Working with brush extra pressure function turned on
If the floor proves to be particularly difficult to clean, it is possible to turn on the brush extra pressure function by pressing the
pedal (11) to position (11c).
CAUTION!
In case of brush motor overload, due to foreign bodies which prevent them from turning, or to excessively
aggressive floors/brushes, the safety system stops the motor after about one minute of continuous overload.
The overload is shown by the three warning lights (81a, 81b, 81c) flashing simultaneously.
If the overload takes place when the extra pressure function (11c) is on, the pedal position must be changed to
(11b). If the overload persists, the brush stops.
To start scrubbing again after a brush stop due to overload, stop the machine by turning the ignition key (80) to
“0”. Turn on the machine by turning the ignition key (80) to “I”.
Battery discharge during operation
Until the green warning light (81a) stays on, the batteries allow the machine to work normally.
When the green warning light (81a) turns off, and the yellow warning light (81b) turns on, it is advisable to charge the batteries,
because the residual autonomy will last for a few minutes (depending on battery characteristics and work to be performed).
When the red warning light (81c) turns on, the autonomy is over. After a few seconds, the brush is automatically tuned off,
while the vacuum system and (only for SCRUBTEC 545BL, 553BL and BOOST 5) the drive system stay on, to finish drying the
floor and drive the machine to the appointed recharging area.
CAUTION!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.
TANK EMPTYING
An automatic float shut-off system (36) turns off the vacuum system when the recovery tank (21) is full.
The vacuum system deactivation is signalled by a sudden increase in the vacuum system motor noise frequency, and the floor is
not dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the float is activated because of a sudden
machine movement), to resume the operation: turn off the vacuum system by pressing the push-button (73),
then open the cover (22) and check that the float inside the grid (36) has gone down to the water level. Then
close the cover (22) and turn on the vacuum system by pressing the push-button (73).
When the recovery tank (21) is full, empty it according to the following procedure.
Recovery tank emptying
1. Stop the machine.
2. Lift the brush deck by pressing the pedal (11).
3. Lift the squeegee (25) with the lever (10).
4. Drive the machine to the appointed disposal area.
5. Empty the recovery water tank with the hose (16). Then, rinse the tank with clean water.
Solution tank emptying
6. Perform steps 1 to 4.
7. Empty the solution tank with the hose (17). Then, rinse the tank with clean water.
AFTER USING THE MACHINE
After working, before leaving the machine:
1. Remove the brush as shown in the relevant paragraph.
2. Empty the tanks (20 and 21) as shown in the relevant paragraphs.
3. Perform the daily maintenance procedures (see the Maintenance chapter).
4. Store the machine in a clean and dry place, with the brush and the squeegee lifted or removed.
