Abstract
A saw () being portable and/or wheeled, such as a wall saw, floor saw or masonry saw, comprising a rotatable circular saw blade (), a drive motor () with an motor output shaft () for rotating the saw blade (), and a transmission () for interconnecting the motor output shaft () to the rotatable saw blade () in order to change an unsuitable high speed and low torque combination of the motor output shaft () into a more useable lower speed and higher torque combination at the rotatable tool (), wherein the transmission () comprises two adjustable friction saw protective clutches in parallel, which can be set at a desired predetermined value, so as to limit the maximum size of the forces that the teeth and gears of the transmission () are exposed to. No over dimensioning is necessary, and the transmission () will make out fine in rough environments. The transmission may be of single-speed or two-speed type.
