No you can't. They are two different feeds. The F33 uses tape feed and the N79 uses stick feed. The N79 is a basic wood frame nailer that uses 3 to 3 1/4 sticks, while the F33 uses up to 2 1/2 paper feed. The stick nails are the most common for the older nailers and on the box look for Bostitch as the brand to fit, as the N79 was sold under that brand not Stanley. This should Fixya!

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.
