As far as I know, there are no legal owners' manuals or workshop manuals online for Kioti tractors (at least none available to owners). A couple of dealers (like Michigan Iron Equipment) have online parts manuals which are superior to the paper parts manuals because they are easier to use and get some updates. I have found numerous errors in the paper manuals for my 2006 DK45S and those manuals are cryptic. More recent manuals (like for SE series) look better,at least more complete. I suspect dealers have access to better online data, but that's a guess on my part. At one time a foreign web site had many manuals that could be downloaded but that site is now restricted/password protected (or may even be gone AFAIK). Somebody sells digital manuals on CD via Ebay, which must be illegal from a copyright standpoint. There is a thread on this site which, in effect, is a petition for owners who want digital manuals to be available from Kioti (I am not hopeful this will happen). Personally, I urge every owner to buy a paper workshop manual for their machine. Owners should have already received a paper owners' manual with their tractor. IMHO, it's irresponsible for an owner not to have an owners' manual.
