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 653BL, SCRUBTEC 651BCL, SCRUBTEC 661BL) the drive system stay
on, to fi nish drying the fl oor and drive the machine to the appointed recharging area.
WARNING!
Do not use the machine with discharged batteries, to avoid damaging the batteries and reducing the battery life.

TANK EMPTYING

An automatic fl oat 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 fl oor is
not dried.
CAUTION!
If the vacuum system turns off accidentally (for example, when the fl oat is activated because of a sudden
machine movement), to resume the operation: turn off the vacuum system by pressing the switch (73), then
open the cover (22) and check that the fl oat 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 switch (73).
When the recovery tank (21) is full, empty it according to the following procedure.
