Abstract
Control method for a dust extraction module () for a chiseling tool (), including the following steps: using a fan () of the dust extraction module () to draw in an air flow Q from a certain place of a substrate () being worked by the tool (), using a material detector () to identify the material M at the place of the substrate being worked by the tool (), and adapting the suction power of the dust extraction module () as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M, whereas the air flow Q is less than the rated value Qo in the case of a material Mcontaining iron.
