How much pressure? Foam pad or microfiber?

Not too much pressure* & foam pads. I was using the Griot’s foam pads that come with the 5” backing plate conversion kit.
* I’m strength compromised and there was no hint of pad stalling at all.
When asked about speed, is it not capable of running at higher speeds without heating up the tool?

Any mechanical machine that has moving parts will get warm, some even hot, during use. And the higher the speed, the higher the temperature... It's basic physics.
For your polisher, if you can hold it comfortably in your hands, without burning your hands, then what you are feeling is probably normal.

It sounds like it’s normal, foam pad, speed 5, no excessive downforce, it’s probably just the normal heat the machine will produce. Shouldn’t burn your hand but will feel warm for sure.

Where are you feeling the heat? What was the weather like, or how warm was your garage?
I used my G15 a couple weeks ago to polish out my car and never felt any heat at all, granted it was only in the 60's~low 70's at the time, but I didn't feel anything. My old HF DA would get hot after extended use and in the summer when the garage was in the 80's it would really heat up.

Were you using an extension cord?

Used it again today. Had to use an extension cord but I used one of the most heavy duty ones I had. It’s where the brushes are that got hot. Never went above 5 and tried to keep it at 4. When my helper picked it up, she oMost dropped it saying, ‘it sure gets hot.’

That would be the expected spot that would get hot.

I also noticed the G9 getting very warm when I first used it. I discovered that I was blocking the air intake with one hand and blocking exhaust vent with my other hand. I changed my grip and made sure that the vents were clear and it ran a lot cooler. The intake vent is located just below the speed selector dial. The exhaust is located near the pad. All fan cooled electric motors need to breathe and they have an internal fan to move air across the stator. If that air flow is blocked, it can cause overheating.

Took some temperature readings after using my G9 to do some polishing yesterday. Temperature outside was 80-85. These were just after turning it off. Wasn't going try taking temperatures and pictures with the machine running but the spot that was 108 saw up to 130 while running for a few minutes.
