Looks like it was not okay. The bar got hot.
I found something interesting in the saw.
When I took it apart earlier in order to clear out the oil channel, I missed something. It turns out fine dust somehow combined with bar oil and hardened like wood filler. It formed kind of a gasket that fit against the slot on the bar the oil should have been coming out of. The slot was fine until the bar was clamped to the saw, and then very little oil could get out.
Nearly every tree I cut is at least partly rotten, and the rotten bits turn into dust instead of flakes. The saw wasn't dull, but the sprocket cover had a ton of dust in it.
I had no idea wood dust could harden like that. Never seen it before. I had to scrape it off. I wonder if it's one particular kind of tree. I haven't seen this with oak before, but I have been cutting magnolias, too.
I tested it by running it while pointing the bar at the workshop trash, and oil started spraying off the end of the bar and onto the can liner. Doesn't seem to oil as much as a gas saw, but at least it's not dry.
