Charging an Agrotk 680 with nitrogen

[@rongray4118]

I am looking at one of the units right now! I was wondering what the nitrogen was about - thank you so much for explaining it!

[@MooneysExcavating]

No problem! Glad it helped.

[@linctexpilot8337]

Thanks for this video!!

When the point dulls you will find it works better. Better to shatter the concrete then drill a hole in it. Fractures out the bottom better. Also i have been told it’s not good to dry fire a hammer. Just a few things i have learned along the way. They are very useful tools.

[@robertsinclair6779]

Big Question: Where did you get your nitrogen tank charged? I can't find any place that charges Chinese tanks.

[@ericmartin9299]

I'm guessing the nitrogen is acting like the return spring to cause the hammer itself to oscillate "pound" what it is placed against. I've never operated one of these. Can you explain how these operate?

[@MooneysExcavating]

you said it yourself lol, that's about how out works

[@Northwestprepper411]

Just bought one for my mini excavator, only gave 600 for it. I was wondering how to put the gas in it, thanks for showing me.

[@markbenavidez6398]

Hello so when you remove the gauge after filling does any gas come out or only if you were to push the button? Great video thanks for the help.

[@MooneysExcavating]

@@markbenavidez6398 no gas should come out. The push pin it was will add or remove gas when pressed

[@juanreynoso4621]

When i went to get the notrogen tank filled they asked what type of Nitrogen?

[@rickypope9016]

I'm looking at one like you got with post driver, how has yours held up?

[@rickypope9016]

I got one getting nitrogen tank next week. Getting it ready I put a good bit of grease in it and not seeing any coming out. Does it suppose to come out bottom?

[@steveredman5074]

Do you also have to charge the high-pressure side to 853 psi?

[@MooneysExcavating]

@@steveredman5074 only have one side for this specific model.

[@jvcvideocamera]

How did you get the supplied tank filled? I can’t find anyone who will fill it because it’s not made to US standards. Too much liability. Plus, its made with oxygen threads, not nitrogen threads. I’ve been to 4 tank suppliers and no one will touch this because of these two issues. Currently I’m searching for an adapter for a U.S. nitrogen tank to the hose they provided me, with no luck.

[@WW-lm5ji]

I had the same problem. I wonder if I can substitute air

[@MooneysExcavating]

Mine came filled already. There’s a welding shop down the road that would fill it too.

[@scottacampbell2472]

I have the same problem. I'm working with Airgas to find an adaptor to a Nitrogen bottle. AgroTK support has been almost nonresponsive and no help.

[@jvcvideocamera]

Update- what I did was forget the Chinese tank that was supplied. Get yourself a US nitrogen tank, then get a thread adapter (Western Enterprises #415) for male nitrogen threads to female oxygen threads and you are good to go.

[@randallthompson3861]

Western Enterprise #415 thread adapter; OMG! Thank you!

[@johnkisst9262]

Do you leave the gauge on after you fill it during operation? Or remove and put plug back in?😊

[@MooneysExcavating]

Common since isn’t so common I guess.

[@davidcampos5844]

Where did you get the tank filled?? I took mine to a gas store and they said they would not dare to touch the tank 😂😂

[@robertsinclair6779]

Same experience here.

[@davidcampos5844]

@@robertsinclair6779 I ended up buying a local tank then I went to hydrolic fitting store to buy the conector.

[@leemiller6676]

Where do you find nitrogen

[@MooneysExcavating]

It comes with the unit.

[@ewsconstruction6421]

How has it held up

[@MooneysExcavating]

Have used it about 5 times this month, hasn't had a problem yet.

[@linctexpilot8337]

You should try it with 300 PSI in it and see how it operates

[@MooneysExcavating]

I actually had it filled up a little too much and it wouldn't operate correctly. I removed some and has worked flawlessly since then.
