I bought these tools (Air Compressor & Impact Wrench) to change winter tires of our vehicles, but when i was reading the manuals there is a warning that these tools should not be used in cold weather.
I do not understand then what is point to use these tools, I just want to further understand, does someone uses these kind of tools in winter? it looks me like warning is subject to some circumstances
Thanks

Welcome to the forums.
Compressed air carries moisture in it that can freeze in the air hose or inside the turbine of your air tool. Keep the equipment inside where it's warm until you need it. Use it and then bring it back in. Keeping your impact tools oiled is helpful in the cold.

I've never had any issues using either of my compressors in cold weather although my portable compressor has had the pop off valve stick open a time or two until it warmed up. You should always bleed the tank to remove moisture when you get done with the air compressor which will also prevent any ice from forming in the tank.

In the 40+ years that I have had air tools and compressors in my unheated garages I have never had an issue with moisture/water in cold weather and I use some of these tools year round.
Moisture is not an issue in cold weather and as long as you drain the tank and moisture traps on a regular basis there shouldn't be any water present!

I believe one important thing i forgot to mention that we have extremely low temperature in winter, it could be as low as -15 inside the garage.
One other reason that comes to my mind if i fill the tank in cold and after use i do not empty it and leave it as is, when temperature raises it could be dangerous as well.

Your tank has a pop off valve that should open any time the tank's pressure gets above a certain point. On smaller compressors that is often 125 psi.
I don't have any experience using an air compressor below zero. I wonder if a different oil would be called for ??

You absolutely need to be sure your oil is compatible with the low temps, that is a completely different issue!
