•
Make sure the squeegee (fig. 2, ref. 6) is firmly attached and connected to the suction hose (fig. 7, ref. 4). Make sure the back
blade is not worn.
IMPORTANT: If you are using the machine for the first time, we recommend trying it on a large obstacle-free surface first to acquire the
necessary familiarity. Always empty the dirty water drum before filling the detergent tank again.
For effective cleaning and to extend the working life of the machine, follow a few simple rules:
•
Prepare the work area by removing all possible obstacles;
•
Begin working from the furthermost point to avoid walking on the area you have just cleaned;
•
Choose the straightest possible working routes;
•
Divide large floors into parallel rectangular sections.
If necessary, finish off by passing a mop or rag rapidly over parts inaccessible to the scrubber drier.
Working
After setting up the machine, proceed as follows:
•
Connect the machine as follows:
•
Move the tap lever (fig. 6, ref. 6 - (230-110-115VAC mains powered models only) to the minimum detergent flow position. Unless
a safety solenoid valve is fitted, the detergent solution starts flowing to the brush;
•
Lower the squeegee by means of the corresponding lever (fig. 6, ref. 8);
•
Press the brush switch (fig. 6, ref. 3) select the most suitable operating mode (BRUSH-PAD mode with brush/abrasive disk or by
holding the brush switch down for at least 5 seconds, the suction motor starts up automatically;
•
Press the suction button (fig. 6, ref. 2) if you want to disable detergent suction; press the brush/drive lever (fig. 6, ref. 7);
•
Models with no traction: When the brush motor is enabled and the drive lever is pulled, the motor which turns the brush and
moves the machine starts up. A special mechanical drive device uses the friction between the brush and floor to generate a
forward movement. When the mechanical drive lever is released, the brush motor shuts down and the machine stops. If the
machine pulls to one side, restore a straight course by using the direction regulation knob (fig. 6, ref. 10). If the machine pulls to
the right, turn the knob clockwise and vice versa.
Models with traction: to move forward or backwards, see paragraph 6.3. Periodically check that the detergent is reaching the
•
brushes/rollers and refill when it runs out. When there is no longer sufficient water in the detergent tank, the level indicator
lights up (fig. 6, ref. 5). Stop and fill the tank;
•
PRESSURE OF THE BRUSH ON THE SURFACE TO BE CLEANED (550 XTT only): during work make sure the pressure of the brush
on the work surface is within the permitted operating range - 1 green LED on, minimum pressure; 2 green LEDs on, medium
pressure; 3 green LEDs on, maximum pressure (fig. 6, ref. 17). If the 3 green LEDs and the red LED (fig. 6, ref. 17) come on during
operation, brush pressure must be reduced by turning the knob (fig. 14, ref. A). Turning it clockwise increases the pressure of
the brushes on the work surface, turning it anticlockwise reduces the pressure of the brushes on the work surface. To access the
knob, lift the dirty water drum.
IMPORTANT: Empty the dirty water drum each time you fill the detergent tank. Never leave the suction motor on and detergent tap open
when parked.
•
When the dirty water drum is full, the level indicator comes on (fig. 6, ref. 4) and after a few seconds the suction motor shuts off.
You must stop working and empty the tank. To restart the suction motor, turn the suction switch (fig. 6, ref. 2) off and then on
again.
•
If the warning LED (fig. 6, ref. 1) starts flashing, it means that the batteries are almost flat. After a few seconds, the brushes shut
down to prevent excessive discharge of the batteries. Recharge.
At the end of work
•
Release the brush/drive lever (fig. 6, ref. 7) located under the handgrip. This turns the brush/drive motor off and the machine
stops;
•
Stop the brush by pressing the button (fig. 6, ref. 3);
•
Lift the lever (fig. 6, ref. 8) to raise the squeegee from the floor to prevent the continuous pressure from warping the blades;
•
Remove the brushes (or drive disks) to prevent them from warping permanently;
•
Disconnect the batteries (fig. 5, ref. 1);
•
Empty and clean the dirty water drum.
•
550 XTT model with rollers: empty the debris bin (fig. 17).
