Idle Speed: What is it?

Specifically, PD engines require a starter motor speed of at least 500 RPM. If this speed is not reached, check the starter motor and the battery.
Please provide the German text you would like me to translate.

Hey everyone, I've been doing some more research. That 500 RPM thing is probably not right. The starting speed, if it's good, is around 250 RPM with a warm engine, but what about at -20 degrees Celsius? Sorry, I'm new here.
Hi Mucki,
