Abstract
Abstract A power saw, e.g. for cutting logs, is mounted on a skidsupported base connected at three points (partly by way of the saw motor) to a three-legged carrying frame. The legs of the frame are telescopically received in respective sockets in which they are independently adjustable with the aid of indexing pins and clamping collars.
