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.
• During all work at the machine, always observe the general safety and accident
prevention regulations of the legislation.
1. Information

Sheet 7
The Scrubmaster B120 R is equipped with a service indicator in the display of the
operating hours meter. When switching on the key switch, four digits are shown on the
display for approx. 3 seconds that state the software version (e.g. 1.004), and possibly
further four digits that show the last displayed service message, followed by the hour
indicator.
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.
It is only a current service message if these criteria apply!
2. General information

Sheet 8
Scrubmaster B120 R
The Scrubmaster B120 R is available in working widths of between 70 cm and 90 cm.
The machines are always supplied ex factory with batteries; here, it is possible to
choose between various battery sizes (from 180 Ah to 320 Ah) as well as between
different battery technologies (EPzS/EPzB, PzV or GiV).
Furthermore, it is differentiated between edition machines and configuration machines.
Edition machines are machines that have a clearly defined scope of equipment. In this
context, only a limited scope of additional equipment features is available. Additional
options are not installed in the factory but supplied loosely with the delivery for on-site
installation at the customer’s premises.
A separate operating manual, which describes the operating and service statuses of
the charger, is available for the chargers and supplied together with the device. The
charge indicator is shown on the machine display. Service messages of the charger
are also shown on the machine display.

Configuration machines are manufactured order-specifically according to customer
wishes from a pool of available equipment features. Additional options (chemical
