HMST 600 S as the basic machine for an automatic system for calibrating control arm bearings. The rapid traverse speed, the working speed and the reduced retraction speed can be preselected depending on the travel. The lower end position can be queried pressure-dependent, travel-dependent or pressure-dependent and travel-dependent. The machine is equipped with an operating unit with pressure setting, pressure gauge and pressure switch. The hydraulic unit is equipped with water-air cooling.
