Portable sander, in particular an orbital sander, having an abrasive sheet carrier () and having clamping means () for firmly clamping opposite abrasive sheet ends of an abrasive sheet () which can be supported on the abrasive sheet carrier (), wherein first clamping means () together with an abrasive sheet end clamped thereon can be moved away from the other abrasive sheet end, clamped by means of second clamping means (), for tensioning the abrasive sheet (), and the first clamping means () have spring elasticity. Provision is made for the first clamping means () to come against a rigid stop element () with prestress in an end clamping position.

A method for controlling incidences of combustion in an unloaded internal combustion engine of a vehicle. The method includes, determining a load-dynamics threshold, detecting an unloaded operating state of the internal combustion engine, detecting an incidence of the load-dynamics threshold being exceeded in the unloaded operating state, and retarding the ignition timing to form a load-dynamics aiming-off allowance that prevents combustion knock.
