On this particular issue, I agree with trpabc, given the description; you most likely need a new pressure switch. It's unlikely that it suddenly got out of adjustment, therefore a new one is in order.

I had the same issue you had, and after reading your post, I went down to my garage to investigate... Turns out the valves in the compressor are just simple reed valves, like on a 2-cycle engine, and my inlet valve had some gunk baked on it, which didn't allow it to shut all the way, giving me only 60 PSI. I cleaned all the parts with a wire brush, then polished the surfaces with 1000 grit sandpaper, and it runs like a new one again. :o) I don't think you can actually crack those thin sheets of metal...

You can call Harbor Freight and see if they have the repair kit available. 1-800-444-3353. Sometimes they change the models and will not have parts available. It may take up to 6 weeks for you to get your parts if they are available. Be prepared to wait. The parts will not be expensive. Depending on which seal you are talking about, you may have to order an assembly. I am directly talking about the trigger seal. This part seems to crumble the most. If you require more information please post additional information about your model and the seals you are requiring.

Adjust the air pressure on the regulator to about 90 lbs. or lower. maybe higher than 90 but that should help you set the depth.

The nail sets to deep is there an adjustment or is the bumper worn out

Hi dfreerugs,

Welcome to fixya!

Where do you have the pressure set at on your compressor? The range for this nailer is 70 to 90psi. Try lowering the pressure until the nails drive to the depth you want.

If the gun is well-used and lowering the pressure doesn't do it, you might need a new pressure regulator in the gun.

You can download a user manual at at this address:

Scroll down to the "Product details" section and click on "Product manual".

Good luck.

Do I adjust the staple depth with the pressure from the regulator?

there should be a thumb screw behind the trigger. turn it clockwise for a deeper depth and counter clockwise for shallower.
Let me know if this helps

Adjusting airpresure

There is nothing on a nailer to adjust the air pressure. You have to do it at the pressure regulator. It is feasable to mount a regulator at the gun but more likely it's on the compressor. Most nail guns are rated for 90 to 120 psi. Set your regulator to hold the hose pressure between 90 and 100 psi. Using higher pressure to set the nail will ruin your nailer. Use the depth adjustment on the gun to set how far the nail is driven.

Setting staples too deep

The depth is set by the bumper and the bumper spacer. Are you sure these were put back in? the air pressure only makes a small difference on the depth...
