Either the blade is slipping on the arbor or the belt is slipping on a pulley. If the former, tighten it. If the latter, tighten it.
Paul Logan points out that "if the arbor is tight on the blade and the belt seems fairly tight, replace the belt. As they age the get slick and won't grab the pulley".
