I'm Bob and today I'm going to show you how to change a chop saw blade,

Let's get started.
Alright so I have a chop saw here.
This is a metal chop saw by Evolution.
Most important thing when you change a blade is to remove the power.
Never have this, the unit, plugged in while you're changing a blade.
It's just not safe.
You never know. Your hands are on the blade something could happen.
So I have a new blade here that we opened up already because it's sealed
and what I'm going to do is, each machine typically has a lock down to keep it in the closed position
and I'm gonna release the blade to go up.
This particular saw has its own Allen key attached to it.
Most machines today always have them.
This makes it simpler to change this blade. Also the key fits the door here;
We just flip that up and right on the inside here, I'll spin this around to show you,
there's a little button you push down and that button, you can't see it there, it's right there okay.
That button you push to lock the blade and you can see it's locked.
I'm gonna take my finger off of it and now you see I can turn it.
I push the button down and that locks it.
Put the tool in counterclockwise, take it out, there's a washer, there's your screw.
Pull that retaining washer off, let it slide up and then what you're going to have to do is pull
the guard up and then slide the blade out.
Pull that right out.
I'll get my new blade and make sure you're putting the correct size in when you're doing this.
This is a 14 inch blade.
Also, you'll see on the blade here, it tells you the blade rotation.
That's the rotation or the direction that the teeth should flow in and on each machine, so this is clockwise.
So, I'm sorry counter-clockwise and this machine runs counter clockwise.
So the blade, the arrows should be going in that direction to install the blade properly.
If you put it in backwards then you're gonna have a situation where the blade will not cut your material
Let the guard down, push it in there.
Some blades come with a spacer. This blade fits the armature just fine,
but you can get some blades that will have a different armature hole
that'll be larger and you have to use the spacer.
In this situation, we don't have to.
Put the blade retainer washer back on. Put the screw back into this locking washer and hand tighten.
Push that button again.
Snug it up give it a tug. Tighten it, that's it.
Give it a spin with your hand.
Make sure it flows fine, close the shield.
Put your tool back so you can find it next time and that's it.
Thanks for watching!
