Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I've been reading several posts that talk about breaking in procedures for Ariens Snowblowers and I'm confused.  I read the manual and all I see is that the oil needs to be changed after 2 hours of use.  Am I missing another piece of instruction material?  The machine runs great and I hate to change anything but I sure want to do what needs doing so as not to take a change of voiding the warranty.

If I'm supposed to do additional maintenance please let me know what it is.  I've got about 2 hours on it now and the oil change is on the agenda for the weekend.
