To the best of my knowledge, Honda has not authorized publishing of a digital copy of the Honda service manual. If that is still the case, the link you posted is for a seller offering a stolen copy for sale. Hence, according to the rules of this forum, links to such stolen copies are not allowed to be posted, and I have removed the link from your post.
Please do not attempt to repost the link.
I looked at the page you linked, and saw this evidence that they are selling scans of copyrighted material:
Quality: Very good. Please note this manual is from a scan and not from the original digital source. That means the pictures are sometimes not perfect quality but still very high quality and overall this manual is totally usable.
