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

Slide 8
The Scrubmaster B260R is equipped with a multifunction display (MFD) 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.
In addition, a red wrench can be displayed above the icon of the affected unit.
The corresponding service code is then determined via the "Service information"
menu, if not shown in the operating hours display.

Slide 9
Scrubmaster B260 R
The Scrubmaster B260 R is available in working widths with a 108 cm or 123 cm
rotating brush unit and a 108 cm roller brush unit.
The 123 cm rotating brush unit has 3 brush motors, and the 180 cm rotating brush unit
is available with 2 or 3 brush motors.
The batteries for the machine are a maintenance-free 36 V/420 Ah PzV tray and a
maintenance-free 36 V/480 Ah PzS tray.
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 loose with the
delivery for installation on site at the customer’s.
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.
2. General information

Slide 10
Configuration machines are manufactured order-specifically according to customer
wishes from a pool of available equipment features. Additional options (chemical
dosing, working light, warning signal, etc.) are installed in the factory.
For more details, see the relevant current price lists.
Additional equipment features (e.g. chemical dosing system, rotating beacon,
bluespot, etc) to be retrofitted in the field can be ordered via the Editions price list.
2. General information

Slide 11
Respective settings can be carried out via the machine’s configuration menu.
Currently, these settings are carried out via the machine display. There are settings
which can also be carried out by the operator without restrictions (e.g. cleaning
programmes in Chapter 3 and several settings in Chapter 2). This is always possible if
a diskette is displayed next to the value (Chapter-Configuration-Content). However, if
a lock is displayed a diagnostic connector with order number PN 03006790 is required
to adjust this value, or a 4-digit pin must be entered in the field above it. This is
described in more detail in the Configuration chapter.
2.1 Settings

Slide 12
In order for the display of the control panel to work, a micro-SD card must be inserted on the
PCB of the control panel containing a special image file. This is required to make the control
panel work. A micro-SD card with the required image file can be stored on using the Hako
diagnostics. See chapter 2.3.6.
If the micro SD card is missing, a "blue screen” (Fig. 2.1) is displayed. If a empty SD-Card or
defective SD-Card or a formatted SD-Card is inserted, a “Black screen” either with or without
a message is displayed (Fig. 2.3).
If the “Loading Screen” is displayed, the control panel is raised but the connection to the
machine controller is missing (Fig. 2.2).
The micro SD card cannot be read by the usual computer operating systems (Windows,
Linux, IOS, Android).

Slide 13
A new machine control unit is supplied without machine software ex spare parts
warehouse. Following mechanical and electrical installation of the central control unit in
a machine and switching on the key switch, the display will be in an indeterminate state,
since no data has been transferred from the machine control unit to the control panel
(Display: “Loading-Screen”; Service Code: 4.5.2.5.).
Therefore, the machine software must be “flashed” onto the central control unit after
mechanical installation and electrical connection of the central control unit. It is
recommended, to check during every inspection of the machine, if a new software is
available. If so, the new version has to be installed to the control unit.
• Service PC on which the current Hako diagnostic software is installed. (Windows 10)
• 1 free USB 2.0 port (or higher)
• CAN-FOX interface PN 03502430
• Alternatively, the CAN-USB interface PN 03501750
• Interface cable PN 03502750

2.1.2 Machine control unit

Slide 14
Machine control takes place with the following electronics:
• Central electronics (A01)
• Control and display panel (A02) (MFA)
• Drive control unit (A04) / 4-wheel drive option — 2. Drive control unit (A05)
• Machine controller Slave (A06)
• Chemical dosing (A10)
The control electronics (A01) assumes all control and monitoring tasks in the machine
except for the drive functions. The Slave controller (A06) controls the 3rd brush motor.
As well as the group messages of the drive control unit on the display of the machine,
these are displayed as detailed flash codes on the drive control using flashing LEDs
(see Chapter 9).
It is possible to toggle back and forth between the tip switches for scrubbing, suction
and the green Hakomatic button for combined cleaning, thus ensuring that the
selected function is activated. When pressing tip switch “boost”, the brush pressure is
increased and the water quantity set to max. as long as the tip switch is pressed.
Tool operation can only be switched on if the parking brake is applied and the seat
contact switch is open.
2.2 Brief description

