Abstract
The invention is directed to a tensioning device for a portable handheld tool machine such as a grinding machine or cutting and grinding machine. Such machines have an arm which includes two component sections axially displaceable toward each other and between which a belt tensioning device is mounted. The displaceable component must be displaced against the force of the tensioning device toward the component fixed on the housing of the machine when mounting a new belt. This is inconvenient and leads to difficulties when mounting a new belt. A setting device is provided which acts upon the belt tensioning device. The setting device is movable between first and second positions and blocks the tensioning force in its first position and releases the tensioning force in its second position.
