Detergent ß ow adjustment
(For machines with Chemical Mixing System)
1. Turn the knob (A, Fig. 4) clockwise or counter-clockwise to increase or decrease the detergent concentration.
2. The average detergent concentration values, matching the 4 coloured areas of the scale (B), are shown in the Þ gure.
3. To set the detergent quantity to zero, fully turn the knob (A) counter-clockwise.
NOTE
The detergent concentration is kept constant even if the washing water fl ow is changed with the switches (C) or (D).
Working with brush/pad-holder extra pressure function turned on
If the ß oor proves to be particularly difÞ cult to clean, it is possible to turn on the brush/pad-holder extra pressure function by
pressing the pedal (11) to position (11c).
CAUTION!
In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from turning, or to
excessively aggressive fl oors/brushes, the safety system stops the brush/pad-holder after about one minute of
continuous overload.
The overload is shown by the three warning lights (81a, 81b, 81c) fl ashing 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/pad-holder stops.
To start scrubbing again after a brush/pad-holder 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/pad-holder is automatically tuned
off, while the vacuum system and (only for SCRUBTEC 545BL, 553BL and BOOST 5) the drive system stay on, to Þ nish drying the
ß oor 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.
