摘要

The correcting device can be fitted to a power saw (1) used for cutting grooves (12) in trees (13) to be felled. The saw blade has at least one straight-line cutting edge (7, 8). A lighting device (9) sends light at a right angle to the cutting edge to create a light marker on the ground at a spacing from the tree and/or a vertically extending marking.
