6. PRACTICAL GUIDE FOR THE OPERATOR
6.1. Controls - Description
With reference to fig. 6, the machine has the following controls and indicator lights:
• Battery charge light (fig. 6, ref. 1 – battery model only): 3 LEDs (red, yellow and
green) indicate the battery charge level. There may be:
a) green LED on: batteries 100% to 50% charged;
b) yellow LED on: batteries 50% to 18% charged;
c) red LED on: batteries almost flat.
d) red LED flashing: batteries completely flat; after a few seconds the brushes stop
and the brush switch light also comes on.
• Main key switch - emergency button (fig. 6, ref. 15 BT models with electric drive):
enables and disables power to all machine functions. Acts as a safety device. To start up
the machine, turn the key clockwise. To stop the machine press the button.
• Brush button with light (fig. 6, ref. 3 - all models): enables (LED on) and disables (LED
off) brush and suction motor operation.
o CT40: as well as enabling brush operation, pressing this button automatically
attaches the brushes.
o CT40 BT50 model, holding this button down for at least 5 seconds also selects
the type of machine operation, "MICROFIBRE" with microfibre disk or "BRUSH-
PAD" with brush/abrasive disk.
• Suction button with light (fig. 6, ref. 2): switches the suction motor responsible for
drying the floor being washed on ("LED on") or off ("LED off"). The light is on when there
is power to the suction motor.
• Tap lever (fig. 6, ref. 6 - 230-110-115VAC mains electricity powered models only):
provides continuous control of the flow of detergent to the brushes. Pull up to increase
the liquid outflow.
• Detergent flow regulation button (fig. 6, ref. 18 - battery powered models only):
enables the flow of detergent to the brushes to be regulated constantly. The quantity of
liquid delivered is indicated by the LEDs (fig. 6, ref. 20).
Holding this button down for at least 2 seconds enables/disables detergent flow.
On this machine, the quantity of flow delivered can be adjusted manually by pressing the
detergent flow regulation button (fig. 6, ref. 18) a number of times or automatically (BT
models with electric drive only). In this mode, the flow delivered will automatically be
in proportion to machine speed. Follow the instructions below to set the machine’s
software for the type of detergent flow:
• turn the machine on, wait 5 seconds and make sure the display comes on.
• press the brush buttons (fig. 6, ref. 3) and suction button (fig. 6, ref. 2) together for
at least 5 seconds. This accesses the battery setting menu.
• press the brush button (fig. 6, ref. 3) once to access the water regulation menu
(“MAN” or “AUT” appears on the display).
• press the suction button (fig. 6, ref. 2) a number of times to select “MAN” (manual)
or “AUT” (automatic) operating mode.
• memorise the displayed parameter by pressing the emergency or brush button.
• Drive lever (fig. 6, ref. 7): the drive lever moves the machine forwards and rotates the
brushes.
