Tank Emptying - Nilfisk BR 601 Manuel D'utilisation

Squeegee adjustment
7. If necessary, stop the machine and adjust the balancing
handwheel (16, Fig. C) of the squeegee (12).
CAUTION!
To avoid any damage to the floor surface, stop
the brush/pad-holder rotation when the
machine stops in one place, especially when
the extra pressure function is on.
Working with brush/pad-holder extra pressure
function turned on
NOTE
When the cylindrical brush deck is installed,
the extra pressure function is disabled.
8. If the floor proves to be particularly difficult to clean, it is
possible to turn on the brush/pad-holder extra pressure
function by pressing the switch (5, Fig. B).
9. To return to normal pressure, press the switch (5, Fig. B)
again.
The switch (5, Fig. B) is enabled only when the deck (4,
Fig. C) is lowered and the switch warning light (4, Fig. B)
is on.
CAUTION!
In case of brush/pad-holder motor overload,
due to foreign material which prevent the
brushes/pad-holders from rotating, or to
excessively aggressive floors/brushes, the
safety system stops the brushes/pad-holders
after about one minute of continuous overload.
The overload condition is shown by the three
warning lights (7a, 7b, 7c, Fig. B) flashing
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 (12,
Fig. B) to "0". Restart the machine by turning
the ignition key to "I".

Battery discharge during operation
10. Until the green warning light (7a, Fig. B) stays on, the
batteries allow the machine to work normally.
When the green warning light (7a) turns off and first the
yellow warning light (7b) and then the red warning light
(7c) turn on, it is necessary to charge the batteries.
– When the yellow warning light (7b) turns on, the
machine residual autonomy will last for a few
minutes (depending on battery type).
– When the red warning light (7c) turns on the machine
autonomy is over: after a few seconds the
brushes/pad-holders are automatically stopped and
the deck is automatically lifted. Only the machine
vacuum and drive systems still operate, just to dry
the wet floor and move the machine to the charging
area.
CAUTION!
Do not use the machine with discharged
batteries, to avoid damaging the batteries and
reducing the battery life.
NOTE
In case the machine drive system cannot be
used to move the machine, see
Pushing/towing the machine paragraph.

TANK EMPTYING

An automatic float shut-off system (5, Fig. I) stops the vacuum
system when the recovery water tank (15) is full.
The vacuum system deactivation is signalled by a sudden
increase in the vacuum system motor noise frequency.
When the recovery water tank (15, Fig. I) is full, empty it
according to the following procedure.
Recovery water tank emptying
1. Stop the machine by releasing the pedal (3, Fig. C).
2. Lift the brush/pad-holder deck and the squeegee by
pressing the switch (4, Fig. B).
3. Drive the machine to the appointed disposal area.
4. Empty the recovery water tank through the hose (10, Fig.
C). After working, rinse the tank with clean water.
Solution or washing water tank emptying
5. Carry out steps 1 to 3.
6. Empty the solution or washing water tank using the tap
(24, Fig. C). After working, rinse the tank with clean
water.
