Staple gun Troubles

[FixToolz]

Hi all,
First post.

I am repairing 2 pneumatic air staplers for my boss.

Air gun 1: Bostitch 3/8 crown btfp71875. Not working for some time. I thoroughly cleaned it, and it worked fine for a couple hours. Then after a while i had to tap it on the ground for it to fire a staple.(it did that before i cleaned it, but even worse). Any solutions?

Air gun 2: Small 3/8 crown stapler gun. This only blew air when i pulled the trigger. I cleaned it and adjusted the trigger. It worked for a full day, but the next day it returned to the previous symptoms. Any solutions?

Thank you!

How much time did you spend on these?
How much do you get paid per hour, including benefits and employer paid taxes?

Reason I ask is that a new BTFP71875 is only $49 at Amazon and you screwing with them isn't a good use of your time, but that's the boss's call.

Repairing air nailers or staplers is a thing of the past. Banner Tool here in Glendale, AZ wanted more to repair my Bostitch 15 gauge finish nailer than a brand new equivalent Hitachi cost so I just tossed it. I do like the Hitachi.

I have repaired my Paslode and Bostitch nailers and staplers a few times. The o rings or plastic internals fail. Precovid, parts could be had on Amazon or other sites in expensively. Not so sure of that now but the repairs usually mean replacing brittle aged plastic parts.

Throw them away. Get new ones and oil them before each use.

Oil is both cheaper than repairs, it will also keep your tools working longer.

I am 14, and i took this upon myself for the sake of tinkering.
I am mechanically inclined, and I was looking for a project. Im doing this outside of work.
In other words... this project is just for fun.
Thanks for your help.

Congrats on taking some initiative to try to get them fixed. You didn't mention adding oil to them. Quality pneumatic oil is very important to keep them running smoothly and it only takes four or five drops. Also sitting unused for long periods of time is not real good for them.

Well in that case, good for you.
Check that any o-rings are in good condition. They shouldn't be hard or cracked.
Clean the piston and the bore.
Unfortunately, a lot of these tools are disposable, when they wear out you can't get parts or rebuild kits.

Hey fixtoolz, good for you. nice to see the younger generation trying to fix stuff rather than tossing it & buying new
often times it's just the Orings go bad and if you can find the right size, you're back in business .

I have many nail guns from when I was working full time @ repairs & renovations.
I have a no name brad nail gun (Chinese) & several years back the piston broke. searched ebay for hours and found a listing for a piston that looked to be real close . I messaged the seller for some additional dimensions, he got back to me and said he has 3 in total, if I wanted them all for the asking price of $9 ( he was asking $9 for one, he wanted rid of them) . the measurements he sent back convinced me they would work, except the driver was a bit too long. a few minutes on the bench grinder to shorten it & few minutes to out it all back together , I had a perfect working gun again. I have 2 more spares left to boot. That repaired gun has shot literally 10's of thousands of brad nails , and well over 100,000 in it's entire life
Don;t worry about some of the comments on here, we can get pretty tough here sometimes LOL.
HAng in there, keep up the great work.
