I have a 4010 that just reached the 50 hour mark. I am not that mechanically inclined and I did mine for about $12.00. The only thing specifically outlined is the changing of the oil. If you are doing all of the other daily checks I wouldn't worry. The only problem I had wad the dealer gave me the wrong filter. He gave me one for the older 4010 not 4 thousand 10. I have no idea what it was going to cost, I was scared by what the dealer would have charged me after seeing what was charged for repairs covered under warranty. Sorry I didn't answer your question
