Kioti Australia does a great job making all the Kioti tractor owners manuals available free online for download. I looked at your DK5810 manual, and your tractor has the same DPF/DOC emmissions as we have in the States. Upper right on your backlight dash, should be the DPF regeneration lights. These lights stay off until a need for a regen is detected by pressure sensors in your DPF. You can turn your ignition key right one click, to light up the entire dash board, and look at all the information lights, including regen lights. Located down near your steering column is the Regen Initiation/cancellation switch.
Wow, I also see Australia gets all the new Kioti models long before the US market does. I was looking at the CK4210 model, which is a major upgrade to the CK4010 model.
