Need a manual for a HS55 older snowblower

Hi,
You will need to find your model/serial number tag to get the right one since there are three possible. There is a link to show your where to look. The page with the manuals in question is here:
Honda Power Equipment: Honda Generators, Lawn Mowers, Snowblowers, Tillers (http://powerequipment.honda.com/support/owners-manuals/snowblowers/two-stage-snowblowers)
Peace,
Clarke
