Hello I was cutting a little bit today and my new sawblade and new saw had a problem .. What happened was ..well all day it was smoking .. i added some more oil and that helped a tiny and i added a lil more no smoke and that helped a lil .. luckily i was sitting right next to the saw when it started to slow down to a stop !!!!.. i tried a couple more times and then decided to tighten the belt to make sure that was tight enough cus it was a lil loose ... after about 1.5 hours of taking all the bolts apart and retightening ... it was working okay ..but was much cooler and dark now so i couldnt cut anymore than the first cut .. ... when it was hot i also tried using that stick to sharpen the blade John gave me along with my belts ... that didnt work either ..???help !!.

Two questions. #1 -- Are you using a thin blade ?
#2 -- Does your saw have a power feed ?
I think you can see where I'm going with this.

That dressing stick is likely too mild to do much for your blade. Is this a Blazer blade? If so try hand feeding a few rocks. Sometimes painted blades have so much paint it takes a while to get down to the diamonds. If you can get an old SC wheel or a fire brick or fake concrete type brick that would work as a dressing stick. The sticks for diamond belts are 200 grit. Also since it is a new blade make sure you didn't over tighten it. Just enough to prevent slipping. Too tight will dish the blade and make it wobble.

I had a truck like that once Try a fireplace store, particularly a place that sells wood stoves. They often sell such things as replacements for existing stoves.

You said new saw so i figured new oil . I bet the dirty oil is the problem . i had been adding to mine for to long . Causing my motor and blade to get hot , would`nt cut bigger rocks that it normaly would . put new oil in and cuts like a champ now .

Try an oil change first. Hopefully you're using mineral oil, not a thicker oil like hydraulic oil.

Those will do the trick. But you don't really need 6 of them. 1 Brick should last a couple years.

I got a fire brick from Home Depot (around $1.50). I had to ask one of the workers and they found a pallet of them hidden away. Apparently it wasn't a fast seller.

The fire brick I got is yellowish and about 8 or 9lbs. I couldn't find it on Home Depot's website but at my local store, they had a pallet of them. It was in their catalog so I would bet they could order some in. I think it was a "medium" duty firebrick with a certain temperature range (not that it matters for saw blade dressing). I've only used a small chunk of it when I was constantly dressing a really old worn out blade.

Just make as thin a slice as you can. Unless you're really hard on blades, 1 or 2 bricks should last you a long time. I have 3 or 4 of them in my shed, left overs from building a brazing table for a place I worked at.

I'm pretty new to saws here, just got my 12 inch recently. Could someone explain how cutting a firebrick can help sharpen up the blade?

Jon, welcome to the forum. Since diamond saws get pretty hot the steel will eventually begin to roll over the diamond which created more friction and accelerates the process. Cutting fire brick or a blade dressing stick grinds away the steel to expose new diamond. Cutting obsidian also does a good job of keeping the diamond exposed as ling as you do it before the blade gets extremely dull.

Jon, over time and use, old diamond on the surface of the blade wears down, This allows the metal bonding the diamonds to wipe over the diamonds. The cutting will slow down, or even quit. By cutting through a fire brick, blade dressing stick or even a piece of obsidian you will remove enough metal to expose a fresh layer of diamonds. The blade will start cutting again. This will happen several times over the life of the blade.
