Working with brush/pad-holder extra pressure function turned on (only for SCRUBTEC R 466 / R 471 / BOOST
®
R4)
If the fl oor proves to be particularly diffi cult to clean, it is possible to turn on the brush/pad-holder extra pressure function by 1.
pressing the switch (67).
To return to normal pressure, press the switch (67) again.2.
The switch (67) is enabled only when the deck (5 and 10) is lowered and the LED (64) of the switch (63) is on.
CAUTION!
In case of brush/pad-holder motor overload, due to foreign bodies which prevent them from rotating, or to
excessively aggressive fl oors/brushes, the safety system stops the brushes/pad-holders after about one minute
of continuous overload.
The overload is shown by the three battery warning lights (62) fl ashing simultaneously.
If the overload takes place when the extra pressure function is on, the system automatically reduces the
pressure on the brushes/pad-holders, thus turning the extra pressure function off. If the overload persists, the
brushes/pad-holders stop.
To start scrubbing again after a brush/pad-holder stop due to overload, stop the machine by turning the ignition
key (58) to “0”. Turn on the machine by turning the ignition key (58) to “I”.
