Hi Gavin.
It is an easy question to answer:
The Saxonia did not come with instructions !
I dont believ I had any instructions with any of Karstens models (A Tornado plant and and lots of advanced accessories).
That said; I think it is fair that you get instructions, if you feel for that.If you have reached out to Karsten for this; give it some days. How ever; you might have to send him once more. Thats how it is.
Investing in the Saxonia; I guess you have experience with model-steamengines ?
Its pritty much the same procedures as firing up a standard oscilating Wilesco/ Jensenmodel. Fill water in boiler, ( not all up to the top). Oil moving parts/oscilating cylinder and fill the burner with quality spirit/alcohol.Adjust the hight/level of the "wool" in the burner-ports. Light up & insert.
If you get instructions from Karsten; please let us know :-)
Good luck ! :-)
