I ran a 90-lb pneumatic hammer back in my construction days. If you've never used one before, don't lean on it. Let the weight of the tool do the work, for two main reasons:

- The cycle rate is tuned to the weight of the tool; it breaks material faster and causes less wear on the moving parts

- Impact shock is transmitted through your hands, wrist, elbows, and shoulders. Wear heavy gloves (cushioning) and use a loose grip; keep your arms bent and relaxed. Lean into it or tense up, and you may experience pain or damage to your joints

Also, loop the cord over your shoulder to keep it away from your feet. Hold the tool vertically at first to create a little crater about 3/4" deep to keep the chisel in place. Then angle the tool about 20 degrees opposite the direction you want to flake off the material. Generally, you angle the tool toward you and flake away from you. Keep it off your stomach because it can cause a bruise over time. Ear and eye protection are required.

The problem with threads like this are twofold.

1.) I'm gonna spend the rest of my day wondering "why does that guy need a jackhammer?".

B.) The next time I go to use Amazon, it's gonna show me a bunch of Jackhammers that "I may be interested in".

"Hmmm. As a typical homeowner what would I need a 'home use' jackhammer for? I was thinking maybe bury someone in the basement but that's not PC anymore."

You never bury a body in your own basement. Plus the noise of a jackhammer? Too suspicious.

One can, however, buy a 55 gallon drum and hydrochloric acid from Amazon. Or so I heard.

Make sure that drum is plastic, not steel.

Or so I heard.

Funny, but when I read the thread title I was pretty confident that Pinetree was going to be the author.

...imagine my disappointment.

The one we have at work takes two men and a small boy to lift it.

Suffice it to say I have driveway in need of repair (lifting due to roots) and someone in the 40's or 50's poured a 1'x1'x 180' perimeter footing to set the now rusted off fence posts in. Also about a foot under ground. I will have to remove posts, dig holes and bust up the concrete in order to be able to set new posts. About 22 posts. I figure it will take a good long while to complete the job so renting is a poor option.

You guys are just jealous because you have no jackhammer! ;o)

I've used a similar jackhammer before to bust up floor in basement and install a sump pump. I also may need to replace a sewer line under the concrete floor at some point. House was built in 1941.

"I'm gonna spend the rest of my day wondering "why does that guy need a jackhammer?"."

Some men see an FDP post and ask why, I see an FDP post and dream -- dang, I bet I can figure out a way to need one of those things, why not?

And now they are all implicated should an investigation follow.

When I remodeled, I couldn't afford to do the deck I really wanted, so we put up a "temporary" deck (its a for real deck, just not what I want), with a "temporary" concrete footing at the bottom of the stairs. Gonna replace it one day, and gonna need to remove that concrete when I do...

...purchase rationalized.

If the concrete in that perimeter footing is sound, wouldn't it be easier and cheaper to simply drill out (core drill) the existing rusted posts and install new ones? If you need to relocate posts, that's easy too.

Example here. And Hilti makes a really good core driller.

I bought this jack hammer three years ago to work on my old fence removal - breaking up the concrete post foundations, etc. It has operated well and trouble-free. I bought some extra brushes, but haven't needed to use any. It uses 40-wt. oil and that was a little tricky to find. I also bought a 50-ft. 12-ga. electrical cord and a "bucket" type of spooler for the cord - very good investments, making using the hammer convenient.

It only weighs 31 pounds or so (about 33 with a bit), but I can remember trying to use it the first time breaking concrete off the wooden posts, and then into small pieces so I could haul them in buckets to the city dump. Lift, place, chisel, lift, etc., etc. It can seem really heavy. When I first started using it, I thought, "wtf" and after five minutes, I'm sweating and straining and feeling almost exhausted and thinking, "WTF!" But, you get used to it, how to handle it. It has really been useful and is probably one of the best purchases I ever made. Have fun!

PS - I you have a bad back, get a good back brace.

"If the concrete in that perimeter footing is sound, wouldn't it be easier and cheaper to simply drill out (core drill) the existing rusted posts and install new ones? If you need to relocate posts, that's easy too."

2" steel posts coming out, 4x4 cedar posts going in. I don't think a drill would work for me. Also, there's the rental expense again. I'm old and need to take my time with it. Rental is usually not an option. Besides, I like having my own tools and a jackhammer is a manly tool for many men! And to top it all off, the tool is already shipped and on its way.
