    1. Information Caution: • During all work at the machine, secure it against unintentional movement. • Only carry out work at the machine when it has been de-energised (disconnect the battery plug), except for current and voltage measurements. • After repairing electrical drives, measure the starting and operating currents to detect possibly still present errors.

  • Page 8: General Information

    2. General information The Scrubmaster B175 R is equipped with a multifunction display on which all machine statuses are displayed and machine settings can be made. If a fault occurs, the wrench in the display lights up and the machine beeps. The current service code (four-digit alphanumerical code in the service indicator) is shown with flashing dots between the characters.
  • Page 9 2. General information Scrubmaster B175 R The Scrubmaster B175 R is available in working widths of between 85 cm (cylindrical brush) as well as 90 cm and 108 cm (plate brush). The machines are delivered from the factory with batteries as standard; here it is possible to choose between a maintenance-free 36V/280Ah PzV trough battery and a 36V/320Ah PzS trough battery.
  • Page 10 2. General information Configuration machines are manufactured order-specifically according to customer wishes from a pool of available equipment features.
