2) Some sanding kits shipping with the tool have to have the pad modified to keep from unscrewing in use. The large washer supplied with the kit must be installed by drilling out the pad with a 1" hole saw to accommodate the washer. Take care to only remove the rubber pad material, not the metal backing. Overall. the HF MP tool continues to be a dandy low cost problem solver and beats everything for price. The single speed so far has been no disadvantage at all.
