:welcome:Greetings and welcome to the forum, erniegiro; we're glad you found us! There are a few Honda pros around here that will be glad to help you with any questions you have concerning you're lawnmower.
As far as sharpening the blades, I would say you should sharpen them now rather then wait longer. If the sharpness is worn off the cutting edge of the blade it will soon start ripping the grass off rather that cutting it and will not give a satisfying cut quality. Take a look at the PDF attatched below if you need any pointers on how to sharpen the blade. Your lawnmower blade should probably be sharpened at least once a season.
