00:00Hi there it's Larry and today we're going to have a look at a scarifier. These machines are

00:16what's used outdoors normally to grind down sidewalks, high spots on concrete pads, say

00:22the doors can't get open in a commercial operation and you got to grind down the the pad from over

00:29the winter the concrete shifted or lifted and so as you can open the door again very common around

00:35a schoolyard and school buildings where the concrete pads have lifted at the doors and this

00:42is a different motion than using for grinders this is what's called a scarifier it uses teeth

00:48it's much more aggressive if you want to take off quarter half inch of concrete this is the

00:54kind of equipment you would use as opposed to a grinder it'll be much quicker although the

01:00surface that's left on the scarifier is like taking your fingers and dragging them very lightly

01:05through the sand it leaves a little cut edge which you could use a grinder afterwards and smooth it

01:10all out and make it smooth once you got the bulk of the concrete off and sometimes that surface is

01:16not a problem it's similar to a broom finish on a concrete driveway after they poured the concrete

01:22so what you want to do is give you an idea what the teeth look like on a scarifier much different

01:31than a grinder you can see they're loose teeth these spin around and they actually flick at the concrete

01:38and chip it off also you have the wheels that it rides on and you want to make sure they're clean so

01:44that you're going to have a clean grind as you're doing it scarifying it now machines fairly heavy so

01:55it holds itself firmly onto the surface and the way to use this machine is you make sure that the wheels

02:03in the middle are there solid you make sure you're pushing down on the handle and the back wheels are solid

02:08this is not a machine that you tip up and try to grind with or put up and drag you hold the

02:15machine down solid it has a lead a spin lever here that as you turn this you're dirt you're putting

02:24the you'll see the surf front of the machine going down where the cutters are and that's how you take off

02:31more or less of the concrete you keep one hand here on the handle pushing down on these back wheels to

02:38keep it solid and your other hand will be here moving this wheel up and down as you're pushing it

02:44and grinding all concrete is not perfectly flat it has some dips and valleys so this is why the lever

02:52is here to give you that control to go along the concrete and back off or grind to get the surface smooth

03:00again they're back down to the where you want it and that way you can take more or less off as well

03:05so don't take this machine and try to hold it there and try put it up and drag it because you're

03:13getting tired and you want to have be more aggressive you can either break the cutters off or break a shaft

03:19and if the wheel isn't turning and flicking and breaking the concrete off it's not doing its job use the

03:27machine for what it's intended and how it's intended to be used it'll be more effective so that's one

03:32don't do keep the wheels down always on the surface on the back and the other hand dialing of course if

03:39you're on the other hand you'll be dialing and turning with your left hand there is a good exhaust

03:44port on the back of these as well that you can hook something up but normally this machine with its gas

03:49engine would be used outdoors and not something you'd use in your basement or try to use it in an

03:57indoor of a factory or somewhere there are special mufflers you can put on them to suppress the exhaust

04:03but it is more of an outdoor thing like you've seen around sidewalks and everything talk to you soon
