Question about starting watts on Generac 10000 EXL

[standbysolutions]

I just picked up a used Generac 10000 watt generator at a local auction. It runs really well, but I couldn't find any information in the manual regarding the starting watts. Do these generators peak at 10,000 for starting, or is there a higher surge rating available?

What's the owner's manual say?
