00:00well welcome back and today we're going to talk about breaking concrete now in previous videos
00:17we've talked about electric breakers and smaller breakers doing walls drilling holes and breaking
00:23concrete floors in your basement now this is a step up from your electric breaker if you get into
00:30the jobs where you got some thick concrete a foot or so or a thick pad maybe rebar in it or you've
00:36got a front the notorious concrete front steps that are sometimes just a great big round ball
00:42of concrete maybe bed springs even inside them I found engine blocks to fill up the holes inside
00:51front steps but in any case once you get over about four to six inches of concrete and it's old
00:58it's very hard you've got to step up to airbreakers and I would certainly suggest this when you're
01:04doing breaking around the pool and you're taking out the the coping or the sidewalk or whatever
01:09that's around the swimming ground swimming pool that always has rebar in it and it's very hard
01:14to break up this is going to be much quicker now what you can use is a point or a chisel
01:21the airbreaker is used very similar to the electric breaker the only thing you remember in an air
01:29breaker is don't keep holding the the trigger to turn it on and lift it up at the same time and go
01:34to the next spot shut it off each time you move it we call that dry firing when you're trying to fire
01:39a hammer like this it hits very hard and some makes of air hammers it's been known to loosen the
01:47ends off and actually push down because you're you're holding it up and there's no resistance
01:51it needs resistance on these hammers they're much heavier than the electric hammer but then again
01:55they're hitting much much harder as well so this will be hooked up to the the diesel compressor what
02:03you use to be able to supply enough air it needs 80 to 90 CFM of air to run one hammer these supply
02:09about 185 CFM so you've got lots of air even if you had a small hole in the hose you've got lots
02:13air to run one hammer you can run a maximum of two hammers off of off of this compressor and usually
02:21you'll hook the or you will always hook the whole the hose up to the lubricator to keep the hammer
02:26lubricated because air is very dry the byproduct of compressed air is water so you want the the oil
02:32to keep the hammer from from going dry and usually there's a even on the hose that you see there's
02:40sometimes a little lubricator on the hose that hooks up onto the hammer as well when there isn't one
02:44on the compressor but just make sure you put it on the on the right one if you were blowing out lines
02:51like an irrigation and everything for the using this compressor don't hook up onto this because
02:56you're blowing a oil into your airline you'd be using the other connection so you're just blowing
03:03pure air when you're using this this line here and that way you can get the your water lines your
03:11sprinkler systems blowing out and the nice thing about this compressor here is that when it started
03:18on it'll just idle at about 50 60 psi and that's just enough pressure to blow water lines without
03:26blowing them apart you have to push the button in if it has it on the compressor to get the air up high
03:32enough to run the jackhammer so for some reason you're hook everything up and you go to use the
03:38hammer and it doesn't work make sure you've pushed the button to increase the air pressure in the you'll
03:44see it on the gauge inside it'll go up to about 130 or so 135 and you'll know you've got enough air
03:50pressure to use the air hammer some of the compressors that don't have the ability to run low 50 to 60 psi
04:00you'll have to use a regulator and hook it on to your airline to make sure you're not having too
04:06much air pressure to blow apart water lines if you're using that to blow the water out of your
04:10sprinkler system okay so there's a couple other thoughts a couple of things that maybe make your
04:15jobs easier and we'll see you again soon when we when hope you subscribe
