I think it’s done… I did check the brushes and they
look alright. Any chance it need lubrication in the
gear head or something like that?

Electrical smoke or metal heat smoke?

Dunno. It doesn’t smoke when it’s not under load… it can do some
light grinding but when I use the wheel to cut it slows
down under the load and starts to get hot.

Sounds like bearings. I don’t know what kind it is or how big, but my DeWalt seems like a good little grinder. I don’t use it all that much though.

Well, it’s a Makita… I don’t like it very much. I want to
get one or two more grinders anyway to leave them
set up.

I found a Hitachi at Costco a few years back, and picked it up for cheap, thinking it probably wouldn’t last… Well It has out lasted all the others (a dewalt, ryobi, pc) except the old milwakee. I recommend it. If it is smoking under load, I am thinking electrical and that something is done in there.

Sounds like it is on its last legs.

People will roll their eyes but I am completely sold on the harbor freight orange ginders. 14 dollars on sale. Before people get all up in arms about harbor freight tools here is why I only use them.

I used to run a boat repair business. We had two house boats come in with leaking steel pontoons. We had a LOT of grinding to do. By a lot I mean those grinders were running for hours at a time. Prep work on one boat alone was close to 12 hours of grinding old poorly done welds their last mechanics did. I hauled out my Makita that was less than a year old, bought a dewalt and one of my employees brought a HF grinder he had been using daily, to repair propellers, for about a year. The Dewalt and the Makita died before all of the prep grinding was complete. His harbor freight was older than both and ran perfect through the whole job. After my two died I order three from harbor freight because he needed his at home for his prop repairs. I only had to use two. That was 3.5 years ago. One grinder I bought then finally died a few weeks ago after it took a 6 foot fall onto concrete. So, I finished the job with the second one. I don’t repair boats any more but as I learn how to weld I am finding that I have to do a LOT of grinding. Less now than when I started but still a lot. At 14 dollars you don’t feel bad abusing the hell out the grinders and they just keep going. Make sure you tighten the screws on the head of the grinder. They were loose on all three. I keep one with a flapper and one with a wire wheel. I am going to order two more so I can have one with a cutting wheel and one with a grinding disk. As with all things from HF, YMMV.

I have one from HF I like. I bought it years
ago and they no longer carry the same style.