Slide 15
Suction is switched off by the operator via the tip switch or automatically in case of the
signal “waste water tank full” to protect the suction turbine.
Switching off by the operator:
• The squeegee is raised.
• The suction motor switches off with a delay (15 seconds).
Switching off because the tank is full:
The suction motors are shut off when the waste water tank is full via float switch S04,
which is connected to the machine control unit A01:X15.4 and A01:X15.16.
A full waste water tank is indicated by this symbol in the display of the machine.
2.2.1 Switching off suction / waste water tank full
2.2 Brief description

Slide 16
The machine has a fill level indicator for the fresh water tank in the MFA which
displays the current fill level in steps of 20 %.
The fill level is measured via a differential pressure sensor. The pressure sensor is
connected to an immersion tube via a hose which is located next to the water filling
opening of the fresh water tank. The immersion tube extends to just above the bottom
of the fresh water tank. A certain pressure is present at the pressure sensor via the
immersion tube and the hoses, which is converted into an electrical signal by the
electronics of the pressure sensor. This signal is evaluated by the machine control unit
and shown on the display as a fill level signal.

pressure sensor B04
The sensor is supplied with a voltage
of 5V via A01:X14.5. The minus
connection comes from A01:X15.15,
and the analogue signal of the
pressure sensor is present at
A01:X15.3.
If there a water column in the
immersion tube, this can result in
falsification of the actual fill level on
the display. The display is calibrated
by completely draining the fresh water
tank once. The immersion tube in the
fresh water tank is completely emptied
when this takes place.

Slide 18
After switching on the machine, all components are set to “home position” provided
that the seat contact switch is actuated (closed).
The lifting elements will lift unless they have been switched off via the micro-switch for
the upper end position integrated in the lifting element (squeegee) or the upper end
position is detected by the control unit via the integrated potentiometer.
The spindle of a new lifting element must be turned 90° clockwise before it can be
installed in the machine.
2.2.3 Machine home position
2.2 Brief description

Slide 19
The seat contact switch (S05) is connected to the control electronics A1 at
A1:X15.6+18 (NC) and A1:X15.7+19 (NO).
The control electronics (A1) responds to the relief of the seat with an approx. 2 second
delay. This means: If the contact at A1:X15.6+18 is open for more than 2 seconds
during machine operation, the motors stop.
If the switch is closed again within 2 seconds, the machine continues to operate
without any interruptions.
If the seat contact switch is not actuated for > 6 seconds while the key switch is
switched on, the machine is locked in all functions (driving and cleaning). The same
applies if both contacts of the seat contact switch have the same switch status for
longer than a few seconds, i.e. both switches are detected as being open or closed by
the machine (seat switch manipulation).
The service code 3.6.6.4. is shown in the operating hours meter. If the seat contact
switch is actuated, only driving is now possible. If the key switch is switched off and
then back on without the seat contact switch being relieved or actuated again, the
driving function is also deactivated. The machine is blocked for use if the seat contact
switch is not actuated.
2.2.4 Seat contact switch (3.6.6.4.)
2.2 Brief description

Slide 20
To reactivate the machine after triggering “seat switch manipulation”, the machine
control unit must “register” the change of the switch status or the change between
‘operator is sitting on the machine’ and ‘operator has left the seat’.
To achieve this, the seat contact switch must be opened and closed several times
while the machine is on.
A seat contact switch that has been detected as “open” by the machine (no operator
on the seat) is indicated on the control panel display via the “operator” in the top line
of the multifunction display. If the seat contact switch is detected as “closed”, i.e. the
operator is on the seat, the operator symbol in the multifunction display will go off.
‘Seat contact switch closed’ means there is an operator on the seat;
Seat contact switch ‘open’ means there is no operator on the seat.
The second seat contact switch always has the respective opposite switching status.
