My senco finishpro 18 won't shoot

If your Senco coil nailer is shooting one nail followed by double nails, it could be due to several reasons:

1. Jammed Nail: The first nail may have gotten stuck or jammed in the coil, and when the driver blade pushes down, it forces two nails to come out. You can try removing the jammed nail and reloading the coil.
2. Depth Adjustment: The depth adjustment on your nailer may be set too deep, causing the driver blade to push down too far and shoot two nails instead of one. Try adjusting the depth control to a shallower setting.
3. Worn Parts: The driver blade or nose piece may be worn out, causing it to push down unevenly and shoot double nails. In this case, you may need to replace these parts.
4. Air Pressure: The air pressure on your compressor may be too high, causing the nailer to shoot double nails. Check the air pressure gauge and adjust it accordingly.

If you are unsure about how to troubleshoot or fix the issue, it's always best to consult the user manual or contact the manufacturer for assistance.

Check for correct air pressure, released safety interlock, no jammed nails, correctly lubricate the drive mechanism.

IF you have tried adjusting out the problem without joy, remove head and push piston down into cylinder till it hits lower bumper. If the driver extends past nose about 1/4 inch then you should be able to adjust to desired position. If the end is broken off then tip may not extend past nose or just slightly. Replace driver as needed or adjust safety/repair foot (look for bent safety). Good luck

I have a SENCO FinishPro18 that I inherited from my son when he died a year ago. It has worked fine till now. It does not shoot a nail when depressed against a board and I pull the trigger. I don't hear air leaking, but it seems there is little pressure. Having taken apart the head, then the base, it all seems in good shape. I have not taken apart the trigger assembly, as the removal is a total commitment. Thoughts? I could use some help.

I just had the same problem with mine. Exact same symptoms. My guess is that your gun hasn't been used in a while.

I called Senco and they recommended removing the top cap, removing all o-rings (one at a time) gently stretch them, put a small amount of lithium grease in the o-ring track, and replace the o-rings. This fixed my problem and I hope it fixes yours!

Senco has awesome tech support for their tools. I will not buy another brand because of their support. 800-543-4506

Do you regularly use air-tool oil placed in the air connection? If it gets a good workout every day, buy an 'inline' oiler that is inserted into the air line which automatically takes care of oiling. Hope this helps!

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.

i would double check the plunger to make sure its resetting after each fire.

on a compressor by the motor or on the pressure switch there will be a overload switch which may have tripped out push this back in and try it it is a black button pocking out the motor or switch buddy get back to me if this doesnt work budd
